Honey Bees on Vancouver Island / Tugwell Creek Honey
Farm & Meadery Producer/Host - Jon Steinman Transcript - Tia Alexander Jon Steinman: And welcome to
Deconstructing Dinner - a syndicated weekly radio show produced in Nelson,
British Columbia at Kootenay Co-op Radio CJLY. I'm Jon Steinman and for the
next hour we'll be exploring the latest setback in the ongoing struggle
to maintain healthy honey bee populations around the world. Every winter
honey bee farmers hope that come spring, their colonies will have survived so
that their businesses can remain economically viable. And with Vancouver Island
receiving spring the earliest of any location in Canada, farmers there
are reporting catastrophic results from the winter with some farmers having
lost up to 90% of their colonies. Yet while populations elsewhere in Canada
have also been hit in recent years, it appears (at least at this point), that
Vancouver Island's significant losses are an isolated incident.
Nevertheless these recurring losses to beekeepers have become an increasingly
major issue of concern around the world for both honey producers and other
farmers who rely on honey bee colonies to pollinate their crops. On today's
episode we'll speak with British Columbia's Provincial Apiculturist Paul van Westendorp (apiculture being the practice of beekeeping). Paul
will share his thoughts on the most recent collapse of colonies on Vancouver
Island and he'll share insights into what measures beekeepers are taking in
response. And just as the most common and immediate responses to these types of
threats are often simple band-aid solutions, we'll also examine whether
the collapse of honey bees around the world is the canary in the coal mine -
signaling to us that perhaps our practices of agriculture and land-use
management are in desperate need of a foundational rethink. And
we'll also travel to Vancouver Island to meet Bob Liptrot
of Tugwell Creek Honey Farm & Meadery.
Bob was one of the many foodies and farmers who Deconstructing Dinner visited
in the community of Sooke back in February. Tugwell Creek has in no way been immune to the collapse of
colonies on the Island, with their operation having suffered an
estimated loss of at least 65% of their bees. But regardless of the grim
challenges facing Tugwell Creek, we'll receive some
enjoyment with a tasty and fascinating introduction into mead, also known as
honey wine - a product that Tugwell Creek specializes
in producing. In fact, their meadery was the first of
its kind in Western Canada. increase music and fade out/sounds of bees JS: Apiculture - a little known term, yet its role in ensuring that our current food system is able to continue to function as is, ranks up there with the importance of oil. Apiculture is more commonly referred to among us eaters as beekeeping and the practice of humans raising bees has knowingly been going on for a few thousand years, and since its beginnings, apiculture has evolved quite synchronistically alongside agriculture enabling the models of food production we see today. Despite most eaters associating beekeeping with the production of honey, honey bee colonies are significantly more important as pollinators of many of the crops ending up on our dinner plates. In Canada, as an example, one third of the foods cultivated here are reliant on what the industry refers to as "managed pollination". Whereas in the wild, flowering plants are pollinated by wild bees/insects, birds and the wind, managed pollination using honey bees has allowed for large tracts of land to be devoted to single crops as we see today. The models of industrial agriculture dominating our food system have effectively wiped out much of the natural habitat for wild pollinators that would be necessary to pollinate those foods, but more foundationally, natural systems that have not been the product of human intervention would never be home to the sheer number of flowers found on an apple orchard, a field of canola or rows of blueberries. And so, enter the honey bee, who ensures that those foods get pollinated and produce fruit or seeds. Honey
bees are also not native to North America. It was in the 1600's when the
first honey bees were brought over from Europe and used commercially.
Additional bees were introduced from Italy in the mid 1800's, and later imports
came from Spain and Portugal. And while the introduction of a non-native
species into North America was not surprisingly without its challenges, it's
only been in recent years that those challenges have reached almost
catastrophic proportions. It
had become a standard in the industry for beekeepers to expect a loss of about
15% of their colonies over the winter, but the colony losses have increased
substantially in recent years. Last year as an example (the 2008-2009 winter
season) resulted in colony losses across the country in the area of 40% on
Prince Edward Island, 43% in New Brunswick, 29% in Nova Scotia, 32% Quebec, 31%
Ontario, 32% Manitoba, 25% Saskatchewan, 44% in Alberta and 24% in British
Columbia. That brought the national average of colony losses in that year to
34%. The previous year's national losses were 35% and the year prior 29%. Now
economically speaking, these previous years have placed many beekeepers into a
pretty precarious position, it's just not sustainable for a beekeeping business
to lose the amount of their colonies that they've been losing. The latest area
of the country to be hit hard with colony losses is Vancouver Island, with
producers there reporting colony losses of up to 90%. At
the forefront of the response to this challenge is, among others, Paul van Westendorp. He's the Provincial Apiculturist for the
Province of British Columbia as part of the Ministry of Agriculture and Lands
and he's been with the program for over 20 years. Previous to his current work
Paul was in the same capacity for the Province of Alberta. He's worked on
beekeeping programs in Uganda and has also worked for Canada's Ministry of
Agriculture and Agri-Food's apiculture research
station in Beaverlodge, Alberta. Paul
spoke to Deconstructing Dinner over the phone from his office in Abbotsford. He
spoke about the province's apiculture program itself and he also stressed that
the latest challenges facing beekeepers throughout North America in particular
really began back in the 1980s when a particular parasitic mite was first
introduced onto the continent. Paul Van Westendorp: Much of the architectural design, if you will, of the apiculture program
was established after the Second World War when a lot of people came back from
the war and agriculture in the province started to expand rapidly. And so with
increase food production and agricultural activities like that, beekeeping
expansion went hand in hand. And beekeeping has always been, you might say,
largely a complementary component to the agricultural sector. And therefore, in a technical sense, we have always
viewed honey production as a byproduct. It may be very important for the
individual beekeeper to produce as much honey as possible but from an
agricultural perspective, honey bees are far more important as pollinators of
insect pollination-dependent crops. And I'm talking here of course about food
production and things like this. And so the apiculture program has always focused on
assisting the beekeeping community to reduce or to prevent the occurrence of
diseases. And this has been always very stable because there were only a very
few diseases that played a significant role in all of this essentially until
the mid to late 1980's. That was the time when the parasitic mites were
introduced into British Columbia and they came up from the United States and
that has basically altered the beekeeping industry forever. It truly has lost,
you might say, its innocence. While in the past beekeeping has been somewhat of
a pastoral pursuit that was somewhat romantic and the techniques that were
involved quite simple, (some people would describe that as rustic) but since
the mites have come into being and has chastised honey bees, today this unique
form of animal husbandry (what beekeeping is) has become an extraordinarily
complex and demanding activity that requires a far greater knowledge base than
what has ever been in the past. JS: As Paul Van Westendorp
introduces, beekeeping is much more important as a complimentary sector for
agriculture as a whole than it is a sector for producing honey and honey
products. Paul expands on this role and he compares the size of the BC Apiculture
sector versus neighbouring Alberta. PvW: The total beekeeping industry here in British
Columbia is small in comparison to Alberta. Alberta has by far the largest
beekeeping industry in the country. In Alberta you have approximately 750
beekeepers that operate over 250,000 colonies but we have here topography and a
climate that wouldn't allow that to happen. Here we have much more specialized
smaller enterprises that fulfill a critical role in many of the crops that are
grown out here. And we have, you know, close to 2000 beekeepers in the province
instead of 750. But we here in British Columbia (beekeepers, well if I can say
it) only operate approximately 40 to 45,000 colonies. But much of the emphasis
is placed on pollination and to illustrate the size of it, the beekeeping
industry of British Columbia has a total annual value of approximately $10 to
$12 million worth of produce in the form of hive products like honey and pollen
and wax and things of that kind. When we compare that with the actual number of
crops that are grown in this province annually that are totally, you know,
pollination-dependent, that amounts to about $250 million dollars. So we have
here a ratio of approximately 1:25 or 1:22 or somewhere in there in terms of
value and you have to see bees that they function as a sparkplug to our
agriculture. Most of the blueberries that are grown out here in
the early season here in the Fraser Valley for example are highly dependent on
the presence of honey bees in sufficient numbers to meet the crop pollination
requirements. And of course in the Okanagan, as you well know, it's to do with
the tree fruits that are grown out there. The apples and the pears and all
those are very much dependent on the presence of bees and without them this is
going to be a problem. So our focus in our program has always been to try to
assist beekeepers to be the best possible operators and to have them operate
healthy colonies and colonies that are strong enough in the spring to be rented
out or to be used for the purposes of crop pollination. And of course over the
course of the season (the beekeeping season) beekeepers manage their colonies
largely towards honey production. And of course the honey is of course a very
important income source for the beekeepers. JS: This is Deconstructing Dinner. Clearly beekeeping plays a critical role
in ensuring a multitude of crops get pollinated. As mentioned earlier, one
third of all of Canada's food crops require pollination services from managed honey
bee colonies. And so the threats posed by their significant losses each winter
can mean very noticeable ripple effects throughout the food system. While the
suggested reasons for the colony collapses are many and varied, the most immediate
and accepted culprit has been a parasitic mite. Known as the Varroa Mite, it first appeared in Japan and the then-USSR
in the early 1960s. It then spread gradually around the globe arriving in
Eastern Europe in the 60s thru the 70s and then into Brazil in 1971, the rest
of South America by the late 1970s. Western Europe began noticing it throughout
the 1980s and then it arrived in the United States in 1987, Canada in 1989,
England in 1992, New Zealand's North Island in the year 2000 the South Island
by 2006 and the latest, the Hawaiian Islands in 2007. Australia is the only
place in the world currently free of the Varroa Mite.
Here again is Paul van Westendorp
- British Columbia's Provincial Apiculturist. PvW: In the late 80's when the parasitic mites came into
the province and we are talking about two mites. One of them is a microscopic
mite that lives inside of the breathing tubes of the honey bee, of the adult honey
bee, and it is called a Tracheal mite. It appears that our honey bee strains
have for the most part have developed a reasonable level of resistance to this
particular microscopic mite. The other mite is called a Varroa
mite and the Varroa mite is a very large mite that
live only on the outside of honey bees and also parasitizes the brewed of honey
bees. And this is an extremely destructive pathogen. When it comes into your
colony the beekeeper must do something about it and if he or she does not then
there is a guaranteed outcome. And that outcome is that the colony will die. So
beekeepers have in the 1980's onward have applied a number of control products
that control these mites quite successfully. And keep in mind beekeepers only
apply these products at a time when the honey bees are not involved in making
honey that ultimately will be used for human consumption. So they apply these
things, let's say, in the fall after all the honey have been taking off and in
the early spring before the bees are starting to produce honey. And then they
can apply these products to the bees in the hope that these mites will be
subdued and will not create havoc later on in the season. This has been reasonably successful for about ten
years after the introduction of these mites but slowly by the year 2000 we
started to see that these mites have started to develop some form of resistance
to some of these products. Now, it's not just merely the term of damage that
these mites have inflicted on the bees that have been of great concern but now
it appears that there have also been the introduction of various other
microbial organisms and I'm talking here about a specialized fungus. It's a microsporidian with the name called Nosema
that is creating problems in the bees. But most importantly there have also
been the introduction of a number of viruses, bee viruses. And in the past
before the mites came into our population (bee population) these viruses had a
tough time to get access to the bees because they have a pretty formidable hard
skin. Not like all insects do, they have an exoskeleton with the skeleton on
the outside so the viruses did not have an easy way of getting into the body
cavity of these bees and create all the problems. But we have learnt here at the
tests that we do here in the Animal Health Center here in Abbotsford and
discovered that these viruses are actively transmitted by the Varroa mites themselves. In other words, the Varroa mites are not suffering any ill effects of these
viruses but with their feeding habits they introduce the viruses straight into
the bodies of the bees. And we believe that it is a combination of these
various pathogens that has caused an even greater death among colonies than
what they were initially when we only dealt with Varroa
mites. And so what beekeepers can do is not that much other than to ensure that
the strength and the health of the bees are as good and as best as possible.
And that is in part accomplished through good management practices. JS: Paul van Westendorp. Paul
is the Provincial Apiculturist with the Ministry of Agriculture and Lands for
the Province of British Columbia. On today's broadcast of Deconstructing Dinner we're
exploring the significant collapse of honey bees throughout North America with
a focus on Vancouver Island, where beekeepers there are suffering from recent
losses of up to 90% of their colonies. In the second half of the show we'll travel
to Vancouver Island and visit Tugwell Creek - a honey
farm that is also British Columbia's first meadery
(mead being honey wine). But first, back to Paul van Westendorp,
as Paul indicates, the primary culprit resulting in the disappearance of honey bees,
the parasitic Varroa mite, is not new, it's been
plaguing farmers across the continent since the late 1980s. But the response until now has been more of a
band-aid solution to what might be a much more foundational problem. This has
been a recurring topic here on the show that our food system has evolved to be
more at war with nature than it is a series of systems working with it.
Instead of stepping back and questioning the very foundations of our food and
agricultural systems, our approach has tended to be more of a quick fix (the
latest advances in ammunition so to speak). Of course our war on nature has not been possible
without the help of chemicals, and sure enough in the case of beekeeping,
chemical controls have become essential in order for the current systems of
beekeeping to continue to function. The most commonly used miticides
in beekeeping have been Apistan and CheckMite, but as Paul introduced, resistance to these
products was confirmed in 2001. Prior to that discovery, another chemical
- Coumaphos, was not registered for use in Canada.
Instead, emergency use permits were required by beekeepers before it could be
used, and only if Apistan resistance was
demonstrated in the region. So here we begin to see the same cycle that we so
often have seen in the food system, where instead of questioning whether the
food system models themselves are in need of reform, the chemical or controls
that cease to work, are replaced by another chemical one that is perhaps
more toxic and the use of which might result in negative impacts that are less
known and unpredictable. And so it's no surprise, that in 2002 in Ontario, Varroa mites there were too discovered to have become
resistant to the emergency-use-only Coumaphos
chemical. That resistance is now present throughout most of Canada. So what's
next in the chemical arsenal? Well, some Canadian beekeepers, in fact many have
been using the latest ammo - a neurotoxin known as Amitraz
- it's used around the world on livestock and orchards and now increasingly for
honey bees. But despite the product not being permitted in some regions around
the world, for honey bee use, Canada did between 2008-2009, issue emergency-use
registrations of the chemical and then again for the current 2009-2010 season.
And so here again, the cycle continues. More chemicals, and most certainly,
more resistance to them. And while Canadian beekeepers were permitted
to use Amitraz, in places like Washington State, the
Department of Agriculture there has maintained a strong stance that prohibits
its use by beekeepers. It appears that some beekeepers there have been
navigating around the law resulting in a January 2010 release by the
Department stating in strong words that, "pesticides containing Amitraz for control of Varroa
mites in honey bee colonies is illegal. Amitraz
is not labeled for use on honey bees and there are no tolerances for residues
of Amitraz in honey or honey comb. Honey or honeycomb
that is found to be contaminated with residues of Amitraz
is subject to regulatory action by the US Food and Drug Administration and the
Washington State Department of Agriculture." So while chemical responses to the threat to honey
bee colonies are and have been widespread, there are other non-chemical
responses underway that will be touched on later on the show. But let's narrow
in on Vancouver Island, the focus of the show today because it's there that
this past winter saw the loss of upwards to 90% of the colonies on the Island.
It's a statistic that would be even more frightening if it was a sign of the
magnitude of losses across the country, and so Deconstructing Dinner asked BC's
Provincial Apiculturist Paul van Westendorp if the
high losses on Vancouver Island are isolated? PvW: At this point in time we do not know. We don't have
scientific data to substantiate a claim that says yes there's something unique,
biotic let's say, and the biotic factor that has been introduced on the island
and it is nowhere else to be found and therefore they have these problems, or
it is a combination of various factors that may have led to this massive
decline in colonies this last winter on Vancouver Island. And I'd like to point
out something that maybe illustrates the difficulty that beekeepers face today
in comparison to what it was in the past. To illustrate this thing about
Vancouver Island we have this suspicion, but we don't know that for sure, that
of course it was the Varroa mites certainly had some
major role in all of this, but it could have well has been that there were
other factors such as these viruses playing a role. And also things such as this last summer your
listeners can well remember that we had an exceptionally warm and dry summer
that extended well into the fall. So what beekeepers found, at least on
Vancouver Island, that they still had what we call a honey flow which is an
incorrect name because bees do not collect honey they collect nectar and they
make honey; however, we call them honey flow. That they were still into a late
honey flow, well into the early fall. Well that had two consequences. One of
them was is that they had to delay their mite control treatments later into the
fall which they would otherwise have done earlier in the late summer. That
could have had an impact on the efficacy of these treatments. So when you wait
too long you will have different temperature regimes. The colonies are going to
go into different phases or conditions and as result you may not be able to get
as much of a bang out of your mite control treatment than you would have had if
you would have applied it earlier. That's one thing. The other thing is a more
physiological thing. Bees face a huge stress period when they have to go as a
colony through the winter season. So the honey bees that are born in the early
fall are the ones that are needed are basically the adult population that will
winter the colony, through the winter. When the late summer is there, these
bees by instinct will work very hard to collect all that nectar and that pollen
and whatever is available. So they are expanding their physical resources on
collecting food rather than preserving it for wintering successfully. And I recall years ago we did some trials in Alberta
(going through records there as well years before that) and discovered that
there is a correlation between late summer honey flows or late summer honey
production and poor wintering results in the winter that follows such a summer.
If you have a summer that stops earlier in the season then the bees can
preserve their strength better, you might say, and survive the subsequent
winter far better. And it could well have been that on Vancouver Island such a
scenario actually took place. JS: Paul also indicated that it appears at this point
that the honey bee colonies on the mainland of British Columbia have
maintained healthy populations over winter. Now while it's easy to point the finger of
disappearing honey bees to the Varroa mite, as
suggested earlier, the mite itself and its threat to honey bees is likely a symptom
of a more significant and underlying problem. This too came up in my
conversation with Paul. We spoke of the models of industrial agriculture
themselves, as possible reasons for the disappearance of honey bees.
With agricultural models having become so intensified to single crops, we've
effectively demanded that bees fit into these industrial models of agriculture.
In Alberta as an example, of the 240,000 colonies there, about 60,000 of them
are contracted out to pollinate hybrid canola which is dependent on
pollinators. With those similar demands come possible nutrient deficiencies
among the bees and increased stress. And Paul explains. PvW: If bee colonies are continuously moved around only
to access a number of commercially grown crops, then perhaps, are they getting
enough of the nutrients they are supposed to get? I mean we all know that
carrots are very healthy to eat but if I only eat carrots and nothing else,
apart from my skin colour, I may well get very sick.
Likewise with the bees. And this is particularly prevalent in the United States
where these colonies are moved all over the continent all the time to a select
number of crops and it could well be that nutritional deficiency plays a role
in all of this. Not only that, we also have become exceptionally demanding of
our bees something that they have not been designed to do. You know, bees are
not doing very well when they spend most of their lives on the back of a truck
crisscrossing the country on super highways. So, maybe we apply way too much
stress to these bees. Now, these practices are not nearly as prevalent
here in Canada and here in British Columbia but certainly these things will
undoubtedly play a role as well. As it is with every organism, be it animal or
human or whatever, if we apply confused stress on the organism then it becomes
more vulnerable to infection and to disease. Its immune system is compromised
or is weakened and it becomes then far more vulnerable to the actions of
pathogens that are taking advantage of the situation. And that is one of the
reasons why much of our educational efforts that are directed to beekeepers is
to try to have them manage bees as good as possible by reducing stress, by
applying hygienic management practices and we are also looking at the
possibility (and there is widespread belief) that perhaps we have selected the
genetics of bees in such a way that they have become rather sensitive to all
these natural predators. Maybe we should go back to more natural bees if it is
in itself a huge topic but the genetics of bees is another thing that is widely
discussed and looked at. So, ultimately miticides/mite
controlling chemicals are not the answer. The answer ultimately lies in relying
on the natural defenses of the honey bee. And hopefully these technics will
become available to beekeepers soon. JS: Now beyond some of the more specific challenges
facing honey bee populations (nutrient deficiencies, poor genetics, stress,
parasitic mites and viruses) we haven't yet spoken of climate change as yet
another possible factor. The impact of climate change on pollinators (both wild
and domesticated) is such a serious concern that NASA is paying considerable
attention to it. And so we have here a short clip produced by NASA that does a
nice job introducing the challenges that bees are believed to already be facing
by a changing climate. NASA clip (music in background): Over millennia, pollinators like honey bees have evolved a well-timed
dance with plants. But now, plants may be changing their tune. Spring green-up;
when plants wake from winter and sprout leaves, it's such a global phenomenon
that NASA satellites can see it from space. Sensors, such as Modis on NASA's AQUA and TERRA
satellites, can show us how green our planet is throughout the year - and
they've captured something strange. In the Northern U.S., spring green-up is
starting about a half-day earlier each year. The likely cause; our warming
climate. But is pollination also moving earlier? The images can't detect
individual flowers, so scientists have been left to guess until now. NASA research scientist Wayne Esaias
spearheads a special team gathering data directly in the field. They're the
honey bees in his Maryland backyard. Wayne Esaias: "Honey
bees are great data collectors for understanding the processes of pollination.
Bees fly two and a half miles in all directions to scout for bee forage and
bring back pollen and nectar. So therefore they sample a very large range of
environments." By weighing the hives, Wayne can detect when nectar peaks
and ebbs each year. "During the winter, the hive loses weight as they eat
the honey to feed the babies and keep warm. And then when plants start blooming
in abundance, the hive starts gaining weight. It can gain a tremendous amount
of weight. I've had a hive gain 25 pounds in one day." Wayne's been keeping tabs on his bees for less than
twenty years. But in that time, pollination has moved more than ten days
earlier. "That's completely in sync with what the satellite data record shows
- the world here getting greener earlier in the spring by about a half a day a
year…If we have a few scale hive measurements with the wall-to-wall coverage of
the satellite, we can then extrapolate those scale hive measurement of when the
nectar flows occur to very large areas of the country." Now, to get a
bee's eye perspective of how pollination is changing in very different
environments - say, deserts or mountains - Wayne's doing a little networking. "HoneyBeeNet is a
network of citizen-scientist beekeepers that volunteered to weigh their hives
to give us more data points, to see how the nectar flows are changing in all
different parts of the country." If pollination dates keep creeping
forward, plants and pollinators could move out of sync. Currently, young bees
are able to grow and get out on the hunt by the time plants bloom. But if
plants bloom before bees are ready, both miss out. The plants don't get
pollinated, and the bees go hungry. But more than just bees might miss a meal.
NASA satellites can help us understand how climate change might affect what's
on our dinner table. "Modern agriculture requires bees as part of
the production. It's as mandatory for food production as is pieces of
irrigation pipe and fuel for tractors. So if we're to understand the impact of
climate change on our ecosystems, we must understand how this plant-pollinator
interaction is being impacted by climate change." JS: This is Deconstructing Dinner, a syndicated weekly

honey bee colonies around the world with a focus on Vancouver Island, where
this year up to 90% of colonies did not survive the winter. To explore this
latest setback to the industry we've been hearing from Paul van Westendorp. Paul is the Provincial Apiculturist with the
Province of British Columbia's Ministry of Agriculture and Lands. He spoke to
us over the phone from his office in Abbotsford. But to bring a more personal account of the
challenges facing beekeepers on Vancouver Island, we can travel to Tugwell Creek Honey Farm and Meadery.
We've been focusing quite a bit lately on the show about the local food
movement in the small community of Sooke where Tugwell Creek is also located. Bob Liptrot
is a co-owner of the operation with his wife Dana. They've been at their
current location for 12 years and began raising bees a year after they arrived.
About 7 years ago they diversified their operation and began producing mead, also
known as honey wine. They became the province's first licensed meadery. Deconstructing Dinner visited the farm in February
2010. Bob Liptrot: Well, we're at the top of the farm right now looking down towards the
Strait of Juan de Fuca and across the way over in the clouds the United States
and Washington State, the Olympic Peninsula. We have a little over 12 acre farm
here with a salmon stream that flows through the bottom portion of it. We keep
about 2/3 of it in an undeveloped stage to provide habitat for our bees and
wildlife. We have several overwintering yards and right now it's a bit cold so
the bees aren't flying too much. They need to be out in about 13-14 degree
weather right now to fly and we're just a bit below that but there's a few bees
flying on the heather blossoms right now I see. We have around 40 colonies in
our overwintering yard at the moment at the farm here and we have 2 other
overwintering yards with a similar number of colonies in those yards too.
Because you can't keep too many bees in one location, we've spread the
overwintering colonies out into friend's farms. One is over towards Sooke Pot Holes about 10km away from here as the bee flies
and another one is at a friend's farm out behind us about 3km away. I started working with bees as conscripted child labour in East Vancouver back in the early 60's. My passion
with bees has continued on since then periodically having other jobs in between
but always having bee hives in one place or another. We now run a bee farm
which is what we do for a living. We don't have other jobs now. We're farming
approximately a 100 plus production colonies so it's a very small farm by North
American standards but it's very intense. We also breed bees with the idea in
mind of hopefully starting to breed more mite resistant and tougher honey bees.
I think Southern Vancouver Island is a great spot to
raise bees. We have tremendous nectar resources here, very mild climate for
raising bees. Most of the country in the middle of February is still under snow
or at least too cold to have bees flying. Right now we currently have bees
flying and blossoms out and so it's a good place to raise bees. We have some
very interesting nectar that lend themselves to good honey and even better mead
once it's converted. Nectars that we primarily find around here are
blackberry (first in season); Eurasian blackberries. We also find Salal blossoms, trailing blackberry up in the mountains
(wild blackberry) and we get quite a lot of fireweed later in the year and
that's probably the largest percentage of our crop. JS: Bob Liptrot of Tugwell Creek Honey Farm and Meadery.
Located on Vancouver Island, Tugwell Creek has not
been immune to the challenges that have plagued beekeepers on the Island over
this past winter. BL: The challenges are always many and varied. We
currently on the Island are going through quite a lot of bee loss right now and
largely that's been attributed to a very destructive mite called Varroa Destructor, oddly enough. It is an introduced mite.
It's been in the province and in Canada in general since the early 80's. It has
caused tremendous losses. This year alone on the southern portion of Vancouver
Island, I would say the losses will come out somewhere around 85% of every
colony of pretty much every beekeeper will be destroyed. This year has been
particularly bad for us. We've lost probably around 65% of our colonies
possibly more, the wintering season isn't over yet. It is without a doubt an
issue that is a major economic hardship for us as with any beekeeper. You can't
expect people to keep losing 65 or 75% of their business and keep farming
indefinitely. That's why we're looking more intensely at bee-breeding programs
and better livestock management, better nutritional management and just working
towards that end rather than the negative side of continued miticide
use and chemical use. JS: As introduced earlier on the show, honey bee
colonies are much more valued for their role as pollinators of food crops
(orchards, oilseeds, vegetables), but according to Bob Liptrot,
Vancouver Island is not as affected by the loss of pollinators as other more
intensively farmed regions. BL: The real pollination end of it on the island isn't
a huge thing. There's not a lot of crop pollination going on compared to the
Prairie Provinces or Northern BC where there is a lot of industrial intensive
agriculture but we do pollinate orchards on the island here. Lots of berry crops are pollinated. There's also a
certain amount of cranberry pollination which goes on and of course there's the
overall general pollination that even a backyard beekeeper provides with one or
two colonies to the overall neighbourhood for people
growing all sorts of different types of fruits. Right from tomatoes and squash
all the way on up through to the big old family apple tree in the backyard.
Without those colonies being present that pollination ceases to exist. We then
fall back on natural pollinators more and in a lot of cases natural pollinators
are also suffering due to the overuse of pesticides and the loss of habitat. JS: This is Deconstructing Dinner. We're hearing clips
from my visit with Bob Liptrot of Tugwell
Creek Honey Farm and Meadery located in Sooke on Vancouver Island, British Columbia. Similar to my
earlier conversation with Provincial Apiculturist Paul van Westendorp,
I also spoke with Bob about the reasons for the disappearance of honey bee
colonies on the Island. While the Varroa mite
is the direct culprit, Bob too believes there are some more underlying
concerns that have led to the challenges facing Island beekeepers there and
throughout North America. BL: It's a multitude of reasons. There's no doubt there
is a lot of contributing factors. It's not as simple as just one particular
problem. We have a lot of intensive beekeeping going on in order to pollinate
the intensive agricultural processes that we currently are embarked upon. That
intensive beekeeping is primarily wrapped around pollination which for the
North American industry alone is over a 40 billion dollar industry. It
encompasses all sorts of crops and it uses well in access of three million
colonies of bees every year to pollinate crops from as far south as Florida and
as far north in the Peace River area of British Columbia and right across the
prairies and into Ontario and of course the Maritimes as well. So all of these intensive agricultural crops are
dependent upon migratory beekeeping processes and of course those migratory
beekeeping processes not only move bees around but also parasites and pathogens
that come with those bees and that of course help to spread the problem around
quite a bit. JS: Bob Liptrot agrees that until now the response to the mite problem has been met with
a silver-bullet approach with the hope that chemical miticides
would solve the problem. As mentioned earlier, these efforts while once effective are no longer, as the
mites have developed resistance to the chemicals. Instead Bob believes better
bee breeding programs are
necessary to encourage mite-resistance. But even more foundational, I asked Bob
if he believes the collapse of honey bee populations might be the canary in the
coal mine, warning us that the models of agriculture themselves that the bees
help support, are themselves the problem. BL: It's no doubt an issue that does lead one to think
that we might be canary in the coal mine in this process. We definitely are
running into other issues such as climate change. We're running into perhaps
the overuse of pesticides and fertilizers, the overuse of particular crop
programs on certain types of land that are perhaps marginal at best for those
crops. Perhaps we need to rethink our agricultural processes in some cases and
take a step back from the intensive models that we're currently embracing and
look at something a little less intensive. The same holds true for the
beekeeping industry. Perhaps we need to step back from the operations that have
30 and 40,000 colonies and travel around the countryside pollinating this, that
and everything. It's a difficult process though to step back from something
that has been going on for many years and in some cases decades. It's not going
to happen overnight. Typically we find in countries where there is a little
less industrialized agriculture we also find in the beekeeping industry a
little less issues with things like colony-collapse disorder. So there may be
something to the simplification of agriculture. Most certainly keeping things
in agriculture a little less intensive will also help to provide greater
habitat for other pollinators, which are currently under threat as well. JS: Another issue that has not been raised on today's
episode and is one deserving of more attention perhaps on a later show, is the
decline in natural wild pollinators that have resulted in an increased
reliance on managed pollination such as the honey bee colonies trucked
from farm to farm. Bob introduces this concern. BL: Prior to intensive colony management that we're
relying on now for beekeeping and pollination directly, we were more reliant
upon bumble bee species, upon certain wasp species, certain solitary bee
species, and even things like hummingbirds, moths, even bat species. With the
intensive models of agriculture that we're embracing and the intensive land use
that goes along with it, we've lost a lot of natural habitat that those species
depend on and as a result we've lost a lot of those species, or they're on the
decline, and therefore that makes us more dependent upon artificial species or
farmed species like the European honey bee that most beekeepers use. JS: This is Deconstructing Dinner. If you've missed any
of today's one-hour feature on honey bees, today's episode is archive on-line
at deconstructingdinner.ca and posted under the March 18th, 2010 broadcast. And to close out our focus on the collapsing
populations of honey bees, it's worth touching on how farmers who rely
on honey bees to pollinate their crops are responding. Last year as an
example there was a substantial shortage of pollinators in British
Columbia, and farmers located in the Fraser Valley, the Okanagan Valley and the
Creston Valley instead relied on large colonies that were trucked in from
Alberta. Certainly this acted as an emergency response, but no doubt is not
a response farmers in BC should feel comfortable relying upon for the
long-term. But let's move on from the challenges facing
beekeepers and focus more on what we eaters get to benefit from as far
as beekeeping is concerned. Of course we do benefit from the crops the
bees are pollinating, but we also get to enjoy honey, honeycomb, and products
like mead (also known as honey wine). Tugwell Creek
happens to be British Columbia's first licensed meadery
and we'll learn more about that in just a moment. But first, the honey itself,
Bob Liptrot shared some interesting information with
Deconstructing Dinner about the differences between generic honey found
on grocery store shelves and those found from individual small-scale
operations. Here again is Bob Liptrot. BL: generally when people are buying honey of a generic
sort of grocery store shelf with generic packaging on it, they are purchasing
honey which is blended quite often or they're purchasing honey which is
imported from offshore resources such as places like China or some areas like
South America where there may be slightly different standards for honey
production and it is being imported through honey packers. There is certainly food
security measures in place through Canadian Food Inspection Agency but they're
quite often importing honey which may not be of higher quality and that's one
of the reason why it gets blended by honey brokers and honey packers and
shipped around the country for various uses. You pay for what you get. When
you're buying honey from a small producer you're generally buying honey from
somebody who is intimately acquainted with what the bees are foraging on. Quite
often you're buying varietal honey and honey which is of a vastly superior
quality to the generics of blended from many different sources. JS: Tugwell Creek markets a
number of honey products, beeswax, honeycomb, candles, but they're increasing
focus over the past seven years has been mead (honey wine). In 2003, Tugwell Creek became Western Canada's first meadery and the results have been very successful. Bob Liptrot introduces Deconstructing Dinner to this ancient
beverage and he pours us some samples of their meads. BL: Mead is the oldest started fermentation that is a
lot of things to a lot of different people. In some parts of the world it is a
very light ale like product. In other parts of the world it's more like a
fortified liqueur. We make it as a wine style. It can be made as cider style.
There is no end to variation on it. Our main focus, and my family's main focus
over the last 50 or so years of making mead has been to make it more as a wine
style although we do do some of the other types as
well. Our family's been producing several different types
of mead over the last 50 or so years and I've been involved in that part of it
for probably closer to 30 years now messing around with different types of
mead, experimenting with different formats. We currently are producing around 5
or 6 different types of mead. The types of meads that we're pouring right now are melomels, which are a berry based mead using fruit which we
produce right here on the farm. We also pick fruit from around the farm here
too and we also produce metheglins which are a spiced
based mead and we have a couple different types of metheglin
that we pour. The one that is being poured right now which is a sparkling metheglin and very old, authentic, Old World style of mead
that goes back into the 1560's and is based on very old recipes from the Dutch
East Indies Company books. Basically what we're doing to get a mead is bringing
a certain amount of honey in from our production line. Typically in a given
year we'll produce in the neighborhood of around 2000 kilos of honey. In an
average year 2 to 3000 kilos and we dedicate a percentage of that of course to
making mead for us. And the styles of mead we make we usually put anywhere from
about 0.2 to 0.3 of a kilo of honey into every litre
of mead that we produce. So we're using quite a lot of honey and I think that
helps to set our meads apart from other meads on the market. We're also using
some fairly intensive wine techniques for fermenting and one of the things our
family's been doing for years is also fermenting using French oak barrels and
aging in French oak barrels which I think adds an interesting and complex to
mention to mead production. Some of our meads will typically age out to well
beyond 25yrs while some others are intended to be consumed and enjoyed within
the first few years of their life. We've recently released our first vintage
for public consumption. It's not the first one we've made but the first vintage
for public consumption of a fortified mead using our own distilled spirits from
mead itself. Classically, most people think of mead as being very
thick and viscous, syrupy liqueur like product and it certainly can be that
way. I typically don't make meads that way too much. It's not something that
the general public consumes too much. I think they prefer lighter styles of
mead in this part of the world so our meads are made with the same specific
gravity as you would expect from any table wine. Most of our production now is
ranging in the dry to off dry and it's more than suitable for enjoying with
casual dining or with formal dining. The first mead I'm pouring you here is our Harvest Melomel and the Harvest Melomel
is a classic mead that we've been producing for many years in the family. It's
a very light, fruity style of mead. It's a very low key mead made with three
different berries which we grow right here on the farm. We always use the same
three berries in production. That's Marion, Logan, and Gooseberry but we use Wildflower
honey in this. For us on the Island, Wildflower honey is primarily salal and fireweed. So this next mead that is being poured is our
Wassail Gold and Wassail Gold is a very delicate sparkling mead and it's made
with an old family recipe that goes back over 50 years in our family. It is
made with Fireweed honey. We use 6 different spices all from the West Indies,
and aging and fermenting in French oak for over 14 months to produce a very
delicate light sparkle. This is one of the only meads now that we do in an
unfiltered style in keeping with its heritage of the 1560's roughly. The date
is a fairly known factor for us because it was extracted from a recipe that was
recorded in the Dutch East Indies Company books. So we've modified it very
little in the course of 50 or so years that it's been made. This mead I've just poured you is a Brazen
Blackberry. Brazen Blackberry is an interesting mead. It's one of those meads
that kind of goes full circle for us. We have made it to an off dry level about
six months aging in French oak barrels and it's made with local blackberries
that are picked around the hedge rose around the farms here and lots of
Blackberry honey. So from the point of view of being a blackberry mead it
catches blackberry in all stages. It's interesting that the bees are not only
getting the Blackberry nectar and producing honey from it but in the process of
doing that and collecting blackberry honey for our production they're setting
the fruit for later that we go to pick and make the wine from. So it's a nice
mead, a little more serious coming in at around 14% alcohol. It's something
that typically gets paired with the main course of a meal. JS: That was Bob Liptrot here
