Wolves come in a wide variety of sizes and colours.

I’m back to posting on my blog . . . .I hope to post regularly, but also likely infrequently.

Blogging is, or can be, hard work. Still, I’m doing it because it can provide a forum for ideas that hopefully helps more than just me in understanding events that are of concern to a lot of us. Certainly, I am a follower of several blogs and I get some very interesting and useful information from them.

At any rate, the reason(s) I’m going to try this (blogging) again is that I can’t help but be astounded at some of the going-ons in wildlife world. Wolf management, for example.

Let’s look at that one. It’s appropriate, I think, especially given that I’ve always had a photo of a wolf as the ‘signature’ of my blog.

I have used a wolf photo, in part, because wolves evoke a wide range of thoughts and ideas amongst anyone with an interest in wild things. It’s been that way for a long time – as the song says, “it’s been that way since the get-go.”

Historically, wolves were believed to be ‘bad’ by the majority of people, at least in Europe (those North American ‘colonizers’) and getting rid of wolves was ‘good’. It’s not hard to see how those ideas came to be, considering rural folk in Europe, for hundreds and even thousands of years, were mostly poor, didn’t have guns and were often reliant on a farming existence that was quite fragile. Wolves killed and ate livestock and back in those days, probably killed and ate more than a few people. So it made a lot of sense to try and get rid of wolves; which they did, eventually.

While this was going-on, Europeans began colonizing North America, bringing along with them their ideas about what to do about wolves (get rid of them).

Which, again, they did; much of what became the lower 48 along with large swaths of southern Canada became wolf-free zones.

But there were still a lot of wolves in the world and the wolf did not go extinct.

In Eurasia, large numbers of wolves continued to persist, particularly in Russia; in Canada and Alaska, wolves have always ranged far and wide.

With wolves gone across large landscapes, but still abundant elsewhere, the ‘let’s get rid of all the wolves’ meme lost pre-eminence.

It was replaced by the ‘we like wolves a lot!’ meme.

One outcome was a re-classification of the wolf. In the minds of both the public and government, the wolf changed from being a lowly varmint to the more lofty status of a noble game animal. To provide them with love and protection, wolves, in places, were put on endangered species lists, which brought with it money and the implementation of many a wolf recovery program.

Largely a result of the new meme, wolves today are more widespread and abundant than they have been in over a hundred years.

They’re back with a vengeance in the western mountains of the US, much of the mid-western forests and are occasionally reported in New England.  Of course, there still abundant over much of Canada and Alaska.

And coyotes are almost everywhere outside the tundra. Then there are wolves that people don’t really know how to classify except to say they’re some sort of wolf . . . Newfoundland, once free of all wild canids, now has coyotes and . . .some other canids.

Over in Europe, wolves have also been on the path to recovery. Hiking their way across and out of Poland, wolves have successfully recolonized Germany, to the point where there is now a growing rumbling that wolf numbers are getting out of control. In late 2017, there were estimated to be 60 packs of wolves in Germany, 13 more than the year before. The total number of wolves is officially estimated to be 150-160, although unofficial estimates say there is more than twice that number. Wolves are also showing up in other European countries, including France and Spain.

With many landscapes now occupied (infested?) with wolves, I think it’s time to move away from ‘we like wolves a lot!’

Unfortunately, that meme is not yet dead, although it has been wounded.

For example, the old mantra that wolves only kill the very old, the very young, the sick and the injured has been thoroughly de-bunked.

Wolves will try and catch and kill and eat whatever they can.

In the mountains of northern Idaho and southern British Columbia, the South Selkirk herd of caribou is down to three animals. What’s the main culprit behind their disappearance, despite decades of effort at maintaining and increasing their numbers?  Wolf predation. Even though it is astounding that wolf culls were actually attempted, they weren’t successful in getting rid of the wolves there (maybe it’s a lost art) and so the wolves have been catching, killing and eating all the caribou.

In Canada’s Pukaskwa National Park on the northern shore of Lake Superior, the wolves finally caught and killed and ate every last caribou a few years ago.

This past winter, Ontario did an emergency capture and transfer of caribou off Michipicoten Island. This was done because it was feared wolves there were going to catch and kill and eat all the caribou on the island.

So it’s clear that wolves can drive herds of ungulates, at least locally, to extinction.

It’s also become clear that in addition to killing them all, wolves are capable of killing enough to reduce populations to low levels and then keep them there. It’s called a predator pit – after falling in, there’s no way out. It’s been observed with respect to white-tailed deer in the northern forests of Minnesota and a number of small, scattered herds of woodland caribou wherever they occur.

That’s proof of the pudding that there is no ‘balance’ of nature. Nature is never ‘in balance’. There is a constant struggle for survival that goes on and in the end, most species actually lose out. There are vastly more species that have gone extinct than survive today. And the vast majority of extinctions have had nothing to do with, to use a phrase, humankind.

So knowing what we now know, I think it’s time to get rid of and replace ‘we like wolves a lot!’ with something a bit more reasonable. A lot of people are thinking along those lines.

Something is needed that will result in changes to the present, often absurd, over-protection of wolves way of doing things.

Like here in Ontario, where moose populations have been in decline for years despite severe and increasing restrictions on hunting. The answer seems to be to give wolves even more protection.

Now there’s a proposal in the works to ban wolf harvest completely from a huge swath in the south-central part of the province to protect the ‘eastern’ wolf, something that, with some half-hearted scrutiny, can be shown to be completely bogus, as there is no such animal. The ‘eastern’ wolf, described in part as a rather smallish wolf, occurs sympatrically with gray (timber) wolves. The wolves breed indiscriminately with one another and produce viable offspring of various size and colour. Biology 101 says that makes them the same species. But when you’re hitched to the ‘we like wolves a lot!’ bandwagon, you don’t let sound science get in your way.

It’s worth noting that scientists in the USA, who have analyzed the data, don’t recognize the eastern wolf as a separate species of wolf. They are more along the lines of wolves being Canis soup.

Over in Germany, wolves are still provided with complete protection. With numbers rapidly expanding, there are dire consequences to wild herds of deer and livestock being predicted.

Fighting over how to manage wolves in the US continue to escalate; in some areas,elk herds are taking a pounding from high wolf predation.

With all these conflicts, one would think that reasonable compromises regarding wolf management could be found, but none appear to be anywhere, at least not on the immediate horizon.

So despite all the evidence that shows there is absolutely no doubt that there can be too many wolves and that managing wolves using sound wildlife management  should be a no-brainer, the ‘we like wolves a lot!’ continues to rule the day. It can’t last . . .

Meanwhile, over on Isle Royale National Park in Lake Superior, the wolf population – which arrived naturally – is down to a single animal. The Isle, which got rid of all the wolves naturally, pushed the US Parks Service to produce plans to re-introduce 20-30 wolves to the island over the next three years at a cost of about 2 million dollars.

I really think it’s time to change that meme.

Well, that’s my back to blogging post. Hope you enjoyed it.

A free-range Red Hartebeest, hunted and harvested on a cattle farm.

A good comprehension of the answers to the question ‘who owns the wildlife’ is fundamental in understanding how wildlife is managed around the world. Despite the vast number of people, communities, corporations, agencies and governments that that have vested interests and ownership of wild animals, there are only two broad approaches under which wildlife management practices can be categorized, namely public versus private ownership of wildlife.

In North America, the model generally followed is public ownership. That is, the government owns the wildlife, regardless of whether the animals live on public (e.g., federal, state or Crown land) or private land. Under this scenario, government is largely responsible for monitoring and management of wildlife. This happened mostly because the early European colonialists came from countries where wildlife was owned by royalty – Kings Queens, Earls and such – and common folk had little access to wildlife, unless they were poachers. So when they came to North America, the people were bound and determined not to see that system happen again.

However, at first there simply were no laws. Even when governments were created and game laws were passed, most were quite lax. As a result, many populations of wildlife, especially those that were exploited for their meat, hides or feathers, saw catastrophic collapse; some, like the passenger pigeon, went extinct. Bison, which once numbered in the tens of millions, almost suffered the same fate. Beavers were almost gone. Large predators (e.g., wolves and bears) were wiped out over vast tracts of land. The slaughter was intense, especially in the late 1800’s – by the early 1900’s, wildlife was in a sorry state in much of the USA and southern Canada.

Fortunately, saner minds prevailed and actions were taken before it was too late. The banning of commercial hunting was a key in the recovery of many species. Over the past 100 years, there have been great strides in conserving and restoring many populations of wildlife in the USA and Canada. Proponents of the North American approach to public ownership of wildlife claim it’s a model that works and they’re largely right.

Still, all is not rosy with respect to wildlife management in North America. Large predators like wolves and bears remain absent over large expanses of their former range as the public simply won’t or can’t tolerate their presence. The same is true of other game species; for example, it’s unlikely that free—ranging bison will ever be seen on the prairies again. Herds of free-range bison and activities like grain farming are for the most part incompatible, so bison today are found only in selected places like parks and protected areas, or on private, fenced in lands.

Interestingly, bison, elk and other animals are today being commercially raised – by private interests – and their meat and other parts sold for profit. In fact, there are a growing number of private lands in both Canada and the USA that are fenced in and where hunting and access are limited for a wide variety of wildlife species.

It’s unclear as to what wildlife management in North America will look like in the future. While federal and provincial governments are still mostly responsible for wildlife conservation and management, there is a shift in Canada and the USA to give individuals and other private interests more responsibilities and rights to use wildlife, including Aboriginal governments and communities.  There’s little doubt changes are looming and how wildlife will be managed and allocated in the future, may have little resemblance to what we have today.

The second model by which wildlife today is managed has private interests owning and managing wildlife. Governments still have a role and may still have wildlife ownership in places like National Parks, but elsewhere, where land is owned by private interests, landowners also own the wildlife. That’s the situation in Namibia, where I recently hunted.

Writing in HUNTiNAMIBIA 2017, Dr. Chis Brown of the Namibian Chamber of Environment showed changes in wildlife numbers in Namibia from about 1770 to 2015. At the start of that time period, it’s thought there were around 8-10 million animals in the country. Numbers declined steadily until the 1960’s, when the animal population was estimated to an all-time low of about a half million.

In the 1960s and 1990s, rights to use wildlife to support a multi-faceted business model were given to farmers. As a result, farmers (for the most part livestock – cattle – farmers; in North America the equivalent would be cattle ranchers) could provide trophy hunting, sport hunting and use wildlife meat for food, including for sale. Surplus animals could be captured and sold. Some landowners have moved on from cattle farming and wildlife is now the primary source of income and the priority with respect to land-use decisions.

In 2015, wildlife numbers in Namibia were estimated at 3 million, the highest since the 1960s.

As one would expect, Namibia sees their wildlife model as a success. South Africa has a similar model and is also largely successful

Again, not all is rosy. Many farmers don’t like predators like lions, cheetahs or leopards for the same reasons wolves and bears aren’t liked by North American farmers. There are also concerns that the widespread use of game-proof fencing cuts off large scale movements of wildlife, an adaptation many species evolved with to survive in an arid environment prone to drought. Other issues involve world trade sanctions for species like elephants and rhino, which need to be managed – but any efforts to manage such huge species are also very costly. Namibia is one of the few places left on the planet with wild populations of cheetahs and black rhinos, but the country is finding it difficult to maintain them because of the actions from the rest of the world with respect to hunting and sale of wildlife, are more a hindrance than a help.

Public vs private ownership of wildlife; two very different approaches to how society provides for the management of wildlife. Both have strong points; both have weaknesses. I suspect that as time passes, we’ll see the two systems increasingly converge.

deer-53

Lil and I applied for a moose tag the other day. The chances of getting a tag look slim. In Kenora District, where we live, the 3 WMUs have a combined quota of 3 bull moose, one for each WMU. There are more tags to the east, but because of that – and it isn’t like there are a whole bunch of tags – the demand still far outstrips the supply.

It still seems weird to me that only 1 bull tag (no cow tags) is allocated in those WMU’s, but there is a two week calf season with no quota on the number of calves hunters can take. And 1 tag sounds fishy to me. Even if the population was only 10 moose, taking 1 bull would still allow the population to grow, and I know, and the MNRF knows, there’s more than 100 moose in WMU 6.

Of course, Aboriginals, including Métis, have no seasons or limits on moose, or anything else for that matter. So licensed hunters are the ones that suffer, and it may not do the moose population any good, depending on what happens with the native harvest. It’s no way to manage wildlife.

It also seems to contradict our Prime Minister, who proudly says “A Canadian is a Canadian is a Canadian”.  Err, not really, not when it comes to rights and freedoms, which is what that mantra is supposedly all about.

Oh well, not much I can do about that. Sadly, the number of people who want to address the issue is small in this country. Someday it’s going to be a big issue and resolving it won’t be pretty.

Meanwhile, Lil and I have been entertained by the ducks in the beaver pond out front of the house. Most days there are buffleheads, ring-necks, mallards, green-winged teal, wood ducks and hooded mergansers there, in addition to a pair of nesting Canada geese. No sign of the blue-winged teal yet. And the only shore birds I’ve seen are a solitary sandpiper and a couple of common snipe (and we’ve heard, of course, a number of peenting woodcock). But it’s early yet, so we’re sure to see some other species in the weeks to come.

A peregrine took a run at the pigeons that frequent the yard the other day, but didn’t appear to get one.

Oh, and the timber wolves are still around.

Lil was outside when the dogs started barking like craze, so she walked down to the end of the driveway – less than 100 meters – and saw some fresh wolf tracks on the road. Soon, the dogs were barking like crazy again, and when she checked, saw another set of wolf tracks. That’s when she called me to have a look.

We went out to the road and were looking at the tracks and it seemed they had been chasing a deer. I looked up and exclaimed –“There’s a wolf now!” It crossed the hydro line and walked out on the road, and then another one came out on the road a bit behind. They didn’t seem to be bothered by us; ambling off slowly when we yelled at them.

A couple of days later some deer showed up and one had a huge patch of fur missing off its side with noticeable scabbing. We thought the wolves would get it that night, but it’s been around for several days now. Some of the deer that were almost daily visitors during the winter months have disappeared, though. Of course, that doesn’t mean the wolves got them – they could just be dispersed since it’s almost fawning time.

Still no sign of moose.

moose-5

Wildlife has been in the news quite a bit recently.

Some of it has been revolving around Parks Canada and worries about a suspected onslaught of visitors this summer. Then there was the good news story about the return of bison to Banff. There’s bound to be a continued focus on Canada’s national park system as Canada celebrates its 150th Anniversary since Confederation.

Moose made it to national radio one morning on ‘The Current’ (see – http://www.cbc.ca/listen/shows/the-current/segment/11611043). The show managed to mix in some cultural relevancy and worrisome declines in Canada’s moose population. It was Ontario focused, although a moose expert from British Columbia provided the western perspective and there were light ties to national implications.

The moose story got rolling when the Wildlands League, a chapter of CPAWS (the Canadian Parks and Wilderness Society), put out a press release calling on the Ontario government to ‘ban’ the hunting of calf moose by licensed hunters (here’s a link to their site –  http://wildlandsleague.org/project/moose/).

A slew of articles, interviews and broadcasts that followed were basically successful in discussing the fact that in Ontario, as well as some other parts of Canada, moose are in a steep population decline. Mentioned, but much less discussed, was how in other parts of Canada, moose are thriving. But whatever, there are concerns about what needs to be done to address moose decline. Exactly what should be done, though, has become the bigger problem.

Legal, but largely unregulated night hunting by Aboriginals, often called jacklighting when it’s done by poachers, also made the national news.

In this case it was mostly because the new Premiere, Brian Pallister, suggested the night hunting that has been going on in the province, particularly in the agricultural south-west, was in danger of inviting a ‘race war’. The progressive press was quick to pick that up and race and identity instantly became the story. The problem of night hunting – elk, moose and often big, trophy whitetails – was sort of lost in the kerfuffle with calls on the premiere to apologize for his incendiary, comment grabbing headlines.

Still, Dr. Vince Crichton, who’s in the midst of this milieu, tells me there are many Aboriginal people, including Chiefs, other leaders and elders, who want and know that something needs to be done. Apparently, the Premiere is also committed to finding a solution.

For the courts, using a 10 million candle power spotlight to light up a field to let one shoot game with a scoped, high-powered, centre fire rife is okay, as long as it’s done in a safe manner. That’s because they’ve made rulings that such a practice respects Aboriginal Rights as specified in the Constitution, in part because the practice is consistent with traditions and appeases spiritual needs.

Night hunting as a traditional practice is legal in most of Canada, although it isn’t allowed in the neighboring province of Saskatchewan.

In Ontario, small game hunting was in the news, but only if you looked for it. Ontario had a EBR posting on small game management proposals that ran until about the end of January, with some of the proposed ‘actions’ to be implemented as early as this fall. That’s means it was on the internet and the public was consulted by being invited to comment on the proposals.

One thing that caught my eye was a proposal that would see the whole province (every WMU) with a 10 pheasant a day limit, with no restrictions on sex, and all that during a very lengthy season.

Obviously the provincial wildlife managers have sided with the deep ecologists, and don’t want to expend time and effort trying to manage an ‘alien, invasive species’ just so hunters can pursue them. Because pheasants aren’t native, they ‘don’t belong’ here and getting rid of them, or at least making sure there’s next to no chance of having a self-sustaining population, is just the right thing to do. It’s one step towards the restoration of the landscape and ecosystem in southern Ontario that was in place in the pre-colonial days.

Not everyone agrees with that approach. But managing for hunters is unlikely to be a priority for the ruling Liberals, who are foundering in the polls, facing an election and trying to boost their popularity.

So Ontario has problems with small game as well as moose. Hard to say what they might do.

All in all, an interesting past couple of weeks; I’ll need to see what happens next. There’s sure to be at least some changes in the weeks and months ahead.

swallows-23

A barn swallow, not near a barn.

I’m a hunter. I spend a lot of time thinking about hunting. I think I’m from the old school of wildlifers who went to the wildlife management profession because I was and still am a hunter. There are still some of us around.

I recall learning that managing wildlife and hunting was a close tie because in general, the people who were most passionate about wildlife were hunters. If you didn’t hunt, there were better things to do than spend a career trying to manage wildlife.

The reason the people who were managing wildlife in the early days – and for a long time afterwards – is rooted in history. Lots of people knew there was a wanton slaughter of wildlife going on, but it wasn’t going to stop until hunters themselves put a stop to it. And that’s what happened.

Hunters demanded new rules and regulations, because they knew hunting was a problem.

Over time, the management of wildlife became increasingly complex. But for a long time, the focus was the management of game animals and hunters. And most Provinces and States maintained Game Departments.

Some of the first changes began a few decades ago when Game Departments started to see themselves merged with other departments or agencies with environmental responsibilities.

Once that happened, the tide turned away from hunting, hunters and game.

Hunting, though, is still a problem.

And it’s not getting the attention it needs, in part because hunters don’t have near the clout they used to have in government wildlife management circles.

The focus today is on non-game species, often species identified as a ‘species at risk’ (which suggests that unless something is done, that species could become extinct . . . go the way of the Dodo).

These days, the majority of employees in wildlife management agencies are non-hunters and many studied non-game species during their formal studies in college and university.

A consequence of having a lot of people involved in non-game management – and a lot of interest to be involved in that field – is it creates pressure for non-game departments to grow and expand their budget. That’s just the way government works.

There can be consequences. One that many of my colleagues and I see is a growing trend to identify and categorize more and more species as being ‘at risk’, even if they really aren’t.

Let’s look at the barn swallow as an example as to the point I’m trying to make.

To start, guess where barn swallows nest?

Barns! However, the kind of barns barn swallows like – big and airy with haylofts – no longer dot the countryside. They’ve been falling down for years and aren’t being replaced. Fewer barns, fewer barn swallows.

But barn swallows don’t just nest in barns – before the days of barns, they had to have been nesting in other places.

The fact is, there still are a lot of barn swallows nesting and flying around the countryside. Just not as many as there were back when barns were common..

But because the decline – in some places – was large and is still on-going, the powers that be have decided there must be a problem. In Ontario, the barn swallow is listed as being threatened with extinction. COSEWIC, the Committee on the Status of Endangered Wildlife in Canada, also lists it as Threatened.

The Cornell Lab of Ornithology, though, one of the most prestigious institutions in North America in bird studies, says this about the barn swallow:

“The Barn Swallow is the most abundant and widely distributed swallow species in the world. It breeds throughout the Northern Hemisphere and winters in much of the Southern Hemisphere.”

Here’s the link. https://www.allaboutbirds.org/guide/barn_swallow/lifehistory

As a species, the barn swallow is in no danger of extinction. True, its numbers are down – maybe precipitously in some places – but is the species really in trouble? It’s the “most abundant and widely distributed swallow species in the world”.

Lots of money is being spent on barn swallows, wood turtles, whip-poor-wills and many, many more non-game species. A lot of that is a ‘good thing’. But it’s not all good.

These non-game species programs cost a lot of money. Managing game costs money too, but game management also generates a lot of money. Lots. There’s not much money to be made managing barn swallows.

If we did a better job of managing game animals, there’d be more money for all sorts of wildlife management. But managing wildlife, in large part for hunters, isn’t ‘cool’. It’s ‘icky’.

There’s no doubt in my mind game species and hunters are too often getting the short shrift.

Hunters and not a small number of non-hunters, know this isn’t right, but don’t know what to do.

Better game management makes economic, environmental and social sense.

In many areas it even has the potential to improve race relations.

It’s just the right thing to do.

shrike-1

Shrikes seem to be fairly common where I live. That’s the northern shrike (Lánius excúbitar), one of two species found in North America. My old field guide to the birds says the northern shrike is ‘a rare robin-sized bird’; according to the International Union for Conservation of Nature and Natural Resources (IUCN) they are a species of least concern, so I take it they’re a species believed to be in good shape.

The northern shrike breeds in the far north, but migrates to more southerly climes to spend the winter. Ones I see are likely both migrants and winter residents, seeing as we live well south of where they breed, but just on the northern fringe of where they winter.

This time of the year they’re feeding on small birds and rodents like mice and voles. I suspect the one I’ve seen several times over the past little while is checking out the birds that hang around the feeder; particularly the black-capped chickadees, redpolls and red-breasted nuthatches. To date, I haven’t seen it catch anything.

The other shrike species is the loggerhead shrike (Lánius ludoviciánus). My field guide calls them uncommon; the Ontario Field Ornithologists report they’re listed as Endangered under Ontario’s Endangered Species Act, although in North America as a whole they are still fairly numerous, albeit populations have declined noticeable since the 1960’s. Authorities estimate there are about 5.8 million loggerhead shrikes (breeding population); as such, they are not in imminent danger of extinction, rather they are a ‘common bird in steep decline’. A breakdown as to where they are is as follows; 82% spend some part of the year in the U.S., 30% in Mexico, and 3% breed in Canada.

In Ontario loggerheads occur mostly in two grassland habitats – the Carden Plain north of Lindsay and the Napanee Limestone Plain; both areas are in eastern Ontario.

A number of reasons have been put forward regarding the declining numbers of loggerhead shrike. One I put a lot of credence in is the loss of habitat. Much of the habitat ‘loss’, I believe, is affiliated with changing farming practices: many farmers used to graze cattle in woodlots, which led to many farms having thorn bushes, like hawthorns, become the prominent woody shrub. But farming associations said this was poor farming practice and a variety of incentives has, over time, resulted in farmers clearing the land, converting grazed woodlots into pasture.

Loggerhead shrikes liked the heavily grazed woodlots, open pasture, not so much. I suspect loggerhead shrikes in North America initially benefitted from poor grazing practices and mushroomed far over their baseline. In this context, their decline is not too alarming, at least not yet.

Interestingly, there was pressure on Ontario farmers who still had loggerhead shrikes to keep their heavily grazed woodlots as this was deemed to be ‘critical habitat’ under species at risk legislation. It caused a furor (governments telling farmers what to do!) and helped fuel the Ontario Landowners Association’s property rights movement and their slogan ‘This Land is Our Land’ , followed by the tagline ‘Government Keep Off!’.

As I said, where I live, there seems to be only northern shrikes. And no angry, shriking farmers.

moosehunt-7

I just returned from Brandon, where the 50th Annual North American Moose Conference and the 8th International Moose Symposium were combined and held. There were people from North America and Eurasia attending the meetings, but I only managed to intermingle for a short while; I was a one day attendant during a set of meetings, field trips and social events that lasted several days. I really enjoyed myself and it seemed to me that was the feeling that captured the general mood.

I heard several talks about moose and listening to those presentations was like music to my ears. I heard that as a species, moose seem to be faring well, although populations in some areas have declined precipitously. I live in one of those areas – northwestern Ontario – I was there to provide an overview of the factors driving moose and white-tailed deer populations in the Kenora District of Ontario.

I don’t think my presentation was quite as lucid as I had hoped and I know I made an error when I couldn’t see the labelling on one of the graphs I had inserted into the power point presentation. Unable to read the labels and the legend, I promptly got the deer and moose stats wrong. Oh well, that will be corrected during the final write-up and anyway,  I think the crowd got the gist of my presentation.

It’s still an emerging consensus, but it appears that in much of eastern North America’s moose range, moose populations are limited by the presence of a parasite called brain worm. In that eastern, wetter, more highly forested biome, the parasite is commonly found in populations of white-tailed deer, where it seems to affect deer minimally, if at all. However, when moose become infected with brain worm, the animal often dies.

In the western, drier and more open ranges of North America, there is little to no incidence of brain worm in deer or moose. The presence of brain worm seems to do a good job of helping to explain how moose populations are compromised by high populations of deer.

It seems that in the east, once deer densities exceed about 4 deer/km2, moose populations decline. When deer densities are low, rates of transmission of the parasite from deer to moose rarely occurs.

There’s a lot more to the stories on moose and deer dynamics, but one of the topics of interest is how moose recover from low densities. In western Manitoba, southern Saskatchewan and south-eastern Alberta – the Canadian prairies – the thinking is that moose populations have been on the rise coincident with a decline in the number of rural farmers and ranchers living on the landscape. There’s evidence that incidence of illegal, unregulated hunting wasn’t necessarily high, as moose populations were long-depressed in the prairies, but it didn’t take a lot of moose hunting to keep populations low. As people abandoned their homesteads, more and more moose managed to find refuge and survive. Today, moose populations in grain and cattle country are robust.

The eastern forest areas where moose have recently declined are the same areas where deer populations simultaneously surged. But recent winter of deep snow and cold have knocked deer populations back; if they stay low or decline further, moose populations may be poised to recover.

A growing concern is that where moose populations are lowest, recovery could be jeopardized by legal, but unregulated hunting (Aboriginals and Metis have the constitutional Right to hunt and fish; the present interpretation is this means the hunting of moose by some can be done at any time of the year and there are no seasons or bag limits on the harvest).

The moose harvest by such individuals may not have to be much to prevent severely depressed moose populations from recovery.

Unregulated hunting is certainly not the only issue regarding moose population (or other game species) recovery dynamics. But to help solve the puzzle as to how to effectively manage moose populations in particular, it’s a factor that needs a lot more attention than society at large has lately been willing to give it.
