The vast boreal forests and wetlands of the far north in Ontario represent one of the largest intact areas left on the planet. But major new resource development and infrastructure projects are on the horizon. We need to know more about this region and its wild inhabitants in order to plan for a future where wildlife thrives, and people continue to benefit from healthy lands and waters.
Rigorous multi-year wildlife surveys undertaken by WCS Canada have helped fill in some of the knowledge gaps and have shown the importance of this area as a refuge for species that have lost populations in areas further south, such as caribou and wolverine. The region boasts some of the most pristine and undammed freshwater rivers and lakes in North America and is home to more than 50 species of fish, including ancient sturgeon. Our scientific modelling work in this region has helped identify areas that are critical for the protection of sensitive fish species already grappling with the impacts of climate change.
The mountains, plateaus, and forested valleys of northern BC and Yukon are another globally important wild area with a relatively light (for now) human footprint. In Yukon, we have mapped “the best of the best” of the territory’s extensive wild habitat to help inform efforts by both the territorial government and Indigenous communities to develop new protected areas. The territorial and First Nation governments negotiate land-use plans with new protected areas, and we provide technical support to the First Nations and conservation advice to the planning processes. Beyond protected areas, our sights have been focused on improvements to policy and legislation, including fighting large-scale hydro-electric developments, reducing disturbance to wildlife, and getting protections for wetlands. Our passion is to do hands-on research with species that are key to conserving certain ecosystems such as lakes and wetlands (breeding birds, river otters), that are particularly sensitive to current threats (salmon, grizzly bears), or are keystone species in ecosystem processes (snowshoe hares, beavers).
Canada’s arctic region is warming faster than almost any other place on Earth. The rapidly changing climate is reshaping both land and marine environments in the Arctic and may be doing so at a pace that will make it difficult for some species to adapt. While action to address climate-disrupting emissions remains critical, we must also prepare for inevitable changes to Arctic ecosystems. One of these is a loss of sea ice and a resultant increase in ship traffic through the Arctic as shippers pursue a shorter connection between Europe and Asia. Impacts on marine mammals from increased ship traffic could include deadly collisions and disturbance by ship noise.
Loss of sea ice will also increase ambient noise in the Arctic, which points to the importance of addressing cumulative impacts and putting solutions in place before problems grow even larger. Our acoustic monitoring work on marine mammals is helping us assess current and future noise impacts on whales and seals and to make recommendations for how to manage growing ship traffic. We also have a long-term community-based monitoring program in place to assess ice-seal population health and diet, recognizing how any disruption to seal populations could affect the people for whom they are a dietary staple across the Arctic. We are also using findings about seal diet to help monitor how the Arctic marine ecosystem is changing.
In the past, protected areas were often designed as much to reduce conflict with resource industries (forestry, mining) as to protect biodiversity. This has led to parks that may be scenic, but limited in species diversity or lacking in ecosystem representation. With habitat loss and degradation being the principal cause of biodiversity decline in Canada, area-based conservation strategies remain important. Yet, as Canada moves to meet its goal of protecting 30% of its lands and waters by 2030, we need to be sure the same mistakes are not made again. Our protected area systems must do a much better job of helping species and ecosystems survive. And we must look beyond protected areas to improve conservation outcomes across our natural and developed landscapes.
The Key Biodiversity Areas (KBA) Canada Program, part of the international KBA initiative, is one significant tool driving this shift in protection and conservation priorities. The KBA program starts with knowledge gathering and we have developed a wide network of information sources on species and ecosystems across Canada. We have also developed new systems for making this collective information more accessible to everyone in the conservation community.
Working with local experts, governments and Indigenous communities, we identify areas that harbour rare, threatened and endemic species and ecosystems, significant populations of key species, and areas with exceptionally high ecological integrity that can play a key role in protecting biodiversity. To date, we have identified more than 200 sites that we believe require special conservation attention across Canada and now have regional processes in place to identify many more.
Canada has some of the largest remaining wild areas left on the planet. But monitoring the health of these vast areas, including deep forests, wetlands and peatlands and thousands of lakes and rivers can be challenging. That is why WCS Canada scientists look at specific species as indicators for the health of broader systems. Species such as caribou, wolverine, bison, birds and freshwater fish can help us understand how systems are faring because they need large wild spaces, healthy rivers, lakes and forests. Caribou and wolverine, for example, are sensitive to disturbance by resource industries and may disappear from areas that become heavily fragmented by roads, logging and mining. Freshwater fish require good water quality and the ability to migrate up or down river from spawning sites. Bison can be a critical element in restoring now rare grassland systems.
Caribou: We continue to fight for effective recovery plans for threatened caribou across Canada and protection of remaining habitat. Meanwhile, our work on areas like the Muskwa-Kechika in BC focuses on saving intact habitat for healthy caribou herds, which are disappearing in more southerly parts of the BC.
Wolverine: Our team has tracked wolverines across northwestern Ontario for three winters, using a combination of live traps, hair snag traps, and camera traps to better understand wolverine movements and habitat use. We have already made recommendations on how to change forestry practices to help protect wolverine dens and will continue to use our scientific findings to advocate for evidence-based policies for management of boreal wolverine populations. This finer-scale work builds on the seven-year aerial survey effort we undertook to better determine where wolverines were in northern Ontario and whether their range was expanding.
Freshwater Fish: Working with the Moose Cree community in northern Ontario, we studied the impact of hydroelectric development on sturgeon to highlight the importance of undammed rivers to this ancient species. Our freshwater fish research aims to protect species that have both ecological and cultural importance.
Birds: Many bird populations have experienced steep population declines over the past 50 years thanks to everything from habitat loss and pesticides to collisions with buildings and power lines. We are interested in addressing the issue of habitat loss in the boreal nesting ground used by millions of songbirds each year and along critical migration corridors, such as the Tintina Trench in Yukon. By documenting bird movements – including the amazing migratory journey of the blackpoll warbler – and habitat use, we can make the case for protecting forests that function as huge bird nurseries.
Bison: Working with our U.S. colleagues in WCS, we have helped revive the American Bison Society and hosted an annual gathering to discuss how to restore bison that included everyone from ranchers and First Nations to scientists and park staff.
White-nose syndrome (WNS), a fungal disease that spreads among bats during hibernation, has wiped out millions of bats in eastern North America, landing species such as the little brown myotis on the national endangered species list. The disease has been steadily spreading west and it is almost inevitable that it will eventually reach Alberta and BC (it is now confirmed in Manitoba, Montana and Washington). These two provinces — and BC in particular — have very high levels of species diversity for bats. Bats play an important insect control role in ecosystems and provide us with millions of dollars of pest control services. Despite being long-lived mammals, bats do not get the care and attention more charismatic species receive and have seen a steady loss of habitat and hibernation sites, particularly in old buildings. Our bat program is racing to understand more about the vulnerability of western bats to WNS, monitoring bat status through the innovative and wide reaching North American Bat Monitoring Program, and looking at ways to restore and protect habitat, including developing best practices for bat houses.
