WCS Canada comments on Canada's Critical Minerals Strategy, to Natural Resources Canada

The federal government’s draft Critical Minerals Strategy is structured around colonial ‘new frontiers’ mindset that leads to a focus on expediting extraction instead of understanding the real consequences of opening up some of the world’s last remaining ecologically intact areas and carbon-rich stores to industrial development.

The Fawn River Indigenous Protected Area (IPA) Ecological Atlas

The Fawn River Indigenous Protected Area (IPA) Ecological Atlas is the product of a collaboration between Kitchenuhmaykoosib Inninuwug (KI) and Wildlife Conservation Society (WCS) Canada. Our goal in producing the Atlas was to continue to advance scientific support for the Fawn River IPA in order to complement and advance KI’s vision for protecting their homelands.

Ship noise sends belugas scrambling out of the way

In a new study, scientists led by Morgan Martin, a zoologist with Wildlife Conservation Society Canada, reveal in unprecedented detail how belugas will flee, dive, and otherwise rush to escape the distressing din of shipping noise.

Nesting Ecology of the Barn Swallow on Agriultural Lands in Yukon
ince the 1980s, the abundance of the Barn Swallow (Hirundo rus-tica) in North America, including the far north, has declined. To better understand the species’ biology north of 60° N, near the northern limit of its range, and in a region of expanding agriculture, we studied its nesting ecology on farms in southern Yukon Territory, Canada, in 2019 and 2020. We followed 21 attempted nests in 2019, 20 in 2020, of which 52% and 60%, respectively, were inside buildings with permanently open entrances. Other nests were built on the outside of buildings. In both years we inferred successful double brooding by three pairs, which is rarely reported north of 60°N latitude. We found the swallows’ reproductive output to be similar to that at temperate latitudes: first clutches ranged from three to six eggs (mean 4.8 in 2019; 4.2 in 2020); second clutches may have averaged marginally smaller (n = 6). The mean number of fledglings per nest was 3.3 in 2019 and 3.0 in 2020. Twenty-one percent of nests failed, either by falling off a vertical substrate or because of predation by deer mice (Peromyscus spp.), Black-billed Magpies (Pica hudsonia), or domestic cats. We also compared the air temperatures at nests, usually near building roofs, to ambient temperatures, finding them on average 1.6°C warmer than temperatures outside buildings. We set out 33 platforms and 20 wooden cups designed for Barn Swallow nesting but over the two years of our study the birds did not use any of them.

Joint Comment ERO - 019-6160 Proposed Update to the Ontario Wetland Evaluation System
We, the 70 undersigned organizations, are strongly opposed to the Ministry of Natural Resources and Forestry's (MNRF) proposed changes to the Ontario Wetland Evaluation System (OWES), as they would completely undermine the protection of wetlands in Ontario. As you know, the OWES is a science-based ranking system that provides a standardized approach to determining the relative value of wetlands. OWES assessments are necessary to designate Provincially Significant Wetlands (PSWs). This designation in turn results in a high level of protection under provincial law and policy such as the Provincial Policy Statement (sections 2.1.4, 2.1.5 and 2.1.8). Yet the complete overhaul of the OWES, as proposed, will ensure that very few wetlands would be deemed provincially significant in the future and that many if not most existing PSWs could lose that designation. As a result, very few of Ontario's wetlands would benefit in the future from the protection that PSW designation currently provides. We urge you not to proceed with the proposed changes to the OWES, for the reasons outlined below.
WCS Canada to Canada re COP19 CITES_2022-10-14
This is a response to the notice of Environment and Climate Change Canada (ECCC) regarding species proposals in advance of 19th meeting of the Conference of the Parties (CoP18) to CITES. This letter contains recommendations regarding select working documents and species proposals in three parts: 1) WCS overall recommendations (53 pp) 2) Letter to Fisheries and Oceans Canada, with Oceans North, on the matter of shark proposals, dated 21 July 2022 3) Letter to Fisheries and Oceans Canada, with Oceans North, on the matter of shark proposals, dated 29 July 2022
Joint Comment - WCS+Oceans North Letter2 to Canada re CITES CoP19 Shark Proposals September 2022
A follow-up to the joint comment from July 2022 and discussion had on August 17th, regarding the shark proposals being tabled and discussed at the upcoming 19th meeting of the Conference of the Parties (CoP19) to the Convention on International Trade in Endangered Species of Wild Fauna and Flora (CITES). We appreciate your openness, and of course your consideration of these proposals. We are writing to provide you with additional information that has since become available. We call your attention to the recent assessments of these proposals by the CITES Secretariat, IUCN/TRAFFIC and the UN Food and Agriculture Organization (FAO), which we know Canada will consider carefully in developing its positions for CITES CoP19.
