The current distribution of the Eastern Milksnake within its known range in Canada is not fully understood and there is insufficient information available to assess trends in the species' abundance or distribution. It also occurs in southwestern Quebec, particularly near Montreal, Montérégie, and the Gatineau areas. In Canada, the Eastern Milksnake ranges throughout southern Ontario as far north as Sault Ste. The Eastern Milksnake (Lampropeltis triangulum) is a non-venomous constrictor in the family Colubridae. Contributions and advice from Sylvain Giguère, Mark Dionne, and Gabrielle Fortin (Environment Canada, Canadian Wildlife Service – Quebec), Karine Bériault (Ontario Ministry of Natural Resources), James Paterson (Ontario Nature), conservation data centers and herpetofunal atlas projects are also gratefully acknowledged.Īcknowledgement and thanks is given to all other parties that provided advice and input used to help inform the development of this management plan including various Aboriginal organizations and individuals, individual citizens, and stakeholders who provided input and/or participated in consultation meetings. It was updated and revised by Rachel deCatanzaro and Lee Voisin (Environment Canada, Canadian Wildlife Service – Ontario), Tianna Burke, and Louis Gagnon (formerly of Environment Canada, Canadian Wildlife Service – Ontario). Pearce (Pearce and Associates Ecological Research) and David Anthony Kirk (Aquila Conservation and Environment Consulting) with input and direction from Angela McConnell (Environment Canada, Canadian Wildlife Service – Ontario). This management plan was drafted by Jennie L.
Implementation of this management plan is subject to appropriations, priorities, and budgetary constraints of the participating jurisdictions and organizations. All Canadians are invited to join in supporting and implementing this management plan for the benefit of the Eastern Milksnake and Canadian society as a whole. Success in the conservation of this species depends on the commitment and cooperation of many different constituencies that will be involved in implementing the directions set out in this management plan and will not be achieved by Environment Canada, or any other jurisdiction alone. To the extent possible, it has been prepared in cooperation with the Government of Ontario and the Government of Quebec. The Minister of the Environment and Minister responsible for Parks Canada Agency is the competent minister under SARA for the Eastern Milksnake and has prepared this management plan as per section 65 of SARA. 2002, c.29) (SARA), the federal competent ministers are responsible for the preparation of management plans for listed species of special concern and are required to report on progress within five years after the publication of the final document on the SAR Public Registry. Because of this overproduction in non-venomous snakes, over time, ones with the more favorable mutations (such as becoming more similar in appearance to the poisonous snakes) survive longer to reproduce more offspring with those traits.īecause looking like the coral snake is a favorable trait that should increase the chances of survival in the desert, the mountain snakes, the milk snakes, and shovel-nosed snakes are equally hunted as the coral snakes (around 0.01-0.03 units consumed/day).The federal, provincial, and territorial government signatories under the Accord for the Protection of Species at Risk (1996) agreed to establish complementary legislation and programs that provide for effective protection of species at risk throughout Canada. This will confuse the predators of which snake is which, especially because the milk snake and mountain king snake are not as densely populated as the coral snake (0.8 individuals/mi2 and 0.3 individuals/mi2 versus 2.2 individuals/ mi2 and 2.7 individuals/mi2).Īlso, the non-venomous snakes have an advantage in that they reproduce triple+ the amount of offspring as the poisonous snakes. The Sonoran Coral snake is distributed all over the deserts, while the other snakes (the mountain snake, the milk snake, and shovel-nosed snake) only take up sections of the whole desert. The non-venomous snakes and the venomous snakes live in the same environment so the non-venomous snakes (the mountain snake, the milk snake, and shovel-nosed snake) have adapted over time to mimic the appearance of the venomous snakes (the coral snake), so that the predators would be confused to which snake is venomous or not. Why do the Sonoran Coral snake, the Sonoran Mountain King snake, the Milk snake, and the Sonoran Shovel-nosed snake look so similar?
