![]() ![]() In order to prevent this disease and others from spreading, people should not handle herptiles. More research is needed to learn more about SFD in Ontario, and projects such as NCC’s queen snake surveys will provide more information about the disease’s distribution and its impact on individuals and larger populations. However, there are now confirmed cases of the disease in Ontario, including a queen snake on the Saugeen Bruce Peninsula that tested positive for the presence of the disease. SFD was first reported in New Hampshire, and is most prevalent in the eastern United States. SFD is a debilitating skin disease syndrome that affects several snake species across eastern North America. Little is known about the disease, or its potential impact on snake populations, its distribution and even its origin. In addition to the above threats, snake fungal disease (SFD) is an emerging threat to snake species across Canada. As these snakes are often found along river and lake edges under rocks, snakes may be crushed by vehicles or pedestrians. They are very sensitive to environmental contamination, as are populations of crayfish, which the queen snake relies on. Wetland drainage, forest clearing and an ever-increasing human footprint threaten many snakes across the province, especially queen snake. Unfortunately, there are many threats to Ontario’s herptiles. Whether it be through directly protecting land where these species are found, completing restoration work in suitable habitat (such as invasive species management or habitat creation) or gathering information about habitats that these snakes use, to help identify new populations, all of the information collected is valuable to their protection. Gathering more information about these populations and their distributions can help conservation organizations such as NCC work to protect species. We employ rigorous sterile techniques, and only handle animals when absolutely necessary. These permits allow us to carefully handle species in order to collect important data about health, diet and population dynamics. NCC’s queen snake project has multiple permits to complete these project, such as Animal Care Permits and Wildlife Science Collectors Authorization, among others. During the surveys, more than 250 snakes from eight different species were identified, as well as a new observation of a four-toed salamander in the survey area.Įsme Batten, NCC’s coordinator, conservation biology for the Saugeen Bruce Peninsula, holds a young queen snake. This was more than had ever been recorded in the area. This year, NCC staff and volunteers were lucky enough to spot 17 queen snakes throughout the surveys. NCC and others organizations across Ontario have been trying to find out more about these snakes, as much remains unknown. Interestingly, their diet consists almost exclusively of freshly molted crayfish. However, they’re most often found under rocks. These snakes are very aquatic, swimming and basking in open water and in shrubs along the edge of the water. Queen snakes are dark brown with a distinctive yellow belly and four dark stripes running along the sides of their bodies. There’s only one known population of queen snake on the Peninsula, and unlike other populations in Ontario found commonly along rivers, these are found in lakes. These cryptic snakes are not easy to find.

In Ontario there are 55 herptiles, including 18 snake species. This summer, NCC staff completed several surveys for herptile species at risk on the Saugeen Bruce Peninsula, in Ontario, including queen snake and massasauga rattlesnake. ![]() You never know what you might find when you carefully look under a rock or a log, or what plants you may find or birds you’ll hear when you walk in a forest, or what herptiles (reptiles and amphibians) you might stumble across. I often think of being a conservation biologist as like being a treasure hunter. ![]() ![]() It was the first day of our annual queen snake surveys, and we were all curious about what we might find. Paddling across the lake, fellow staff from the Nature Conservancy of Canada (NCC) and I couldn’t contain our excitement. When these snakes are observed, not only do we look for signs of snake fungal disease, we also examine them for signs of injury and measure them so we can better understand the number of young versus adults in the population.
