Species at Risk Public Registry

2020-7-7 · Visitor numbers are lower at NCC properties on Pelee Island, paths are wider and few snails were observed on trails during fieldwork in 2013-2015. Hunting is allowed on all NCC properties and trampling of snails and their habitat by hunters is possible. Due to lower snail densities in these properties, the likelihood of crushing snails is lower.
