Threatened species
A plant or animal that is likely to become endangered if nothing is done to reverse the factors leading to its extinction.

Special concern species
A plant or animal that may become a threatened or an endangered species if current environmental conditions continue.

Why should we care about Species at Risk on Middle Island?

Middle Island is an important resting stopover during bird and butterfly migrations in spring and fall. These birds and butterflies, often called migratory pollinators, need the food and shelter provided on Middle Island to survive their long journey.

Many other species, spread over large areas, depend on migratory pollinators for their own continued health. Protecting the Species at Risk on Middle Island will help maintain biodiversity in our region and preserve an important part of Canada's natural and cultural heritage for future generations.

What is happening to the Species at Risk on Middle Island?

Middle Island has extremely high numbers of nesting double-crested cormorants. These birds physically damage trees through their nesting habits and deposit large amounts of guano on the trees and vegetation below. The nesting habits of this over-abundant nesting colony is destroying Middle Island's ecosystem, making it difficult for the Species at Risk to survive.
