Safeguard Thickson’s Woods and Protect Precious Habitats!

Thickson's Woods Nature Reserve

About

Right now, we have an amazing opportunity to safeguard a biodiverse, transit-accessible and urban nature reserve at Thickson’s Woods in Whitby—and protect this treasured property forever!

Thickson’s Woods is a rare gem: a migratory bird stopover and beloved urban green space. Land like this is exceedingly scarce and nearly impossible to find anywhere else in the Greater Toronto Area.

Vulnerable Habitat

This 10-hectare birding hotspot is an oasis packed with biodiversity, supporting 75 rare and at-risk species, and is the last remnant of old-growth white pines on the north shore of Lake Ontario. It consists of rich and diverse habitats including mixed forest, open meadow, a provincially significant wetland and 400 metres of Lake Ontario shoreline.

It’s a vital ecological corridor that needs permanent protection and dedicated stewardship, after being safeguarded by Thickson’s Woods Land Trust for decades. Ontario Nature is grateful to Thickson’s Woods Land Trust for this gift of land. Now we need to do our part to manage and steward the land.

“Through the years, birds and birders keep coming to this migration hotspot on both the St. Lawrence and Mississippi River flyways. Current checklist of birds is 329 species, not bad for 25 acres of white pines and meadow!” — Margaret Carney, Thickson’s Woods Land Trust

Protect Your Share

Not only will your gift help safeguard Thickson’s Woods in perpetuity, but it will also help with vital and ongoing research, monitoring, stewardship and other on-the-ground conservation projects.

We’ve already identified another remarkable property to acquire, an 18-acre parcel adjacent to our Lost Bay Nature Reserve in the globally significant Frontenac Arch. This land supports 33 rare and at-risk species including cerulean warbler, Blanding’s turtle, butternut and eastern whip-poor-will, and is at risk of being lost if we can’t act quickly. Opportunities like this are rare and time sensitive. Your support of Ontario Nature provides the funds to take urgent action when conservation opportunities like this arise.
