a species on which other species in an ecosystem largely depend, such that if it were removed the ecosystem would change drastically.

At Keystone Acres we work to grow the best produce with no chemicals or sprays. In addition to growing food, we dedicate half of our land to rewilding through planting of native species, with special consideration given to keystone species

Welcome to Keystone Acres! We are a small farm located in Sheffield, Ontario. Our goal is to provide high quality, local produce while returning land to its natural state.

We are currently closed for the winter season but looking forward to a productive 2026. Our farm stand will be opening in early July!
