Seed Supply

FGCA and partners are working towards increasing the supply of locally adapted seed of native woody species. Seed supply is essential for forest restoration efforts of all scale. read more...



Butternut is threatened across its range by a canker fungus. The species has all but disappeared in many parts of the U.S.A. and is endangered in Ontario, Quebec, and New Brunswick. read more...


Climate Change

Our forests’ genetic diversity is made of many species, each with many locally adapted populations. Genetic diversity helps keep our forests resilient in the face of climate change. read more...

Native Woody Species Diversity

Ontario has more than 100 woody species. Which ones are native to your area? Find out by using this map to focus in on your area in the North, South, or East parts of southcentral Ontario.

Conserving Genetic Diversity

Did you know...

Within a single species there are additional levels of genetic diversity. Many of our species occur across a large geographic range, thus population diversity or adaptive variation has evolved. This means, for example, that red oak in eastern Ontario evolved to be particularly adapted to those conditions. While in southwestern Ontario, in a different set of conditions the red oak evolved differently.
