The Garry oak, along with many other oak species, thrive in the prairie oak habitat. Due to development, economic activity, the growth of invasive species such as ivy, and constantly advancing conifer trees, as much as 99% of the native prairie oak ecosystem has been lost. Without a suitable habitat, Garry oaks have vanished from our landscapes.
