Why Are Oaks Disappearing?

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

You can view some of what has been lost on our Lost Oaks page. 

The video below shows how the loss of habitat has threatened Oregon’s Garry oak, known in Oregon by the name White oak.
