Center Info

Additional details about the Center.


While education and outreach continue to be the Center’s primary focus, the need for research has increased significantly because of the increase in Program funding in 2014.  You can review past and current research projects at the link above.


Over the past several years, the Center has been getting more involved in Environmentally Sensitive Trail Maintenance. Many of the Centers strategies and practices developed for unpaved roads can be adapted for use on trails. This includes the "Trail Surface Aggregate" (TSA) which is a more durable aggregate used for surfacing trails.
