Wildlife trail cameras throughout the Martin Griffin Preserve offer a glimpse into the lives of the wildlife that call the preserve home.

Great Egret

Though ACR continues closure of Martin Griffin Preserve’s Picher Canyon during the 2015 nesting season, ACR staff continues to monitor nests and conduct education programs.
