For Training Class trainees only:   Bring your "Common Native Trees" book (with the "key" at the beginning).  And binoculars (optional) and your loupe can be helpful for getting a closer look at details, if you wish.   We will take a walk at Bon Air Park in Arlington with Urban Forest Manager Vincent Verweij to practice Tree ID skills.  Will be mostly on paved paths and grassy areas, but wear long pants and sturdy shoes in case we step off trail at times.   Gather in the parking lot of Bon Air Park (at the far end) at 850 N Lexington St, Arlington, VA 22205.  If you can't find us, call Noreen at 703-624-8342.
