On April 22, 2009, Omar Bocanegra of the Arlington Field Office celebrated Earth Day with faculty and students of Watauga Elementary School.  Students listened to a presentation on endangered species in the school’s “Outdoor Learning Environment,” which contains a garden, rainfall catchment system, and a small pond.  Over 600 students attended and observed endangered species artifacts and a live lesser siren and gray-banded kingsnake.  The presentation provided an assignment for the third graders, who brought “nature journals” to record information from the event.
