The Naval Facilities Engineering Command Southwest (NAVFAC SW) has awarded a task order to the GeomorphIS/Apex team to provide habitat protection, maintenance and enhancement for the endangered California least tern (Sternula antillarum browni) (LETE) and threatened western snowy plover (Charadrius nivosus nivosus) at designated tern colony sites on Marine Corps Base, Camp Pendleton (MCBCP) during 2017-2018. This project will improve the nesting habitat within the LETE colonies through fence construction and maintenance. Habitat within the LETE colonies varies annually and is dependent upon natural processes and anthropogenic disturbances.
