A high speed Improvised Explosive Device (IED) defeat lane is being constructed along
Chorwan, Wonsan, and Pusan roads during 2009 and 2010. These roadways are traditional travel
and nesting areas for Blanding‟s turtles. The training
activities will significantly increase roadway traffic,
vehicle speeds (maximum of 40 mph), and night maneuver
use particularly during the Blanding‟s turtle nesting season.
During 2009 several Blanding‟s turtles where marked with
reflective tape along the northeast traditional nesting area
(Figures 60 and 61). Blanding‟s turtles were marked to
increase visibility and improve avoidance during IED
defeat lane maneuvers, particularly night maneuvers.
Four Blanding‟s turtles (BDY, BDI, PW, BDJ)
were marked with a 1 x 2 inch self-adhesive, marine safety
reflective tape (3 mil-SOLAS) (Figure 60). This reflective tape is visible with night vision optics.
