Potential for short-term behavioral responses to overflights.<br />

Short-term behavioral responses from general vessel disturbance. Potential for injury or<br />

mortality from vessel collisions because of higher concentration of foraging sea turtles<br />

in coastal waters.<br />

Short-term behavioral responses from landing activity associated with vehicles and<br />

personnel on beaches. Long-term effects of accelerated beach erosion from vehicle<br />

tracks on the beach and craft wakes in the water. Potential for nest failures / nest<br />

mortality for green sea turtles due to possible compaction from vehicles and false<br />

crawls of females attempting to nest due to vehicle landing activity.<br />

All weapons associated with this training activity would occur in confined settings away<br />

from sea turtle nesting areas (e.g. Finegayan Small Arms Range)—no impact.<br />

Potential for ingestion of chaff and/or flare plastic end caps and pistons.<br />

Short-term behavioral responses from general vessel disturbance. Potential for injury or<br />

mortality from vessel collisions because of higher concentration of foraging sea turtles<br />

in coastal waters.<br />
