The <strong>Base</strong> is in consultation with USFWS regarding monitoring and management of upland<br />
habitats and species basewide including vernal pools/IEWs occupied by the San Diego<br />
button-celery. The <strong>Base</strong> has instituted measures for avoidance and minimization of impacts<br />
to vernal pools, IEWs and all vernal pools species including the San Diego button-celery.<br />
These measures are published as programmatic instructions for users and residents of the<br />
<strong>Base</strong> via <strong>Camp</strong> <strong>Pendleton</strong>’s <strong>Base</strong> Order P3500.1M (Range and Training Regulations).<br />
