Active Desert Dunes
Background
Description and distribution
Description and distribution. These are essentially barren
expanses of actively moving sand whose size and shape are
determined by abiotic site factors rather than by stabilizing
vegetation. The dunes may intergrade with stabilized and
partially stabilized dunes. This community occurs within a
creosote bush scrub matrix. In the Plan area, these are remnants
of once extensive dunes. Approximately 561 acres still exist in
the Plan area. About 85% of this acreage is currently protected
on the Coachella Valley Fringe-toed Lizard Preserve. The
remainder occurs near Windy Point. For both of the remaining
dune areas, protecting the sand sources and sand transport
systems that sustain the dunes is essential. Additionally, there
is a small patch of active dunes at the east end of the Indio
Hills, west of Dillon Road and north of Interstate 10.
Associated covered species. Covered species associated with this
community are the flat-tailed horned lizard, Le Conte's
thrasher, Coachella giant sand-treader cricket, Coachella Valley
Jerusalem cricket and Coachella Valley milkvetch.
