Critical Habitat for Astragalus lentiginosus
« on: February 13, 2013, 03:57:30 am »
Endangered and Threatened Wildlife and Plants; Designation of
Critical Habitat for Astragalus lentiginosus var. coachellae (Coachella
Valley Milk-Vetch)

AGENCY: Fish and Wildlife Service, Interior.

ACTION: Final rule.


SUMMARY: We, the U.S. Fish and Wildlife Service (Service), designate
critical habitat for Astragalus lentiginosus var. coachellae (Coachella
Valley milk-vetch) under the Endangered Species Act of 1973, as
amended. In total, approximately 9,603 acres (3,886 hectares) in the
Coachella Valley area of Riverside County, California, fall within the
boundaries of this critical habitat designation.

DATES: This rule becomes effective on March 15, 2013.

Unauthorized Off-Highway Vehicle (OHV) Impacts

    Unauthorized OHV use may impact Astragalus lentiginosus var.
coachellae habitat by making substrate conditions unsuitable for growth
through the alteration of the sand transport system, changes in plant
community composition, and disruption of the substrate, which can cause
soils to lose moisture and may also impact soil microflora or
microfauna (USFWS 2008, p. 8766). The native plant community associated
with A. l. var. coachellae habitat allows for sand movement and does
not inhibit dispersal. Disturbance from OHV use can affect the plant
composition of the native plant community. Management activities that
could ameliorate the threat of unauthorized OHV use include fencing and
signage of habitat areas to assist in educating the public and engaging
local authorities to improve the enforcement of laws prohibiting OHV
unauthorized use. Control of unauthorized OHV use in habitat occupied
by A. l. var. coachellae has recently improved through the efforts of a
local law enforcement task force in habitat areas including lands
managed by the Bureau of Land Management (BLM) in the Willow Hole
(depositional area in Unit 3) and Snow Creek (depositional area in Unit
1) areas, although OHV use remains on many privately owned lands.
