Permanent Conservation

The Western Riverside County Regional Conservation Authority was created in 2004 to implement the Multiple Species Habitat Conservation Plan (MSHCP). One of the MSHCP requirements is to form a 500,000-acre habitat reserve for the native animal and plant species in the region. Through careful and deliberate land acquisition, the RCA is on track to meet its conservation goal.

Species Protection

The MSHCP monitors habitat loss and welfare of protected species while managing the conserved lands to help animals and plants thrive.

Streamlining Infrastructure Improvements

The MSHCP streamlines infrastructure and development, which leads to cost savings and improved efficiency.
