The Western Riverside County Regional Conservation Authority (RCA) is responsible for managing habitat supporting 146 protected plant and animal species. These species, which are integral to local ecosystems, are at risk due to various factors. To accomplish our goal of protecting these species, the RCA manages more than 45,000 acres of conserved Additional Reserve Land across western Riverside County, providing the best opportunity for these protected species to thrive.

Through a steadfast partnership between RCA and Riverside County Park and Open-Space District (RivCo Parks), the dedicated Riverside County Park rangers and other staff work tirelessly to safeguard conserved lands, ensuring the best possible environment for these protected species.

Some examples of ways lands are managed include combating illegal trash and hazardous materials dumping, interdiction of unauthorized off-highway vehicles (OHV) use, and removing unlawful cannabis grows. To illustrate the scale of the issue, an estimated 16 tons of waste was removed in 2022, a significant increase from the previous years.

Much of the work involved in managing reserve lands is to protect plants and wildlife and limit habitat degradation. This is especially important during critical life cycle stages of certain species, such as the burrowing owl and narrow endemic plant species, which occur during the breeding season and wildflower blooming season.

Aside from just maintaining the land, RCA also enhances habitats. Following heavy rainstorms and fire seasons in 2022, the invasive species, stinknet, was found throughout burn scars and other areas in western Riverside County. Our team methodically pulled, bagged, and disposed of several acres of invasive stinknet plants, effectively restoring these areas, and is conducting active research on developing a selective herbicide application method that targets stinknet but does not inhibit the success of co-occurring native plant species. In 2003, 59 acres of land was successfully restored with coastal sage scrub, providing a thriving habitat for native wildlife.

The public can access RCA conserved lands for passive recreation such as hiking, biking, and birdwatching on existing trails; although, specific properties and trails may be occasionally closed for the public’s safety and to protect sensitive habitats. Thank you for keeping your RCA Reserve lands natural and intact to benefit the 146 animal and plant species protected by the MSHCP.
