Landmarks Focus: Habitat Restoration and Enhancement

Southern California’s urban wildlands are home to thousands of acres of rare and diverse plants and animals found nowhere else on earth. These wildlands are made up of an intricate network of interconnected habitats that over the course of history have faced many threats, and some have become degraded over time as a result. When a habitat becomes degraded, it can affect the health of an entire landscape.
The habitat restoration and enhancement program is the cornerstone of IRC’s conservation work on the Landmarks. IRC staff, volunteers and regional partners work to restore and enhance the ecological health, resilience, and connectivity of these native habitats to support the rare and diverse species that call it home. 

In order to keep these areas thriving, IRC leads long-term, comprehensive ecological restoration efforts using a variety of methods specifically designed to local conditions which work collectively to regenerate the land. In the last 15 years, this IRC program has enhanced or restored over 2,000 acres of land previously degraded by intensive ranching and other land uses.
These efforts are an integral part of the lasting health of the Landmarks. IRC, along with its partners, continue to create innovative solutions to ensure these native habitats are protected for future generations to enjoy.
The Senate recently designated April 2021 as National Native Plant Month, which recognizes the importance of native plants to environmental conservation and restoration, as well as in supporting a diversity of wildlife.
