Glossary

Chaparral edges are transitional zones where shrublands meet adjacent ecosystems such as grasslands, oak woodlands, or riparian areas. These ecotones often receive more light, moisture, and airflow than interior chaparral, leading to greater plant diversity and structural variation.

In the Santa Cruz Mountains, chaparral edges often support both core species like Chamise (Adenostoma fasciculatum) and Blueblossom (Ceanothus thyrsiflorus), alongside species from neighboring communities such as California Buckwheat (Eriogonum fasciculatum) and Black Sage (Salvia mellifera).

These edge habitats support high biodiversity, providing nectar, shelter, and movement corridors for insects, birds, reptiles, and mammals. They are especially valuable for pollinators, seed-dispersing wildlife, and insectivorous birds that move between habitat types.
