In 2018, Preserve Calavera and Friends of El Corazon began a long-term effort to remove invasive fennel from the hillsides of the El Corazon Nature Park. Monthly events continue at this site, which include fennel seed removal and cutting/stacking of the fennel plants. The removal of invasive plants allows the habitat to remain healthy to support sensitive wildlife like the Coastal California Gnatcatcher and Least Bell’s Vireo. This site is also known as Garrison Creek which is part of the Loma Alta Creek watershed that ultimately flows into the Pacific Ocean. Keeping our watersheds healthy benefits all of us.
Fennel is a perennial herb that was introduced to California from southern Europe in the 1800s. Fennel can outcompete native species and it is difficult to control because of its prolific seed production and seed viability. Fennel will invade areas where the soil has been disturbed and can exclude or prevent reestablishment of native plant species. It can drastically alter the composition and structure of many plant communities, including grasslands, coastal scrub, riparian, and wetland communities.
If you would like to join our efforts to slay the mighty fennel, check our activities calendar for our monthly event at this site.
