The County of San Diego proposes to reduce a threat to the Quino checkerspot butterfly by increasing and improving habitat on a County-owned site that had previously supported a hundred or more butterflies. The Quino is threatened by development pressure, invasion by non-native grasslands (NNG) and forbs, and, likely, changes to climate and long-term drought. It is considered an MSP Category SL (species at risk of loss). The County intends to significantly enhance improve Quino habitat conditions and connectivity by: 1) identifying and closing roads/portions of road on the site to vehicular activity; 2) preventing off-road vehicle activity that may be bifurcating and destroying Quino habitat; 3) fencing and signing these areas to be restored; 4) controlling and removing invasive NNG that compete with plantago erecta, the primary Quino habitat and food source seeding areas with primarily native plant species required for Quino survival; 5) documenting site condition improvements as well as any beneficial effect for Quino,
