This is a checklist of the native and naturalized vascular plants occurring on the University of California Natural Reserve System's Burns Piñon Ridge Reserve (BPRR) in Pioneertown, California. This checklist is an update of the working list, A Checklist of the Vascular Plants at the University of California Natural Reserve System’s Burns Pinyon Ridge Reserve by Mark A. Elvin, Peter A. Bowler, & Andrew C. Sanders (2006).
This checklist lists all known vascular plants documented in Elvin et al (2006) and herbarium specimen vouchers, which are linked to the Consortium of California Herbaria cch2.org. For each plant, we list duration and origin. Plant duration includes annual, biennial, and perennial. Plant origins we define as:
NATIVE: thought to occur naturally in the area, not human introduced;
NATURALIZED: not native but successfully reproducing and spreading in native habitats without human intervention;
PERSISTING FROM CULTIVATION: originally planted/cultivated, but no longer maintained; not reproducing or escaping into native habitats;
WAIF: not native to the area, having been (unintentionally) human introduced, escaped from cultivation, or naturally dispersed into a natural habitat, but currently not or sparingly reproducing/spreading past initial generation or establishment. Some potential to become naturalized.
