UC Irvine Ecological Preserve Vascular Plant Checklist
Locality: California, Orange County, San Joaquin Hills, UC Irvine: South-west of Aldrich Park, between Michael Drake Drive, East Peltason Drive and Hwy 73 (33.635490, -117.844850)
Abstract:

This checklist is a project of the UC Irvine Herbarium (IRVC). Please contact Collections Manager Rebecca Crowe with questions, rcrowe@uci.edu.

The UCI Ecological Preserve is a 60 acre site on the southern edge of the campus located adjacent University Hills, the Irvine Research Park, and the San Joaquin Transportation Corridor. The reserve straddles a the ridge of a large hill, with several canyons and lower ridges radiating west from the main spine which runs north-south.

For each plant we list observed habitat, habit, and orign. Habitats include: Coastal sage scrub (CSS), wetland mitigation area (W), created
vernal pools (VP), grassland (G), and ruderal (R). Habits include: 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PERSISTING FROM CULTIVATION: originally planted/cultivated, but no longer maintained; not reproducing or escaping into native habitats;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.

Notes: This checklist updates taxonomy and builds on the Bowler and Bramlet 2002 checklist and the unpublished 2010 updated checklist by the same authors. Bowler, P.A. and D. Bramlet. 2002 (issued August, 2003). Vascular plants of the University of California, Irvine Ecological Preserve. Crossosoma 28(2): 27-49.
