UC Irvine Reserves

The climate at Burns, intermediate between the mountains to the west and the desert to the east, accommodates upland plants tolerant of drought as well as desert plants tolerant of low temperatures.
The Mojave desert supports abundant annuals, which produce a spectacular spring show of wildflowers. In wet years, the reserve's slopes are dominated by flowering purple phacelia (Phacelia purpusii) and desert mallows (Sphaeralcea ambigua). Parish's daisy (Erigeron parishii) - a species federally listed as threatened - can be found at Burns.
A wide variety of plant-growth forms occur on this desert reserve. Notably, the flora here includes several species of desert ferns, mosses, and parasitic plants. Three species of mistletoe grow on site; most conspicuous is the juniper mistletoe (Phoradendron juniperinum), which forms large, rounded masses in its host tree. California cloak fern (Notholaena californica) and bird's-foot fern (Pellaea mucronata) may be found growing in rock crevices practically anywhere on site. Mosses are most abundant in lower Railroad Canyon. Cacti and succulents occur throughout the reserve.
