Evey Canyon This is a steep-sided, east-west trending canyon near
the base of the San Gabriel Mountains. The
upper slopes are covered by chaparral with chamise, Adenostoma fasciculatum,
dominant and Ceanothus sp. and Arctostaphylos sp. present.
On the lower slopes, coast live oak, Quercus agrifolia, is the main
component of the oak woodland. Grading upward into the woodland from the canyon floor,
where there is a perennial stream, is a particularly well-developed riparian
association. Among the species present are sycamore, Platanus racemosa, willow,
Salix lasiolepis, white alder, Alnus rhombifolia, California bay, Umbellularia
californica, and big-leaf maple, Acer macrophyllum. A few stands of big-cone
Douglas fir, Pseudotsuga macrocarpa, occur on the north-facing slopes.
Several of these species are uncommon at this relatively low elevation. The animal populations include a variety of species,
some of which are more commonly associated with the higher elevations such as
Steller's jay, Cyanocitta stelleri, mountain chickadee, Parus
gambeli, and
varied thrush, Ixoreus naevius. At
least 75 species of birds, 16 mammals and 10 reptiles have been observed in the
canyon. Of note are the breeding
spotted owls, Strix occidentalis. Ringtails,
Bassariscus astutus may be present. Integrity: Aside
from a fire road and some use adjacent to the highway bordering the mouth of the
canyon, Use: Research, education. May 1982
