Research Natural Areas<br />
Established<br />
American Canyon 1,529 acres Places: Avenales<br />
The 1,529-acre American Canyon Research Natural Area is located within the Machesna<br />
Mountain Wilderness on the Santa Lucia Ranger District. Coulter pine occurs in abundance<br />
here<br />
as dispersed, generally even-aged stands of varying size and density. Fires swept through the<br />
southeast and northwest portions of the basin in 1921 and 1939 respectively. Most of the stands<br />
date back to those fires; however, ridgetop and canyon bottom stands spared from the fires<br />
contain older trees. The associated chaparral is dominated by chamise and Eastwood manzanita.<br />
An approved off-road vehicle trail runs along<br />
the east-west ridge of the basin. Other recreation<br />
use in the area consists<br />
mostly of hunting.<br />
Black Butte 940 acres Places: Cuesta<br />
This 940-acre RNA is situated on the steep, generally northwest-facing slopes of Cuesta Ridge in<br />
the Santa Lucia Wilderness. Knobcone pine-chaparral is the target vegetation type and is found<br />
on north and northeast slopes as scattered groves and occasional continuous areas. Chaparral<br />
species, principally chamise, manzanita, and the sensitive Santa Lucia manzanita occupy the<br />
areas between pine stands. The intermittant streams that drain into the Black Butte RNA support<br />
riparian vegetation composed of coast live oak, California bay, tanoak, and bigleaf maple. There<br />
are no trails located within the RNA.<br />
San Emigdio Mesa 1,239 acres Places: Mt. Pinos<br />
The San Emigdio RNA encompasses 1,239 acres of a large alluvial fan, dissected by several<br />
intermittent stream channels and gullies on the Mt. Pinos Ranger District. The target vegetation<br />
type is pinyon-juniper woodland. Pinyon pine (the dominant tree species) averages 15 to 20 feet<br />
in height and is evenly distributed over the entire area in low to moderate densities. Of the three<br />
common brush species (California juniper, big sagebrush, and dwarf oak), dwarf oak is by the far<br />
the most abundant. Some hunting may occur in the area, but there are no hiking or off-road<br />
vehicle trails through the RNA.<br />
Cone Peak Gradient 2,734 acres Places: Big Sur<br />
The Cone Peak Gradient RNA (a 2,734-acre area) is remarkable for its ecological diversity.<br />
Within a three-mile horizontal distance inland from the Monterey coast, the mountains rise from<br />
sea level to 5,000 feet. The resulting elevational and climatic gradient has 12 plant communities<br />
including canyon live oak woodland, mixed evergreen forest, coast live oak woodland, coast<br />
redwood and chaparral. The RNA lies within the Ventana Wilderness, and several trails traverse<br />
the area.<br />
