Los Guilicos Ecological Reserve
Map SatelliteThis reserve is located on the lower slopes of Mount Hood in Sonoma Valley. Most of the area is covered by a mixed evergreen forest with Douglas fir, Pseudotsuga menziesii, the dominant tree mixed with black oak, Quercus kelloggii, and madrone, Arbutus menziesii. Arctostaphylos manzanita is prominent in the understory.
There is a small oak woodland in the higher elevation consisting primarily of white oak, Quercus garryana, with some coast live oak, Quercus agrifolia. The understory is grassland and, during the spring, supports a fine display of wildflowers.
A portion of the area, on the valley floor, was farmed but now is in a successional stage to a Douglas fir forest.
Animals are typical of the area.
There are important archaeological finds on the reserve.
Integrity: The area has been farmed and grazed, but much of the vegetation on the slopes is virtually undisturbed.
Use: Research, educational.
