Woodrats are considered a keystone species: that is, a species upon whom many other species depend. When chaparral stands burn, brush rabbits move in to inhabit the open spaces that are created. The cycle repeats itself as the vegetation grows. Impacts from rampant development along the coast, fire suppression, and vegetation management to reduce fuels in urban and suburban areas have reduced maritime chaparral so significantly that the California Department of Fish and Game now ranks these stands as rare and threatened within California.
As a result, the stand of chaparral in Knowland Park is one of the very few places where people can see this type of vegetation in the East Bay Hills. The aerial gondola would pass directly over the chaparral, and the Interpretive Center would be located at its immediate edge. The best way to find the chaparral in Knowland Park is to enter the park at Snowdown and follow the path to the main fire road that bisects the park from east to west. Head west to the top of the knolls. The chaparral is the dense shrub community to the right north. A good landmark is the cellphone tower located just across the road from the dense chaparral.

Based on the above cited studies, one can summarize the research as follows; attention is focused on simple correlations which should not be used in discussions of causation. Light shade increases seedling survival Williams et al. The elevation and slope may be related to shade density; in addition, s lope and elevation appear correlated—between 2, to 3,, chaparral is denser on north facing slopes while at , foot elevations, chaparral is denser on the east, south, and west facing slopes. Shallow soils have poor drainage; subsurface drainage can be improved with increased organic matter, especially after fires.
The deep rooting pattern in chaparral relates to a Mediterranean climate of wet winters and dry summers and layering is present among certain species i. Greggii can be found in lower layers. Nutrient absorption appears to occur in fine roots at upper levels of soil.
Finally, water-soluble components in the form of terpenes are present in A. Californica , M.
