HABITAT TYPES AND PLANT COMMUNITIES : 
California buckeye woodland is recognized as a distinct plant community
[13].  The species may also codominate oak (Quercus spp.) woodland.
Interior live oak (Q. wislizenii) and blue oak (Q. douglasii) are the
most common codominants of oak woodland [1,2,3,22,23].  In chaparral, it
is sometimes a dominant shrub or tree [2,4].
