» Life History
The distribution of Arctostaphlyos morroensis is correlated with that of soils developed on ancient sand dunes that were deposited during the Pleistocene (i.e., Baywood fine sands). This species is found in association with coastal dune scrub, maritime chaparral, and coast live oak woodland on sites with low to moderate slopes.
Arctostaphylos morroensis flowers in the winter, with fruit maturation and seed dispersal occurring in the fall. Unlike other species of manzanita, A. morroensis is an obligate seeder, lacking a woody burl from which it can resprout post-fire.
