San Dimas Experimental Forest, California—a giant outdoor hydrologic labThis article is part of a larger document. View the larger document here.
A visitor to the San Dimas Experimental Forest might be forgiven for wondering where the trees are. It’s not that San Dimas doesn’t have trees; the native chaparral that furs the canyonsides has a lot of scrub oak—technically a tree—amid chamise, ceanothus, and toyon. Moister riparian grottos support laurel, sycamore, and alder. And clinging to the edges of roads are a few specimens of incense-cedar and Coulter pine, exotics brought in by early foresters.
