Marshall, 1942 33. general acct Mt. Cacaguatigre, Dept Morazan, El Salvador Summary I did see some clearing of oaks on a very steep ridge - so will not call this arid brush natural. The natural types are: 1. Large oaks on cool n-e facing slopes, ferns beneath. 2. Denser*, smaller oaks on ridges & e-facing hills with much undergrowth of spindly brushes. 3. Pine & grass on one eastern ridge. This is probably not climax - pines being encroached on by oaks - scattered among oaks except on this one ridge. 4. "arid brush" - ferns & vines & dense brushes & short trees on n-th rim of highest ridge & down into canyon there (see map). 5. (natural?) arid brush on hot south- facing slope - composites, flowers, etc. successional types: to lesser degree in thinned oaks. 1st when oaks cleared - grass & bushes of normal forest floor accentuated. 2nd dense brush, or grass, & vines etc. 3rd small oaks & brush - seen farther down on east ridge & deep canyon below Lacienda.
