To the east of the Finca and also to the west there are rather dense stands of oak trees which are covered with moss + epiphytes -sheerly covered. The oak forest is not extensive in distribution, however - probably only 2 or 3 sq. miles of it in the immediate region. I could see no particular reason why some slopes are covered with this oak forest while others only a short distance away, and at the same elevation, are grown to the evergreen forest until no oaks present. Oaks are about 10-25 feet high - mostly rather small. Much more heavily covered with epiphyte, than were the few oaks seen near Santa Rita - good solid forest of nothing but oaks. -- The region around San Pedro is rather more level than that at Santa Rita - more rolling hills rather then so many steep slopes.
