**2. 1. [Background]{.underline}:** (includes short review of geologic
and geomorphic setting of the southern Everglades & a review of previous
geologic studies by others on tree islands in the Everglades National
Park region)

presentation and interpretation of past, published and unpublished, work
and for melding of past and more recent geologic and paleoecologic data
on this subject)
