historical (Simpson 1965). The objectives of this study are to
use an ecological approach that w i l l (1 provide natural history
base1 i ne data upon which further ecological or evolutionary
studies may be based (2) provide a species list of mammals for
habi tat types that are representative of Open Space properties
(3) determine density or relative abundance for each species (4)
provide i nf ormat i on about small mammal popul at i kns i n areas of
special concern (when possible) and (5) conduct visual surveys of
amphibians and reptiles on study areas.
Thi 5 study ori gi naf l y was designed for coll ecting base1 ine
ecological data, and the results must be interpreted as a whole.
Any attempt to interpret results for a specific property or
habi tat-type for 1 and use appl i cat i ons woul d be i.n' inconsistent
with the original design of the study. Data gathered from a
particular property or habitat may be of interest to the
Department, but this study, by its stated objectives, cannot
answer 1 and use questions about speci f i c areas. The most
important value of this study is in defining specific questions
for further study.
