relate the presence of an oily film on the water surface to a pesticide incursion into a 
non-target area proved inconclusive. Two filter paper samples of a surface film were 
obtained and neither contained measurable amounts of Naled nor Baytex. The Monroe 
County Mosquito Control District supervises the disposal of used containers at a local 
sanitary landfill which operates a drum crusher. The Safety Director was advised that 
because Naled and Baytex are kept in Group II containers, it is recommended that each 
empty container be triple rinsed and crushed prior to disposal in a landfill.

Centaur Associates, Inc. (1979) Socioeconomic assessment for fishery management, 
Everglades National Park. Rep. T-543. South Florida Research Center, Everglades National 
Park, Homestead, FL. 105 pp. 
[NO COPY OF PAPER AVAILABLE. ABSTRACT FROM SCHMIDT (1991).] This report 
presents the socioeconomic impact assessments and adverse effects from restrictions 
on commercial and recreational fishing activities in the Everglades National Park. The 
Park is unique with respect to fishery resources and fishery management. Florida Bay 
has been subject to a considerable degree of commercial and recreational pressure. The 
issuance of commercial fishing permits are nearly equally divided between Florida Bay 
and the Everglades City area while recreational and guide and charterboat fishing is an 
important attraction primarily in the Flamingo - Florida Bay area. Although all 
commercial and recreational fishing is done in accordance with state regulations, 
intense competition exists between both factions with the result that the NPS explore 
alternative management options for the park's fishery resources. These actions which 
require consideration as they affect three South Florida counties and in relation to 24 
fishery management alternatives, are assessed as follows: prohibition of net fishing, 
bag limits and harvest sizes of major gamefish species, prohibited harvest of stone 
crabs and spiny lobster and commercial permits, boat and motor restrictions, and 
financial and non-financial impacts are given for each management action.

Davies, T. D. (1979) The use of peat petrography in reconstructing shoreline migration in 
the area of Florida Bay. Geol. Soc. Amer. Abs. . 11 (7):410. 
[ABSTRACT ONLY. DATE OF SAMPLING UNKNOWN OR NOT APPLICABLE.] New data 
gathered in Florida Bay substantiates an earlier hypothesis that the sea level rise, to 
its present level, has been continuous during the last 5,500 radiocarbon yrs. It has 
been determined that thirteen peat types occur in Florida Bay ranging from freshwater 
to marine. The non-marine peats are situated at the base of the sediment sequence 
either directly on the Pleistocene bedrock or on a thin layer of freshwater, calcitic 
mud. Radiocarbon dates of the basal freshwater peats from the Bay suggest that 
sedimentation of the freshwater peats took place in the southwestern part of the Bay 
prior to 5,000 yrs BP. This strongly suggests that the position of the shoreline, at this 
time, was a considerable distance to the west and south. The sea probably did not begin 
to influence the vegetation of the Bay area until sometime after 5,000 yrs ago. This is 
particularly well documented by the freshwater tree island peat underlying Ninemile 
Bank dated to be 5190 ± 100 yrs BP. Although these freshwater peats megascopically 
resemble the fibrous coastal, mangrove peats, microscopic examination revealed that 
they are freshwater in origin. Their ’fibrous’ nature results from intruded roots of 
brackish and marine plants which grew in overlying environments. Recognition of this 
fact together with knowledge of the age of the various peat types results in the 
conclusion that the shoreline initiated its migration into the Bay area later than 
previously recognized and its eastern movement has been slower than heretofore 
thought.
