. The ecological impact of man on the south Florida herpetofauna. Amphibians -- Ecology Florida; Nature -- Effect of human beings on Florida. SPECIAL PUBLICATION-MUSEUM OF NATURAL HISTORY. Fici Kh 33. Rock\ canal dike in webiern Uade County commonly inhabited by Elaphe guttata as well as other snakes. In recent years extensive portions of such dikes have been hauled away for use in constructing roadbeds and housing founda- tions. (LP) sleepy little towns, which comprised the urban areas of southeastern Florida in the 1940's and 1950's, deserved a better fate than the development that overtook them in the 1960's and then exploded completely out of hand in the 1970's. Their sad fate is one that will be duplicated anywhere that undisciplined and unlimited growth is allowed to occur. We must learn these lessons. Our concern for these problems has resulted in part from our interest in assessing man's impact on the area's native amphibians and reptiles. From the data we have presented, it is obvious that the major factors acting to reduce native amphibian and reptile populations are destruction of natural cover and manipulation of the hydrologic cycle. This statement cannot be too strongly empha- sized. Additional pressures on the indigenous herpetofauna exist, but their importance is insignificant when compared with the two major sources of environmental pressure. The additional pressures, listed in what we believe to be their decreasing order of importance, in- clude: (1) destruction of man-made cover; (2) naturalization and spread of injurious exotic plants; (3) vehicular traffic; (4) biocides and other forms of pollution; (5) man-generated fires; (6) outright killing; (7) collecting; and (8) competition with exotic amphibians and Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original Wilson, La
