The National Park Service strives to perpetuate the native animal life of the parks for their essential role in natural ecosystems (National Par Service 1978). In aquatic habitats, the ecological importance of crocodilians is being given increasing recognition by both scientists and wildlife managers (January 10, 1977- 42 FR 2075). This is especially relevant in the Everglades, where the activities of the American alligator (Alligator mississippiensis) are critical to the natural functioning...

In aquatic habitats, the ecological importance of crocodilians is being given increasing recognition by both scientists and wildlife managers (January 10, 1977- 42 FR 2075). This is especially relevant in the Everglades, where the activities of the American alligator (Alligator mississippiensis) are critical to the natural functioning of the ecosystem, serving to maintain species richness and increase habitat diversity (Craighead 1968, Kushlan 1974). In recognition of their important ecological role and their popularity with the visiting public, alligators have become symbols of the wilderness of Everglades National Park.

- Abstract/Description

Wading birds, including ibises, herons, and storks, which once nested in southern Florida by the millions have decreased because of habitat destruction, A 1974-1975 survey located 41 colonies and 129,800 wading birds nesting in southern Florida. White Ibis and Cattle Egret were most abundant, populations of Great Egrets, Little Blue Herons, Louisiana Herons and Snowy Egrets were lower than expected. Wading birds nested year round but individual specie had more circumscribed nesting seasons...

The Wood Stork (Mysteria americana) is a wading bird adapted to fluctuating water levels such as those found in the Everglades of Everglades National Park. The population of Everglades Wood Storks decline through the 1960s and they did not nest successfully from 1967 through 1973. This paper describes a study conducted in 1974 on the factors affecting food supplies and successful nesting of Wood Storks in Everglades National Park.

The population of Everglades Wood Storks decline through the 1960s and they did not nest successfully from 1967 through 1973. This paper describes a study conducted in 1974 on the factors affecting food supplies and successful nesting of Wood Storks in Everglades National Park. Since Wood Storks nested successfully in 1974, this study provided the first opportunity in 7 years to obtain information necessary for the preservation of the species in Everglades National Park. As a result of this initial study , we recommend areas of future research required for proper management of the Everglades ecosystem.

- Abstract/Description
-
The wading birds of south Florida have attracted the attention of naturalists, biologists and conservationists for decades. These species of herons, ibis, spoonbils, and storks have figured importantly in national and international conservation efforts and in the establishment of natural preserves such as Everglades National Park and Corkscrew Swamp Sanctuary. Regional population decreases caused initially by hunting and then by loss of habitat are well known.

Osprey (Pandion haliaetus) populations in various parts of North America decreased during the 1950's and 1960's, primarily because of pesticide contamination, with eastern populations being most affected. The Florida population, considered to be non-migratory, contained low levels of pesticide contaminants. The major cause of localized population decreases that have taken place in the state has been destruction of habitat. This study analyzes the nesting population of osprey in southern...
Show moreOsprey (Pandion haliaetus) populations in various parts of North America decreased during the 1950's and 1960's, primarily because of pesticide contamination, with eastern populations being most affected. The Florida population, considered to be non-migratory, contained low levels of pesticide contaminants. The major cause of localized population decreases that have taken place in the state has been destruction of habitat. This study analyzes the nesting population of osprey in southern Florida during the breeding season of 1978-80 and compares findings to that of an earlier study. The authors conclude that a substantial decrease has occurred in the number of ospreys nesting in Florida Bay. The survey area was divided into three regions: Florida Bay, Whitewater Bay and the Gulf Coast.

The authors outline a recovery plan and recommendations at the end of the report., The Cape Sable sparrow (Ammospiza maritima mirabilis), subspecies of the Seaside Sparrow, restricted to extreme southern Florida, has elicited considerable interest and concern since its discovery in the early 1900's. Before being relegated to subspecific status, it was well known as the last bird species described from the United States (Howell, 1919; Stimson 1968.) It was widely believed to have been exterminated by a hurricane in September, 1935,but discoveries, apparent losses, and subsequent rediscoveries of the bird in various areas repeatedly brought it to public attention and aroused concern for its conservation.

- Abstract/Description
-
Cape Sable, a southwestern projection of the Florida peninsula within Everglades National Park, hosts the southernmost population of the gopher tortoise (Gopherus polyphemus). All suitable habitat of Cape Sable was searched for tortoise burrows; areas where they were found were censured by transect (for several years). Aerial photographs and a map illustrate the study site. The authors discuss environmental variables which impact the tortoise population.

Show moreThe purpose of the present study was to determine the occurrence, distribution, and status of the eastern indigo snake in three National Park Service areas in southern Florida: Everglades National Park, Big Cypress National Preserve, and Biscayne National Park. We did this primarily by analyzing records of sightings in these areas. We also determined the distribution of the indigo snake in the Florida Keys. We include biological information on habitat use, seasonal variation in sightings, food habits, size,parasites, and sex ratio for snakes observed and examined in and adjacent to Everglades National Park.(from "Introduction")., The status and biology of the eastern indigo snake, Drymarchon corais couperi, the largest North American snake (Lawler, 1977), is poorly understood. Destruction of habitat and exploitation by the pet trade have reduced its population levels in various localities to the point that it is listed by the Federal government as a threatened species. Conant (1975) reported its range as southeast Georgia, peninsular Florida, and the lower keys, with disjunct populations in west Florida and southern Alabama. No specimens have been recorded in Alabama since 1954 (Neill, 1954), and it may now be extinct in that state (Mount, 1975). In southern Florida, the indigo snake has been reported to occur in several habitats, including dry Everglades marsh, tropical hammocks, and muckland fields (Carr, 1940).
