Summary
Abstract: Wildlife preserves and refuges in coastal areas of our nation are slowly
being inundated by increasing sea level. Warming of our global environment
threatens to speed the rate of sea-level rise and perhaps further amplify the
detrimental effects of tropical storms, droughts, and lightning fires. A
research study was conducted to examine the impacts of tropical storms.
droughts, and lightning fires. A research study was conducted to examine the
impacts of possible cllimate change scenarios on the functional wetland
landbase and habitat of federal parks and refuges along the Gulf of Mexico. In
the Big Bend area of northwest Florida, land elevation and water depth are key
factors controlling habitat type. A digital elevation model of the area was
constructed to track the process and pattern of coastal inundation over space
and time for low, mid, and high sea-level rise projections of the
Intergovermental Panel on Climate Change. The three sea-level scenarios
indicated that major portions of this coastal zone will be permanently
inundated over the next century, bringing about a combined migration and loss
of some habitats. Results show that there is a large land base that will be
quickly converted from coastal salt and freshwater marsh to open water and
coastal pine forest to emergent marsh, approaching the scale of land loss that
has been experienced in south Louisiana, 25-30 square miles per year.

Supplementary Information:
A site application of a GIS-based simulation model, WETLANDS, was developed
to predict ecosystem response to changing environmental conditions for wetland
complexes of the Big Bend region in northwest Florida. The model contains
functional attributes of community sensitivity to hydrologic conditions linked
with a GIS data base of site characteristics, including habitat type,
elevation, soils and land-use. The process of model development requires
multiple data layers of biological and physical descriptions of the landbase
into a geographic information system.

Geographic Description:

The site application includes both the aquatic and terrestrial habitats of
St. Marks National Wildlife Refuge in the Big Bend region of northwest Florida.
The refuge is situated approximately 20 miles south of Tallahassee and covers
parts of Wakulla, Jefferson, and Taylor counties. The total area of federally
owned land incorporates 64,599 acres. Of the total acreage, 31,500 acres are
open water in Apalachee Bay and 32,082 acres are forest and marsh. The refuge
is bordered by Apalachee Bay on the south, Ochlockonee Bay on the west, and
Aucilla River on the east. The reserve was purchased in 1929 and is one of the
oldest refuges in the entire system of the U.S. Fish and Wildlife Service. The
refuge landscape is characterized by a relatively low elevational gradient that
is intersected by several rivers and a number of freshwater springs and
intertidal creeks. 1.5.2 Bounding Rectangle Coordinates

Methodology:

Land elevation and water depth are key factors controlling habitat type and
distribution in this coastal environment. Plot and transect surveys were
conducted to derive a conceptual model of community types and succession under
different environmental conditions and disturbance regimes. First order
benchmarks were used to open and/or close transects across the ecosystem
ecotone in several watersheds within the refuge boundary. Station locations
were established every 30 m along a given transect from which land elevation,
and vegetation cover and stature were recorded. Field data was verified by
constructing histograms of vegetation distribution with surface elevation.


Purpose: To examine the impacts of possible climate change scenarios on the
functional wetland landbase and habitat of federal parks and refuges along the
Gulf of Mexico.
