Alternative Text Description for Southern Elktoe (Proposed Endangered)

TABLE OF CONTENTS

MAP OVERVIEW

This map displays the geographic range boundary for the Southern Elktoe, a freshwater mussel species proposed for listing as endangered under federal regulations. The map shows a single continuous polygonal area representing the species' known habitat and distribution as defined by the United States Fish and Wildlife Service. The shaded region indicates where this aquatic species is understood to occur within the state of Florida and extends into adjacent areas of neighboring states.

GEOGRAPHIC CONTEXT

The mapped area covers portions of northwest Florida and extends into southeastern Alabama and southwestern Georgia. Major cities within or near the boundary include Marianna, Alford, Clarksville, Blountstown, and Sneads in Florida. The boundary encompasses portions of Jackson, Calhoun, Liberty, and Gulf counties in Florida. Notable features within the region include the Apalachicola National Forest and the Chipola River Wildlife Management Area. The mapped extent reaches westward toward Dothan, Alabama, and extends north toward Bainbridge, Georgia, providing context for the species' range beyond Florida's borders.

KEY INSIGHTS

The Southern Elktoe's range forms a large, irregularly-shaped contiguous area concentrated in the Florida Panhandle region. The distribution suggests a strong association with river systems and watersheds in this area, likely following the drainage patterns of the Apalachicola-Chattahoochee-Flint river basin. The range exhibits a north-south orientation with the widest extent in the northern portion near the Florida-Alabama-Georgia border, tapering somewhat as it extends southward. The continuous nature of the boundary indicates connected aquatic habitat throughout this region, though the species' actual occurrence within this boundary may be limited to specific stream and river segments suitable for freshwater mussel habitat.

VISUAL ELEMENTS

Southern Elktoe (Proposed Endangered)

The map displays a single thematic layer representing the species boundary for the Southern Elktoe.

Species Range Boundary (pink crosshatch pattern)

Appearance:

The boundary is depicted with a pink crosshatch or diagonal line pattern filling the entire polygonal area, creating a semi-transparent overlay that allows base map features to remain visible beneath.

Distribution:

The boundary extends across multiple counties in northwest Florida, with the primary concentration in the Panhandle region. The area spans from near the Gulf of America coastline northward to the Alabama and Georgia state lines.

Notable locations:

Major population centers within or adjacent to the boundary include Marianna, which appears centrally located within the range, and Blountstown in the southern portion. The Apalachicola National Forest occupies a significant portion of the southern extent of the mapped area.

Spatial patterns:

The boundary follows an irregular, organic shape that suggests alignment with natural watershed boundaries and river systems rather than political or administrative boundaries. The northern portion of the range is broader and more expansive, while the southern extent narrows as it approaches the Gulf coastal region. The western edge shows irregular protrusions and indentations, likely corresponding to tributary systems and topographic features that influence aquatic habitat connectivity.

SYMBOL GUIDE

ADDITIONAL INFORMATION

This map represents a species range boundary rather than individual occurrence points, meaning the shaded area indicates the general geographic extent where the Southern Elktoe is understood to occur according to federal wildlife management data. The actual distribution of the species within this boundary is likely limited to suitable freshwater mussel habitat within rivers and streams. As a freshwater mussel species, the Southern Elktoe requires flowing water with appropriate substrate conditions, water quality, and host fish species for its larval stage. The proposed endangered status indicates that this species faces significant conservation concerns and is under consideration for federal protection. Users should note that this map shows the species boundary as defined for the State of Florida context, though the range extends into adjacent states.

DATA CONTEXT

Data Source:

United States Fish and Wildlife Service species boundary data for the State of Florida. The data represents polygonal boundaries for species as understood and defined by federal wildlife management authorities for conservation and regulatory purposes.

Definition Query:

The map displays only records where the common name equals "Southern Elktoe" from the broader species boundary dataset (CR_USFWS_POLY_JUN26), filtering to show this single species from the complete collection of species boundaries maintained by the agency.

Scale Information:

The map displays a regional view appropriate for understanding the overall geographic extent of the species range across multiple counties and portions of three states. This scale is suitable for conservation planning, regulatory decision-making, and general understanding of the species' distribution, but may not reveal fine-scale habitat details or site-specific occurrence information.

Coordinate System:

NAD 1983 HARN Florida GDL Albers (WKID 3087), a projected coordinate system optimized for accurate area measurements and spatial analysis within Florida.

Limitations:

The boundary represents the understood geographic range of the species but does not indicate actual presence or absence at specific locations within the boundary. Freshwater mussels have specific habitat requirements, and suitable habitat within this boundary may be limited to particular stream reaches, river segments, and substrate conditions. The data reflects species understanding as defined by federal wildlife authorities and may be subject to revision as new survey data, taxonomic information, or ecological research becomes available.

Map Coverage:

The map extent covers northwest Florida and portions of southeastern Alabama and southwestern Georgia, with the primary focus on the Florida Panhandle region. The mapped area extends from approximately the Gulf coastal region northward to the tri-state border area, and from near the Apalachicola River system westward into Alabama.
