Alternative Text Description for Southern Sandshell (Threatened)

TABLE OF CONTENTS

MAP OVERVIEW

This map displays the geographic range of the Southern Sandshell, a threatened species, across the Florida Panhandle region. The map shows polygonal boundaries representing areas where this species is documented, as understood by the United States Fish and Wildlife Service. The pink hatched pattern identifies the extent of the Southern Sandshell's habitat distribution within the state.

GEOGRAPHIC CONTEXT

The map covers the western Florida Panhandle region, extending from the Alabama border on the west to areas east of Enterprise, and from north of Andalusia southward to the Gulf of America coastline. Major communities visible on the map include Panama City and Lynn Haven along the coast, Pensacola and Brent in the western portion, Crestview in the central area, and smaller communities such as Monroeville, Troy, Enterprise, Dothan, Ferry Pass, and Bankhead Lake. The southern portion of the map shows the Gulf of America coastline and coastal barrier islands.

KEY INSIGHTS

The Southern Sandshell's range forms a broad horizontal band across the central and western Florida Panhandle. The distribution extends continuously from west to east across much of the mapped area, situated between the northern inland communities and the Gulf of America coast. The species' habitat appears concentrated in the middle elevations of the region, generally positioned north of the immediate coastal zone but south of the northernmost communities. A notable gap in the distribution occurs around Crestview, where the habitat area narrows significantly before expanding again to the east and west.

VISUAL ELEMENTS

Southern Sandshell (Threatened) Distribution

Brief description: This layer represents the documented geographic range of the Southern Sandshell, a threatened species tracked by the United States Fish and Wildlife Service.

Southern Sandshell Range Areas (pink diagonal hatching pattern)

Appearance: Pink or light red diagonal hatching pattern filling polygonal areas, creating a crosshatch texture that distinguishes habitat zones from the base map.

Distribution: The range extends across the central portion of the Florida Panhandle in a generally east-west orientation. The distribution encompasses areas roughly 40 to 80 miles inland from the Gulf of America coast, spanning from the western edge of the mapped area near the Alabama border eastward past Enterprise.

Notable locations: The habitat zone passes through or near Crestview in the central portion of the map. The distribution extends southward closer to the coast in the western portion near Pensacola and Brent, while maintaining a more inland position in the eastern portions. The range reaches its southernmost extent in areas north of Panama City and Lynn Haven.

Spatial patterns: The distribution forms a relatively continuous belt across the mapped region with irregular northern and southern boundaries. The habitat shows constriction in the Crestview area, creating a narrower corridor before widening again to the east and west. The southern boundary of the range generally follows a pattern that maintains distance from the immediate coastal zone and barrier islands, suggesting the species occupies inland aquatic habitats rather than coastal waters.

Overlapping Patterns

The Southern Sandshell range overlays a base map showing municipal boundaries, roads, and water features. The species' distribution appears to correlate with inland water systems rather than following political boundaries or transportation corridors.

SYMBOL GUIDE

ADDITIONAL INFORMATION

This map represents a single thematic layer extracted from a larger dataset maintained by the United States Fish and Wildlife Service. The focus is on the spatial distribution of a specific threatened species rather than comprehensive ecological or environmental context. The Southern Sandshell range shown reflects current understanding of the species' geographic extent within Florida. The map scale and detail level are appropriate for regional planning and conservation assessment purposes. Features such as roads, municipal boundaries, and geographic labels are included for geographic reference but are not the primary thematic content.

DATA CONTEXT

Data Source: United States Fish and Wildlife Service species boundary data for the State of Florida. The dataset contains polygonal boundaries for species as understood by the USFWS.

Definition Query: This map displays a filtered subset of the complete USFWS species dataset. The definition query parameter "COMNAME = 'SOUTHERN SANDSHELL'" was applied to display only the Southern Sandshell species from the broader CR_USFWS_POLY_JUN26 dataset.

Scale Information: The map scale is appropriate for regional-level analysis spanning multiple counties across the Florida Panhandle. The level of detail shows major communities and geographic features while depicting the species range as continuous polygons rather than site-specific point locations.

Coordinate System: NAD 1983 HARN Florida GDL Albers (WKID 3087), a projected coordinate system optimized for mapping the state of Florida with minimal distortion.

Limitations: The boundaries shown represent the understood range of the species and may not indicate actual population density, habitat quality, or presence at every location within the polygons. Areas outside the mapped range do not necessarily indicate absence of the species, as the data reflects current documented understanding by the USFWS. The map shows only the Southern Sandshell and does not depict other species or ecological factors that may influence habitat suitability.

Map Coverage: The map extent covers the western and central Florida Panhandle from the Alabama border eastward to the Dothan/Enterprise area, and from northern inland areas southward to include the Gulf of America coastline and Panama City area. Some context areas outside Florida, including portions of southern Alabama, are visible for geographic reference.
