Alternative Text Description for Round Ebonyshell (Endangered)

TABLE OF CONTENTS

MAP OVERVIEW

This map displays the geographic range of the Round Ebonyshell, an endangered species, across the southeastern United States. The map shows the known habitat boundaries for this species as designated by the United States Fish and Wildlife Service. The distribution pattern reveals the limited geographic extent where this endangered species occurs, emphasizing its restricted range and conservation status.

GEOGRAPHIC CONTEXT

The map covers portions of the southeastern United States, primarily focusing on Georgia, South Carolina, and Florida. Major cities labeled include Atlanta (partially visible on western edge), Athens, Greenville, Columbia, Charleston, Wilmington, and Jacksonville in the northern portion. In Florida, cities shown include Jacksonville, Gainesville, Orlando, Tampa, St. Petersburg, Lakeland, Palm Bay, West Palm Beach, Port St. Lucie, Fort Myers (implied by location), Cape Coral, Coral Springs, and Freeport. The map also shows portions of Albany, Macon, Warner Robins, Augusta, Savannah, Valdosta, Tallahassee, and Palm Coast. The Atlantic Ocean is visible along the eastern edge, and the Gulf of America is visible along the western edge of Florida.

KEY INSIGHTS

The Round Ebonyshell exhibits an extremely limited and fragmented distribution pattern. The species' range is concentrated in two primary areas: a linear corridor running through central Georgia and South Carolina, and isolated patches in northern and central Florida. The most significant concentration appears along what is likely a river system corridor extending from central Georgia through South Carolina toward the coast near Charleston. Secondary occurrences are scattered in northern Florida near Jacksonville and in central Florida near the Orlando area. The highly restricted and fragmented nature of this distribution underscores the endangered status of this species, showing it occupies only small, isolated habitat patches rather than a continuous range.

VISUAL ELEMENTS

Round Ebonyshell (Endangered)

This layer represents the geographic boundaries of confirmed habitat areas for the Round Ebonyshell, an endangered species tracked by the U.S. Fish and Wildlife Service.

Round Ebonyshell Habitat Areas (light pink/rose with diagonal line pattern)

Appearance:

The habitat areas are shown as light pink or rose-colored polygons filled with a diagonal line hatching pattern, creating a distinctive crosshatch texture.

Distribution:

The habitat areas appear in two distinct geographic regions. The primary concentration forms a linear corridor through central Georgia and South Carolina. Secondary occurrences are located in northern Florida near Jacksonville and in central Florida in the Orlando vicinity.

Notable locations:

The most prominent habitat corridor extends through central Georgia, passing through or near the region between Macon and Augusta, continuing northeastward into South Carolina toward Charleston. In Florida, smaller isolated patches appear near Jacksonville in the north and near Orlando in the central portion of the state.

Spatial patterns:

The distribution shows a strongly linear pattern in Georgia and South Carolina, suggesting association with a river system or watershed. The Florida occurrences are isolated and disconnected from the main population area, indicating habitat fragmentation. The overall pattern demonstrates a highly restricted range with significant gaps between occupied areas, consistent with an endangered species experiencing habitat loss or limitation.

Overlapping Patterns

No overlapping patterns are visible in this single-layer thematic map.

SYMBOL GUIDE

ADDITIONAL INFORMATION

This map represents a single thematic layer extracted from the U.S. Fish and Wildlife Service species database for Florida. The map focuses specifically on the Round Ebonyshell, an endangered mollusk species. The visible boundaries represent officially designated habitat areas based on scientific surveys and species occurrence data. The base map provides geographic context through city labels and state boundaries but is not the primary focus of this conservation-oriented map. Users should note that absence of shading does not necessarily indicate the species has never occurred in an area, but rather represents areas where current documented habitat boundaries have not been established by the U.S. Fish and Wildlife Service.

DATA CONTEXT

Data Source:

The data source is the United States Fish and Wildlife Service species boundary dataset for the State of Florida. This dataset contains polygonal boundaries for species as understood and documented by the U.S. Fish and Wildlife Service. The source layer is CR_USFWS_POLY_JUL25.

Definition Query:

This map displays a filtered subset of the complete species dataset. The definition query limits the display to records where COMNAME equals 'ROUND EBONYSHELL', showing only this single endangered species rather than all species in the source database.

Scale Information:

The map scale shows a regional view appropriate for understanding the overall geographic distribution of the species across multiple states. This scale is suitable for conservation planning and understanding broad habitat patterns but may not show fine-scale habitat details within individual water bodies.

Coordinate System:

NAD_1983_HARN_Florida_GDL_Albers (WKID 3087)

Time Period of Content:

The source dataset is dated July 2025 (CR_USFWS_POLY_JUL25), indicating the species boundary information reflects data current as of that date.

Limitations:

The map shows only officially documented habitat boundaries as recognized by the U.S. Fish and Wildlife Service. Actual species occurrence may vary, and undocumented populations may exist. The dataset specifically represents data for the State of Florida as maintained by USFWS, though the map display extends into Georgia and South Carolina, suggesting multi-state range data is included. Historical ranges or suitable habitat areas that are currently unoccupied are not shown.

Map Coverage:

The map extent covers the southeastern United States from approximately the Atlanta, Georgia area in the northwest to the southern tip of Florida, and from the Gulf of America coast in the west to the Atlantic Ocean coast in the east. The exact geographic extent includes portions of Georgia, South Carolina, and the entirety of Florida's peninsula.
