Alternative Text Description for Imperiled Beach Nesting Bird Breeding Sites

TABLE OF CONTENTS

MAP OVERVIEW

This map displays imperiled beach nesting bird breeding sites along Florida's coastline. The map shows the distribution of breeding locations for four species of threatened or endangered shorebirds: American oystercatcher, black skimmer, least tern, and snowy plover. Each species is represented by a distinct colored line following the coastal areas where breeding activity has been documented through the IBNB ShoreMapper data collection tool.

GEOGRAPHIC CONTEXT

The map covers the entire state of Florida and portions of adjacent states including southern Alabama and Georgia. Major cities labeled include Pensacola in the western panhandle, Tallahassee in the north-central area, Jacksonville on the northeast coast, Orlando in central Florida, Tampa on the west-central coast, and Miami on the southeastern tip. The map shows Florida's extensive coastline bordering the Gulf of America to the west and south, and the Atlantic Ocean (labeled as Straits of Florida) to the east and southeast. Notable geographic features include the Apalachicola National Forest in the panhandle, Everglades National Park in the southern tip, Great White Heron National Wildlife Refuge in the Florida Keys, and Dry Tortugas National Park west of the Keys. Major interstate highways I-10, I-75, and I-95 are visible crossing the state.

KEY INSIGHTS

Imperiled beach nesting bird breeding sites are concentrated almost entirely along Florida's coastal perimeter, with virtually no inland breeding locations documented. The distribution follows the entire coastline continuously from the western panhandle through the peninsula and around the Florida Keys. There is particularly dense concentration of breeding sites along the Gulf of America coast of the panhandle between Pensacola and Apalachicola, along the Atlantic coast from Jacksonville southward through Palm Coast, and throughout the southwestern Gulf coast near Tampa and southward. The map reveals that these imperiled species depend exclusively on coastal beach habitat for breeding, with their range forming an unbroken band around Florida's shoreline.

VISUAL ELEMENTS

Imperiled Beach Nesting Bird Breeding Sites

This layer represents documented breeding locations for four species of imperiled shorebirds along Florida's coastline, collected through the IBNB ShoreMapper tool.

American Oystercatcher Breeding Sites (bright yellow-green line)

Appearance: Represented by a bright yellow-green or lime-colored line following coastal areas.

Distribution: Present along portions of both the Gulf of America and Atlantic coasts. Notable concentrations appear along the Atlantic coast from Jacksonville southward and along sections of the Gulf coast in the panhandle and southwestern peninsula.

Notable locations: Significant presence near Jacksonville, Palm Coast area on the Atlantic side, and along the Gulf coast near Tampa and southward through the southwestern coastline.

Spatial patterns: Forms continuous or near-continuous segments along stretches of coastline rather than isolated points, suggesting breeding colonies or territories distributed along suitable beach habitat.

Black Skimmer Breeding Sites (blue line)

Appearance: Represented by a blue line following coastal areas.

Distribution: Present along both Gulf of America and Atlantic coastlines with widespread distribution throughout Florida's coastal perimeter.

Notable locations: Visible along the panhandle Gulf coast, scattered locations along the peninsula's Gulf coast, and portions of the Atlantic coast.

Spatial patterns: Appears in shorter segments compared to other species, suggesting more localized breeding colonies or more selective habitat requirements.

Least Tern Breeding Sites (red line)

Appearance: Represented by a red or coral-red line following coastal areas.

Distribution: The most extensively distributed species shown on the map, present along virtually the entire Florida coastline including the panhandle, both coasts of the peninsula, and the Florida Keys.

Notable locations: Continuous presence from Pensacola around the entire Gulf of America coast, throughout the Florida Keys, and along the Atlantic coast from Miami northward to Jacksonville and beyond.

Spatial patterns: Forms the most complete coastal circuit of all species shown, indicating the broadest distribution and most extensive use of Florida's coastal breeding habitat among the four imperiled species.

Snowy Plover Breeding Sites (magenta/purple line)

Appearance: Represented by a magenta or purple-pink line following coastal areas.

Distribution: The most restricted distribution of the four species, primarily concentrated in the western panhandle and scattered locations along the Gulf coast.

Notable locations: Heaviest concentration between Pensacola and the Apalachicola area in the panhandle, with additional scattered sites along the southwestern Gulf coast and limited presence in the Keys area.

Spatial patterns: Distribution is notably discontinuous with significant gaps between breeding locations, suggesting the most specialized habitat requirements or most restricted range among the four species mapped.

Overlapping Patterns

Many coastal areas show multiple colored lines in close proximity or overlapping, indicating that different imperiled species share breeding habitat in the same general locations. These multi-species breeding areas are particularly evident along the Gulf coast of the panhandle, sections of the southwestern Gulf coast near Tampa and southward, and portions of the Atlantic coast near Jacksonville and Palm Coast. The overlapping patterns suggest that certain coastal areas provide suitable breeding habitat for multiple imperiled shorebird species simultaneously.

SYMBOL GUIDE

ADDITIONAL INFORMATION

This map represents breeding site data specifically and does not show foraging areas, migration routes, or non-breeding habitat use. The linear representation along coastlines indicates the presence of breeding activity in those areas but does not show the precise boundaries of individual nesting colonies or the number of breeding pairs at each location. The data is collected and updated annually through the IBNB ShoreMapper tool on April 1st of each year, and represents observations submitted to the Florida Shorebird Database by researchers, managers, and conservationists. The map focuses solely on these four imperiled species and does not represent all shorebird or seabird species that may nest in Florida.

DATA CONTEXT

Data Source: The data represents imperiled beach nesting bird breeding sites collected through the IBNB ShoreMapper tool. Information is submitted to and managed through the Florida Shorebird Database (FSD), which serves as the central repository for shorebird and seabird observation data in Florida. Data is contributed by researchers, managers, conservationists, and permit reviewers to support conservation efforts. Data source layer name: IBNB_BREEDING_SEP24.

Definition Query: Definition query information was not provided for this map.

Scale Information: The map shows a statewide view of Florida appropriate for understanding broad distribution patterns of breeding sites. This scale is suitable for regional planning and conservation prioritization but does not show individual nest locations or colony boundaries.

Coordinate System: NAD_1983_2011_Florida_GDL_Albers (WKID 6439).

Time Period of Content: Data within ShoreMapper are updated annually on April 1st of each year. The specific data version shown is IBNB_BREEDING_SEP24, indicating September 2024 data.

Limitations: The map represents documented breeding sites based on submitted observations and may not capture all breeding locations if areas have not been surveyed or if data has not been submitted to the database. The linear coastal representation does not show the spatial extent of individual breeding colonies or precise nest locations. The data depends on voluntary submission by observers and may reflect survey effort as well as actual species distribution.

Map Coverage: The map covers the state of Florida in its entirety, including the panhandle, peninsula, and Florida Keys, with portions of adjacent states (southern Alabama, southern Georgia) shown for geographic context. The map extends into the Gulf of America to the west and the Atlantic Ocean/Straits of Florida to the east and south to show offshore areas and keys.
