Alternative Text Description for Roseate Tern (Threatened)

TABLE OF CONTENTS

MAP OVERVIEW

This map shows the designated habitat boundaries for the Roseate Tern, a threatened species, in southern Florida waters. The map displays polygonal areas representing the species' recognized habitat as defined by the United States Fish and Wildlife Service. These areas appear primarily in marine and coastal waters extending from the southwestern coast through the Florida Keys and along portions of the southeastern coast.

GEOGRAPHIC CONTEXT

The map covers southern Florida, including the Gulf of America coastline from Cape Coral and Naples southward through the Florida Keys, and the Atlantic coastline from the Keys northward past Miami to Boca Raton. Major cities labeled on the map include Cape Coral, Naples, Immokalee, Miami, Hollywood, Coral Springs, Homestead, and Key West. The map extends southward to include the Straits of Florida and shows both marine and coastal areas. The western portion borders the Gulf of America, while the eastern portion faces the Atlantic Ocean.

KEY INSIGHTS

The Roseate Tern habitat shows a distinct coastal and marine distribution pattern concentrated in three main areas. The largest continuous zone extends along the southwestern Florida coast from near Naples southward through the Ten Thousand Islands region and wraps around the Florida Keys archipelago. A separate concentration appears along the southeastern coast near Homestead and extending into Florida Bay. The habitat is exclusively marine and coastal, avoiding inland areas entirely, and follows the configuration of Florida's southern shoreline and island chains. The distribution suggests the species relies on shallow coastal waters, island environments, and the unique marine ecosystems surrounding the Florida Keys.

VISUAL ELEMENTS

Roseate Tern (Threatened) Habitat

This layer represents the officially designated habitat boundaries for the Roseate Tern as recognized by the United States Fish and Wildlife Service.

Roseate Tern Habitat Polygons (pink crosshatch pattern)

Appearance:

The habitat areas are shown as pink polygons with a crosshatch or diagonal grid pattern overlay on a gray base map.

Distribution:

The habitat areas are distributed across three primary zones: the southwestern Florida coastal waters from the Naples/Marco Island area southward, the entire Florida Keys island chain from the Dry Tortugas through Key West and the middle and upper Keys, and portions of Florida Bay and the southeastern coast near Homestead extending toward Miami.

Notable locations:

The most extensive habitat coverage occurs around Key West and the lower Florida Keys, where multiple polygonal areas form a broad zone. Significant habitat also exists in the Ten Thousand Islands region south of Naples and Marco Island. Smaller discrete habitat areas appear west of Key West and in the waters between the mainland and the upper Keys near Homestead.

Spatial patterns:

The habitat follows Florida's coastal configuration, creating an arc from the southwestern Gulf of America coast, around the Keys, and up the southeastern Atlantic coast. The polygons vary in size, with larger continuous areas in the Keys and more fragmented patches along the mainland coasts. The habitat maintains proximity to shorelines and island systems, suggesting dependence on coastal and nearshore marine environments.

SYMBOL GUIDE

ADDITIONAL INFORMATION

This map displays only those Roseate Tern habitat areas where the display criteria is set to "Y" (yes), meaning these are the currently designated and recognized habitat boundaries. The map focuses exclusively on this single threatened species and does not show other wildlife habitat designations or conservation areas that may overlap these waters. Base map features such as cities and geographic labels are provided for spatial reference only and are not part of the thematic layer.

DATA CONTEXT

Data Source:

United States Fish and Wildlife Service polygonal boundaries dataset for threatened and endangered species in the State of Florida. The dataset contains officially recognized habitat boundaries for species under federal protection.

Definition Query:

The map displays a filtered subset of the complete dataset, showing only records where the display field equals "Y" and the common name equals "Roseate Tern." This filter isolates the habitat boundaries specifically for this threatened species.

Scale Information:

The map shows a regional-scale view appropriate for understanding the overall distribution of Roseate Tern habitat across southern Florida. This scale is suitable for conservation planning and general habitat assessment but may not show fine-scale habitat details within individual polygons.

Coordinate System:

NAD 1983 HARN Florida GDL Albers (WKID 3087)

Limitations:

The map shows designated habitat boundaries as polygonal areas, which represent generalized zones rather than precise locations where individual birds may be found at any given time. Actual species presence may vary within these boundaries based on seasonal patterns, environmental conditions, and specific habitat suitability. Areas outside the designated boundaries are not necessarily unsuitable but are not officially recognized in this dataset.

Map Coverage:

The map extent includes southern Florida from approximately Cape Coral and the Palm Beach area southward through the entire Florida Keys and surrounding marine waters, including portions of the Gulf of America, Florida Bay, and the Straits of Florida. Some context area beyond the primary habitat zones is shown for geographic orientation.
