Free

US Fish & Wildlife Service ESA-designated critical habitat — Final and Proposed critical-habitat polygons for threatened & endangered species, from the FWS hosted ArcGIS service. No auth. The #1 federal ESA Section-7 permitting screen: does a well pad, pipeline route, or right-of-way intersect designated critical habitat, and for which listed species? Query by location (near a point or bbox) and/or by species name; ask for format:'geojson' to draw the polygons on a map.

  • ⚠ This is an ESA Section 7 screening source, not a legal effect determination or complete species consultation record.

    • ⚠ Record mode omits polygon geometry to minimize tokens; request geojson only for mapping.
    • ⚠ truncated=true or complete=false means the result hit the caller/upstream limit.
    • ⚠ Proposed habitat is not legally in effect; includeProposed defaults to false.
