What this source cannot tell you

  • ⚠ Anything outside United States. A request past that edge comes back empty rather than approximated.
  • ⚠ Which years it spans, because the covered period is not declared.
  • ⚠ Anything US Fish and Wildlife Service Critical Habitat does not publish. ParcelOps returns this source as it stands and never fills a blank field from a different one.
  • ⚠ Screening polygons do not replace an official species consultation or legal determination.
