1Colorado Natural Heritage Program ranking

  • G1 - critically imperiled globally (5 or fewer occurences or very few remaining individuals); critically endangered throughout its range
  • G2 - imperiled globally (6 to 20 occurrences); endangered throughout its range
  • G3 - very rare or local throughout its range or found locally in a restricted range (21 to 100 occurences); threatened throughout its range
  • G4 - apparently secure globally, though it might be quite rare in parts of its range, especially at the periphery
  • G5 - demonstrably secure globally, though it might be quite rare in parts of its range, especially at the periphery
    • T - taxa of subspecies or varieties, ranked on same criteria as G1-G5
  • GQ - Indicates uncertainty about taxonomic status
  • S1 - critically imperiled in Colorado (5 or fewer occurences or very few remaining individuals); critically endangered throughout Colorado
  • S2 - imperiled in Colorado (6 to 20 occurrences); endangered or threatened in Colorado
  • S3 - rare in Colorado (21 to 100 occurences)
  • S3S4 Watchlisted; specific occurrence data are collected and periodically analyzed to determine whether more active tracking is warranted 
  • S#B - refers to the breeding season imperilment of elements that are not permanent residents
  • S#N - refers to the non-breeding season imperilment of elements that are not permanent residents; where no consistent location can be discerned for migrants or non-breeding population, a rank of SZN is used
  • SZ - migrant whose occurences are too irregular, transitory and/or dispersed to be reliably identified, mapped and protected
  • S#? Indicates uncertainty about an assigned state rank
