• PIF population trend score - regional

• PIF relative density score - regional, breeding season

  Relative density (RD) scores reflect the average density of a species within a given BCR relative to density in the single BCR in which the species occurs in its highest density. RD is one of two area importance measures used in the PIF assessment process. Because the score is one of...

• PIF population trend - continental

  Population Trend (PT-c) indicates vulnerability due to the direction and magnitude of recent changes in population size. Like the threats scores, PT-c actually reflects trends only within North America, even for species with ranges that extend beyond the continent. It is therefore a...

• PIF threats to breeding score - continental

  Threats to Breeding (TB-c) indicates vulnerability due to the effects of current and probable future extrinsic conditions that threaten the ability of populations to survive and successfully reproduce in breeding areas within North America (i.e., unlike other global scores, TB-c is...

• PIF action code

  Action code indicating the type of conservation action most needed for improving or maintaining current population status of each species.

• PIF threats to non-breeding score continental

  Threats to Non-breeding (TN-c) indicates vulnerability due to the effects of current and future extrinsic conditions that threaten the ability of North American breeding populations to survive over the non-breeding season. Unlike TB-c, evaluation of TN-c considers vulnerability...

• PIF breeding distribution code - global

  Breeding Distribution (BD-g) ranks indicate different levels of extinction vulnerability (global) due to the spatial extent of a species’ breeding range.

• PIF continental monitoring need score

• PIF threats to breeding score - regional

  Threats to Breeding (TB-r) indicates vulnerability due to the effects of current and probable future extrinsic conditions that threaten the ability of populations to survive and successfully reproduce in breeding areas within a given BCR. Evaluation of TB-r includes threats to...

• PIF threats to non-breeding score - regional

  Threats to Non-breeding (TN-r) indicates vulnerability due to the effects of current and future extrinsic conditions that threaten the ability of populations to survive over the non-breeding season within a given BCR. Evaluation of TN-r includes threats to habitat, as well as other...
