PRIORITY SPECIES POOL -- AREA 09
From among the breeding avifauna, a pool of species may be derived that represents priorities for conservation action within the physiographic area. Note that a species may be considered a priority for several different reasons, including global threats to the species, high concern for regional or local populations, or responsibility for conserving large or important populations of the species. The different reasons for priority status are represented by levels or tiers. Our primary means of prioritizing species is through the PIF prioritization scores generated by Colorado Bird Observatory (Hunter et al. 1994, Carter et al. 2000). This system ranks species according to seven measures of conservation vulnerability. These include four global measures (i.e., they do not change from area to area), as well as threats to breeding populations (TB), area importance (AI), and population trend (PT), which are specific to each physiographic area. A total rank score is then derived, which is a measure of overall conservation priority.
There are five entry levels into the priority species pool, as follows:
Tier I. High Continental Priority. -- Species that are typically of conservation concern throughout their range. These are species showing high vulnerability in a number of factors, expressed as any combination of high parameter scores leading to an average score > 3 (the midpoint); total of 7 parameter scores will be ≥ 22, with AI ≥ 2 (so that species without manageable populations in the region are omitted).
Tier I A. High Continental Priority - High Regional Responsibility. Species for which this region shares in major conservation responsibility; i.e., conservation in this region is critical to the overall health of this species. Species with AI of 3 - 5, or a high percent population (above threshold in II B).
Tier I B. High Continental Priority - Low Regional Responsibility. Species for which this region can contribute to rangewide conservation objectives where the species occurs. Species with AI of 2.
Tier II. High Regional Priority. Species that are of moderate continental priority, but are important to consider for conservation within a region because of various combinations of high parameter scores, as defined below; total of 7 parameter scores = 19-21.
Tier II A. High Regional Concern. Species that are experiencing declines in the core of their range and that require short-term conservation action to reverse or stabilize trends. These are species with a combination of high area importance and declining (or unknown) population trend; total of 7 parameters = 19-21, with AI + PT ≥ 8.
Tier II B. High Regional Responsibility. Species for which this region shares in the responsibility for long-term conservation, even if they are not currently declining or threatened. These are species of moderate continental priority with a disproportionately high percentage of their total population in the region; total of 7 parameters = 19-21, with % population > threshold (see Appendix 3 in this area's full Plan).
Tier II C. High Regional Threats. Species of moderate continental priority that are uncommon in a region and whose remaining populations are threatened, usually because of extreme threats to sensitive habitats. These are species with high breeding threats scores within the region (or in combination with high nonbreeding threats outside the region); total of 7 parameters = 19-21 with TB + TN > 6, or local TB or TN = 5.
Tier III. Additional Watch List. These species are on the U.S. National Watch List not included in the above tiers. These species score highly enough based on global criteria to warrant conservation attention wherever they occur with an AI of 2 or more.
Tier IV. Additional Federally Listed. Species listed under the U.S. Endangered Species Act receive conservation attention wherever they occur.
Tier V. Additional State Listed. - Species on state endangered, threatened, or special concern lists that did not meet any of above criteria. These are often rare or peripheral populations.
Species that are federally or state listed are noted on the Priority Species Pool by country and/or state using the following codes: E = Endangered, T = Threatened, SC = Special Concern, V = Vulnerable.
Note: the Priority Species Pool and Priority Habitat-suites are excerpted from the associated Physiographic Area Plan. These tables are also available as a downloadable PDF file.
Priority species pool for Southern New England, Area 09. Total scores were developed from Partners In Flight criteria (Hunter et al. 1994, Carter et al. 2000), with regional and global scores provided by Colorado Bird Observatory. Percent of population was calculated from percent of range area, weighted by BBS relative abundance (see Rosenberg and Wells 1999), except where noted. Local status codes refer to migratory status: B – species that breed within the region but do not winter there, R – resident or nonmigratory species, E – species reaching distributional limits.
