IBA Criteria Category 2
Sites regularly holding significant numbers of species of high conservation priority in Massachusetts.
Sites that regularly support significant breeding or nonbreeding densities of the following species identified as high conservation priorities by Partners in Flight (excluding state-listed species already mentioned above). Thresholds will vary but may include sites with 25 or more breeding pairs, 5% or more of the state population (if known), or the two to three sites in the state containing the highest regularly occurring numbers. May also include sites with significant complements of species.
High Conservation Priority Species
Species were chosen for the following reasons:
- They are of conservation concern throughout their range and show high vulnerability in a number of factors.
- They are of moderate continental priority but are important to consider for conservation within a region.
- They are on the U.S. National Watch List.
These are species that score high enough on global criteria to warrant conservation attention wherever they occur. Included in these lists are songbirds that have a significant proportion of their total population within Massachusetts and shorebirds that occur in Massachusetts during the breeding season or in migration that have been identified as high conservation priority based on National Shorebird prioritization ranking.
