Massachusetts Important Bird Areas
IBA Criteria Category 4
Sites
containing assemblages of species characteristic of a representative,
rare, threatened, or unique habitat within the state or region.
This
category is meant to cover relatively large areas capable of supporting
significant bird populations, especially of species with specialized
habitat types and requirements. Selection of sites will
be based on avian assemblages within the habitat community type,
not on the habitat community type alone. Therefore, whenever possible,
characteristic species of birds indicative of the habitat type should
be identified and quantified.
Major avian habitat types and categories in Massachusetts:
- Spruce/Fir forest
- Northern hardwood forest
- Oak/conifer transitional forest (Red Oak, Eastern Hemlock, White Pine, etc.)
- Pitch Pine/Scrub Oak forest
- Early successional shrubland
- Cultural grassland
- Cultivated field
- Emergent freshwater wetland (i.e. cattail marsh)
-
Peatlands (bogs and fens)

- Palustrine wooded swamp (White Cedar, Red Maple, or floodplain)
