- Status in VT: Decreased by 31% (142 to 98 blocks). Losses in all biophysical regions except Northeastern Highlands and Vermont Valley. Greatest loss in the Southern Vermont Piedmont.
- Data from other research: VFMP data show an annual trend of -6.7% at 12 sites from 1989 to 2006 (Rimmer, Faccio, and McFarland 2007).
- Conservation status: State rank S4B; SSC; SGCN-H
- Other atlases: NY: -23%
- VT’s role in North American range: VT is within the core of the range.
- Causes of change since first Atlas: Loss of two forest cover types that are important to this species: spruce-fir and elm-ash-red maple; loss of forested wetlands; loss or degradation of habitat on wintering grounds.
- Management/Monitoring recommendations: Forest managers should provide dense regenerating forests that have emergent, mature trees; protect red maple swamps; see “Canada Warbler – Population Status, Habitat Use, and Stewardship Guidelines in Northeastern Forests” (PDF).
