Summary
- Status in VT: Decreased by 14% (7 to 6 blocks). Loss occurred in the Northeastern Highlands.
- Data from other research: Victory Bog: 20-year study shows fewer territorial pairs in recent years.
- Conservation status: State rank S2; SSC; SGCN-M
- Other atlases: ON: stable or increasing distribution
- VT’s role in North American range: VT is near the southern edge of the range.
- Causes of change since first Atlas: Heavy logging (?); “hoard-rot” hypothesis suggests that higher than average temperatures in autumn could contribute to poorer than average productivity in the following breeding season.
- Management/Monitoring recommendations: Monitor trends through targeted surveys; determine minimum area of suitable habitat necessary to support 500 breeding pairs.
