hemlock conclusions
Hemlock Conclusions

Range of HWA currently covers all networks.

Many parks have already observed significant hemlock mortality.

Expansion of HWA limited by winter temperature.

Climate change scenarios

  • High (business as usual), HWA may cover the entire range of suitable habitat for hemlock in the Northeast.
  • Low, northern New England and the Adirondack region in NY as possible refugia for hemlock and may include MABI and SAGA.

Early detection and rapid response efforts to slow the spread of HWA may buy some time for MABI and SAGA.

emerald ash borer conclusions
Emerald Ash Borer Conclusions

Emerald ash borer is spreading rapidly throughout the eastern US, and primarily dispersed by humans. Once EAB are established, ash mortality is nearly 100%.

Ash trees occur in over 90% of all parks sampled, although generally at low densities.

Low and high emission scenarios predict widespread decline in quality white ash habitat.

Unlike the range of HWA, spread of EAB does not appear to be limited by colder climates.

applications of forest monitoring data
Applications of Forest Monitoring Data

Inform parks of emerging forest health issues.

Predict impacts based on observations in other parks.

Prioritize species for early detection and rapid response efforts at park and regional levels.

Inform scenario planning for climate change adaptation, including potential desired future conditions.
