 Interpretation Guide


Eastern hemlock a narrowly distributed (7.8% of area), sparse, but high importance species, and is in danger due to the hemlock woolly adelgid, which itself has been moving north and attributed to the warming climate. So it has a low adaptability which may swamp out direct climate effects. Nonetheless, our models also show a small decline in habitat primarily under the harsh 8.5 scenario. Thus it gets a poor capability to cope. SHIFT shows both infill as well as migration into unoccupied portions of Maine.
