THE DAVEY BULLETIN
SOUTHEAST U.S. IMPACTS
Extreme rain events are increasing in frequency,
with more rain events occurring as heavy downpours. This
is combined with stronger hurricanes making landfall more
often, bringing with them associated flooding from larger,
slower-moving storms and tidal storm surge intensified
by sea-level rise.
NORTHEAST U.S. IMPACTS
With winters warming faster than summers and
winter hardiness zones changing, some tree species will
benefit at the expense of others. That means distribution
of trees is changing as some species move further north.
In central West Virginia, oak and hickory are predicted to
increase in dominance, as sugar maple, beech, and gray
birch decrease. In northern Maine, spruce-fir forests will
transition to maple-beech-birch forests, which will be
replaced by oak-hickory forests in New York.
CANADA AND CLIMATE CHANGE
The next phase of the Davey climate
science project will be to develop similar
climate change projections for Canada.
