sales before or as EABs strike a stand.
The price of ash has been up recently,
and such sales have been profitable
Gustafson said. But the snags and fallen
timber left where ash isn't harvested and
dies also make decent wildlife habitat.
Capitalizing Birds
Mary Jo Casalena, Game Commission
turkey biologist, likened the passing of ash
to the loss of American elm.
Turkeys, she said, would benefit from
the openings in the forest canopy created
by dead ash trees.
"But we'd benefit more from stormcaused blowdowns than the complete loss
of a native tree," she said. "It's just another
blow to the continuing decline of native
biodiversity."
Gypsy moths helped grouse populations at a landscape scale in Pennsylvania, and EABs also might provide some
2 2
benefit to grouse, offered Lisa Williams,
Game Commission grouse biologist.
"But the cost is very steep in terms of
plant biodiversity and waning diversity of
food sources," Williams explained. "None
of us wish for widespread forest disease,
tornadoes, or severe wildfires. But when
humans can't make enough habitat for
severely declining species, can we perhaps be forgiven for a slight sigh of relief
for grouse when nature does it?"
The principal immediate beneficiaries
to ash die-offs have been woodpeckers,
particularly pileated woodpeckers. They
shave ash trunks of their vertical ridges
and surface bark, exposing the reddishbrown cambium interior where EAB
larvae feast.
Smaller woodpeckers then visit the
picked trunks.
Woodpecker populations have been
stable or increasing in regions where EAB
infestations have occurred, according
to the U.S. Department of Agriculture's
Forest Service.
A study showed the Detroit area's
EAB invasion augmented red-bellied
woodpecker and white-breasted nuthatch
populations from 2002 to 2011. Downy
and hairy woodpeckers also increased
after initially declining.
"The emerald ash borer has been massively destructive because most North
American ash trees have little or no
defense against it," U.S. Forest Service
entomologist Andrew Liebhold said in
a news release. "We can take heart that
native woodpecker species are clearly figuring out that EAB is edible, and this new
and widely abundant food source appears
to be enhancing their reproduction."
Woodpeckers seem to find EAB larvae
through trunk tapping. Overwintering prepupal larvae have completed development
and are no longer feeding or moving,
