I am concerned about maintaining local gene pools, especially of forest species, so am somewhat concerned about replacing indigenous American Beech with trees from an outside stock. Will the DNR obtain the replacement seedlings from within Tahquamenon Falls State Park or general area? Personally, when I walk through a natural area, I like to know that the species I see are those of the original post-glacial stock and not transplanted from hundreds of miles away. Does anyone here have any good research on the regional genetic variations of American Beech and other trees.

Thank you.

TREES AT TAHQUAMENON FALLS STATE PARK
INFECTED WITH BEECH BARK DISEASE

LANSING--The Michigan Department of Natural Resources plans
to remove up to 95 beech trees infected with beech bark
disease from the two campgrounds at Tahquamenon Falls State
Park.
Bob Heyd, DNR Forest Health Specialist, inspected the trees
and confirmed the presence of beech bark disease. "Infested
trees, especially dead and dying ones, are a safety hazard
to the public," Heyd said. "Removing them is the most
responsible course of action."
Beech bark disease causes significant mortality and defect
in American beech. The disease results when bark is attacked
by the beech scale, an immobile insect that removes tree sap
by inserting its needle-like mouthpart into the bark. Scale
feeding stresses the tree and provides points of entry for a
fungus, which is the primary damaging agent. Beech bark
scale appears as white cottony spots, which can completely
cover the mainstem of a beech in outbreak areas.
Beech bark disease is one of the latest exotic pest problems
to plague Michigan forests. It accidentally was introduced
into Nova Scotia in 1890 on ornamental beech imported from
Europe. By the early 1930s, the scale and associated Nectria
fungi were found throughout the Maritime Provinces in Canada
and in localized areas of Maine. Beech bark disease was
discovered in Michigan this year for the first time.
As the disease runs its course, the DNR expects more beech
trees to be lost. Early diagnosis, however, allows
replacement trees to be planted now.
"We realize the removal of these mature, magnificent trees
will impact the aesthetic beauty of our park," said Chuck
Wieringa, Tahquamenon Falls State Park Manager, "but
planting new trees will maintain our natural setting and
ensure that Tahquamenon Falls remains one of the most
pristine parks in our system."
