Restoration
of High
Grade Forests
Unsuspecting
woodland owners selling timber often fall victim to the practice of
"high-grading" or cutting the best trees and leaving the rest.
Where this practice has occurred, there generally has been a decline on long
term forest health and productivity. How can woodlands impacted by this
practice be restored? On Thursday, February 14th at the Cumberland
Woodland Owners’ Association meeting, Dr. James Finley, Penn State Professor of
Forest Resources, will speak on the “Restoration of High Grade Forests in
Pennsylvania.” The meeting will be held at 7:00 P.M. at the
Cumberland County Extension Office which is located at 310 Allen Road in
Carlisle. You do not have to be a member and there is no cost to attend.
Directions are available on-line at: http://extension.psu.edu/cumberland/directions.
High
grading is harvesting only those trees that will give the highest immediate
economic return. It is also often referred to as select cutting or diameter limit
cutting
where all trees above a specified diameter are harvested. Whatever you
call it, the effect is the same....a decline on long term forest health and
productivity. High grading removes important seed sources and decreases
long term income potential. No concern is shown for the species
composition, quality, and density of the remaining forest.
Cutting
the biggest trees might produce a brief financial windfall, but the
consequences can last decades. High-grading will increase the time between
harvests while decreasing the value of those harvests. The remaining trees are
usually not as vigorous, generally more at risk from diseases and insect pests,
and more vulnerable to damage from extreme weather. The practice also can
reduce the diversity of tree species in a forest, leaving wildlife with a
diminished supply of food and shelter.
Pennsylvania’s
forests are an important renewable natural resource and include some of the
nation’s most commercially valuable hardwood species. They are not only a source of aesthetic beauty, but also
of economic viability and employment for thousands of residents. This
meeting is open to the public.
