UWSP campus plan for dealing with the Emerald Ash Borer (
A brief history of the Emerald Ash Borer (Agrilus planipennis
Fairmaire); It arrived in the United
States in 2002 through the port of Detroit. EAB has been spreading throughout the United States since then killing
millions of ash trees.
The Beetle only affects ash trees. Actually, it is the EAB larvae
that does the damage to the ash trees. The larvae feed just beneath the bark and cut off the vessels that
transport nutrients and water throughout the tree, eventually killing the tree.
UWSP has developed a plan for the Emerald Ash Borer (EAB) infestation which has been detected in the city of Stevens Point.
Three blocks from the UWSP campus, the city of Stevens Point has detected an
infestation of the EAB on Center Street. The UWSP Facility Services tree plan has emphasized diversity in its tree
species and this is a perfect example why. UWSP has just over 2000 trees on campus. Of those trees we have 109 ash trees that potentially can be affected by
the EAB. That adds up to about 5% of our
campus trees that could be potentially lost to this beetle.
WE should be very proud of our management of our trees on
campus, to have such a diverse amount of
tree species. It is critical to have
this type of diversity when issues like this present themselves. Possibly
losing 5% of our trees is manageable.
Some municipalities have 30-50% ash that make up their tree inventory
and this beetle will have a devastating impact on their community.
The Campus plan to manage this infestation includes the
- Facility Services is
collaborating with the College of Natural Resources. Specifically with Dr. Rich Hauer (Forestry
Professor) who has hired a student and has created a research project for this
student. For the next 3 years Dr. Hauer
has funding for the student and chemicals.
They will be doing a variety of research. Using different methods to treat the ash
trees and at different frequencies. All
the trees will be tagged with a number to assist in the research.
- After this 3 year program, we will re-evaluate
the management plan and see if funding sources will continue or we will explore finding other
funding sources to continue to pay for the treatments. If that is not possible, we will start
removing ash trees based on their health.
- Below is a map of locations for all the ash trees on campus (this does not include Schmeeckle Reserve). Over the next 3 years we will be planting a
variety of trees in the areas around our ash trees in preparation for
a possible future removal of the ash tree. Planting new trees in these areas will help reduce the canopy loss if or
when an ash tree needs to be removed.
