The PMRC Mission


The Proctor Maple Research Center is a Field Research Station of the Department of Plant Biology in the College of Agriculture & Life Sciences at the University of Vermont.

Basic and applied maple research at the University of Vermont (UVM) began in the early 1890's. The Proctor Maple Research Center was established in 1946 with the donation of the former Harvey Farm in Underhill Center, Vermont, to the University of Vermont by Governor Mortimer Proctor.  Research has centered on the sugar maple tree (Acer saccharum Marsh.) and its products--sap and syrup. Funding for research comes from Federal, State, and private sources. Much of the applied research has provided new and/or improved techniques for efficient sap collection and evaporation systems and for improvement of maple syrup quality while basic research has contributed to an improved understanding of the physiology and towards the continued health of sugar maple trees.

Research    The mission of the Proctor Maple Research Center is divided into three categories; Research, Demonstration, and Education.

     Maple research conducted at the Proctor Center has  increased knowledge of the sap flow mechanism, weather variables affecting sap yield, carbohydrate metabolism, sap biochemistry and  microbiology, syrup chemistry, and wood anatomy and physiology.  Other work has examined the health of sugar maple in relation to various biotic  and abiotic stresses, including climate and nutrition.

   There are two major stands of sugarwoods and a modern sugarhouse that support our demonstration sugaring operation.   We put out   approximately 1,550 taps  to produce 750 to 950 gallons of maple syrup each year, all of which is sold through the University of Vermont    bookstore.

The Center is used as a field classroom for students, scientists in many disciplines, and for maple syrup producers. The education mission is accomplished through presentations, demonstrations, and tours. Visitors to our site are welcome by appointment, however we are generally not able to schedule tours during the sugaring season (mid-February through mid-April). We also work closely with the UVM Extension maple specialists to provide maple education opportunities to groups and individuals throughout Vermont and the northeast region.
