Holt Research Forest
The Holt Research Forest is the site of long-term ecosystem research in a Arrowsic, Maine. Arrowsic is an island that falls within Maine’s coastal climatic region and the midcoast biophysical region of Maine. This region has the greatest woody plant species richness in the state in part because it falls within the transition between the Northeastern coastal forest to the west and south and the New England/Acadian forest to the east and north. The forest is predominantly a dry ridge, oak-pine ecosystem, and the most abundant tree species by volume and number are Eastern White Pine (Pinus strobus), Northern Red Oak (Quercus rubra), and Red Maple (Acer rubrum).
The Holt Research Forest research plan emphasizes two goals: (1) Monitor long-term changes in the forest’s plant and animal populations; and (2) Document the effect of forest management on these populations. The research at Holt is currently funded by Maine TREE Foundation.
