Middlebury College
OP-11: Biodiversity

The College owns and manages about 3200 acres of land (not including the campus) that is part of the UNESCO Lake Champlain Watershed/Adirondack Biosphere Reserve. It also owns and manages about 2500 acres of land that is adjacent to the Breadloaf Wilderness of the Green Mountain National Forest.

The College hired an ecologist to conduct an assessment of all College owned lands near the main campus and at the Breadloaf Campus adjacent to the Breadloaf Wilderness and other lands nearby. From the Executive Summary: "The purpose of this study was to provide ecological information to decisionmakers, researchers, teachers, students and general users of the 1,256 ha (3,105 ac) of Middlebury College-owned forests, fields and wetlands in the Green Mountains. Fieldwork was conducted over the course of two summers, 2011 and 2012, by walking routes across the lands to make systematic observations of natural communities and vascular plants and occasional observations of wildlife sign and wildlife habitat features such as mast stands, cavity trees and Vernal Pools with amphibian activity. A map of upland and wetland natural communities was completed during the summer of 2013 using ArcGIS 10.1. The map should be seen as our best representation of the lands’ ecosystems, and as being open to future revisions and updates. Lists and maps of rare and uncommon vascular plant species were also produced. Natural communities and plant species were classified, described and ranked according to standard methodology used by natural heritage programs in the United States and numerous other countries."

From the Executive Summary: "Through our intensive field work, we mapped 37 natural community types. Of the 21 upland types, all are forested communities except for one cliff and two woodland types. The 15 wetland types consist of eight non-forest (shrub and herbaceous) and seven forest types. The general landscape pattern shows a forest matrix of different sorts of Northern Hardwood Forest with hemlock or hemlock-spruce-Northern Hardwood Forest types prominent in lower parts of the landscape. Montane conifer or coniferhardwood forest types cap the Green Mountain summits and ridgeline. The upland forest ecosystem diversity features seven Northern Hardwood Forest types, eight hemlock or mixed conifer-hardwood types, and two spruce-fir types. Within this upland forest matrix are many small- and medium-size wetlands, including scattered small seepage swamps and several rather extensive seepage forests. On the Green Mountain escarpment (parts of Middlebury Gorge and all of Battell Research Forest and Clapp Lot), Hemlock, Temperate Hemlock, and Mesic Red Oak-Northern Hardwood Forests are common, included are less extensive patches of Dry Oak and Red Pine Forests and small woodlands and temperate acidic cliffs and outcrops...Two natural community types considered rare from a statewide perspective occur on the college mountain lands in the Bread Loaf vicinity; both are part of riverine systems—Sugar Maple-Ostrich Fern Riverine Floodplain Forest and River Cobble Shore. No types ranked very rare were observed on college lands. Additional rare types, Red Pine Forest and Dry Oak Woodland, occur on the escarpment at Battell Research Forest and the Clapp Lot, respectively. Thirteen uncommon types occur on the lands and comprise substantial acreage. They include upland and wetland forest types, as well as one woodland and two non-forested wetland types. Within the study area, only Northern Hardwood Forest and Alder Swamp are ranked in the most common category." ...

Our master plan calls for the creation and/or preservation of wildlife habitat. One example of how we create wildlife habitat is by not mowing certain parts of campus lawns, which provides important habitat for pollinators including native bees. In fields used for biology research mows are timed such that they allow fledgling birds to leave their nests safely before the area is mowed. The above mentioned ecological assessment of College lands and wildlife habitat has been provided to the Buildings and Grounds committee of the Board of Trustees for consideration in future land management decisions. url's: http://www.middlebury.edu/media/view/210711/original/MP8A_naturalsystems.pdf http://www.middlebury.edu/media/view/210721/original/MP8B_naturalsystems.pdf
