Area Map

Mud Pond Forest is a 362-acre parcel that is dominated by northern hardwood forest with sections of northern white cedar swamp, intermediate fern, and northern hardwood seepage forest. This silvicultural treatment is on a 175-acre northern hardwood, rich northern hardwood natural community-dominated stand that is about 80-years old. There is currently minimal forest health concerns, but the arrival of Emerald Ash Borer will impact the ash resource on the property. This project strives to demonstrate how activate forest management can facilitate positive stewardship outcomes. The three focus areas occurring on tis site include: silviculture for climate change, managing for quality forest bird habitat, and management of ash in a pre-EAB infestation.


Site Location

Greensboro, Vermont

An ideal location for climate science

The Mud Pond Forest is located at the end of Hunt Avenue in Greensboro.

A winter haul road leads to a landing in the southern section of the lot. Skid trails also provide access through the property. Non-motorized, non-mechanized recreation is permitted.


Stand Information

175 acres

Northern Hardwoods

Early successional

Class I and II


Pre-treatment Conditions

The stand was partially cleared for agricultural use sometime in the past and was impacted by the 1983 hurricane.


Silviculture Prescription

Mud Pond’s goals are to establish an experiment and demonstration area that use concepts of resistance, resilience, and transition strategies in managing forests for a changing climate. Building resistance includes treatments that tend the existing forest to give healthy trees more growing space and reduced stress from water and resource competition. Resilience strategies include diversity age structure, species composition, and forest complexity through additions of dead standing and down wood. Transition strategies include the planting of trees species expected to do well in our changing climate. The treatment included three separate treatment types: group selection, irregular shelterwood, and a control, where no harvesting took place. Mud Pond Forest is a demonstration site for Silviculture with Birds in Mind for the Foresters for the Bird project. This project was created as a partnership between Audubon Vermont and the Vermont Department Forests, Parks, and Recreation. The goal of this project is to increase quality forest bird habitat through forest management and to demonstrate how active forest management can facilitate positive stewardship outcomes. The three focus areas occurring on this site include: silviculture for climate change, managing for quality forest bird habitat, and management of ash in the pre-EAB infestation. As Vermont’s forests are impacted by the compound stresses of a changing climate, fragmentation, and non-native species, it becomes more important to maintain all our native species as a mechanism to enhance resiliency. Emerald ash borer threatens the long-term existence of all species of ash native to North America. According to the latest research, the preservation of ash requires a multi-pronged approach: leaving a range of ages and sizes, regenerating ash, biocontrol’s, and insecticide treatments of small groups of seed trees. It is estimated that EAB is likely to arrive at Mud Pond Forest within the next 10 years. In 2019, a harvest was completed to demonstrate a framework for considering ash management during active harvest projects. The goals of Mud Pond Forest are to leave healthy ash trees standing. Retaining trees mean retaining genetic diversity, with the hope that some trees will have genetic resistance to the insect. Harvest to create conditions that will help new ash regenerate. Because the insect doesn’t target very young trees, we hope the new ash trees that emerge from our efforts will survive the first onslaught of the beetle. After which, we hope there will be more knowledge about what to do. Use insecticide treatments to protect some ash trees from the beetle, especially female ash trees, as their seeds are the hope of the future.

The primary goals for this site are to improve quality forest bird habitat, prepare the arrival of EAB, and mitigate future stress associated with climate change to build resilience, resistance, and transition strategies, and provide demonstration opportunity for outreach and education. To help combat EAB, the retention is based on the number of healthy crowns, but generally no lower than two trees per acre. There was an intentional effort to regenerate ash trees where they are being harvested. This is done through small canopy gap formation adjacent to female seed trees so that smaller ash can join the main canopy and harvesting small groups of low-quality ash to stimulate root sprouting. Insecticide treatments are planned for when EAB is identified within close proximity to the property.

Landowner objectives include forest health, EAB preparation, timber production, water quality, soil considerations, native biodiversity, rare plants, animals, and natural communities, historic and cultural resource considerations, wildlife considerations, deer wintering area, silviculture with birds in mind, climate change considerations, recreational considerations, aesthetics considerations, and outreach and education.

Within Silviculture with Birds in Mind, Mud Pond Forest includes annual bird monitoring each June, and active management of ash in a pre-EAB infestation. Treatment type is irregular shelterwood with crop tree release, and includes increasing sawtimber quality, quantity, and volume increments, maintain 75-80% canopy cover, enhance horizontal structure and understory development using gaps, and lastly, increase abundance of large-diameter snags, cavity trees, and downed woody material. Within Silviculture for Climate Change, 20% of the area in 0.1-0.25-acre groups, placed in areas of advance regeneration or where little regeneration exists beneath groups of economically mature trees, will be group selected with cutting cycles of 20 years. Crop tree release will be used in the matrix between groups to accelerate large tree components, marked for quality and longevity. All softwoods, and resistant crown forms will be retained, as well as existing snags and large diameter legacy trees for future snags. Up to 50 trees/acre will be released with 2–3-sided crown release. Contour-fell 2-5 whole trees per acre for downed dead wood. There will also be continuous cover irregular shelterwood to establish larger gaps (0.3-0.5-acre) in 20-25% of stand placing gaps in areas of advance regeneration or where little regeneration exists beneath groups of economically mature trees. 1-3 legacy trees will be retained in gaps, depending on the opening size to maintain a 70-92 ft acre BA. In some gaps, planting of bare-root seedlings of future-adapted northern hardwood species currently found near site in low abundance (such as red oak) or nearby northern hardwood species expected to gain suitable habitat in the region under climate change (such as black birch), and bare-rooted seedlings of conifer species historically important on site (such as red spruce), as well as expected to gain suitable habitat in region under climate change (such as white pine). Retain existing snags and large diameter legacy trees for future snags. Contour-fell 2-5 whole trees per acre for downed dead wood.

Regarding the Silviculture for Climate Change project, it was learned that changing weather patterns will create challenges during harvesting. Less reliable frozen winter conditions may require more investments in infrastructure, such as truck roads and skid trails. Extended periods of wet ground conditions after heavy rains can limit logging productivity. Within Silviculture With Birds In Mind, it was learned that short-term changes in habitat characteristics can be linked with changes in bird abundance, such as downed fine woody material (winter wren) and the establishment of canopy gaps (flycatchers). Long-term monitoring will be important to see tends in habitat conditions that take more time to develop. Within the preparation for EAB project, planning a couple years ahead is highly recommended as it’s easiest to sex trees during heavy seed years, which is episodic. It is helpful to identify female trees to ensure that regeneration conditions are being established near seed sources from female trees.
