Silviculture Prescription : South River 2016, Western Connecticut Valley, South River State Forest, Conway, MA
Bibliographic record
Abstract
The South River State Forest is located in the town of Conway along the Deerfield River south of Bardwell Ferry.It was transferred to DCR (DEM) in 1965 as part of a land swap with a major utility company and prior to that it was held in private ownership.The forest was managed for timber, fuelwood and Christmas trees in cooperation with the Commonwealth of Massachusetts Forestry program which provided management services to the previous landowner since the 1950's.This site was selected for a vegetation management project in order to continue with projects that were started over fifty years ago and complies with the DCR Management Guidelines for Woodlands.The Ecosystem Services section of these guidelines provides a number of goals that would be met by this forest management project including the protection of forest productivity with the state of the art sustainable forestry, sustainable production of renewable wood products and the ecological restoration of degraded natural community types.The project area contains red pine and Norway spruce plantations that are declining in health and vigor.Hemlock trees are showing advanced signs of Hemlock Wooly Adelgid and Hemlock Elongated Scale infestation which will quickly kill the host trees.Emerald Ash Borer has been found nearby forested areas.This forest is even-aged in structure as a result of past historical use for pasture.A conversion to an all-aged structure is prescribed in this project to increase the number of age classes represented in the forest and increase the resiliency to catastrophic natural events such as hurricanes and tornadoes.It is with these reasons in mind that a variety of silvicultural techniques can be demonstrated and applied to restore plantations to native species, salvage dead and dying trees, create new age classes, control invasive species and provide benefits to wildlife.The South River State Forest is an isolated 450 acre block of forestland with no developed facilities.This project was chosen for forest management with the following goals in mind:1. Meets DCR guidelines for management in designated woodlands. Increase forest diversity by removing non-native plantations.3. Diversify even-aged structure towards a multiple age forest structure.4. Ability to serve as a demonstration area for sound silvicultural principles. 5. Opportunity to repair and maintain access infrastructure.6. Demonstrate Best Management Practices applied to timber harvesting.7. Provide access control against illegal vehicle usage.8. Implement strategy for Climate Change by manipulating species composition.9. Salvage White ash being impacted by Emerald Ash Borer.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
