Contoocook River Service Area:

$24,000 for the installation of stormwater management structures to improve water quality and minimize stormwater erosion along the bank of the Contoocook River at Azalea Park in Henniker. Azalea Park is a historical landmark in downtown Henniker, located along the Contoocook River. The focus of this phase of the project is to manage the upland stormwater runoff which has been directed into a wetland in the park, causing erosion of the park entrance path and adding sediments and salt into the wetland. Managing the upland stormwater runoff and controlling the water flow into the river after storm events will help decrease the sediment washing into the river.

UpperMiddle Connecticut River Service Area:

$252,240 for the purchase of a conservation easement on the Shumway Forest, a 313-acre parcel on Moose Mountain in Hanover. The property includes the presence of headwater streams and a diversity of other valuable wetlands, presence of Tier 1 and 2 wildlife habitat and supporting landscape, the highest elevation unprotected wildlife habitat in the town, and a section of the Appalachian National Scenic Trail. The parcel provides conservation linkages within a large block of unfragmented forest on Moose Mountain in the Quabbin to Cardigan region.

Upper Connecticut River Service Area:

$79,800 to protect and restore 71.57 acres of high conservation-value riverine habitat, floodplain forest and farmland along 1.6 miles of the Connecticut River in Colebrook. The Nature Conservancy will acquire the fee interest in the Brunault tract and subsequently transfer ownership to NHFG. The project will result in the permanent protection of 3.4 contiguous miles of Connecticut River shoreline on the New Hampshire side. The protection of the Brunault property will contribute to a 970-acre block of protected conservation land on both sides of the river. Restoration of the parcel’s floodplains will create a more resilient ecosystem, ensuring dynamic river processes, such as channel migration that creates oxbows and sandbars for pioneer species recruitment. It will also help ensure the protection of four state-listed endangered plants found on the property. The floodplain forest on the Brunault tract is also part of a rare natural community in the watershed.

$15,000 for aquatic restoration work in the Nash Stream watershed in Stratford and Odell. The project is a phased, multi‐year effort to restore channel processes and habitat quality/connectivity so that the watershed supports an intact aquatic ecosystem, including native coldwater fish. In this second phase of tributary wood replenishment, Trout Unlimited proposes to add wood to the channel and restore up to 3.2 miles of instream and riparian habitat that was impaired by historic logging activities in the East Branch and Long Mountain Brook which are direct tributaries to Nash Stream. The project ultimately will restore over nine miles of mainstem and ten miles of tributary habitat, and reconnect over six miles of tributaries.
