Restoration of Riverine Process and Habitat Suitability In the Upper Narraguagus River and Northern Stream Focus Areas (Maine): This project decreases embeddedness by mobilizing the river bed, increasing sediment sorting; increases the number and depth of pools; increases retention of allochthonous organic material that the aquatic food web relies on; reduces the dead waters and over-widened channels in legacy reservoirs; and, increases cold-water fish population resiliency to climate change. The project cost is $155,737 and the estimated socioeconomic benefit is $1.6 million.

Restoring a Brook Trout Metapopulation within the Little Cataloochee Creek & Anthony Creek Watersheds, Great Smoky Mountains National Park: The project will result in the removal of Rainbow Trout from 1.6 stream miles of the Little Cataloochee and 1.7 stream miles of Anthony Creek watersheds. Successful removal of these invasive fish will allow native Brook Trout to be re-introduced into these stream reaches. Total project cost is $234,112.

Restoring Connectivity in the West Branch Machias River, ME_FY10 Project: This project replaced two under-sized and failing road-stream crossings (culverts) with 1.2 x bankfull width open arch structures.

Restoring habitat connectivity in Machias and Saint Croix River tributary streams, ME_FY11 Project: Through this project, Downeast Lakes Land Trust (DLLT) continued its work with partners to restore brook trout habitat on priority streams within its 55,678-acre Downeast Lakes Community Forest by removing passage barriers. Of the four sites included in the original proposal (Billy Brown Brook/Shaw St., Amazon Brook/Amazon Rd., Grand Lake Brook/Fourth Lake Rd., and Fourth Lake Trib./Belden Brook Rd), two were completed using NRCS funding received after the initial proposal was submitted to USFWS. As a result, Eastern Brook Trout Joint Venture funding was used to restore fish passage at two additional sites at South Branch/Little River Rd and Towers Brook/Little River Rd.

Riparian Restoration Decision Support Tool: An innovative riparian planting and restoration decision support tool, this user-friendly tool allows managers and decision-makers to rapidly identify and prioritize areas along the banks of rivers, streams, and lakes for restoration, making these ecosystems more resilient to disturbance and future changes in climate.

Sampling strategies for estimating brook trout effective population size: The influence of sampling strategy on estimates of effective population size (Ne) from single-sample genetic methods has not been rigorously examined, though these methods are increasingly used. For headwater salmonids, spatially close kin association among age-0 individuals suggests that sampling strategy (number of individuals and location from which they are collected) will influence estimates of Ne through family representation effects. We collected age-0 brook trout by completely sampling three headwater habitat patches, and used microsatellite data and empirically parameterized simulations to test the effects of different combinations of sample size (S = 25, 50, 75, 100, 150, or 200) and number of equally-spaced sample starting locations (SL = 1, 2, 3, 4, or random) on estimates of mean family size and effective number of breeders (Nb). Both S and SL had a strong influence on estimates of mean family size and ^ Nb; however the strength of the effects varied among habitat patches that varied in family spatial distributions. The sampling strategy that resulted in an optimal balance between precise estimates of Nb and sampling effort regardless of family structure occurred with S = 75 and SL = 3. This strategy limited bias by ensuring samples contained individuals from a high proportion of available families while providing a large enough sample size for precise estimates. Because this sampling effort performed well for populations that vary in family structure, it should provide a generally applicable approach for genetic monitoring of iteroparous headwater stream fishes that have overlapping generations.

Scott Brook Fish Passage Restoration, ME_FY13 Project: This project restored ecological stream function within Scott Brook from Big Lake to the Stud Mill Road. It also provided unhindered upstream access to approximately 3 miles of habitat for Brook Trout and other native species. A prolonged sedimentation problem (water overtopping road) that was a direct result of beaver’s plugging the old undersized culvert was minimized by installing a bankfull spanning structure.
