Beginning in 2014, Trout Unlimited has been working with the USDA Natural Resource Conservation Service (NRCS) to monitor and restore instream fish habitat at 23 NRCS Wetlands Reserve Program (WRP) conservation easements in southern New Hampshire. The goal of these restorations is to reintroduce large wood into sections of stream where the natural recruitment of large instream wood becomes limited. Our restoration projects aim to improve instream habitat & structure for fish and also influence spawning potential by improving sediment transport, pool/riffle runs, and stream cover. Throughout the summer seasons, streams at each easement have had water parameters recorded and samples collected to analyze nutrient content. This has allowed us to establish the current water quality & habitability of streams for each easement. This information will serve to better identify the value of large wood additions in smaller order streams and understand the intrinsic value instream wood has on restoring fish habitat.
