MOBILIZING COMMUNITY INVOLVEMENT TO EXPAND RESEARCH: THE EFFECTS OF HISTORIC LAND-USE ON WILD BROOK TROUT (SALVELINUS FONTINALIS) IN NEW HAMPSHIRE
Wild populations of Brook Trout (Salvelinus fontinalis) are the only native stream dwelling trout species in the eastern US and populations have drastically declined across their historic range. The headwaters of the Beebe River (Campton and Sandwich, NH) possess intact, robust populations of wild Brook Trout. Paralleling the Beebe River, a road and powerline traverse five tributaries with road crossings ranging from no impact to a complete barrier to aquatic organism passage. We hypothesize human manipulation has led to measurable negative impacts on trout movement and population demographics across this watershed. To measure the current influences, we have collaborated with NH Fish and Game Department to conduct two years of monitoring populations prior to crossing replacement (2017). Our data suggests undersized crossings and riparian loss has decreased population sizes, limited movement, reduced age structure and degraded stream habitat. Research integrates multiple approaches to iterative public inclusion through outreach presentations, volunteer-reliant field sampling and student mentoring, expanding value beyond science. This project is a unique opportunity to document and track the impacts human manipulation prior to restoration while increasing awareness and partnerships involving Brook Trout management throughout northern New England.
