Brook Trout (Salvelinus fontinalis) are New Hampshire’s state fish and recognized as an indicator species, residing in cool, clean water. Their historic range continues to decline, including 39% of populations becoming reduced and 29% extirpated (Thieling 2006). Our goal was to document population demographics and movement across three streams before watershed-wide restoration. This research provides critical baseline data to understand the effectiveness of road crossing replacement to restore connectivity. We reflect on historic landscape influences and provide management recommendations to improve Brook Trout viability across the most intact portions of their native range.
