Culvert Retrofit for Aquatic Passage Restoration, Kirby Brook, Washington, CT: The project purpose is to use stream simulation design techniques to retrofit an existing barrier culvert on Kirby Brook, in order to restore full aquatic organism passage through the structure, opening up an additional 1.8 miles of high-quality fish habitat in Kirby Brook and its tributaries.

Culvert Replacement, Blue Lick Run Tributary, Avilton, MD: The project restored connectivity within the Savage watershed, Maryland’s best EBT resource, improving fish passage to largely forested upstream habitat. Connectivity will increase population resilience and genetic diversity by providing access to cold water refugia during low flow periods and increasing foraging and spawning habitat availability.

Climate change influence on brook trout populations in the Central Appalachians - Andrew et al. 2022: We used a 18-year brook trout (Salvelinus fontinalis) data set with samples across a ~4800 km2 spatial area in the Central Appalachian Mountains, combined with PRISM climate data at the HUC-12 subwatershed level to investigate temporal trends of each. his work provides long-term evidence to help understand the dynamics of these sentinel headwater fish populations as they experience a changing climate.

Conservation planning at the intersection of landscape and climate change: brook trout in the Chesapeake Bay watershed: We developed a multi-scale conservation planning framework for brook trout (Salvelinus fontinalis) within the Chesapeake Bay watershed that incorporates both land use and climate stressors. Our specific objectives were to (1) construct a continuous spatial model of brook trout distribution and habitat quality at the stream reach scale; (2) characterize brook trout vulnerability to climate change under a range of future climate scenarios; and (3) identify multi-scale restoration and protection priorities for brook trout across the Chesapeake Bay watershed. Boosted regression tree analysis predicted brook trout occurrence at the stream reach scale with a high degree of accuracy (CV AUC = 0.92) as a function of both natural (e.g., water temperature and precipitation) and anthropogenic (e.g., agriculture and urban development) landscape and climatic attributes. Current land use activities result in a predicted loss of occurrence in over 11,000 stream segments (40% of suitable habitat) and account for over 15,000 km (45% of current value) of lost functional brook trout fishery value (i.e., length-weighted occurrence probability) in the Chesapeake Bay watershed. Climate change (increased ambient temperatures and altered precipitation) is projected to result in a loss of occurrence in at least 3000 additional segments (19% of current value) and at least 3000 km of functional fishery value (9% of current value) by 2062. Model outcomes were used to identify low- and high-quality stream segments within relatively intact and degraded sub-watersheds as restoration and protection priorities, respectively, and conservation priorities were targeted in watersheds with high projected resilience to climate change. Our results suggest that traditional restoration activities, such as habitat enhancement, riparian management, and barrier removal, may be able to recover a substantial amount of brook trout habitat lost to historic landscape change. However, restoration efforts must be designed within the context of expected impacts from climate change or those efforts may not produce long-term benefits to brook trout in this region.

SENSITIVITY AND VULNERABILITY OF BROOK TROUT POPULATIONS TO CLIMATE CHANGE: We directly measured paired air and water temperatures in watersheds (N = 77) containing reproducing populations of brook trout in Virginia. We found that paired air and water temperature relationships are highly variable among patches but are a useful dataset to classify sensitivity and vulnerability of existing brook trout patches. We developed a classification system using sensitivity and vulnerability metrics that classified sampled brook trout habitats into four categories (High Sensitivity- High Vulnerability (51.9%); High Sensitivity-Low Vulnerability (10.4%); Low Sensitivity-High Vulnerability (7.8%); Low Sensitivity-Low Vulnerability (29.9%). Our direct measurement approach identified potential refugia for brook trout at lower elevations and with higher air temperatures than previous larger scale modeling efforts.
