Georgia Stream Crossing Handbook: This handbook is intended to encourage the proper design and implementation of all new stream crossings in Georgia to maintain stream connectivity, improve stream health, provide for public safety, improve water quality, and make communities more resilient. Originally published in 2012, this 2021 update represents the work of 18 authors drawn from State and Federal Agencies, NGOs, academia, and private firms.

Restoration of brook trout across their native range using fish toxicants and electrofishing: are we successful ecologically and socially?: PDF of PowerPoint presentation by Matt Kulp, fishery biologist with the Great Smoky Mountains National Park, and coauthors, reviewing historic and contemporary restoration efforts to restore brook trout using toxicants and electrofishing. Matt surveyed state and agency biologists about projects to remove invasive species and replace brook trout. This presentation and associated database describe the outcomes and factors in success and failures.

Development of Genetic Baseline Information to Support the Conservation and Management of Wild Brook Trout in North Carolina: Kazyak, D.C., Lubinski, B.A., Rash, J.M., Johnson, T.C., King, T.L. 2021. After centuries of declines, there is growing interest in conserving extant wild populations of Brook Trout Salvelinus fontinalis and reintroducing Brook Trout populations of native ancestry. A population genetic baseline can enhance conservation outcomes and promote restoration success. Consequently, it is important to document existing patterns of genetic variation across the landscape and translate these data into an approachable format for fisheries managers. We genotyped 9,507 Brook Trout representing 467 wild collections at 12 microsatellite loci to establish a genetic baseline for North Carolina, USA.

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.

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.

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.

Beaver: Nature's ecosystem engineers: This review summarizes how beaver impact: (a) ecosystem structure and geomorphology, (b) hydrology and water resources, (c) water quality, (d) freshwater ecology, and (e) humans and society. It concludes by examining future considerations that may need to be resolved as beavers further expand in the northern hemisphere with an emphasis upon the ecosystem services that they can provide and the associated management that will be necessary to maximize the benefits and minimize conflicts.
