Project Octet Stream Big Run Restoration, West Virginia
The Big Run project is part of Trout Unlimited’s Home Rivers Initiative Potomac Headwaters Restoration Project. The stream has suffered habitat degradation in the riparian zone, stream banks and instream due to long-term livestock grazing. There currently exists a lifetime grazing allotment on that portion of the Monongahela National Forest that supports Big Run. The Forest Service, Trout Unlimited and others have teamed up to work with the allotment holder to fence the riparian zone, create crossings and alternative water sources to completely remove the cattle from the stream. Over time, riparian reforestation will stabilize banks and provide vital shade during warm summer months. This is the initial project on Big Run. Resources have already been secured to move down stream on the Forest and on to private property. The project will include informational and educational kiosks and trails that will improve access for anglers and hikers. The project will restore 45 acres of riparian forest and enhance 1.5 miles of stream habitat.

File Dynamics and regulation of the southern brook trout (Salvelinus fontinalis) population in an Appalachian stream
1. We used information theoretic statistics [Akaike’s Information Criterion (AIC)] and regression analysis in a multiple hypothesis testing approach to assess the processes capable of explaining long-term demographic variation in a lightly exploited brook trout population in Ball Creek, NC. We sampled a 100-m-long second-order site during both spring and autumn 1991–2004, using three-pass electrofishing. 2. Principle component analysis indicated that the site had lower average velocity, greater amounts of depositional substrata and lower amount of erosional substrata during the 1999–2002 drought than in non-drought years. In addition, drought years had lower flows, and lower variation in flows, than non-drought years. 3. Both young-of-the-year (YOY) and adult densities varied by an order of magnitude during the study. AIC analysis conducted on regressions of per capita rate of increase versus various population and habitat parameters for the population, adults and YOY, for both spring and autumn data sets, indicated that simple density dependence almost always was the only interpretable model with Akaike weights (wi) ranging from 0.262 to 0.836. 4. Growth analyses yielded more variable results, with simple density dependence being the only interpretable model for both adult spring data (wi = 0.999) and YOY autumn data (wi = 0.905), and positive density dependence (wi = 0.636) and simple density independence (wi = 0.241) representing interpretable models for spring YOY data. 5. We detected a significant stock–recruitment relationship between both spring and autumn densities of adults in year t and autumn YOY density in year t + 1. Finally, spring YOY density was positively correlated with both autumn YOY density and spring mean YOY standard length (SL), suggesting that processes affecting recruitment show residual effects at least in the first year of life. This population appears to be regulated primarily by density dependent processes, although high flows also negatively affected mean SLs of YOY.

File When are Genetic Methods Useful for Estimating Contemporary Abundance and Detecting Population Trends - Tallmon et al. 2010
This study assessed the ability of a linkage disequilibrium estimator of effective population size and a simple capture-recapture estimator of abundance to quantify the size and trend of stable or declining populations, using simulated Wright-Fisher populations.
