File D source code Mill Creek (Tygart River), WV: Large Woody Material Strategic “Chop and Drop”
Mostly dead and/or down hemlock trees were utilized to create large woody material inspired habitat structures to increase pool habit, increase thalweg meander length, decrease bankfull width, and introduce overhead fish cover. Cross-vanes, j-hooks, wing-deflectors, toe wood, digger logs, and engineered log jams were constructed. The strategic part of this chop and drop effort was to place and anchor logs to minimize movement in bankfull or high events.

File Octet Stream Dam Removals to Reconnect Brook Trout Habitat on an Unnamed Tributary to Frankstown Branch, Hollidaysburg PA
Kladder Dam was removed in September 2014 and the tributary through the former impoundment was restored to an appropriate gradient to match the watershed. Stream restoration materials included native soil and rock, clay from the dam’s core, sediment from behind the dam, and Large Wood Debris, all originating on the site. In addition, a riparian corridor was planted in the former impoundment, and several rock jack-dams and brick lining in about 100 feet of the stream channel above the former impoundment were removed by hand.

File ECMAScript program Predicting Brook Trout Occurrence in Stream Reaches throughout their Native Range in the Eastern United States
The Brook Trout Salvelinus fontinalis is an important species of conservation concern in the eastern USA. We developed a model to predict Brook Trout population status within individual stream reaches throughout the species’ native range in the eastern USA. We utilized hierarchical logistic regression with Bayesian estimation to predict Brook Trout occurrence probability, and we allowed slopes and intercepts to vary among ecological drainage units (EDUs). Model performance was similar for 7,327 training samples and 1,832 validation samples based on the area under the receiver operating curve (»0.78) and Cohen’s kappa statistic (0.44). Predicted water temperature had a strong negative effect on Brook Trout occurrence probability at the stream reach scale and was also negatively associated with the EDU average probability of Brook Trout occurrence (i.e., EDU-specific intercepts). The effect of soil permeability was positive but decreased as EDU mean soil permeability increased. Brook Trout were less likely to occur in stream reaches surrounded by agricultural or developed land cover, and an interaction suggested that agricultural land cover also resulted in an increased sensitivity to water temperature. Our model provides a further understanding of how Brook Trout are shaped by habitat characteristics in the region and yields maps of stream-reach-scale predictions, which together can be used to support ongoing conservation and management efforts. These decision support tools can be used to identify the extent of potentially suitable habitat, estimate historic habitat losses, and prioritize conservation efforts by selecting suitable stream reaches for a given action. Future work could extend the model to account for additional landscape or habitat characteristics, include biotic interactions, or estimate potential Brook Trout responses to climate and land use changes.
