Redd (nest) surveys for resident brook trout (Salvelinus fontinalis) were conducted annually in a mountain lake in northern New York for 11 years with multiple surveys conducted during the spawning season in eight of those years. Elevated temperatures in summer were correlated with a delay in spawning and a reduction in the total number of redds constructed. Increasing the summer mean of maximum daily air temperatures by 1 °C delayed spawning by approximately 1 week and decreased the total number of redds constructed by nearly 65.

After more than a century of population decline resulting from habitat loss, and competition from invasive species, Brook Trout are starting to feel the heat from climate change as well. Fortunately, partners from all sectors are joining forces to tackle “the big three” with the right tools, using the best available science supported by the North Atlantic Landscape Conservation Cooperative, the Appalachian Landscape Conservation Cooperative, the EBTJV, and others.

This grant program is for the implementation of agricultural conservation practices that reduce or prevent negative impacts to the Commonwealth's natural resources that may result from agricultural practices, while maintaining sustainability and productivity of the agricultural operation. Part of this incentivizes producers to proactively address risks and strengthen their economic and environmental resiliency as they adapt to a changing climate. Agricultural operations engaged in production agriculture for commercial purposes as defined in Massachusetts law M.G.L c. 128, Sec. 1A. Applicant must own, or be a Co-Applicant with the owner of the agricultural operation.

Based on counts of Brook Trout (Salvelinus fontinalis) collected over 28 yr at 115 sites in Shenandoah National Park, we developed mixed-effects models to (1) assess how well extreme streamflow, as compared to mean flows and total precipitation, can explain young-of-the-year (YOY) abundance, (2) identify potential nonlinear relationships between seasonal environmental covariates and abundance using nonlinear generalized additive mixed models, and (3) explore likely impacts of expected future weather and streamflow conditions.
