Science Seminar Series - Patch Metrics, Wild Brook Trout, and the Chesapeake Bay by Web Editor, last updated: Jul 24, 2012 10:28 AM
The wild brook trout resource in the Chesapeake Bay has been significantly reduced over the last 150 years and faces ongoing and future threats from climate change, land use changes, invasive species and loss of genetic integrity (Hudy et al. 2008). Monitoring both short and long term trends on individual brook trout (Salvelinus fontinalis) populations and the resource as a whole are important needs of managers. Past assessments on the 1,443 subwatersheds in the Chesapeake Bay found that 226 had healthy brook trout (intact); 542 had reduced populations and 290 were extirpated (Hudy et al. 2008). However, the subwatershed scale assessment was not fine scale enough to efficiently monitor trends on the ground of interest to many mangers. Standard population estimates using mark-recapture and depletion removal estimates are also not viable for large scale monitoring because of expense, inability to detect trend (i.e. large coefficient in variation), and problems expanding the sample to the entire population. However, fine scale occupancy data (at the catchment level) exist for the majority of the brook trout resource in the Chesapeake Bay. Currently (not counting New York, not completed yet), there are 3,003 catchments containing allopatric brook trout populations; 1,716 catchments containing sympatric populations (with brown or rainbow trout); and 1,966 catchments containing only exotic trout species. We used this fine scale catchment data to identify unique patches of brook trout. We define a "patch" as a group of contiguous catchments occupied by wild brook trout. Patches are not connected physically (separated by a dam, unoccupied warm water habitat, downstream invasive species, etc) and are generally assumed to be genetically isolated. In the Chesapeake Bay there are 868 patches of brook trout habitat with an average patch size of 2,800 ha.

Wildlife Conservation Society Conservation Challenges - Climate Change by Web Editor, last updated: Mar 30, 2012 06:33 PM
Climate change is arguably the pre-eminent challenge facing the conservation of wildlife and wild places. The WCS North America Program is addressing this challenge to ensure the long-term success of our conservation efforts. Warming has already begun to affect wildlife by shifting species’ ranges, altering the timing of seasonal events, decreasing snowpacks and streamflows, increasing lake and stream water temperatures, and melting glaciers and sea ice. As North America and the rest of the planet continue to warm, the conservation of diminishing water sources will likely become a major focus for local communities and public land managers. Other anticipated changes include the expansion of severe wildfires, increased drought frequency and severity, increased plant and wildlife disease outbreaks and insect infestations, and the degradation of vulnerable habitats, all with major implications for wildlife. There is a growing need for conservation actions now to help offset inevitable changes in landscapes and wildlife populations.

U.S. Fish and Wildlife Service Climate Change Strategy - Rising to the Urgent Challenge: Strategic Plan for Responding to Accelerating Climate Change by Web Editor, last updated: Mar 30, 2012 03:10 PM
The U.S. Fish and Wildlife Service climate change strategy, titled “Rising to the Urgent Challenge: Strategic Plan for Responding to Accelerating Climate Change,” establishes a basic framework within which the Service will work as part of the larger conservation community to help ensure the sustainability of fish, wildlife, plants and habitats in the face of accelerating climate change. The plan is implemented through a dynamic action plan that details specific steps the Service will take during the next five years to implement the Strategic Plan.
