Freshwater Ecoregions, Northeast NOTE: This download link includes Fish Regions, Freshwater Ecoregions, and Freshwater Resilience. Freshwater ecoregions provide a global biogeographic regionalization of the Earth's freshwater biodiversity. These units are distinguished by patterns of native fish distribution resulting from large-scale geoclimatic processes and evolutionary history. The freshwater ecoregion boundaries generally, though not always, correspond with those of watersheds. Within individual ecoregions there will be turnover of species, such as when moving up or down a river system, but taken as a whole an ecoregion will typically have a distinct evolutionary history and/or suite of ecological processes (Abell et al. 2008). The WWF defined...

A value of 0.9 in a cell means that it has a resiliency score that is greater than 90% of all the cells of the same geophysical setting in that watershed, and all the cells with >0.9 values comprise the best 10% of all cells across all geophysical settings within the watershed. TNC's resiliency index, as scaled here, is a major component of the terrestrial core area selection index...

As such, great pains were taken to make this dataset as reflective of actual ground condition as possible. Each dataset used was evaluated at several locations, and multiple draft versions of the resistance surface were produced until reviewers were satisfied with the data.Each cell has been assigned a value, or weighting, representing it's hardness/ impermeability to species movement and ecological flows. Higher values are more difficult to cross, while lower values are easier. Natural lands are assigned a value of 1, meaning the cost to move across...

Connect the Connecticut is a collaborative effort to identify shared priorities for conserving the Connecticut River Watershed for future generations, considering the value of fish and wildlife species and the natural ecosystems they inhabit. Click here to download the full data package, including all documentation. This dataset identifies large and medium rivers within the Connecticut River watershed that provide habitat for five anadromous fish species: American shad, blueback herring, shortnose sturgeon, alewife, and sea lamprey. Habitat includes the mainstem and major tributaries of the Connecticut River...

Here, we posit that topoclimates provide species localized refugia from the direct effects of a changing climate, whereas landscape permeability reflects the ability of the landscape mosaic to facilitate terrestrial species movement to and between topoclimates as they shift in response to their respective climatic envelopes.90 m topoclimate data, scaled from 0.2 – 1, were multiplied with terrestrial landscape permeability data, scaled from 0 – 1, to generate a resilience value for every 90 m cell across the project area.

We developed methods to identify such a portfolio. First, we mapped geophysical settings across the entire study area. Second, within each geophysical setting we located sites with diverse topography that were highly connected by natural cover. Third, we compared the identified sites with the current network of conservation lands and with The Nature Conservancy’s (TNC’s) portfolio of important biodiversity sites identified based on rare species and natural community locations. Using this information we noted geophysical settings that were underrepresented...

Forest patches are defined as areas of contiguous natural cover bound by non-natural edge or linear fragmenting features (roads, railroads, transmission lines, natural gas pipelines). The following land cover types were selected from the 2006 National Land Cover Database (NLCD) to define “natural cover”: deciduous forest, coniferous forest, mixed [deciduous-coniferous] forest, scrub-shrub, woody wetland, and emergent wetland. Forest patches were delineated based on non-forest edge (from the NLCD) and the following linear fragmenting features:electric transmission lines (from...

Within each freshwater ecoregion, we defined one to four discrete fish regions using a cluster analysis of the USGS 8-digit Hydrologic Units (HUC) based on similarities in their native fish composition. The analysis was based on a previously developed list of native species present within each HUC (NatureServe, 2008). The cluster analysis defined up to four clusters within each freshwater ecoregion using similarity of composition (Linkage method: Flexible beta, Distance measure: Sorensen (Bray-Curtis), Flexible beta value of -0.250). To determine the faunal distinctiveness between clusters, we performed an indicator...
