These data represent a potential Conservation Target for the Working Lands Priority Resource of the PFLCC. The potential Conservation Target is the connectivity of Working Lands. The Florida Greenways layer from CLIP 4.0 provides a context for Connectivity with natural habitats that provide connections between large natural areas in Florida. For additional metadata on CLIP 4.0, see the gallery of the same name in the Peninsular Florida LCC Community. The data set shown depicts the Greenways priorities within the Working Lands Priority Resource only. The Working Lands Priority Resource raster layer was used as a mask to extract the Greenways priority values for pattern analysis.

In the Southeast, where rapid human development is increasingly dividing natural areas, habitat fragmentation and loss threaten the health and even genetic viability of wildlife populations, and interrupt migration routes. Climate change is projected to exacerbate fragmentation by further disrupting landscapes. To make matters worse, it is also expected to shift the range of many species, forcing animals capable of adapting by moving to expand into new areas to find more suitable temperatures and adequate food supplies – a challenge made difficult, if not impossible, by disconnected landscapes. Maintaining connectivity between habitats is a key strategy for conserving wildlife populations into the future, and sound...
The Washington Connected Landscapes Project is a highly leveraged effort to provide scientific analyses and tools necessary to conserve wildlife habitat connectivity. In support of the project, we 1) developed tools necessary to reliably identify and prioritize areas important for connectivity conservation and restoration under current conditions and for allowing species range shifts under climate change; 2) tested and refined these tools by applying them in a Great Northern LCC (GNLCC)-funded effort to identify essential habitats and linkages for the Columbia Plateau Ecoregion where the WHCWG is currently engaged (connectivity and climate tools) and across Washington State (climate tools); and 3) released these...
Conclusions: Assessments of metapopulation structure must consider landscape pattern, but also the non-linear responses of organisms to such patterns Thresholds/Learnings: Synopsis: This study used beetles to empirically test the reliability of neutral percolation models to predict critical thresholds of landscape connectivity. Beetle movements declined sharply when grass cover dropped below 20% of the experimental plot. The findings of this study differed from what was predicted by the model, indicating that landscape connectivity is not dependent on spatial pattern alone, but is also highly dependent how individual organisms move within and among patches depending on the amount of cover. The results suggest that...
We attempted a complete review of the empirical literature on effects of roads and traffic on animal abundance and distribution. We found 79 studies, with results for 131 species and 30 species groups. Overall, the number of documented negative effects of roads on animal abundance outnumbered the number of positive effects by a factor of 5; 114 responses were negative, 22 were positive, and 56 showed no effect. Amphibians and reptiles tended to show negative effects. Birds showed mainly negative or no effects, with a few positive effects for some small birds and for vultures. Small mammals generally showed either positive effects or no effect, mid-sized mammals showed either negative effects or no effect, and large...

This project was funded to understand how, where, and why outputs from landscape connectivity models vary, and to suggest approaches to increase comparability and interoperability of models across Landscape Conservation Cooperative boundaries. We began by compiling metadata from 73 landscape connectivity modeling projects into an online, editable spreadsheet. Using spatial data from a subset of studies included in the database, we conducted an uncertainty analysis to understand how much spatial variation there was among predictions from different landscape connectivity models. Raw outputs from the original models showed relatively little overlap, averaging about 3% across all pairs of studies. However, when a common...

University of Arizona will conduct an ecosystem conservation assessment for the lower San Pedro (LSP) watershed. The assessment will provide a science-based strategic design for prioritizing where conservation efforts are most needed for high-value biodiversity conservation at the landscape-level and offer insights on conservation actions practical for implementation. The assessment will include an evaluation of high-value biodiversity, hydro-ecological processes, protected areas, landscape connectivity, and climate change adaptation. The study will suggest approaches for developing a new conservation framework for watershed conservation planning.
