Conclusions: Successional changes resulting from a legacy of fire suppression and other agricultural and access disturbances combine to create the current hetergeneous landscape mosaic. Thresholds/Learnings: Synopsis: Disturbance is considered to be a major factor influencing landscape pattern and vegetation composition. However, the presettlement vegetation composition of three Ohio (U.S.A) counties was controlled largely by soil texture, soil drainage, and topography. In most cases, both disturbance regime and local site conditions can explain presettlement landscape pattern. This study examines the roles of edaphic conditions landscape features such as topography, and fire in contributing to (1) the abundance,...
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...

NPScape landscape pattern metrics are calculated for particular land cover types using NPScape land cover metric GIS data. The methods underlying these calculations are available for download through the NPScape website: http://science.nature.nps.gov/im/monitor/npscape/methods.cfm. This record provides default metadata for metric GIS data developed and distributed by NPScape. More information and updates are available through the NPScape website: http://science.nature.nps.gov/im/monitor/npscape/.

Wind energy generation causes transformation of landscapes as new roads, pads, and transmission lines are constructed. We mapped, quantified, and analyzed the effects of facilities' geographic context on road networks and changes in landscape patterns by digitizing the footprints of 39 wind facilities and the surrounding land cover using high-resolution imagery of before and after construction. These data were used in understanding how new facilities change the amount of undeveloped land and changes in metrics of landscape patterns.
Synopsis: This book is the foundational text for understanding landscape ecology in terms of pattern/process relationships. Forman introduces the concept of “indispensible patterns” of habitat and habitat linkages that, if protected, can conserve the majority of important ecological function in a landscape. While all or specific attributes of an ecosystem may not be protected by these measures, the most important assets will retain their integrity if the essential general patterns are maintained. Forman’s Indispensable Landscape Patterns are related to both configuration and connectivity and fragmentation (figure 1). Forman suggests that the following patterns are indispensable in maintaining an ecologically viable...
