North America Grassland PCAs 2010 This data set shows the grasslands priority conservation areas (GPCAs) within North America’s Central Grasslands, an ecosystem considered among the most threatened in the continent and the world. GPCAs are defined as areas of tri-national importance due to their ecological significance and threatened nature, which are in need of international cooperation for their successful conservation. The 59 GPCAs were identified by biodiversity experts through research and a workshop co-organized by the Commission for Environmental Cooperation (CEC) and the Nature Conservancy in 2004 and Rocky Mountain Bird Observatory in 2010. This is an amended version of the 2007 data set.

The index uses the maximum normalized difference vegetation index (NDVI) for early season greenness (January-June), and mean NDVI (July-October) for the later dry season. We estimated the relative cover of invasive annuals each year at turbine locations and control sites and tested for changes before and after each turbine was installed. These data were used...

It incorporates landscape and management unit features to help prioritize management on 17 oak savanna and open woodland restoration and enhancement project areas. The private lands program and other stakeholders can use this information to prioritize and target management. This shapefile contains the relevant input criteria attributes used in the development of station objective models.
