This is a set of scripts developed by Madeline Steele in 2013 as a part of the Arid Lands Initiative (ALI) spatial prioritization analysis. They are provided here both as methodological documentation and because they may be useful for other projects. They are not set up to be imported into an ArcGIS toolbox, and all path names would have to be changed before they could be used. They are commented, and variables should be at the top, but they are probably not very useful without a bit of previous Python experience. Please feel free to use and/or splice and dice these scripts, and contact Madeline if you have any questions.

To support the ALI spatial priorities analysis, the LANDFIRE rasters in this geodatabase were downloaded from http://www.landfire.gov/datatool.php, and clipped to the Washington Wildlife Habitat Connectivity Working Group's (WHCWG) Columbia Plateau (CP) study area, which is the CP ecoregion with a 25km buffer. They were also projected to the HabConnectProjectArea_North_America_Albers_Equal_Area_Conic projection, a custom projection developed by the WHCWG for their CP analysis and also used for the ALI Marxan analysis. The data were downloaded in March 2013. Since then, some (but not all) of these datasets have been updated. The included layers are: - biophysical settings - succession class - existing vegetation...

A download link for the report and its appendices is below ("USFWS 2015 Assessing the Condition and Climate Resilience of Collaborative Conservation Priority Areas in the Columbia Plateau Ecoregion.pdf"). For those who don't need the appendices or who have a slow internet connection, a version with the report only is also provided ("USFWS 2015 Report only no appendices.pdf"). The scorecard appendix is also posted separately ("USFWS_2015_Appendix_A_PCA_Scorecards.pdf").Related Documents and Data:A companion report describing the Ecological Integrity Assessment and its results is here. An addendum report with scorecards and CCVA results for the ALI's Priority Linkage Areas (PLAs) is here (the report available on this...

After identifying collaborative conservation priority areas (see this report for details), the Arid Lands Initiative needed to assess the relative climate change vulnerability of these areas to better understand what management strategies might be most appropriate in each. This Climate Change Vulnerability Assessment (CCVA) for the ALI’s Priority Core Areas (PCAs) is fully described in this report. An addendum report, here, presents a complementary CCVA that was developed for the ALI’s Priority Linkage Areas (PLAs). PCAs were assessed relative to other PCAs, and PLAs relative to other PLAs, so they both have their own models attached below.

Ecoregions denote areas of general similarity in ecosystems and in the type, quality, and quantity of environmental resources. They are designed to serve as a spatial framework for the research, assessment, management, and monitoring of ecosystems and ecosystem components. These general purpose regions are critical for structuring and implementing ecosystem management strategies across federal agencies, state agencies, and nongovernment organizations that are responsible for different types of resources within the same geographical areas. The approach used to compile this map is based on the premise that ecological regions can be identified through the analysis of patterns of biotic and abiotic phenomena, including...

This file geodatabase includes the 2013 Land Use/Land Cover (LULC) and the Marxan target rasters that were derived from it. For an explanation of why targets were selected and how they were derived, please refer to the report. The Python scripts used to generate the layers are also available via the GNLCC portal.
