Description: See metadata (FGDC section) for complete information about this layer - https://landscape.blm.gov/COP_2010_metadata/COP_C_TI_4km_poly.xml This dataset provides an estimate of current terrestrial intactness, based on a fuzzy logic model that integrates multiple measures of landscape development and vegetation intactness. A powerpoint version of the logic model is available at: Vector\Conservation_Elements\Terrestrial\Ecosystem\Documentation\COP_TI_logic_models.pptx This model integrates agriculture development (from LANDFIRE EVT v1.1), urban development (from LANDFIRE EVT v1.1 and NLCD Impervious Surfaces), linear development (from BLM GTLF, utility lines, and pipelines), energy and mining development (from state mine and USGS national mines datasets as well as AZ uranium mines, geothermal wells, and oil/gas wells), invasive vegetation (multiple sources combined for invasives analyses in this REA), and measures of natural vegetation fragmentation calculated using FRAGSTATS. Terrestrial intactness is high in areas where development is low, vegetation intactness is high, and fragmentation is low. Caution is warranted in interpreting this dataset because it provides a single estimate of terrestrial intactness based on available data. The degree of terrestrial intactness likely varies for a particular species or conservation element, and may depend on additional factors or thresholds not included in this model. Instead, this model should be taken as a general measure of intactness that can serve as a template for evaluating across many species at the ecoregion scale, and provides a framework within which species-specific parameters can be incorporated for more detailed analyses. These data are provided by Bureau of Land Management (BLM) "as is" and may contain errors or omissions.

These data may not have the accuracy, resolution, completeness, timeliness, or other characteristics appropriate for applications that potential users of the data may contemplate.
