Description: This metadata record describes a shapefile depicting Nebraska's Biologically Unique Landscapes (BULs) as identified in conjunction with the development of a comprehensive wildlife conservation plan (Schneider et al 2005, aka the Natural Legacy Plan, and its subsequent revision in 2010/2011) for the state. The following summary of how BULs were defined is copied directly from Chapter 3, page 15 of that Schneider et al 2005: "One of the goals of the Natural Legacy Project is to identify a set of priority landscapes that, if properly managed, would conserve the majority of Nebraska's biological diversity. These landscapes, which we are calling Biologically Unique Landscapes, were selected based on known occurrences of at-risk species and ecological communities. In addition to at-risk species, these landscapes support a broad array of common species. The following sections describe the approach we used to identify the at-risk species, ecological communities and biologically unique landscapes." Initial efforts to implement the Natural Legacy Plan focused on nine Biologically Unique Landscapes (BULs) that had 'Flagship Initiatives' underway. Flagship Initiatives are coordinated efforts that include conservation actions on private and public lands, education and outreach, and monitoring and research. As part of the revision of the Natural Legacy Plan in 2010, six boundaries were modified. The changes were approved in 2011.

Copyright Text: Groundwater Elevation data:
This grid represents the groundwater level elevation surface for the alluvial aquifer of the SPDSS study area. The groundwater level elevation values were obtained from historical groundwater reports and other data sources evaluated in the SPDSS Phase 3 Task 42.3 TM. The data were merged together, modified where necessary, exploded to points, and then gridded. Data set was created in 2005.
