This raster dataset represents Places II: Specially Designated Areas of Ecological and Cultural Value within the Mojave Basin and Range. These sites represent legally protected lands and waters. Plus lands that have been identified as known recovery lands (e.g. critical habitat recommended for recovery of Desert Tortoise and recovery units identified for the CA red legged frog).

This simple assessment raster is used to answer management questions (MQs) about where change agents (CAs) overlap with BLM high biodiversity sites (HBS) in the Central Great Basin and Range Ecoregion. This is a basic footprint assessment of anthropogenic features (urban development, roads, etc) intersect with the areas of HBS. The HBS were derived from source data characterizing locations with concentrated at-risk biodiversity or existing source data of a prioritization exercise that identified areas of high conservation significance. It does not model actual response or condition of the HBS to the CAs. The data intersects two primary classes of information: The CAs consist of 19 classes which represent different...

This simple assessment layer is used to answer management questions (MQs) about which high biodiversity sites (HBS) will experience significant climate change in the near future scenario in the Mojave Basin and Range Ecoregion. This is a basic intersect of areas that will likely experience significant climate change effects with the areas that have been identified by previous 3rd party analyses as having extraordinary biodiversity. It does not model actual response or condition of the HBS to climate change. Nearly all HBS in the ecoregion will experience significant effects according to the criteria that were selected. The climate space trends data layer was used to ascertain areas of significant climate changes....

A region polygon dataset categorizing land in terms of ecological significance and status of protection in the Central Basin and Range (CBR) Rapid Ecoregional Assessment. This dataset identifies lands that have been identified as ecologically significant to biodiveristy but not yet legally protected (Places I - Sites of High Biodiversity), lands that have some type of protection status, often federal or state (Places II - Specially Designated Areas of Ecological and/or Cultural Value), and lands that may be ecologically significant but are managed for multiple use (Places III – Other Managed Lands).

This raster is used to answer management questions (MQs) about where conservation elements (CEs) overlap with areas of high wind energy potential in the Mojave Basin and Range Ecoregion. The value indicated in the raster represents a normalized score between 0-1, the lower the value the few species and poorer modeled landscape condition (ecological integrity) expected. The higher the score, the more species and higher condition are expected. This layer seeks to address an article in the BLM Statement of Work 1.1.1 stated, Areas with High Potential for Renewable Energy Development (Required) (The Contractor shall a) locate areas identified (e.g., by DOE, USGS) as suitable for wind, solar, geothermal, and biomass...

This simple assessment raster is used to answer management questions (MQs) about where change agents (CAs) overlap with BLM Herd Management Areas (HMAs) in the Central Great Basin and Range Ecoregion. This is a basic footprint assessment of anthropogenic features (urban development, roads, etc) intersect with areas managed for wild horses and burros in the western US. It does not model actual response or condition of the HMAs to the CAs. The data intersects two primary classes of information: The CAs consist of 19 classes which represent different types of human infrastructure on the landscape. Some types are easily defined, precise footprints (pipelines, roads, energy development areas) while others are broader...

This simple assessment raster is used to answer management questions (MQs) about which grazing allotments (GAs) will experience significant climate change in the near future scenario in the Mojave Basin and Range Ecoregion. This is a basic intersect of areas that will likely experience significant climate change effects with the areas of public land that are leased to private entities for grazing by livestock. It does not model actual response or condition of the GAs to climate change. Nearly all GAs in the ecoregion will experience significant effects according to the criteria that were selected. The climate space trends data layer was used to ascertain areas of significant climate changes. Cells that represent...

This is a basic intersect of areas that will likely experience significant climate change effects with the areas of public land that managed for wild herds of horses and/or burros. It does not model actual response or condition of the HMAs to climate change. Nearly all HMAs in the ecoregion will experience significant effects according to the criteria that were selected. The climate space trends data layer was used to ascertain areas of significant climate changes. Cells that represent Near...

ACECs are areas where special management is needed to protect important historical, cultural, or scenic values, fish and wildlife resources, or other natural systems or processes, or to identify areas hazardous to human life and property. Criteria for ACECs can be found at: BLM Manual 1613 and 43 CFR 1610.7-2(b). RNAs are areas where natural processes are allowed to predominate and which is preserved for the primary purposes of research and education. Under current BLM policy, RNAs must meet the relevance and importance criteria of ACECs and are designated as ACECs. Criteria for RNAs can be found at: BLM Manual 1613 and 43 CFR 1610.7-2(b). ONAs are areas with high scenic values that have been little altered by human...

The Protected Areas Database of the United States (PAD-US) is a geodatabase that illustrates and describes public land ownership, management and conservation lands nationally, including voluntarily provided privately protected areas. The lands included in PAD-US are assigned conservation measures that qualify their intent to manage lands for the preservation of biological diversity and to other natural, recreational and cultural uses; managed for these purposes through legal or other effective means. The geodatabase includes: 1) Geographic boundaries of public land ownership and voluntarily provided private conservation lands (e.g., Nature Conservancy Preserves); 2) The combination land owner, land manager, management...

A region polygon dataset categorizing land in terms of ecological significance and status of protection in the Mojave Basin and Range (MBR) Rapid Ecoregional Assessment. This dataset identifies lands that have been identified as ecologically significant to biodiveristy but not yet legally protected (Places I - Sites of High Biodiversity), lands that have some type of protection status, often federal or state (Places II - Specially Designated Areas of Ecological and/or Cultural Value), and lands that may be ecologically significant but are managed for multiple use (Places III – Other Managed Lands).

This raster dataset represents Places I: Sites of High Biodiversity within the Central Basin and Range. Areas of High Biodiversity were derived from source data characterizing locations with concentrated at-risk biodiversity or existing source data of a prioritization exercise that identified areas of high conservation significance.

This layer represents areas that have been designated by the states of California and Nevada and the Arizona BLM as priority zones for development for renewable energy int the Mojave Basin and Range Ecoregion. These layers were assembled from three sources: Nevada Renewable Energy and Proposed Interconnections Map. Gov. Jim Gibbons Nevada Renewable Energy and Transmission Access Advisory Committee, Phase II Report. June 26, 2009; California Renewable Energy Transmission Initiative (RETI). Phase 2B Maps (CREZ and Transmission Line Sebments Revised to Reflect Phase 2B). April 8, 2010; AZ REDA Alternative 1 (Maximum REDA, Areas identified during the RDEP alternatives development process). Arizona BLM State Office....

It is important to note that just because an area has high mineral potential does not mean it will be developed. There are several factors that go into starting up a mining endeavor. Also areas with high mineral potential inside protected areas are not likely to be developed.

This raster is used to answer management questions (MQs) about where conservation elements (CEs) overlap with the total potential renewable energy footprint in the Central Basin and Range Ecoregion. While this assessment suggests the potential for large numbers of CEs and large areas of habitat to be impacted, only a small proportion of the total potential is expected to be developed.
