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...

This is an aggregate national dataset describing the geographic boundaries of the ACEC within the BLM managed public lands. The designated ACECs are "areas within the public lands where special management attention is required to protect and prevent irreparable damage to important historic, cultural, or scenic values, fish and wildlife resources or other natural systems of processes, or to protect life and safety from natural hazards." To include information on Ownership and Level of Protection (CEA Technical Team decision, 6/1/12), Intersect the PAD-US dataset (PADUS_1_2_StudyArea) with the NM_NCA_and_Similar data with the following fields turned on: Owner Type, Owner Name, Local Owner, Manager Name, Primary Designation...

This dataset is an extraction from PAD-US 1.1 of BLM ACECs in the Tehachapi study area that are designated species habitat. This dataset is an extraction from PAD-US 1.1 (CBI Edition), by state.The PAD-US 1.1 (CBI Edition) data set portrays the nation's protectedareas with a standardized spatial geometry and numerous valuableattributes on land ownership, management designations, and conservationstatus (using national GAP and international IUCN coding systems). ThePAD-US 1.1 (CBI Edition) defines protected areas to include all landsdedicated to the preservation of biological diversity and to othernatural, recreation and cultural uses, and managed for these purposesthrough legal or other effective means (adapted from...

This coverage dataset represents the existing Bureau of Land Management (BLM) Areas of Critical Environmental Concern (ACEC) in California. Areas of critical environmental concern are designated by the BLM under the requirements of the Federal Land Policy and Management Act (FLPMA). This designation depicts areas where special management attention is required to prevent significant damage to important ecological and cultural resources, or due to natural hazards that require special management. Special management practices are defined for these areas through the BLM's land management planning process. Areas of critical environmental concern are nominated by individuals or organizations within or outside the BLM....

This polygon feature class shows the spatial extent and boundaries of Areas of Critical Environmental Concern that have become officially designated by the BLM. These polygon features were previously in a pre-designated status (i.e. being considered as areas to be eventually designated as official ACEC designated polygonst). Once these polygon feature left the Pre-Designated phase (transitioned from a Considered to Designated status), they were removed from the ACEC Pre-designated polygon feature class and placed in this ACEC Designated polygon feature class. This dataset is a subset of the official national dataset, containing features and attributes intended for public release and has been optimized for online...

This dataset depicts the distribution of primary and secondary areas of critical environmental concern, research natural areas, and outstanding natural areas on Bureau of Land Management (BLM) lands in Oregon and Washington. The area type and managed value are represented by attributes defined within the metadata. Areas of critical environmental concern are designated by the BLM under the requirements of the Federal Land Policy and Management Act (FLPMA). This designation depicts areas where special management attention is required to prevent significant damage to important ecological and cultural resources, or due to natural hazards that require special management. Special management practices are defined for these...

Once a polygon feature leaves the Pre-designated phase (transitions from Considered to Designated), that polygon will be removed from the ACEC Pre-designated feature class and be placed in the ACEC Designated feature class. This data set consist of digital data describing (ACEC) Areas of Critical and Environmental Concern for Public Lands in the State of Colorado. ACECs are designated by decisions made during BLM Resource Management Planning. Existing ACECs have a Resouce value tied to them. An example of these resources would be: Threatened and Endangered Plants. Other areas of concern have also been captured within this theme. When the users opens up the attribute table for this theme the user will notice ACEC...
