Title: BLM GRSG BER: Areas of Critical Environmental Concern (ACEC) - Protected Areas Database Categories 1, 2 and Unknown (polygon)
Geospatial Data Presentation Form: vector digital data
Online Linkage: https://gis.blm.gov/BER_LayerPackages/ACEC_PAD_Cats_1_2_unk.lpk
Description:
Abstract: 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 Type, Primary Local Designation Type, Primary Local Name, GAP Status Code, and GAP Status Code Desc. Used Eliminate to remove slivers created from the intersect showing "Unknown" PAD-US designations. Checked visually to preserve those large areas that were likely real "Unknown" designations due to lack of the area in PAD-US.Gap Status Code Attributes: Unknown = Unknown 1 = An area having permanent protection from conversion of natural land cover and a mandated management plan in operation to maintain a natural state within which disturbance events (of natural type, frequency, intensity, and legacy) are allowed to proceed without interference or are mimicked through management. 2 = An area having permanent protection from conversion of natural land cover and a mandated management plan in operation to maintain a primarily natural state, but which may receive uses or management practices that degrade the quality of existing natural communities, including suppression of natural disturbance.
Purpose: GSSP SNAPSHOT of Approved data set made on 5/14/12 for the Greater Sage-grouse baseline rangewide cumulative effects analysis. Modified for the GRSG CEA analysis effort by including PAD-US GAP_STATUS_CODEs to determine level of protection and selecting only those equal to 1 or 2. Approved by CEA Technical Team decision, 6/1/12.These data are used when making management decisions and are intended to assist in the protection of the resources the ACEC was designated to protect. It documents where ACECs are located.

Attribute:
Attribute Label: CASEFILE_NO
Attribute Definition: The number that refers to the serialized case file number of the group of official documents that record the facts, or actions taken, on a specific application, such as an oil and gas lease, exchange, airport lease, easement acquisition, etc. (CMR). This field should be in uppercase (for example, OR035582). This is a BLM International Organization for Standardization (ISO) assigned number used for identification of all lands and minerals case files including ACECs. This is the link to the LR2000 database. N/A - Not Applicable is the default code and will be used when no casefile number has been assigned. A value of "UNK" indicates unknown.
Attribute:
Attribute Label: ACEC_EST_ACR
Attribute Definition: The measure of the area estimated in the designation process for land use planning. This is the designated size (acres) and may be different than the actual area. This does not change. Acres are calculated using the following formula: [Acres = Area (in meters)/4046.87]. This may be different than the GIS calculated area of the ACEC polygon. This field value should be the same for each polygon in an ACEC comprised of multiple polygons. The values in this field do not change. Do not use this field to derive GIS acres.

Attribute Definition: The date on which the decision is signed by the person who has approval authority for the decisions. The ROD signing date of the monitoring or activity plan, if any, for the particular ACEC. The date will be in the format of MM/DD/YYYY.
Attribute:
Attribute Label: GIS_ACRES
Attribute Definition: This is a calculated value of area in units of acres based on the area field created by default within the ESRI Polygon data structure. For the purposes of a 'national data layer', the data are to be stored in geographic coordinates which do not correspond to ground values. This requires that there be a standard method for calculating this attribute. The method used for these data are as follows: The data are projected into a standard projection such as the ESRI default Albers projection for the continental United States, "US Albers NAD 1983." Once the data are projected, then a calculation of "SHAPE_Area (square meters) * 0.0002471044 = acres" is applied to the existing 'area' field that is default area created by the ESRI software resulting in the field (Attribute) 'SHAPE_Area'. Please note that the figure used in this calculation is the factor for converting the US Survey Foot value of for the length of a meter as opposed to the International Standard for converting meters and feet.
Attribute:
Attribute Label: ADMIN_ST
Attribute Definition: An administrative unit that identifies the state or geographic area which has administrative jurisdiction over lands, and cases, although the land for a case may not be physically located in a state. Only those states that are BLM administrative states are in the domain for this entity.

This field enables users to search for a protected area by name, regardless of how many parcels it contains but can be concatenated with the Primary Designation Type field. The Primary Local Name field, from the data source, is calculated into this field and standardized. In previous PAD-US versions the designation type was included. This field is in transition to the updated standard.
Attribute:
Attribute Label: P_Loc_Nm
Attribute Definition: The name of the protected area as provided by the data source not standardized for the US. As a result, this field may include designations, different formats, spelling errors, unit or area identifiers unique to parcels but joins to source data files.
Attribute:
Attribute Label: GAP_Status_Code
Attribute Definition: The GAP Status Code is a measure of management intent to conserve biodiversity defined as: Status 1: An area having permanent protection from conversion of natural land cover and a mandated management plan in operation to maintain a natural state within which disturbance events (of natural type, frequency, intensity, and legacy) are allowed to proceed without interference or are mimicked through management. Status 2: An area having permanent protection from conversion of natural land cover and a mandated management plan in operation to maintain a primarily natural state, but which may receive uses or management practices that degrade the quality of existing natural communities, including suppression of natural disturbance. Status 3: An area having permanent protection from conversion of natural land cover for the majority of the area, but subject to extractive uses of either a broad, low-intensity type (e.g., logging, OHV recreation) or localized intense type (e.g., mining). It also confers protection to federally listed endangered and threatened species throughout the area. Status 4: There are no known public or private institutional mandates or legally recognized easements or deed restrictions held by the managing entity to prevent conversion of natural habitat types to anthropogenic habitat types. The area generally allows conversion to unnatural land cover throughout or management intent is unknown. See the PADUS Standards Manual for a summary of methods.
