- Description:
- Abstract:
- 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 follows most of names for each area. Some BLM field offices also included RNAs and ONAs with in their layer. ONAs are... Outstanding Natural Areas and RNAs are... Research Natural Area
The data set was compiled from the most current data collected from the BLM Colorado Field Offices. In some cases data boundaries were snapped to BLMs Geographic Coordinate Data Base (GCDB). The GCDB is a statewide survey grid that BLM bases land boundaries on. Also in some cases within the ACECs outer boundary land holdings other than BLM have been cut out to show these Land Patterns, In other cases it has not. It is suggeted that the user of this data also download BLMs most current Land Ownership Layer to compare and contrast land holdings within each ACEC.
- Purpose:
- To illustrate Areas of Critical and Environmental Concern (ACEC) for the State of Colorado and for BLM (RMP) Resource Management Plan analysis and decision making.
- Supplemental_Information:
- Original data was located at each BLM Field Office in Colorado. GIS specialist at BLM Colorado State Office (CSO) quality checked data and Merged the individual Arcinfo "layers" into the a Statewide layer.

- Process_Step:
- Process_Description:
- Individual 24K coverages merged into Statewide coverage (QA and QC applied). Some data edits occured on the original arcinfo "coverages". The ACEC polygon coverage located in the BLM Royal Gorge RA had many dangle and label errors when received at the State Office. These errors were cleaned up at the State Office before mapjoin.
- Process_Date: 19980816
- Process_Step:
- Process_Description:
- Coverage converted into a Arcview Shapefile. Updated ACECs boundaries were collected from BLM Colorado Field Offices in various formats. The old data was combined with the new data sources to produce a new and better representation of ACECs as of May 2006.
