Description: This dataset contains Management Area (MA) polygons on the Lolo National Forest. MAs represent specific criteria and constraints as described in the 1986 Lolo National Forest Plan chapters 2 and 3. The Lolo National Forest consists of 28 multiple-use management areas with a broad range of emphasis, intensities, practices, standards, and guidelines. The following approved MA amendments to the Forest Plan have been incorporated into this data set (amendments #4, 5a, 6, 7, 8, 13, 15, 17, 19, 20, 22, 29, 34, 35, 37, 42, 43 and 46). Old growth polygons from Superior North old growth analysis and INFISH RHCA polygon areas, which defines riparian acres, have been appended to this data set. Important Attributes: MA_CODE: numeric value of the MAMA_DESCRIPTION: a brief description of MA objective. VQO: Visual Quality Objective includes different degrees of excellence based on physical and sociological characteristics of an area.SUITABILITY: suitable/unsuitable for timber production.MA_CATEGORY: management area prescription categories and are used to display management area direction. The categories range along a continuum from little modification by humans to extensive use and modification by humans. Initially this dataset was developed using an Altek 3100 digitizer and overlay maps drawn on a scale of 1:24,000. The Forest Plan map which is a 1:126,720 map was used to identify Management Area 4. Digitizing from this map was also done when there was a discrepancy between the Forest Plan map and the overlays. Update 2021: Some portions of this dataset have been verttially alligned with the agency authorative surface ownership dataset produced by the Automated Lands Program (ALP). The ALP program is the process of updating the LSRS data for the Lolo NF to the latest version of the CadNSDI (digital PLSS data maintained by the State/BLM ). Vertical integration of the Management Area layer will continue once new LSRS data is published in the EDW.
Description: This dataset contains the Lolo National Forest Inventoried Roadless Areas (IRAs). IRAs are based on the completed Lolo NF forest plan (this information should be available in Appendix C of the forest plan). It has been dissolved by Inventoried Roadless Area Name to show only outside perimeter.
Description: Preliminary inventory of lands that may be suitable for recommendation to include in the National Wilderness Preservation System. Inclusion in the inventory is not a designation that conveys or requires a particular kind of management. These lands are documented, identified and are further evaluated in Step 2. Evaluate wilderness characteristics of inventoried lands for potential inclusion in the Wilderness Preservation System.
