Metadata elements shown with blue text are defined in the Federal Geographic Data Committee's (FGDC) Content Standard for Digital Geospatial Metadata (CSDGM). Elements shown with green text are defined in the ESRI Profile of the CSDGM. Elements shown with a green asterisk (*) will be automatically updated by ArcCatalog. ArcCatalog adds hints indicating which FGDC elements are mandatory; these are shown with gray text.
Soil Resource Inventory polygons containing basic information about soils on the Malheur National Forest.
The Soil Resource Inventory (SRI) has its primary use at the planning level. Soils, landforms and bedrock characteristics are defined at an intensity sufficient to help develop resource management policies and basic plans. Due to the reconnissance nature of this survey, it lacks detail for use in high-intensity, small-area projects. These projects require additional onsite study by various techical specialists, including soil scientists.
Does not contain the old Snow Mountain district.

Attribute data table built by Bill Gamble for all soils found on PCRD joined .dbf with .pat, renamed items, added Haz rating developed by Dave Kretzing and renamed haz item, Harv_disturb_haz, completed filling in erosion_pot item, added grazing_stability item calculated from erosion_pot item as per range folks.
Greg has since retired.
combined F04SRI and F04SRIOUT and identity with sws. This will replace the F04SRIHAZ, F04SRIOUT, and F04SRIHAZSWS.
P.O. Box 909
removed SWS lines from sri
Stacy is now with Burns BLM
changed item in pat slope_% to slope_pct so the RMET tool would run
P.O. Box 909
updated attributes as per Hersh McNeil, changing surf_erosion_pot from H to M-H
P.O. Box 909
converted to double precision
Clipped boundary with old Snow Mountain district to the LSP boundary line.
Reprojected to Region 6 Albers NAD83 projection
replaced the field surf_erosion_pot with new values contained in a dbf (converted to Info) table called new_ero.dbf at the request of Hersh McNeil. Joined the new table to the coverage, dropped the old surf_erosion_pot field, renamed the new_ero field back to surf_erosion_pot.
Changed the tolerances on all coverages to the malheur/bmprov default tolerances (most coverages didn't have them set:) fuzzy - .000123 dangle - 0 edit - 10.0 nodesnap - 2.0 weed - .02 grain - .02 snap - 2.0 Ran the aml &r comloop * cover &r tol ^

Depth of soil to bedrock, in inches
SRI MNF (1974)
Soil surface erosion potential
SRI MNF (1974)
Low - little loss of soil materials is expected. Some minor sheet and rill erosion may occur.
SRI MNF (1974)
Moderate - some loss of surface soil materials can be expected. Rill erosion and some sheet erosion may occur.
SRI MNF (1974)
High - considerable loss of surface soil materials can be expected. Rill erosion, numerous small gullies or evidence that considerable loss from sheet erosion may occur.
SRI MNF (1974)
Very high - large loss of surface soil material can be expected in the form of large losses from sheet erosion, numerous small gullies and rills or large gullies.
SRI MNF (1974)
Compaction potential - a relative prediction of soil behavior under the influence of foot, hoot, vehicular or log traffic
SRI MNF (1974)
Low - factors indicate that detrimental compaction will be a minor problem.
SRI MNF (1974)
Moderate - factors indicate that compaction will be a problem in the spring and early summer.
SRI MNF (1974)
High - factors indicate that compaction will be a problem for a large part of the spring and summer.
SRI MNF (1974)
Displacement potential - a rating of the ease with which soil material can be loosened and moved after its vegetation and litter are removed.
SRI MNF (1974)
Low - factors indicate that these soils are not easy to loosen and/or displace.
SRI MNF (1974)
Moderate - factors indicate that these soils are moderately easy to loosen and/or displace.
SRI MNF (1974)
High - factors indicate these soils are easy to loosen and/or displace.
SRI MNF (1974)
Puddling potential - the act of destroying soil structure when it is in a wet and plastic condition.

Natural stability - a rating based on the relative stability of the mapping units as they occur in the natural state.
SRI MNF (1974)
Very stable - no evidence of failure.
SRI MNF (1974)
Stable - occasional failures are observed.
SRI MNF (1974)
