These data represent general species distribution. At their most detailed, they depict species occurrence at a one square mile Section level. These data are based upon 1:100,000 scale Public Land Survey Section boundaries and are not intended to be used at finer scales. Due to this broad scale, these data are appropriate for general planning purposes or broad landscape review (e.g. watershed scale conservation planning). These data are not intended for planning and/or review of site-specific activities (e.g. reviewing subdivision proposals or energy development sites). For evaluating or reviewing site-specific applications Montana Fish, Wildlife & Parks (FWP) recommends contacting the appropriate FWP Regional office.

NOTE: Species distribution is not delineated within National Parks or Indian Reservations, as FWP does not have management authority in these areas.

Process step:
Historical distribution prior to 2007 was converted to distribution based upon Public Land Survey Section (PLSS). This was done by selecting those sections that intersected the species Use Type of General distribution and coding them as General. If required, this process was repeated for Winter distribution. The resulting Sections were then dissolved on Use Type to remove interior boundaries.
Process date: 12/31/2007
Process step:
Resulting PLSS based distribution was reviewed by area biologists to ensure accuracy and update changes.
Process date: 01/01/2008
Process step:
Resulting edits from biologists were incorporated and reviewed.
Process date: 08/08/2008
Process step: Final edits incorporated.

Attribute label: UseType
Attribute definition:
USE TYPES: Note: Species occur in areas of suitable habitats within their overall distribution, however not all areas will have animals or sign at all times every year. The specific areas occupied may expand or contract through time as seasons, population levels and habitat conditions change.

Definition of
Attribute Value
G General Distribution - Depicts areas predictably occupied by this species for part or all of its year-long range.
GW Winter Distribution - Depicts areas where populations of this species tend to concentrate during the winter season, commonly December through April. These areas are also considered part of the General Distribution. NOTE: Not all populations concentrate on specific ranges during the winter season. In areas where no winter distribution is delineated animals depend upon and occur across their General Distribution area during the winter season, or they may occur in localized concentrations that can not be depicted at the scale of these maps. Keep in mind that weather extremes can have a large influence on winter distribution in any given year.

Attribute label: Shape_Area
Attribute definition: Area of feature in internal units squared.

Attribute label: Shape_Leng
Attribute definition: Length of feature in internal units.
Attribute domain: Positive real numbers that are automatically generated.

Attribute label: OBJECTID
Attribute definition: Internal feature number.
