Abstract:

These data cover designated National Wildlife Refuges (NWRs) in Montana.

They are extracted from the statewide land ownership and managed areas layer maintained by the MTNHP. Only the outer Refuge boundary is included here. Many refuges contain "inholdings" that are not owned by the US Fish and Wildlife Service (USFWS); but these inholdings have been deleted from this data set to simplify the representation of these areas.

The name of each Refuge is provided in the NAME attribute field.

Data Quality Information:

Attribute accuracy report:

Refuge names are from the US Fish and Wildlife Service. See: http://www.r6.fws.gov/refuges/mt/

Horizontal Positional Accuracy Report:

This is basically 1:100000 scale (100K) data with a horizontal accuracy of approximately 170 feet.

Title: Land ownership and managed areas in Montana
Source scale denominator: 100000
Source contribution: The data set is a subset of stew.
Beginning date: 2000
Ending date: 08/28/2002

Process step:

Arcs for polygons with OWN = 13 are copied from stew to this layer and are unsplit. Polygons representing inholdings (non-USFWS lands wholly within a Refuge Boundary) are deleted. Then labels are added and coded with the Refuge name.
