A spatial representation of the general distribution of wild mountain sheep (bighorn and thinhorn sheep) in British Columbia. Populations that extend into neighbouring provinces and states are also included.

The distribution polygons are divided by species into bighorn and thinhorn sheep.

Data and Resources

Dataset Extent

Latitude: 48.0° to 60.0°
Longitude: -139.5° to -113.5°

Additional Information


The dataset was developed to coordinate and maintain the distribution of bighorn and thinhorn sheep in BC based on historical knowledge and population monitoring data.

This dataset is intended to:

  • document current distribution of wild sheep in BC;
  • support the development of science-based zones around wild sheep range to support a provincial regulatory framework that limits or excludes domestic sheep from high risk areas;
  • support awareness and monitoring of disease outbreaks that affect wild sheep across western North America; and
  • as an outreach and stewardship tool to help minimize the impacts of domestic sheep and goat farms adjacent to wild sheep populations and range.
Data Quality

The data does not include specific occurrence records of bighorn and thinhorn sheep in the province, rather it shows their generalized distribution.

  • There are no population estimates, abundance, or trend data associated with the spatial data;
  • There are no underlying ecological attributes; and
  • This dataset delineates currently occupied habitat, not the historical extent of sheep range in BC.
Lineage Statement

The dataset was built using core home range data and then generalized to include additional areas beyond the core use areas.

Object Description


Short Name: WM_SHP_DST
Comments: The public view of the BC Wild Mountain Sheep Registry indicates the general and broader distribution of bighorn and thinhorn (mountain) sheep distribution in British Columbia, beyond their core home ranges.

Column Name Short Name Data Type Data Precision Comments
WLD_WMSDS_SYSID WLD_WMSDSD NUMBER 10 WLD WMSDS SYSID is a system generated unique identification number.
SPECIES_COMMON_NAME COMMON_NM VARCHAR2 30 SPECIES COMMON NAME is the common name in English for the species e.g., Bighorn Sheep
SPECIES_SCIENTIFIC_NAME SCNTFIC_NM VARCHAR2 50 SPECIES SCIENTIFIC NAME is the scientific name for the species e.g., Ovis canadensis.
SPECIES_CODE SPECIES_CD VARCHAR2 10 SPECIES CODE is the 5-letter code for the species e.g. M-OVCA.
FEATURE_AREA_SQM AREA_SQM NUMBER 19 FEATURE AREA SQM is the system calculated area of a two-dimensional polygon in square meters.
FEATURE_LENGTH_M FEAT_LEN NUMBER 19 FEATURE LENGTH M is the system calculated length or perimeter of a geometry in meters.
SHAPE SHAPE SDO_GEOMETRY 1 SHAPE is the column used to reference the spatial coordinates defining the feature.
OBJECTID OBJECTID NUMBER 38 OBJECTID is a column required by spatial layers that interact with ESRI ArcSDE. It is populated with unique values automatically by SDE.
SE_ANNO_CAD_DATA BLOB 4000 SE ANNO CAD DATA is a binary column used by spatial tools to store annotation, curve features and CAD data when using the SDO GEOMETRY storage data type.
