Woodland caribou habitat potential within the provincial forest of central and northern Saskatchewan has been identified by Saskatchewan, using a forest ecosite geographic information system layer which has been mapped for the area. Forest ecosites represent information about a site\u2019s tree species, plant-abundance and soil and site characteristics (McLaughlan et al., 2010). Forest ecosite habitat potential ranks were assigned by individually evaluating the ecosite\u2019s potential to provide forage, refuge and calving habitat. <\/SPAN><\/P>

Forage value was rated based on the availability of lichen and other plant species, which are palatable to caribou (Thomas and Armbruster, 1996).<\/SPAN><\/P>

Refuge value was rated based on the availability of plant species which provide food value for other ungulates (e.g. moose, deer, elk). This was used as a surrogate for the probability of predation. If these food sources are not present, the ecosite has potential to provide refuge for caribou from predators. <\/SPAN><\/P>

Calving and post-calving ratings were made in consideration of both the time of calving and the following two to four-week period. The primary consideration was safety from predation. The related factors considered were the ability to hide a calf and the lack of spring black bear forage. A secondary consideration was whether there was caribou forage available on the site.<\/SPAN><\/P>

Ecosite rankings were completed by a panel of biologists with expertise on woodland caribou habitat use in Saskatchewan. Forest ecosites were mapped with the assigned habitat potential value.<\/SPAN><\/P><\/DIV><\/DIV><\/DIV>", "geometryType": null, "copyrightText": "Lands Branch, Ministry of Environment", "parentLayer": null, "subLayers": [ { "id": 1, "name": "Boundary" }, { "id": -1, "name": "" }, { "id": 3, "name": "Image" } ], "minScale": 0, "maxScale": 0, "defaultVisibility": true, "extent": { "xmin": 134000, "ymin": 5427000.816, "xmax": 766020, "ymax": 6661910.816, "spatialReference": { "wkt": "PROJCS[\"North_American_1983_CSRS_UTM_Zone_13N\",GEOGCS[\"GCS_North_American_1983_CSRS\",DATUM[\"D_North_American_1983_CSRS\",SPHEROID[\"GRS_1980\",6378137.0,298.257222101]],PRIMEM[\"Greenwich\",0.0],UNIT[\"Degree\",0.0174532925199433]],PROJECTION[\"Transverse_Mercator\"],PARAMETER[\"False_Easting\",500000.0],PARAMETER[\"False_Northing\",0.0],PARAMETER[\"Central_Meridian\",-105.0],PARAMETER[\"Scale_Factor\",0.9996],PARAMETER[\"Latitude_Of_Origin\",0.0],UNIT[\"Meter\",1.0]]", "xyTolerance": 0.001, "zTolerance": 0.001, "mTolerance": 0.001, "falseX": -5120900, "falseY": -9998100, "xyUnits": 10000, "falseZ": -100000, "zUnits": 10000, "falseM": -100000, "mUnits": 10000 } }, "hasAttachments": false, "htmlPopupType": "esriServerHTMLPopupTypeNone", "displayField": "", "typeIdField": null, "subtypeFieldName": null, "subtypeField": null, "defaultSubtypeCode": null, "fields": null, "geometryField": {}, "indexes": [], "subtypes": [], "relationships": [], "canModifyLayer": false, "canScaleSymbols": false, "hasLabels": false, "capabilities": "Query,Map", "supportsStatistics": false, "supportsExceedsLimitStatistics": false, "supportsAdvancedQueries": false, "supportedQueryFormats": "JSON, geoJSON, PBF", "isDataVersioned": false, "ownershipBasedAccessControlForFeatures": {"allowOthersToQuery": true}, "useStandardizedQueries": true, "advancedQueryCapabilities": { "useStandardizedQueries": true, "supportsStatistics": false, "supportsPercentileStatistics": false, "supportsHavingClause": false, "supportsOrderBy": false, "supportsDistinct": false, "supportsCountDistinct": false, "supportsPagination": false, "supportsLod": false, "supportsQueryWithLodSR": false, "supportsTrueCurve": true, "supportsQueryWithDatumTransformation": true, "supportsReturningQueryExtent": true, "supportsQueryWithDistance": true, "supportsSqlExpression": false, "supportsTimeRelation": true, "supportsSqlFormat": false, "supportsQueryAnalytic": false }, "supportsDatumTransformation": true, "dateFieldsTimeReference": null, "preferredTimeReference": null, "datesInUnknownTimezone": false, "hasMetadata": true, "isDataArchived": false, "archivingInfo": { "supportsQueryWithHistoricMoment": false, "startArchivingMoment": -1 }, "supportsCoordinatesQuantization": true, "supportsDynamicLegends": false }
