{ "currentVersion": 10.91, "cimVersion": "2.9.0", "id": 29, "name": "Potential Grassland Habitat", "type": "Feature Layer", "description": "This dataset is a component of a complete package of products from the Connect the Connecticut project. Connect the Connecticut is a collaborative effort to identify shared priorities for conserving the Connecticut River Watershed for future generations, considering the value of fish and wildlife species and the natural ecosystems they inhabit. Click here to download the full data package, including all documentation.This dataset represents a set of terrestrial core areas for grassland birds based on the eastern meadowlark as a representative species for grassland birds. In combination with the terrestrial tier 1 and 2 core areas they spatially represent the ecological core area network derived from the CTR LCD project. The CTR LCD planning team decided that eastern meadowlark and the grasslands they represent warranted separate treatment from the other terrestrial representative species due to their unique association with a culturally created and maintained habitat. Consequently, eastern meadowlark and the grasslands they represent were not explicitly included in the derivation of the tier 1 and 2 core areas. However, some grasslands did get included in the tier 1 and 2 cores areas due to other considerations, such as meeting the needs of other representative species (e.g., wood turtle) that also use grasslands to some extent, and growing out cores from their seeds through lower-valued areas that included grasslands. Grassland bird cores were derived from the eastern meadowlark landscape capability layer, which is a measure of habitat capability and climate suitability for the species. Briefly, for each disjunct patch of habitat (defined as contiguous cells having landscape capability index >0.03), we computed the maximum landscape capability index value. Next, we rank-ordered the habitat patches from highest value to lowest maximum value and selected the top number of patches in which the cumulative landscape capability value (i.e. ,the sum of the landscape capability index in the patches) equalled 50% of the species' total landscape capability value for the CTR watershed. Thus, the final set of 1448 eastern meadowlark cores captured 50% of the landscape capability for this species and represented 1.15% of the CTR landscape. Considerations for Using Data LayerThe terrestrial tiered cores and connectors in combination with the grassland bird cores canserve as a starting point for a regional conservation network that can be used incombination with other sources of information to direct action.Although the grassland bird core areas are presented as discrete entities, it is important torecognize that their boundaries are, in fact, \"fuzzy\" and are best interpreted as generalplaces to focus attention.Lastly, as noted previously for the tier 1 cores and connectors, all three tiers can and doinclude some low-intensity development, minor roads and agriculture.", "geometryType": "esriGeometryPolygon", "sourceSpatialReference": { "wkid": 32145, "latestWkid": 32145, "xyTolerance": 0.001, "zTolerance": 0.001, "mTolerance": 0.001, "falseX": -5123000, "falseY": -14708800, "xyUnits": 10000, "falseZ": -100000, "zUnits": 10000, "falseM": -100000, "mUnits": 10000 }, "copyrightText": "University of Massachusetts", "parentLayer": null, "subLayers": [], "minScale": 0, "maxScale": 0, "referenceScale": 0.0, "drawingInfo": { "renderer": { "type": "simple", "symbol": { "type": "esriSFS", "style": "esriSFSSolid", "color": [ 255, 255, 0, 255 ], "outline": null } }, "scaleSymbols": true, "transparency": 30, "labelingInfo": null }, "defaultVisibility": true, "extent": { "xmin": 447032.4667999996, "ymin": 197611.3228999991, "xmax": 457419.0237999996, "ymax": 207401.8147, "spatialReference": { "wkid": 32145, "latestWkid": 32145, "xyTolerance": 0.001, "zTolerance": 0.001, "mTolerance": 0.001, "falseX": -5123000, "falseY": -14708800, "xyUnits": 10000, "falseZ": -100000, "zUnits": 10000, "falseM": -100000, "mUnits": 10000 } }, "hasAttachments": false, "htmlPopupType": "esriServerHTMLPopupTypeAsHTMLText", "displayField": "Notes", "typeIdField": null, "subtypeFieldName": null, "subtypeField": null, "defaultSubtypeCode": null, "fields": [ { "name": "OBJECTID", "type": "esriFieldTypeOID", "alias": "FID", "domain": null }, { "name": "Shape", "type": "esriFieldTypeGeometry", "alias": "Shape", "domain": null }, { "name": "Shape_Length", "type": "esriFieldTypeDouble", "alias": "Shape_Length", "domain": null }, { "name": "Shape_Area", "type": "esriFieldTypeDouble", "alias": "Shape_Area", "domain": null }, { "name": "Notes", "type": "esriFieldTypeString", "alias": "Notes", "length": 150, "domain": null }, { "name": "Acres", "type": "esriFieldTypeSmallInteger", "alias": "Acres", "domain": null }, { "name": "FieldType", "type": "esriFieldTypeString", "alias": "FieldType", "length": 30, "domain": null }, { "name": "FieldTypeVHRLC", "type": "esriFieldTypeString", "alias": "FieldTypeVHRLC", "length": 30, "domain": null } ], "geometryField": { "name": "Shape", "type": "esriFieldTypeGeometry", "alias": "Shape" }, "indexes": [ { "name": "FDO_OBJECTID", "fields": "OBJECTID", "isAscending": true, "isUnique": true, "description": "" }, { "name": "FDO_Shape", "fields": "Shape", "isAscending": true, "isUnique": false, "description": "" } ], "subtypes": [], "relationships": [], "canModifyLayer": true, "canScaleSymbols": false, "hasLabels": false, "capabilities": "Query,Map,Data", "maxRecordCount": 2000, "supportsStatistics": true, "supportsExceedsLimitStatistics": true, "supportsAdvancedQueries": true, "supportedQueryFormats": "JSON, geoJSON, PBF", "isDataVersioned": false, "ownershipBasedAccessControlForFeatures": {"allowOthersToQuery": true}, "useStandardizedQueries": true, "supportedSpatialRelationships": [ "esriSpatialRelIntersects", "esriSpatialRelContains", "esriSpatialRelCrosses", "esriSpatialRelEnvelopeIntersects", "esriSpatialRelIndexIntersects", "esriSpatialRelOverlaps", "esriSpatialRelTouches", "esriSpatialRelWithin", "esriSpatialRelRelation" ], "advancedQueryCapabilities": { "useStandardizedQueries": true, "supportsStatistics": true, "supportsPercentileStatistics": true, "supportsHavingClause": true, "supportsOrderBy": true, "supportsDistinct": true, "supportsCountDistinct": true, "supportsPagination": true, "supportsLod": false, "supportsQueryWithLodSR": false, "supportsTrueCurve": true, "supportsQueryWithDatumTransformation": true, "supportsReturningQueryExtent": true, "supportsQueryWithDistance": true, "supportsSqlExpression": true, "supportsTimeRelation": true, "supportsSqlFormat": false, "supportsQueryAnalytic": false }, "supportsDatumTransformation": true, "dateFieldsTimeReference": null, "preferredTimeReference": null, "datesInUnknownTimezone": false, "hasGeometryProperties": true, "geometryProperties": { "shapeAreaFieldName": "Shape_Area", "shapeLengthFieldName": "Shape_Length", "units": "esriMeters" }, "hasMetadata": true, "isDataArchived": false, "archivingInfo": { "supportsQueryWithHistoricMoment": false, "startArchivingMoment": -1 }, "supportsCoordinatesQuantization": true, "supportsDynamicLegends": true, "serviceItemId": "23a4addee2f5445a8191479ec327b124" }
