This feature delineates forest and vegetation stands in the Yukon at a scale of 1:5,000. It is an operational level forest inventory (as opposed to a management level). This inventory has been completed in various stages, between 2013 and 2014, and delineation via softcopy from stereo images acquired in the years 2007 and 2012. Theaerialimages used for the Haines Junction region (Champagne and Aishihik Traditional Territory) had a ground sample distance (GSD) of 40 cm and were collected in both color and infrared. Theaerialimagery in the southcentral Yukonwere 1:40,000 black and white hardcopyimages, scanned at 60 microns or approximately 1m GSD.
The framework of the Cordilleran orogen of northwestern North America is commonly depicted as a ‘collage’ of terranes – crustal blocks containing records of a variety of geodynamic environments including continental fragments, pieces of island arc crust and oceanic crust. The series of maps available here are derived from a GIS compilation of terranes based on the map published by Colpron et al. (2007) and Nelson and Colpron (2007), and include modifications from recent regional mapping, The dataset includes individual terrane data for British Columbia, Yukon and Alaska, as well as a layer showing selected major Late Cretaceous and Tertiary strike-slip faults. Graphic files derived from the GIS compilation were prepared for the Northern Cordillera (Alaska, Yukon and BC), the Canadian Cordillera (BC and Yukon), Yukon, and British Columbia. These maps are intended for page-size display (~1:5,000,000 and smaller). Polygons are accurate to ~1 km for Yukon and BC, and ~5 km for Alaska. More detailed geological data are available from both BC Geological Survey and Yukon Geological Survey websites. Descriptions of the terranes, their tectonic evolution and metallogeny can be found in Colpron et al. (2007), Nelson and Colpron (2007), Colpron and Nelson (2009).The terrane map project is a collaborative effort of the BC Geological Survey and the Yukon Geological Survey.Terrane Field AttributesField NameField DescriptionField FormatTERRANETerrane AbbreviationSTRING(50)T_GROUPGrouping to which terrane belongsSTRING(50)AFFINITYPaleogeographic affinity of terraneSTRING(25)T_NAMEFull name of terraneSTRING(50)REALMPaleogeographic realm from which terrane originatedSTRING(20)AUTHORAGENOrganization author belong to at time of creationSTRING(254)AUTHORSPolygon creatorSTRING(254)DATEYear polygon was createdSTRING(254)ADMIN_DIVAdministrative Division (used to query for Yukon, BC, or Alaska).STRING(50)
This feature displays annotation codes for easy display of vegetation inventory polygons. Used in conjunction with the data set for Vegetation Inventory Poly 40K, this dataset shows labels describing the contents of each forest inventory polygon. The annotation is at a fixed scale, and is designed to be optimally displayed at a 1:50:000 scale.
A 1:20,000 version of annotation labels for the Whitehorse Vegetation Inventory. The field work for the inventory was carried out during the winter of 2004/2005 with the project delivered by the contractor in October 2005. Delineation was based on 1:10,000 black and white photography acquired by the City of Whitehorse in 2001. Mapping and DTM were available for this project based on the 2001 photography.
Cartographic representation of the Geographic Latitude / Longitude graticule at 1 degree intervals, including the Arctic Circle. This dataset was imported from the National Atlas of Canada from Natural Resources Canada at 1:2,000,000.

The Adaptive Management Framework for Yukon placer mining is complemented by traditional knowledge and monitoring of water quality objectives, aquatic health, and economic health.The aquatic Health monitoring program is governed by the Aquatic Health Monitoring Protocol.The Protocol describes the locations, timing, frequency and methods employed duringsampling, as well as the methods used to analyze sampling data. The Reference ConditionApproach (RCA) is the method chosen for assessing the health of freshwater ecosystems inthe Yukon. One RCA model was developed for bioassessment based upon benthicmacroinvertebrates, and a second model was developed to assess the diversity of fishspecies.The RCA model for invertebrates relies upon 224 reference sites collected over the period 2004 to 2010 by the University of Western Ontario, Fisheries and Oceans Canada, and theYukon government, using the same standard protocol. The invertebrate data set was analyzedat the family level.There are two fundamental steps in the process of developing the predictive model. The first isto classify the reference sites based on their biological characteristics. This requires defining anumber of community types based on the taxonomic composition. The second step is todetermine a subset of habitat attributes that are associated with those community types.Following this step the number and type of organisms expected to occur at any given site canbe determined from habitat attributes.For more information, contact the Yukon Placer Secretariat
