Ecoregions 2014 - 1M


Data Identification
Abstract: Ecoregions of Yukon, 2014 is an update to the Yukon portion of the 1995 National Ecological Framework (NEF) described in Ecoregions of Yukon (Smith et al 2004). Because of people’s familiarity with the 1995 NEF, and its use in management and planning, these ecoregion revisions attempted to retain the 1995 divisions unless there were compelling reasons to change them. In Yukon there were several compelling reasons to revise the 1995 NEF: 1) capitalize on availability of digital inventory and knowledge and improve or adjust the 1995 mapping as necessary, 2) harmonize stratification along jurisdictional borders, 3) incorporate line work updates to the Soil Landscape polygons by Agriculture and AgriFood Canada (AAFC) happening concurrently, and 4) include Yukon revisions in a national update of NEF ecozones across Canada - led by Environment Canada (CCEA 2017). Mapping the ecoregions of Yukon is largely a top-down process and the divisional hierarchy is nested. The lowest level of the hierarchy is the Soil Landscapes of Canada unit (Soil Landscape Component, or SLC). SLCs are organized according to a uniform set of national soil and landscape criteria that are based on permanent natural attributes. SLCs polygons are not published in this release. Ecozones, ecoregions and ecodistricts are subdivisions at the continental scale of climatic zones; attention to physiography increases as map scale increases. There are many reasonable ways to distinguish Yukon ecoregions. Ecoregions are delineated principally on abiotic features, such as bedrock geology, glacial history and physiography, and so are relatively stable (i.e. enduring) over time. While considering changes to the 1995 NEF, the project team continued to recognize major physiographic and climatic distinctions. At the ecozone level the team included a stronger regional climate element and related the ecozone level to the bioclimate framework. The Ecoregions of Yukon concept is used for broad scale management applications. Its structure helps define ecologically relevant management units at various scales. The Ecoregions of the Yukon Territory (Smith et al. 2004) describes Yukon’s ecozones and ecoregions represented in the 1995 NEF (ESWG 1995). This reference continues to be a useful and relevant resource the Ecoregions of Yukon, 2014. For a fulsome treatment of the updates in the Ecoregions of Yukon, 2014 please refer to the report “Ecoregions of Yukon: Revisions to the Yukon portion of the National Ecological Framework.” (McKenna, K, J. Meikle and N. Flynn 2014).
Purpose: In 2011, the Yukon Ecological and Landscape Classification Program formed an ecoregion working group. The goal was to revise the 1995 mapping to match newly developed ecological regions in the Northwest Territories, and to accommodate minor revisions made in British Columbia and significant revisions in Alaska. The Yukon ecoregion revisions also incorporated newly available input information such as surficial and land cover/vegetation mapping, Digital Elevation Models and data from advances in GIS technology. For more information about the Ecoregions of Yukon, 2014 revision and comparison to the National Ecological Framework published in 1995 please refer to the Yukon Ecological and Landscape Classification and Mapping Guidelines, Case Study 1: Ecoregions of Yukon (Environment Yukon 2016).

Constraints: Ecoregions of Yukon, 2014 may be used at scales larger than 1:250,000 with caution. This mapping is deliberately extended across the ocean, lakes, glaciers, etc to facilitate intersection with a terrestrial landcover layer of the user’s choice. Although every effort has been made to ensure the correctness of the report and spatial products, there still may be errors. Please report errors in the data to the Custodian.

Quality
Scope: Dataset
Lineage: The 2014 Ecoregion dataset was developed by the Yukon Ecoregion Technical Working Group (YETWG) which was comprised of multidisciplinary scientists who refined the existing 1995 stratification through fieldwork and ecosystem mapping in support of land use planning. The foundation of this refinement stemmed from an upgrade of the Soil Landscapes of Canada (SLC), which is the foundational linework to the National Ecological Framework, from a 1:1,000,000 map base to a 1:250,000 map base along with a revision of mapping criteria that makes the SLC more useful to land and resource management.
