Buffer zones surrounding mapped watercourses and wetlands where forest activity is regulated on Crown land to maintain water quality and aquatic habitat.

One of the spatial views of the BC WATERSHED ATLAS 50K, which is the digital basemap representation of the aquatic Man-made waterbodies, Wetlands and Double-line Rivers based on the 1:50,000 scale Canadian National Topographic Series of Maps.

CryoGeographic Consulting, in association with Palmer Environmental Consulting Group Inc., provided Yukon Energy, Mines and Resources and Yukon Environment with the results of the mapping and classification of wetlands and adjacent upland habitat in the Indian River valley and its major tributaries. This report and its accompanying map set have been updated to reflect study area expansion and additional field reconnaissance completed in the summer of 2017. Interpretation of shallow water wetlands within disturbed landscapes was completed by Ducks Unlimited Canada and incorporated. Five classes of wetlands are distinguished - bogs, fens, swamps, marshes and shallow water - based on field investigations and interpretation of high-resolution aerial photography and satellite imagery.

1:250,000 NTDB Wetlands

1:50,000 NTDB Wetlands Based on Edition 2.x.

To support the WAWA program at the Department of Environment and Local Government and alert primary users to the location of wetlands and possible regulatory requirements for land development. The wetlands map is intended for planning purposes only. The wetland boundaries are only approximate.

Knowledge of the location of Earth’s surface water in time and space is critical to inform policy decisions on environment, wildlife, and human security. Dynamic surface water maps generally represent water occurrence, also referred to as inundation frequency, depicting the percentage of valid observations when water is detected at the surface. The location and duration of surface water varies from areas of permanent water with 100% inundation frequency where water is always observed, to areas of permanent land with 0% inundation where water never occurs. Between these two extremes are areas of ephemeral water that experience periodic flooding with inundation frequencies between 0-100%. National-scale dynamic surface water information was generated for years 1984-2023 at 30m spatial resolution from the historical Landsat archive over Canada. The complete dataset consists of annual water maps and derived products including inundation frequency and inter-annual wetting and drying trends calculated using per-pixel logistic regression. The complete dataset enables an assessment of the timing, duration, and trends towards wetting or drying at regional to national scales.
