Regional Ecosystems Regional Ecological Setting Watersheds The planning region is generally defined by the Porcupine River watershed, a major sub-basin of the Yukon River. Ecosystems can be described at a range of scales: Major Features: The hydrologic regime is Northern, with very low winter flows and Ecoregions and Ecodistricts (1:1M - 1:250K) ● Continuous permafrost dramatic variation in summer flow. The North Yukon Planning Region occurs within the ● Unglaciated for at least 200,000 years (Beringia) Wildfire plays a large role in determining Cordillera Ecozone and includes six Ecoregions.

Terrain and vegetation conditions. Biophysical units form the basis for a range of planning and management interpretations. A detailed biophysical map has been prepared for the entire planning region (figure 2). This is the first regional biophysical map to be prepared in Yukon.
