Predictive ecosystem mapping underestimates wetland area by approximately two thirds compared to detailed mapping in the Indian River drainage. The Tr’ondëk Hwëch’in Traditional Territory contains large wetland concentrations in the Ogilvie Mountains and Tintina Trench. Overall wetland coverage for all study areas is estimated to be upwards of 10% of the landscape, influenced by terrain, sedimentation, periglacial processes, and discontinuous permafrost.
Use Cases
- Identify areas of wetland abundance for conservation planning based on regional PEM data.
- Compare wetland density across ecoregions like the Klondike Plateau based on topographic characteristics.
- Locate large wetlands distal to the Yukon River for hydrological studies based on Pleistocene base level change.
- Frame land management decisions weighing economic and environmental factors based on regional wetland distribution.
Strengths
- Includes a quality control comparison quantifying PEM underestimation of wetland area by approximately two thirds.
- Provides specific geographic findings, such as wetland density on the Klondike Plateau being approximately 50% less.
- Estimates overall wetland coverage for all study areas to be upwards of 10% of the landscape.
Limitations
- Column-level documentation is absent; field semantics must be inferred after download.
- Row count is unknown, which may limit suitability assessment.
- Data may reflect geographic bias inherent to the specific study regions in Yukon and Alaska.
