BLM REA CYR 2013 Long-term Future (2060) Landscape Condition in Floodplain Forest and Shrub

Some of the CYR rasters intentionally do not align or have the same extent. These rasters were not snapped to a common raster per the authors' discretion. Please review selected rasters prior to use. These varying alignments are a result of the use of differing source data sets and all products derived from them. We recommend that users snap or align rasters as best suits their own projects. - The overall status of the floodplain forest and shrub CE was assessed by intersecting the Landscape Condition Model (LCM) with the CE distribution model for the current condition, near-term, and long-term future. The LCM is a way to measure the impact of the human footprint on a landscape. In the current condition, the impact on The highway system, alternative transport corridors (e.g., the Yukon and Tanana rivers), and small but impact-intense regions of placer mining, all account for the impacts to the current and near-term future landscape condition. In the long-term future, the area in the “very high” condition class is projected to decrease to 92% (Figure G-31). This 2% decrease reflects the addition and expansion of placer mining operations, the continued use of river roads, and the construction of the Ambler mining district access road, which will involve numerous river crossings. Gravel extraction and infrastructure development both degrade floodplain habitat and can facilitate the introduction of invasive species.
