BLM REA CYR 2013 Near-Term Future (2025) Anthropogenic Cumulative Impacts

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 Cumulative Impacts analysis included the primary, measurable Change Agent variables that are likely to have the largest and most direct impact in the Central Yukon study area in the future. However, in order to “sum” the impacts, thresholds for meaningful change had to be defined for each variable. Cumulative Impacts are not specific to any ecosystem constituent or process but are intended to be representative of the ecosystem as a whole, so thresholds for meaningful change are based on model variability and the potential to impact management decisions. This dataset does not assess the likely collinearity of the change agents, but rather considers each change agent as a separate stressor that will differentially impact CEs and other resources in the study area. The inverse of this dataset could be seen as a landscape vulnerability index (LVI) that could be used to assist in future resource planning efforts.
