BLM REA YKL 2011 Long-Term Future (2060) Landscape Condition Status in Current (2012) Modeled High Prey Density Distribution of Gray Wolf in the Yukon River Lowlands - Kuskokwim Mountains - Lime Hills

Metadata Updated: October 10, 2019

Some of the YKL 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 landscape condition model evaluates the degree of human impact on the landscape. Wolves tend to avoid areas of human development and hunting pressure can cause reductions in wolf populations near villages. In winter, snowmachine activity and trails can displace animals and disrupt their activities; however, trails can also provide a well packed travel corridor. Hunting and trapping pressures along trails can be high, especially later in the winter when animals are more stressed, and the benefit to wolves using the trail system is likely outweighed by the potential costs associated with human access. In the Kenai National Wildlife Refuge, winter movements indicated that wolves avoided year-round public use roads that had substantial traffic, but utilized seasonally closed roads and roads with little human use. In some areas of the state, predation by wolves keep ungulate populations significantly below the habitat’s carrying capacity, thus limiting ungulate hunting and trapping opportunities for humans. As a result, intensive management programs (i.e., predator control) have been enacted in some areas to reduce wolf population numbers and increase ungulate harvest opportunities. The long-term future (2060) landscape condition was extracted to the current (2012) modeled high prey density distribution of gray wolf. The intersection of the gray wolf high prey density distribution with the Landscape Condition Model indicates that the majority of wolf habitat in the YKL study area is classified as being in very high (intact) condition. Long-term projections (2060) of landscape condition suggest a slight decrease in very high quality condition and a slight increase in low condition, particularly around the villages of Galena and McGrath, as well as along both the Yukon and Kuskokwim river corridors, which are also areas of high prey density habitat.
