Mountain Hemlock Connectivity Under Future Climate Change in the PNW

This map shows the availability of future Mountain Hemlock expansion under predicted connectivity and climate change in PNW subalpine and high footprint areas.
This map shows the current connectivity of conifers at high elevation and high human footprint of the Pacific Northwest as of 2000. It is layered over a future model of subalpine connectivity of areas of high elevation and high human footprint in the 2080. These two parameters are compared to baseline and future climate niches for Mountain Hemlock (Tsuga mertensiana) along similar regions. Mountain Hemlock is layered under the niche layer to show general Pacific Northwest the subalpine fir range of future growth under predicted climate change.
