<DIV STYLE="text-align:Left;font-size:12pt"><DIV><DIV><P><SPAN>This dataset combines summaries of Climatic Water Deficit and summaries of Mature and Old Growth forest area estimates from the Forest Inventory Analysis for the Mature and Old Growth Forest inventory to Firesheds. </SPAN></P><P><SPAN>The Fireshed Registry is a geospatial dashboard and decision tool built to organize information about wildfire transmission to communities and monitor progress towards risk reduction for communities from management investments. The concept behind the Fireshed Registry is to identify and map the source of risk rather than what is at risk across all lands in the continental US. While the Fireshed Registry was organized around mapping the source of fire risk to communities, the framework does not preclude the assessment of other resource management priorities and trends such as water, fish and aquatic or wildlife habitat, or recreation. The Fireshed Registry is also a multi-scale decision tool for quantifying, prioritizing, and geospatially displaying wildfire transmission to buildings in adjacent or nearby communities.</SPAN></P><P><SPAN>The Climatic Water Deficit was masked to federal ownership (Forest Service and BLM). The mean value of each climate layer for each time period and climatic pathway for every fireshed was calculated. The climatic pathways used were RCP 4.5 and RCP 8.5. The time periods were historic based on observations (1970 -1999) and current (2000 - 2029), mid-century (2035 - 2064), and end-century (2070-2099) based on modelled results. Quintile breakpoints and histograms were calculated for all variables, including absolute change and percent change, across the entire time period and multiple climatic pathways. The squared SE acres for Mature and Old Growth were calculated for all layers, time periods, and pathways. Subject Matter Experts decided on appropriate breakpoints for the 5 classes (Very Low, Low, Moderate, High, Very High) after consulting the quintile breakpoints and histograms. All layers were classified according to those breakpoints. The total acres for Mature and Old Growth forests were calculated by class, time step, and climatic pathway for all layers. </SPAN></P><P STYLE="font-weight:bold;margin:0 0 0 0;"><SPAN><SPAN>Map layer name: Climatic Water Deficit Projections</SPAN></SPAN></P><P STYLE="margin:0 0 0 12;"><SPAN STYLE="font-weight:bold;"><SPAN>Creator</SPAN></SPAN><SPAN>: John B.
