{ "currentVersion": 11.3, "cimVersion": "3.3.0", "id": 63, "name": "Challenges in Managing Mature and Old Growth Forests", "type": "Feature Layer", "description": "This data set is derived from three sources, version 4 of the 1990-2020 wildland-urban interface of the conterminous United States, the current version of the fireshed registry information, and the 2023 mature and old growth forest inventory analysis. The Wildland-Urban Interface (WUI) is the area where houses meet or intermingle with undeveloped wildland vegetation. This makes the WUI a focal area for human-environment conflicts such as wildland fires, habitat fragmentation, invasive species, and biodiversity decline. Using geographic information systems (GIS), we integrated U.S. Census and USGS National Land Cover Data, to map the Federal Register definition of WUI (Federal Register 66:751, 2001). These data are useful within a GIS for mapping and analysis at national, state, and local levels.This layer contains information about the number of housing units in fireshed Census blocks, proportionate to the area of the blocks that fell within the fireshed. The values for 1990 and 2020 were used to determine the change over time, which was then classified into five classes using the following breakpoints:Loss or No Growth = Very Low (1): <0% Increase in Housing UnitsMinimal Growth = Low (2): 0-10% Increase in Housing UnitsModerate (3): 10-50% Increase in Housing UnitsHigh (4): 50-100% Increase in Housing UnitsVery High (5): >100% Increase in Housing UnitsThis data was then combined with the MOGCA Fire Deficit score to produce a bivariate visualization.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. Fireshed areas in the Fireshed Registry are approximately 250,000 acre accounting units that are delineated based on a smoothed building exposure map of the continental United States.",
