Terrestrial Condition Assessment (TCA) Insect and Disease Hazard

These include forests with overly high stand densities and where soil/site conditions contribute to drought. The basis for assigning risk is the expectation that 25% or more of live basal area (three times the natural background rate of mortality) will die over the next 15 years due to insects and diseases. Because the NIDRM 2018 map is the most recent update, it has been reused each year for TCA Assessments from 2020-present.</p><p><strong>Format:</strong> Raster data are binary: (1) at risk or (0) not at risk</p><p><strong>Resolution:</strong> 240m</p><p><strong>Source: </strong><a href="https://www.fs.usda.gov/science-technology/data-tools-products/fhp-mapping-reporting/national-insect-disease-risk-and-hazard-mapping" rel="nofollow ugc noopener noreferrer" target="_blank"><u>NIDRM 2018</u></a></p><p><strong>Additional Resources:</strong></p><p>Details on <a href="https://usfs.box.com/s/79vx1b42xg8u6ivjombxjes36nzfhgml" rel="nofollow ugc noopener noreferrer" target="_blank"><u>Method Changes and Source Data Versions</u></a></p><p>Overview of the Terrestrial Condition Assessment: <a href="https://terrestrial-condition-assessment-usfs.hub.arcgis.com/" rel="nofollow ugc noopener noreferrer" target="_blank"><u>TCA Hubsite</u></a> or <a href="https://www.youtube.com/watch?v=Kf0P3cAq1rs&list=PLwRbAc4x5n94rLca1CXXuugtRDt_G666M&index=19" rel="nofollow ugc noopener noreferrer" target="_blank"><u>Landfire Office Hour Presentation</u></a></p><p>Explore the results of the most recent assessment: <a href="https://apps.fs.usda.gov/gtac-toolsms/tca/" rel="nofollow ugc noopener noreferrer" target="_blank"><u>TCA Interactive Data Viewer</u></a></p><p>Learn more about the TCA KPI: <a href="https://cxodashboard.dl.usda.gov/t/NRE/views/EcologicalConditionOutcomes_17531128629260/EcologicalOutcomes" rel="nofollow ugc noopener noreferrer" target="_blank"><u>TCA Dashboard</u></a></p><p>*if you have trouble viewing the Dashboard, please submit a <a href="https://usdagcc.sharepoint.com/sites/fs-wo-cdoc/SitePages/Dashboards.aspx" rel="nofollow ugc noopener noreferrer" target="_blank"><u>Tableau Viewer Access Request</u></a></p></div></div></div><div><br>This record was taken from the USDA Enterprise Data Inventory that feeds into the <a href="https://data.gov">https://data.gov</a> catalog.
