Item Information

snippet:	The Tree Mortality indicator shows where mortality has occurred, often attributed to outbreaks of insects and pathogens. For the TCA, the percent of each LTA with detected mortality is calculated. This dataset contains binary rasters showing presence of tree mortality in the past 5 years for all TCA Assessment years from 2020-present.

Polygons are created by aerial sketch mapping, and coded for defoliation and mortality, in addition to other damage codes. Defoliation and mortality layers were created from the polygon data and the attribute codes. The layers were merged to compensate for difficulties in identifying defoliation separately from mortality in hardwoods vs. conifer forests. Areas that were defoliated during three of the five years in each time period have significant impacts and likely are experiencing mortality, so these polygons were added to the mortality layer. The layer includes areas with mortality classed as “very light”. There is a one-year lag between the source data and the TCA Assessment year. For instance, the 2024 TCA Assessment used data from 2019-2023 aerial detection surveys to calculate the 0-5 year mortality metric, with all other assessment years following this same pattern.</span></span></p><p><span style='font-weight:bold;'><span>Data Format:</span></span><span><span> Raster data are binary: (1) presence or (0) absence. </span></span></p><p><span style='font-weight:bold;'><span>Spatial Resolution:</span></span><span><span> 240m. </span></span></p><p><span style='font-weight:bold;'><span>Source data:</span></span><span><span> </span></span><a href='https://www.fs.usda.gov/foresthealth/publications/fhaast/index.shtml' style='text-decoration:underline;'><span style='text-decoration:underline;'><span>USFS FHAAST custom product</span></span></a></p><p style='font-weight:bold;'><span><span>Additional Resources:</span></span></p><p><span><span>Details on </span></span><a href='https://usfs.box.com/s/79vx1b42xg8u6ivjombxjes36nzfhgml' style='text-decoration:underline;'><span style='text-decoration:underline;'><span>Method Changes and Source Data Versions</span></span></a></p><p><span><span>Overview of the Terrestrial Condition Assessment: </span></span><a href='https://terrestrial-condition-assessment-usfs.hub.arcgis.com/' style='text-decoration:underline;'><span style='text-decoration:underline;'><span>TCA Hubsite</span></span></a><span><span> or </span></span><a href='https://www.youtube.com/watch?v=Kf0P3cAq1rs&list=PLwRbAc4x5n94rLca1CXXuugtRDt_G666M&index=19' style='text-decoration:underline;'><span style='text-decoration:underline;'><span>Landfire Office Hour Presentation</span></span></a></p><p><span><span>Explore the results of the most recent assessment: </span></span><a href='https://apps.fs.usda.gov/gtac-toolsms/tca/' style='text-decoration:underline;'><span style='text-decoration:underline;'><span>TCA Interactive Data Viewer</span></span></a></p><p><span><span>Learn more about the TCA KPI: Dashboard link when available</span></span></p></div></div></div>
