Parent Layer: Carbon Layers on National Forest System Lands

Name: Ratio of Live Aboveground Carbon to Dead (2023)

Display Field: FORESTNAME

Type: Feature Layer

Geometry Type: esriGeometryPolygon

Description: This data layer provides annualized estimates (1990-2023) for seven forest carbon pools (aboveground live, belowground live, soil organic carbon, forest floor, down dead wood, standing dead trees, understory vegetation) for each National Forest System unit based on information from the FIA program and the Carbon Calculation Tool (CCT) - https://www.nrs.fs.usda.gov/pubs/2394 . These estimates were used to make maps portraying trends in live to dead tree ratios by joining CCT estimates to the Forest Service administrative boundary layer. Spatial Extent: NFS system landsUnits: Total forest C stocks by year (Tg), C pools (%), C stock change (Tg/yr), average C stock density by year (Mg/ha), HWP C storage over time (Tg) [regional summary], % forest disturbance by year, C loss by disturbance type over time (Mg/ha), % reduction in non-soil C by disturbance, stand age distribution in 2011, NPP-stand age curves (Mg C/ha/yr), accumulated C over time (Tg).
