FIA is the nation's forest census. It provides the information needed to assess America’s forests. FIA reports on status and trends in forest area and location; in the species, size and health of trees; in total tree growth, mortality and removals by harvest; in wood production and utilization rates by various products; and in forest land ownership.
The enhanced FIA program includes information relating to tree crown condition, lichen community composition, soils, ozone indicator plants, complete vegetative diversity and coarse woody debris.
The FIA program
is managed nationally by the research and development organization within the USDA Forest Service in cooperation with state and private forestry and national forest systems. FIA has been in operation under various names (Forest Survey, Forest Inventory and Analysis) for some 70 years.
The program is implemented in Texas in cooperation with Texas A&M Forest Service, which conducts data collection, and private landowners who grant access to their lands for data collection purposes.
