The FIA program’s mission‐ Since 1928

• “make and keep current a comprehensive inventory and analysis of the present and prospective conditions and requirements of the renewable resources of the forest and rangelands of the United States”

1928 McSweeney/McNary 

Act1978 Research Act

1998 Agricultural Act, or “Farm Bill”

• An integrated inventory and monitoring program capable of providing scientifically reliable indicators of sustainable forestry

The FIA program’s mission

• The FIA program collects strategic (state or multi‐county level) data on the:

• Status,

• Trends, and 

• Resource conditions, including forest health for all forest lands in a consistent fashion across the US

• Comprehensive forest inventory for each of the 50 States, Puerto Rico, and Trust Territories

• Annualized system operating in every State, every year

• Every 5‐10 years in the islands

• Over 250 State and Island reports since 1928

• 9 National Assessments since 1953

The FIA program’s scope

FIA zones of responsibilities

SRS has responsibility for PR and USVI

PNW  has responsibility for Pacific Island Territories
