Methodology:

Methodology_Type: Field

Methodology_Description:

Measuring forest characteristics uses a number of methods. The majority of the field measurement methods were taken directly from the FIA Northeast Field Guide version 1.6 (USFS FIA 2002). Additional methods and sampling protocol details are also included in the data publication download.
