Milestones

Legacy tree data enables researchers to answer important questions using state-of-the-art analyses and statistical tools.

The following publications and presentations were delivered by project personnel from the US Forest Service and six universities. As of April, 2016 project cooperators have collected new biomass measurements on over 1700 trees in United States' forests (see Table 1).
