It takes two to measure this Giant Sequoia

Teodora Rautu and Eva Lopez, Biological Science Technicians on the field crew for the USGS Western Ecological Research Center's Sierra Nevada Forest Dynamics project, work together to measure the diameter of a Giant Sequoia. Every tree in the project's long-term study plots are re-measured every 5 years, not only for determining the size of the trees but also for tracking tree growth rates. Most of the trees can be measured by one person, but this truly enormous Giant Sequoia took some teamwork!
