The Southeast Tree Research and Education Site (SETRES)

← Return to Forest Genetics and Ecosystems Biology

Objectives
To understand and model the mechanisms that permit loblolly pine to respond to “global change.”

Design
The SETRES site is a randomized complete block 2 × 2 factoral design, replicated in 4 blocks. The main effects are nutrient and water availability and the split-plot effect is CO2 fertilization.
