A new research project at the Andrews Forest aims to shed light on how changes in temperature and precipitation affect patterns of biodiversity. The Forests of Oregon Elevation Gradient (FOREG) is a network of large sample plots, established in 2019, within the HJ Andrews Experimental Forest. Field studies and experiments will test the importance of species interactions to changes in density dependence and biodiversity across environmental gradients.The FOREG project was designed to dovetail and connect with the long-running Reference Stand study at the Andrews Forest. FOREG is also a part of the much broader Smithsonian "Big Plot" program. The FOREG study is run by Joseph LaManna at Marquette University. A new photo gallery highlights FOREG summer field work.
