Ancient pollen samples and a new statistical approach may shed light on the global rate of change of vegetation and eventually on how much climate change and humans have played a part in altering landscapes, according to an international team of researchers. We know that climate and people interact with natural ecosystems and change them, said Sarah Ivory, assistant professor of geosciences and associate in the Earth and Environmental Systems Institute, Penn State. Typically, we go to some particular location and study this by teasing apart these influences. In particular, we know that the impact people have goes back much earlier than what is typically accepted as the case. However, we haven t been able to observe the patterns created by these processes globally or long-term.

UNIVERSITY PARK, Pa. With a sled full of wooden stakes, green tree shelters and saplings in tow, Tim White made his way across acres of mud and grass and at times ankle-deep water to a three-person team planting saplings along a trench. The group was one of several from Penn State that spent a Saturday in April planting nearly 500 shrubs and trees across White’s 15-acre property in Centre Hall, Pennsylvania.
