Abstract

Simulations of cool-temperate forest growth in response to climatic change using the JABOWA computer model show that a decrease of 600 growing degree-days causes red spruce (Picea rubens) to replace sugar mapple (Acer saccharum) as a dominant tree. These changes are delayed 100-200 yr after the climatic cooling. Delayed responses imply that fossil pollen deposits, even if they faithfully record the abundance of trees in forests, may not be able to resolve climatic changes within 100-200 yr, or to record very brief climatic events.
