Old Growth Forests May Shed Light On Worldwide Greenhouse Effect

HOUGHTON, MI--Michigan Technological University researchers are studying ecosystem responses to global climate change in old growth forests in an attempt to find a part of the solution to the greenhouse effect problem.

Plants are important absorbers of atmospheric carbon dioxide, which, in high concentrations affects global climate change. Old-growth forests represent one plant community type which has not been well researched for carbon, water, and energy exchange.

Dr. Jiquan Chen, associate professor in the School of Forestry and Wood Products at Michigan Tech, heads a team of MTU researchers whose aim is to determine the role of Pacific Northwest landscapes in the global carbon budget. They measure the fluxes of carbon dioxide, water and energy budgets at several managed forests in the Pacific Northwest to offer baseline information on the roles of managed ecosystems in a broader context of landscapes and in the cumulative effects of climate change at landscape scales.

The data from a continued flow of carbon dioxide, water, and energy budgets can help researchers understand and predict the role of terrestrial ecosystems in global carbon and water budgets. In early 1998, Chen and his team began measuring the flows of carbon dioxide and water on 550-year-old and 40-year-old Douglas fir forests at a research site near the Wind River in southern Washington. Their initial data suggested that both the old growth and the 40-year-old forest absorbed more carbon than they released. However, the young forest had a much higher carbon assimilation budget than the old-growth forest under similar climatic conditions. In addition, the net carbon dioxide absorption and releases in the young plantation can be several times higher than in the old-growth forest under some extreme conditions.

Chen and his team have extended their current measurements to the non-growth season (September 98-May 99) to compare the data between g
