position e-paper: Burning wood is not climate-neutral this clarifies a team of scientists around Prof. Dr. Pierre Ibisch from the University for Sustainable Development in Eberswalde (HNEE, Germany) on the basis of worldwide research work. Even the use of wood in durable products can be detrimental to the climate – especially when the harvesting of wood impairs the functionality of forests.
Study: The researchers found that the rate of decay of the deadwood is influenced by the tree species, temperature and precipitation. The shortest deadwood residence times were for wood derived from beech (F. sylvatica). In the warmest locations 90% of the biomass had decomposed after 27 years, in the average locations after 35 years and in the coldest locations after 54 years.
Study: Species-rich subtropical forests can absorb on average twice as much carbon as monocultures. With a mixture of native tree species, it is therefore possible to achieve higher productivity and thus better protect the climate.
