Study: Can land ecosystems go from being a carbon sink to a carbon source in the future? The study investigates whether climate change-induced temperature changes will bring the carbon uptake and release of terrestrial ecosystems to a tipping point.
Study: A comparatively large amount of carbon from the atmosphere is also bound in the soil under old trees. Thus, old trees make an important contribution to climate protection above and below ground. This must be taken into account in timber harvesting if climate protection in the forest is to gain in value.
Study: The researchers show how that the Nitrogen input in forests has much more impact than the climate change so far. The data came from 100,000 coniferous and deciduous trees in 442 even-aged pure stands from 23 European countries.
The study of the Naturwald Akademie Germany shows how the climatic performance of the forest can be improved in Europe through near-natural, low-impact forestry. In the ideal case, forests can bind twice as much CO2 from the atmosphere each year. For this to happen, the current practice of forest management would have to change throughout Europe.
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.
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.
