Climate change impacting tree specie density, research finds

Climate change could begin to impact the density of tree species and in turn the effectiveness of ecosystem conservation, finds new study. The research, led by the University of Alcalá (UAH), in Spain, and including researchers at the University of Birmingham, draws data from across Europe and North America to show that tree species in the Northern Hemisphere are starting to become denser in colder and wetter regions. Researchers analysed data from over two million trees, representing over 70 species widely distributed across Europe and the United States; investigating whether the changes in density could be attributed to species characteristics.
