Independent: More than six million larch trees are to be cut down in Wales to try to halt the spread of a deadly disease, according to a report. Phytophthora ramorum, whose first name means literally plant destroyer, was first found in the UK at a garden centre in Sussex in 2002 and was first found in Wales just five years ago. It has not yet been found on trees in Scotland, but the fungus-like pathogen has been detected in the south-west of the country. In January, leading scientists warned Britains...

Influence increased atmospheric CO2 concentration European trees

2015-05-11 19:02:00| Climate Ark Climate Change & Global Warming Newsfeed

ScienceDaily: Increased atmospheric CO2 concentrations have already caused large-scale physiological responses of European forests. In particular, the efficiency of water-use of trees, which is coupled to the uptake of CO2 during photosynthesis of leaves and needles has changed significantly. According to the study of a large, interdisciplinary team of researchers, European broadleaf and coniferous trees have increased their water-use efficiency since the beginning of the 20th century by 14% and 22%, respectively....
