Forest health on one coast can affect forests on the other coast

Forest health on one coast can affect forests on the other coast

Science
May 16 (UPI) -- Shrinking forests don't just have local or regional consequences. New research suggests the loss of forests on one coast can affect forest health on the opposite coast. In a new study, published this week in the journal Environmental Research Letters, scientists at the University of Washington detailed the linked fates of forests on the East and West coasts of the United States. Die-offs on one coast, whether caused by wildfire, drought or disease -- or some combination thereof -- can have a measurable impact on the health of sections of forest a few thousand miles away. "These smaller areas of forest can have continental-scale impacts, and we really need to be considering this when we're thinking about ecological changes," Abigail Swann, an assistant professor of atmosph...
'Feel good' factor not CO2 boosts global forest expansion

'Feel good' factor not CO2 boosts global forest expansion

Science
Forests are increasing around the world because of rising incomes and an improved sense of national wellbeing say researchers.The authors refute the idea that increasing levels of CO2 in the atmosphere are the key cause of the spread of trees. As countries become better off, farmers focus on good quality soils and abandon marginal lands, the authors say.As a result, trees are able to rapidly reforest these deserted areas.The study highlights the fact that between 1990 and 2015 forest growing stock increased annually by 1.31% in high income countries and by 0.5% in middle income nations, while falling by 0.72% in 22 low income countries. Several global climate models have attributed this change to what's termed CO2 fertilisation -...
Northern Forest: Plan to plant 'ribbon of woodland' across England

Northern Forest: Plan to plant 'ribbon of woodland' across England

Science
Plans to create a new Northern Forest stretching from Liverpool to Hull have been kick-started by the government.It is providing £5.7m to increase tree cover along a belt spanning Manchester, Leeds and Bradford.The project will cost £500m over 25 years. The balance of the funds will need to be raised by charity.Environmentalists have welcomed the planned 50 million new trees, but say ministers must stop allowing ancient woodland to be felled.The UK has one of the lowest rates of woodland in Europe and the area to be covered by the Northern Forest is one of the most denuded in England, with tree cover less than 8%. The emphasis of the project will be to increase tree cover around major conurbations to 20%. There will also be a focus on river valleys, where there are benefits for flood prev
German court: Ancient forest can be cleared for coal mine

German court: Ancient forest can be cleared for coal mine

World
A court in western Germany says an ancient forest near the Belgian border can be chopped down to make way for a coal strip mine. Cologne's administrative court ruled Friday against a legal complaint brought by the environmental group BUND that wanted to halt the clearance of much of the Hambach forest. The group said it would appeal the decision and seek an injunction to prevent energy company RWE from clearing the trees in the meantime. Hambach forest has become a focus of environmental protests against the expansion of a vast mine that supplies much of the coal used in nearby power plants. The coal, a light brown variety called lignite, is considered one of the most polluting forms of fossil fuel.Let's block ads! (Why?) ABC News: International
