More than eight million trees lost this winter in the UK

More than eight million trees lost this winter in the UK

Science
It is the untold story of the winter storms. More than eight million trees have been brought down and many are now threatened by another two named storms bearing down on Britain.Forest managers warn that already "catastrophic" damage will be made worse by Storms Dudley and Eunice.There are warnings that the heating climate is making our weather more severe and unpredictable, and that management and planting strategies must adapt more quickly.Forest ranger Richard Tanner says that he's never seen a real battlefield, but the west shore of Windermere now reminds him of photographs he has seen."It looks like someone's set off a bomb."All around are the giant root plates of fallen trees, some the size of caravans, studded with rocks torn from the earth."There's three tonnes of tree and then fiv...
Amazon deforestation: Record high destruction of trees in January

Amazon deforestation: Record high destruction of trees in January

Science
ReutersThe number of trees cut down in the Brazilian Amazon in January far exceeded deforestation for the same month last year, according to government satellite data.The area destroyed was five times larger than 2021, the highest January total since records began in 2015.Environmentalists accuse Brazil's President Jair Bolsonaro of allowing deforestation to accelerate.Protecting the Amazon is essential if we are to tackle climate change. Trees are felled for their wood as well as to clear spaces to plant crops to supply global food companies.At the climate change summit COP26 in Glasgow last year, more than 100 governments promised to stop and reverse deforestation by 2030.The latest satellite data from Brazil's space agency Inpe again calls into question the Brazilian government's commit...
National Trust to plant blossom trees in cities

National Trust to plant blossom trees in cities

Science
EPAThe National Trust is planning to plant dozens of blossoming trees, including cherry, hazel and plum, at different sites around the UK.As part of the plan, a circle of 33 trees will be planted in London, one representing each London borough. Designs are being finalised for groves in Nottingham, Newcastle and Plymouth - and other sites will follow.The project should help improve access to nature for those in towns and cities across the country.The idea is to try to create a UK equivalent of Japan's concept of "Hanami" - the annual celebration of flowers, and the coming of spring.Research carried out for the National Trust last year showed that almost half a million people live in "grey deserts " with no trees or green spaces nearby.Hilary McGrady, director general of the Trust, said the...
Scientists unlock Alpine trees’ molecular defence

Scientists unlock Alpine trees’ molecular defence

Science
Researchers have found a way to tackle a disease that threatens thousands of hectares of Alpine forests each year.Needle bladder rust causes Norway spruce needles to yellow and fall out, causing a significant reduction in growth.Scientists in Austria have unlocked a natural defence mechanism that the species can use to fend off the potentially fatal pathogen.The findings have been published in the BMC Genomics journal.Disease is one of the major threats facing trees around the globe, especially in a warming world where many organisms are finding themselves living in an environment in which they are under increasing levels of stress.It is widely predicted that invasive pathogens, and the insects that can spread them, are expected ...
Trees in forests all over the world are getting younger, shorter

Trees in forests all over the world are getting younger, shorter

Science
May 29 (UPI) -- Trees in forests around the world are getting younger and shorter as a result of human-caused climate change and other environmental stressors. New research, published Friday in the journal Science, suggests rising global temperatures and atmospheric CO2 concentrations over the last century, combined with an uptick in environmental stress and extreme weather events, have significantly altered the makeup of the planet's forests. Advertisement The changes have left old growth forests especially vulnerable. For the study, researchers recorded satellite measurements of global forests and completed a survey of the scientific literature on forest health over the last several decades. Their efforts showed increases in tree mortality have left many forests dominated by younger, sh...
