Diseased Trees To Be Felled At The National Trust's Barrington Court Estate

BARRINGTON , UNITED KINGDOM - MARCH 04: A tree surgeon on the ground cuts branches from a horse chestnut tree about to be felled after it was identified as being infected with bleeding canker, at the National Trust's Barrington Court on March 4 2009 in Somerset, England. A historic avenue of over 50 horse chestnut trees is being cut down and replaced with a variety of oak after the National Trust decided the trees had to go for safety reasons, as an infection of bleeding canker causes the trees to lose bark and branches and eventually die. The Trust has already had to cull a number of other horse chestnuts at properties around the country and experts at the Royal Botanic Gardens, Kew, have compared the problem to Dutch Elm Disease warning that conker trees are in danger of dying out in Britain unless more is done to control the disease.
