glory - but are London's trees dying? | |
Tree threatBleeding Canker
is threatening London's Horse Chestnut trees. Horse Chestnut trees are an
iconic part of the capital's landscape and give us our much loved traditional
game of conkers. But disease is now threatening the trees' survival. The
drought in Summer 2006 has left the trees weak and susceptible to attack by the
leaf minor moth. Worse still, they have become prone to bleeding canker.
The moth is ravaging the horse chestnut leaves, while the canker is causing
pussy sap lesions on their trunks. Inside Out London talks with tree experts
Andy Tipping, Head of the London Tree Officers' Association and Todd Longstaffe-Gowan,
Gardens Advisor to Historic Royal Palaces, about the history of this majestic
tree and the impact these diseases will have on London. Under threatAndy
Tipping is responsible for recording the health of many of the Horse Chestnut
trees and does so by giving the tree, a sort of 'pregnancy test'. A fragment
of the lesion is mixed with alcohol and then a small amount is tipped into a testing
device which displays the result. While the Horse Chestnut is not native
to Britain, it has become almost naturalised. "They are the largest
flowering trees, and are evocative of the English countryside," says Todd. Crushing
Conker newsConker fights, now banned by several schools due to concerns
over health and safety, are also under threat if these beautiful trees are eaten
away by disease. | Conker
crisis - smaller and fewer conkers this year |
Already their
large green leaves are falling early, and conker aficionados are reporting fewer
and smaller conkers this year. One conker fan noted that they "are
coming down earlier than they should, and the conkers have been quite small". For
many old and young conker fighters these diseases are troubling. "London
without its conker trees would be a sad place," said one contestant at Camden's
Conker Championship. Watch Inside Out London on October 23 to find out
more about how these diseases are affecting London's Horse Chestnuts. Links
