Conservation volunteers work with Europe to defeat elm disease



On Saturday Claire Young (right) joined members of the Wapley Bushes Conservation Group to plant new elm trees on Dodington Parish Council land.

Over the last few decades Dutch Elm Disease, a fungus spread by bark beetles, has devastated the British elm population to the extent that many people have never seen a live mature elm tree.

Now however a multinational project involving Wapley bushes may hold the key to repopulating elms in the UK. Members of the Wapley Bushes Conservation Group discovered a a native Wych Elm on the reserve that has remained unaffected by the disease, and they have have sent seeds from to the French national State Forestry Nursery for analysis to assess the extent of disease resistance.

The aim of the European project is to identify types of elm that are resistant to the disease so that eventually the resistant specimens can be planted out to repopulate the European countryside and help the many species that are dependent upon elms.

Tim Fairhead (also pictured above) of the Conservation Group explains “In return we received seeds from ancient elm trees in a French Nature Reserve, and these were grown on at Portsmouth University. These particular trees contain high levels of unique bark compounds that deter feeding by the beetles so they are less likely to get infected in the first place. We hope these trees will go on to provide a resource and home for threatened and vulnerable species like the White-letter Hairstreak butterfly”

This is the only elm repopulation project of its type in the South West and one of only four sites in the UK.
