Guernsey - noted that the principle hedgerow tree is the Elm, and the island's management of Dutch Elm 

 Disease is unique in Europe; by law, all infected trees are felled and burned each year, at no expense to 

 the landowner; there is an excellent free tree replacement scheme and as a result, the disease has been 

 contained; consequently there are frequent sightings of the Goat Moth larvae and adults are seen at m/v 

 lights each summer, T.N.D. Peet, 1988(100):23.
