February 17th, 1999

The annual cross-country run took place on the 12th and, as usual, I walked down to the bridge, overlooked by the viaduct, where the runners Dutch Elmfirst cross the Went. I enjoy standing in this spot once a year as there are lots of things to be seen.

For example, one section of the hedgerow contains some very distinctive twigs. TheseDutch Elm look like any other twig towards the tips but, lower down, the bark grows outwards to form wings or flanges, making them look quite unusual. At first sight, it might be thought Dutch Elmthat the strange growth is caused by a viral infection, as happens in some other plants, but it is actually quite normal for Dutch elm. Large elm trees have disappeared from the area around Ackworth because of the effects of Dutch elm disease but elm survives in some locations, such as Hessle Common, as a hedgerow plant. In one or two places, specimens have been allowed to grow into trees but they areDutch Elm now reaching the size at which they can be expected to become the second generation of elms to fall victim to the disease.

During my stand at the bridge, I also heard the 'zeet zeet' call of a willow tit and managed to spot it in a hawthorn hedge, where it was feeding with some bluetits and great tits. Willow tits are quite easy to find locally but are not normally found inside the school grounds. Other sightings made at the bridge were of a water vole swimming in the Went and a heron flying over.
