Oh Jim, that was so very kind of you to help the injured grebe.
Yes, I've noticed quite a bit of tree-planting around the edges of fields, but no-one seems to be reducing field size. We get gigantic combine harvesters here, and they need massive fields. The hedges seem to be mainly hawthorn, a good choice for winter berries. However, near our village the farmers are now leaving broad belts of cover around the edges of their fields, and even putting in sunflowers and other flowers for seeds for wildlife.
