36 over 200 metres (or yards) from the dam and pendulous sedge and coltsfoot are among the colonisers. A 30-year old map shows stretches of open land here. Deser- ted ant hills under the canopy of thin trees and scrub are reminders of the rough grassland in which they once thrived. On to the horse-ride at Bellringers Hollow (or Pigs Bottom) where the sun came out and brought with it a peacock butterfly and a comma butterfly, which settled to give us a good, close view. Then westwards, upstream and uphill to the triangular "Reservoir Pond" at Goldings Hill. Its lower, arti- ficial bank is made of puddled clay.
