✦ Synopsis

  1. Of the 41 564 small water bodies (`ponds') identified on Ordnance Survey maps of Cheshire in ca 1870, 61% had disappeared by the early 1990s.

  2. Pond loss has taken place across the county and is associated with a number of different replacement land-uses; loss rates are highest in areas of urban development.

  3. Using aerial photography, only 45% of extant ponds show areas of open water, many being completely overshaded by trees or with substantial emergent vegetation.

  4. The effects of pond loss are now being felt in increasing fragmentation of the total resource; the density of wet ponds over the entire county has fallen from 17.8 km 72 (ca 1870) to 3.25 km 72 (1992/ 93), and the `connectedness' of the pond landscape has been similarly reduced. #1997 by John Wiley & Sons, Ltd.

  5. to establish the numbers of ponds by a census, using maps and aerial photography; 2. to establish, in the broadest terms, their current status; 3. to identify causes of their disappearance.

We believe this to be the first comprehensive census of a dense regional pond network, pond-by-pond, though other surveys (e.g. have been carried out at a more generalized level using tetrads.

1. Sample areas of the county were used to estimate pond loss. An extensive survey used only maps while a smaller, intensive survey combined maps with a field study. In total, 283.43 km2 were surveyed, approximately 7% of the total area. 2. Fifty-five per cent of the ponds present in 1870 had disap
