Protect habitats for amphibians
A before-and-after study in 1986–1999 of a pond within a housing development in Cambridgeshire, UK (Cooke 2000) found that pond protection during development did not prevent a significant decrease in common toads Bufo bufo, but resulted in an increase in common frogs Rana temporaria during the following ten years. Toad day counts decreased from 145–262 in 1990–1991 to 63 in 1999. Night counts showed a similar trend (240–434 to 59). However, numbers of frog egg masses increased significantly from 12 in 1990 to 96 in 1999. Development was undertaken in 1988–1989 and part of the largest of three breeding ponds was protected. The pond section was 375 m2, with a terrestrial margin of 5 m. Each spring, day and night pond counts were undertaken.
