HC Deb 12 January 1993 vol 216 cc690-2W
Mr. Ron Davies

To ask the Secretary of State for Wales if he will list the sites of special scientific interest damaged by acid rain in the latest year for which figures are available and give the hectarage of each site of special scientific interest affected.

Mr. David Hunt

A study published in October 1992 identified 42 sites of special scientific interest in Wales as having freshwater habitats affected by acid deposition, out of a current total of 848 SSSIs. These sites are listed in the tables. The area given is that of the whole SSSI and not the area damaged. The study sampled freshwaters and did not assess damage to the land area of sites. The Countryside Council for Wales is currently seeking to establish how far land habitats are being damaged by acid rain. Present research has indicated that some parts of south Wales may also be affected by acid rain although this was not considered likely at the time of the original study.

Welsh SSSI surveyed and within which freshwaters were considered to have been affected by acidification.
