HC Deb 26 March 1987 vol 113 c221W
Mr. Peter Bruinvels

asked the Secretary of State for the Environment what information he has as to the number of swans that have died as a result of lead shot poisoning in each of the last three years; and if he will make a statement.

Mr. Waldegrave

It is estimated that 3,000–3,500 mute swans died each year from this cause in the period 1980–85. The estimate is derived by relating details of post-mortem examinations carried out at a number of centres to the known annual mortality rate of the population as a whole. It is too soon to assess the effects of the recent statutory ban on the sale of certain lead angling weights, but the Nature Conservancy Council will monitor the position.
