A partial regulatory impact assessment that included an estimate of costs and benefits was prepared and included in the consultation on proposed changes to the bird registration scheme. This consultation took place between November 2006 and February 2007. My Department will prepare an impact assessment for amendments made to species listed on Schedule 4 and associated regulations under section 7 of the Wildlife and Countryside Act 1981. The cost to DEFRA of administering the current scheme is estimated at £350,000 per year, plus approximately £100,000 in costs in administrative burdens. This does not include any enforcement costs.
