One of the key measures of success of the project is numbers of little tern chicks, adults and fledglings across project sites in each year. In order to ascertain this we have introduced a monitoring programme with the aim of recording breeding numbers and successes. At the end of the first and second seasons’ sites produced Annual Site Breeding Reports which were analysed by the project’s technical group. The sites are informed of findings allowing them to modify their site management for the following season.
