Report of the Working group on Improving use of Survey Data for Assessment and Advice (WGISDAA)

Over its three-year term the WG has been providing ad hoc advise to survey and advice working groups as requested. Predominantly these relate to survey WGs in this period as changes in the distribution of species and budget constraints have meant that the current survey protocols had developed deficiencies in relation to the assessment needs or survey effort required to deliver consistent information exceeded the availa-ble budgets, while assessments concerns were dominated by issues other than survey data.
