AEWA Waterbird Trend Analysis: Methodology Review 2021

Freshwater Marine Terrestrial Unclassified

Abstract

The Agreement on the Conservation of African-Eurasian Migratory Waterbirds (AEWA) is an intergovernmental treaty focussed on the conservation of migratory waterbirds and their associated habitats across their entire migratory range. AEWA produces a Conservation Status Report (CSR) every three years, which includes an assessment of waterbird population trends.

The work reported here provides a review of the existing approach for assessing the waterbird population trends, and explores the development of an alternative statistical approach.

The report is presented in two parts: (i) an introductory document which sets out the context and scope of the work; and (ii) the main statistical report.
