This report aims to provide an understanding of the evidence requirements for marine mammals in English waters, with a focus on cetaceans. This is to inform the requirements of further studies to provide evidence for natural capital assessments.
A review of monitoring projects for marine mammals within UK and English waters has been conducted to obtain data relating to marine mammals as an ecosystem asset. The review encompasses both government-funded evidence projects as well as wider monitoring by non-governmental organisations (NGOs) and citizen science projects.
