The use of monitoring data from north-west Europe as indicators for the health of Arctic-breeding waterbird populations

Author:

Published: 2025

The Arctic is warming faster than anywhere on the planet. Substantial ecological changes are occurring such as habitat loss and disruption to ecosystems. It is therefore urgent to better understand Arctic biodiversity to develop effective conservation strategies, yet such vast remote areas are challenging places to monitor, both practically and financially. As a solution, this study uses monitoring data from Arctic-breeding waterbird species on their wintering grounds to indicate potential changes occurring further north in the Arctic.

BTO Northern Ireland Marine Bird Evidence Review 2024: marine bird spatial use in the Celtic Seas

Author:

Published: 2025

This report was commissioned by the Northern Ireland Environment Agency to scope the evidence available on the movements and spatial distributions of certain marine birds in and around Northern Ireland waters, in order to identify knowledge gaps. The focus is on 37 marine birds found offshore, away from the coastline, that utilise the Celtic Seas (OSPAR Region III) and Ireland Exclusive Economic Zone marine environments. Metadata from 10 different sources (including directly contacting researchers, a literature review and accessing several archived datasets) are used.
