Understanding seabird distribution patterns to design marine Important Bird Areas (IBAs)

Objectif

Marine Protected Areas (MPAs) are considered as a promising management tool under an Ecosystem-Based Management (EBM) approach. However, less than 1% of the oceans' surface is currently protected, and most MPAs are small and restricted to coastal areas, thus overlooking wide-ranging marine organisms which are key components of marine trophic webs (top predators) and useful monitoring tools of the anthropogenic impacts on the marine environment. Among these organisms, seabirds are conspicuous and provide an opportunity to study the influence of diverse variables (oceanographic, topographical, anthropogenic) to ultimately build predictive models helping to design and managing pelagic MPAs.

MARIBA will run in coordination with a LIFE project directed to design Important Bird Areas at sea (marine IBAs) in Spain, a first interdisciplinary step to create MPAs accounting for wide-ranging marine organisms. Within the study area, highly threatened seabirds such as the critically endangered Balearic shearwater Puffinus mauretanicus require fast conservation action to understand and reduce their threats at sea, and this project is addressed in this way. MARIBA will take advantage of the data available from this LIFE project (remote sensing, surveys at sea) to ascertain which are the main factors influencing seabird distribution, and ultimately to develop predictive models to properly design the marine IBAs.

A novel semi-experimental part of the project will compare seabird distribution between two fishing regimes (trawling moratoria vs. trawlers operating), to ascertain how trawling fisheries influence seabird distribution and, thus, how these activities should be regulated within the IBAs. Also novel for the region will be the consideration of food-availability descriptors at different scales (data on small pelagic fish distribution in parallel with seabird censuses).
