‘Redlist’ report launched on Jersey’s bird populations in the 21st Century
This week sees the launch of a major new study into the conservation status of Jersey’s bird populations. The sixteen page report is the result of a collaboration between Durrell Wildlife Conservation Trust, The States of Jersey Department of Environment and the Société Jersiaise.
The project has taken over three months to complete using information gathered locally and statistics from the British Trust for Ornithology, the Joint Nature Conservation Committee, the Royal Society for the Protection of Birds and the Wildfowl and Wetlands Trust. Data collated over the past twenty years has been analysed and trends for the population of every bird species recorded in Jersey established and used to assess levels of threat to each one.
Commenting on the study one of the authors Durrell’s Dr Glyn Young said; “Bird monitoring provides one of the most robust and globally recognised methods for measuring changes in the state of biodiversity and the broader environment. This is the first such assessment of Jersey bird populations and the criteria used are intended to ensure that Conservation Status of Jersey’s Birds listings reflect each species’ global and European status as well as that within Jersey.”
The study segments the birds by category and the criteria used to determine each species’ conservation status is based on those used by similar studies conducted by UK conservation organisations. Three traffic-light colours; red, amber and green are used to indicate the level of threat to each bird in Jersey. Red listed species (33 species including the likes of puffin and cuckoo) are those that have undergone severe declines and are now in real danger of disappearing from Jersey; amber species (50 like tufted duck and herring gull) have declined markedly but are not yet considered in danger of local extinction or, like peregrine and sand martin, are very localised and vulnerable to changes to their small sites; 52 green species are, like wood pigeon or blue tit, still common and secure.
John Pinel of the States of Jersey Environment Department said “This document provides a powerful tool with which to focus conservation efforts. It can be used for a variety of purposes, not least when justifying sites of special interest but also in considering the future development of the Island.”
Co-author Mick Dryden Chairman of the Société Jersiaise added “Many sites across the Island are managed specifically to protect birds and other wildlife. Ownership of this land is in many different hands but all work to secure a future for our bird species”
Two thousand copies of the report have been published, thanks to generous support from the Channel Islands Co-operative Society, and copies are available free of charge in hard copy or in electronic format below.
