The bittern – one of the UK’s greatest bird conservation priorities – will have an uncertain future in Britain if more is not done to protect this wetland bird from the ravages of climate change and sea level rise.

The UK bittern population - which is currently growing following near collapse in 1997 - is heavily dependent upon a stronghold in freshwater reedbeds along the Suffolk coast. However, delegates at a conference today will hear how these sites are vulnerable to sea-level rise, once more putting the future of this bird, and other rare reedbed wildlife, in jeopardy in the UK.

Dr Mark Avery, the RSPB’s Conservation Director, said: “The UK bittern population is heavily dependent on young birds being produced at a few sites on the Suffolk coast, especially the RSPB’s Minsmere reserve. Alarmingly, all of these freshwater sites are highly vulnerable to flooding by seawater as sea levels rise.

“Bitterns provide a valuable test case to develop our understanding of how to help wildlife adapt to the threats imposed by climate change, giving us an early warning of the fate that may await the rest of our native wildlife. If we fail the bittern, what hope is there for other wildlife in the future?

“Together with our partners such as Natural England, we must re-double our efforts to make existing reedbeds as suitable as possible for threatened reedbed wildlife like the bittern. In addition, a substantial area of new reedbed will urgently need to be created away from the coast, and the threat of climate change-driven, sea level rise. We know it takes at least ten years for a newly created reedbed to support nesting bitterns; but don’t know how long existing sites will be able to survive against the ravages of climate change.”

Sir Martin Doughty, Chair of Natural England said: “We successfully managed to stave off national extinction for a second time in the 1990s and last year we recorded over 50 booming males. These recent gains are clearly still at risk, especially with the threat of sea level rise, tidal surge and coastal erosion.

“At Natural England, we are working with the Environment Agency and others, to create alternative reedbeds inland, for example, through the Great Fen Project. The National Nature Reserve at Walberswick, is another important site for bitterns - one of a number of sites where Natural England staff support and monitor the fragile bittern population.

“Natural England supports a more sustainable approach to managing the coastline not only for bittern but also for the entire range of wildlife on the coast. We want to see rapid progress towards managed-realignment in both coastal and fluvial environments, including the creation of managed washlands and wetlands in appropriate locations. The future lies in creating more sustainable reedbeds inland away from the eroding coastline. We need to take urgent action now.”

Extinct in Britain between 1886 and 1911, the bittern reached a second low point in 1997, when the bird’s population dropped to 11 males. However, 10 years on, surveyors from the RSPB and Natural England recorded a minimum of 51 male bitterns across 33 sites, giving encouragement to everyone involved with the conservation of this bird. Last year’s total was a 16 per cent increase on last year’s figure of 44 males, and only four behind the recent record of 55 males in 2004.

Editor’s notes:

1. Natural England works for people, places and nature to conserve and enhance biodiversity, landscapes and wildlife in rural, urban, coastal and marine areas. We conserve and enhance the natural environment for its intrinsic value, the wellbeing and enjoyment of people, and the economic prosperity it brings.
2. The RSPB is the UK charity working to secure a healthy environment for birds and wildlife, helping to create a better world. The RSPB is the UK partner of BirdLife International, a global partnership of bird conservation organisations.
3. The Boom or Bust (A sustainable future for reedbeds and bitterns) conference takes place today (Tuesday 4 March, 2008) in Doncaster.
4. A joint RSPB/ Natural England programme, funded through Natural England’s Action for Birds in England, has been responsible for monitoring the numbers of UK booming male bitterns every year since 1990.
5. When establishing a territory, male bitterns utter a call a little like the sound of a foghorn. This ‘booming’ call can be heard up to three kilometres away.
