Drought scuppers hopes for wetland birds

20.07.2005


Once common wading birds in south-east England look set to be amongst the casualties of this year’s drought.



Numbers of successful breeding lapwing, redshank and snipe have dropped by up to 80 per cent at five RSPB reserves in Sussex and Kent. At Brading Marshes, an RSPB reserve on the Isle of Wight, low spring and summer rainfall has left land parched. Redshanks have gone completely while just one pair of lapwing remains.

The news comes just a week after Southern Water extended its hosepipe and sprinkler ban across most of Sussex. Last winter was the second driest since 1904 in the south-east and rainfall in each of the last eight months has been well below average.


Phil Burston, Senior Water Policy Officer at the RSPB said: “Some of the birds affected are already just clinging on in the areas where water shortages are most severe. If we do not cut our water consumption, drought orders will be imposed and these birds will suffer even more.

“The south-east is undoubtedly drying up. To save our wetlands, our wildlife and the livelihoods that depend on them, we must stop wasting so much water in our homes and gardens, build houses to the highest water efficiency standards and force water companies to immediately address their shameful rate of water leakage. Failure to do this will see our wetlands ruined and billions of pounds squandered on unnecessary new reservoirs and desalination plants.”

Wading birds need boggy grassland or damp meadows in which to nest and find their insect food.

Their numbers have tumbled in the last 25 years, particularly in lowland areas. The most recent survey (Breeding waders and wet meadows 1982-2002) found that in south-east England snipe numbers were down 96 per cent to just ten pairs, lapwing down 61 per cent and redshank down 42 per cent.

Numbers of both lapwing and redshank had begun to recover on RSPB reserves because of high quality wetland management. But winter and spring drought this year has left even those sites much dryer, reversing recent successes.

Drought in North Kent could also affect waders for several years to come. Cracks will develop in arid land and another dry winter will prevent the regeneration of suitable breeding habitats for next spring. “It’s a disaster waiting to happen,” said Alan Johnson, Site Manager of seven RSPB reserves in North Kent. “If we get too little winter rain the cracks will not close and what rain there is will just seep through instead of staying on the surface and creating the boggy sites that waders need.”

The RSPB believes the construction of thousands of new homes in the UK’s driest areas, and the subsequent demand for water, could seriously damage hopes of saving the south-east’s breeding waders.

Phil Burston said: “We have all become profligate with our water use yet could annually save ten billion litres of water, and our wetland wildlife, if these new homes were built to the highest water efficiency standards and if existing properties had water-saving devices installed.

“It would be a tragedy if we were to lose these birds just as they are beginning to return. Climate change and water shortages pose a very real threat but action now by government, house builders and water customers could save our beautiful wetland heritage, the charismatic wildlife that depends on it, and reduce thousands of annual water bills at the same time.”

Site by site:

Northward Hill, Kent, and Hoo Peninsula
Numbers of lapwing at Northward Hill RSPB Reserve have dropped by 80 per cent from 31 breeding pairs to six this year. Redshanks are also disappearing, their numbers down from 34 pairs to 11. Across the 5,000-hectare Hoo Peninsula in North Kent, which includes three wet grassland RSPB sites, just 60 of the 169 breeding lapwing pairs are left.

Pulborough Brooks, West Sussex
At Pulborough Brooks RSPB Reserve in the Arun Valley, close to the half-full Weir Wood reservoir, just one pair of lapwings has produced chicks compared to ten pairs in a normal year. Usually, at least six redshank pairs breed; this year just one has been successful.

“Our biggest worry is that the areas waders use are shrinking,” said Pete Hughes, Warden at Pulborough. “Declines may be less obvious here but as the flood plain dries out there are fewer and fewer places where they can nest. We are desperately trying to keep a few areas wet which means waders are more vulnerable because they are being forced into just one or two places.”

Brading Marshes, Isle of Wight
The picture is the same at Brading Marshes RSPB Reserve. “This has been a disastrous year for breeding waders,” Warden Keith Ballard said. “The water table is metres below the optimum. If we had had the expected rain earlier this year we would undoubtedly be attracting many more waders including snipe.”

Im Focus: Making lightweight construction suitable for series production

More and more automobile companies are focusing on body parts made of carbon fiber reinforced plastics (CFRP). However, manufacturing and repair costs must be further reduced in order to make CFRP more economical in use. Together with the Volkswagen AG and five other partners in the project HolQueSt 3D, the Laser Zentrum Hannover e.V. (LZH) has developed laser processes for the automatic trimming, drilling and repair of three-dimensional components.

Automated manufacturing processes are the basis for ultimately establishing the series production of CFRP components. In the project HolQueSt 3D, the LZH has...

Im Focus: Wonder material? Novel nanotube structure strengthens thin films for flexible electronics

Reflecting the structure of composites found in nature and the ancient world, researchers at the University of Illinois at Urbana-Champaign have synthesized thin carbon nanotube (CNT) textiles that exhibit both high electrical conductivity and a level of toughness that is about fifty times higher than copper films, currently used in electronics.

"The structural robustness of thin metal films has significant importance for the reliable operation of smart skin and flexible electronics including...

Im Focus: Deep inside Galaxy M87

The nearby, giant radio galaxy M87 hosts a supermassive black hole (BH) and is well-known for its bright jet dominating the spectrum over ten orders of magnitude in frequency. Due to its proximity, jet prominence, and the large black hole mass, M87 is the best laboratory for investigating the formation, acceleration, and collimation of relativistic jets. A research team led by Silke Britzen from the Max Planck Institute for Radio Astronomy in Bonn, Germany, has found strong indication for turbulent processes connecting the accretion disk and the jet of that galaxy providing insights into the longstanding problem of the origin of astrophysical jets.

Supermassive black holes form some of the most enigmatic phenomena in astrophysics. Their enormous energy output is supposed to be generated by the...

Im Focus: Microprocessors based on a layer of just three atoms

Microprocessors based on atomically thin materials hold the promise of the evolution of traditional processors as well as new applications in the field of flexible electronics. Now, a TU Wien research team led by Thomas Müller has made a breakthrough in this field as part of an ongoing research project.

Two-dimensional materials, or 2D materials for short, are extremely versatile, although – or often more precisely because – they are made up of just one or a...
