Bird numbers plunge to 44-year low after dramatic habitat loss and harsh winterPopulations of breeding birds on farmland in
England are at their lowest levels since formal attempts to monitor them began in 1966, the government said today. The figures suggest overall populations have fallen by more than half in the past 44 years.Although the most recent annual decline of 5% might be down to a cold winter and recent changes to farming practice, experts believe the long-term trends caused by continuing pressure on habitats mean most of the 19
species surveyed are in trouble. Figures for the last five years suggest a 10% decline and since the most recent ones are based on 2009 observations, the cold 2010 winter weather may bring further bad news next year.The significant falls last year included kestrels (down 27%) lapwings (12%), grey partridge (23%), skylarks (5%) and starlings (20%). Relatively small percentage falls may still have huge impact because of low numbers in the first place.The figures for England are based on the annual breeding birds survey by the British Trust for Ornithology, in which volunteers check 3,200 randomly selected 1km squares around the
UK twice each year. But other data is included in the index published by environment department Defra, which makes figures for species decline slightly different. These figures are not yet online.Twelve of the 19 species monitored had falling populations. The 2009 index is the first since the European Union stopped ordering crop farmers not to use part of their land for agriculture, a measure first introduced in the 1990s to stop over-production but suspended because of high grain prices. Although UK farmers are still encouraged to seek subsidies to "green" their land through the UK's entry and higher level environmental stewardship schemes, there are fears these may fall victim to the looming austerity cuts.David Noble, a principal ecologist with the trust, said the latest index published by the Departme ...
