Grand CommitteeTo ask Her Majesty’s Government what steps they are taking to counter the decline in songbird numbers and the threat that invasive non-native species pose to such birds.
My Lords, I declare my interests as listed in the register. As I cannot do it later, I thank all noble Lords who will be speaking. The fact there are so many is testimony to the importance of this matter.
I wish to highlight the plight of the UK’s often forgotten passerines, more commonly known as songbirds, or little brown jobs—LBJs—to the bird-watching community. We do not hear much about the problems faced by many of our LBJs, as they are not spoken of in the same hushed, reverent tones used to describe our “iconic” birds of prey, charismatic seabirds or enigmatic waders, wonderful though they are. LBJs are those that delight many of us on our back-garden feeders and nesting boxes and on farms or other landholdings. They range from the cheeky house sparrow—once a common sight wherever we chose to live in our cities, towns and countryside—and the glorious skylark with its uplifting song of pure liquid gold, immortalised by Shelley and Vaughan Williams, through to the suite of summer migrants, such as the nightingale and other warblers that fill many a wood, glade, marsh and reed bed with the glorious dawn chorus, the avian sound of spring and summer.
The numbers of many of our most cherished and emblematic songbirds have crashed or declined alarmingly in upland, farm and woodland landscapes since systematic records of their numbers began to be compiled in the late 1960s and early 1970s. As examples, house sparrows, song thrushes, skylarks, spotted flycatchers and corn buntings are all down between 50% and 90%, depending on the species. Worst of all, the turtle dove is almost certainly doomed to extinction, with 98% gone in less than two generations. Overall, our farmland bird populations have declined by 56% and our woodland birds by almost a quarter over this period.
Since the rapid decline in the 1980s, efforts have been made to arrest the trend. Over 70% of England’s farmland is under countryside stewardship schemes, 7.2 million hectares of UK land is managed to benefit wildlife, and the size of broadleaf woodlands is increasing. Hundreds of millions of pounds have been spent on environmental stewardship agri-environment schemes, or AES, and woodland grants. This has been backed by millions of pounds of donations spent by NGOs and some tremendous work by farmers given freely. Given that, this debate should be celebrating a rise in the songbird population, but it is not. My noble friend will doubtless highlight some of the successes but he will be the first to agree that the songbird decline continues remorselessly, year on year. We must ask why this help has not delivered as expected.
Many of our farm and woodland ecosystems are currently unbalanced. In stark contrast, the results achieved by the Allerton Project—scientific research by the Game & Wildlife Conservation Trust over 25 years on a farm in Leicestershire—show a different and better way forward. Improving the habitat combined with good management, including sufficient all-year food supplies and targeted predator control, have not only allowed both the arable land and woodlands to be improved in condition, while remaining profitable, but benefited a whole range of wildlife, not just songbirds. The problem for farmers in England, in stark contrast to the more enlightened regime in Scotland, is that the current AES cover only habitat. The project has demonstrated conclusively that good management is needed as well.
In the absence of the apex predators, which mankind eliminated, it is our duty to intervene to maintain balanced ecosystems and accept responsibility for managing wildlife, just as we did successfully until the latter part of the 20th century. Such a policy still works well in other countries, and the Government and NGOs have recently employed it to good effect in South Georgia. The results of the project are a winning blueprint for farming, wildlife and the environment, and thus for us. Will my noble friend use this template when bringing forward proposals for the new farming regime that is needed soon?
In urban areas, our gardens are habitat havens for all-year resident LBJs, as well as for migratory and seasonal visitors. With the huge pressure for new homes, will the Government ensure that detrimental proposals such as the Mayor of London’s “grab a garden” for development planning guidelines, which have so little thought for wildlife, are blocked? While on planning, has my noble friend pressed MHCLG to impose a buffer zone of 400 yards against any new development around sites where species of conservation concern nest, to protect them from irresponsible humans, their dogs and especially cats? I have spoken twice recently about cats. I merely add that, of the 29 predators of songbirds, cats are the worst, killing about 55 million songbirds annually, but should be the easiest to control. I merely say that I thought my noble friend’s recent letter to me on this was peely-wally. There is scientific evidence that predation by cats is having a real impact on bird populations. The very least the Government should do is proactively support the efforts of charities such as SongBird Survival, which is working to mitigate it.
I welcome and have encouraged the planting of more broadleaf woodlands. However, as Robbie Burns wrote,
“The best laid schemes o’ mice an’ men
Gang aft agley”.
Due to poor management, they have become safe havens for our already too numerous predators and inevitably have provided more trees for grey squirrels—a non-native invasive species—to gnaw. As broadleaf woodlands can support some eight to 18 squirrels per hectare, we have helped them considerably. In addition, they are very bad news not only for our native red squirrels but also for our nesting songbirds. Ring-necked parakeets outcompete native songbirds and other hole-nesting birds for nesting spaces and at garden feeding stations. It is a sad indictment that the most commonly encountered mammal in our royal parks, just a few hundred yards from here, is that destructive grey squirrel, and that the dominant birdsong and call heard there is that of the domineering ring-necked parakeet. They are both overabundant, oversexed and over here.
Returning to habitats for birds, rhododendron ponticum growing wild is a particular issue for ancient and native woodland. It results not only in the loss of native plants and a decrease in bird diversity but also in reduced populations of woodland species. Muntjac and fallow deer destroy the understorey and vegetative layer that the threatened native nightingale, wood warbler and other nesting birds rely on.
In 2010, the estimated annual cost of alien species to the British economy was £1.7 billion per annum. For comparison’s sake, that is about the same as the Foreign and Commonwealth Office’s budget for that year. On page 63 of their report, A Green Future: Our 25 Year Plan to Improve the Environment, when referring to non-native invasive species, the Government state:
“Where it is not feasible to eradicate these species because they are too widely established, we will seek to neutralise their threat by managing them effectively”.
What policies does my noble friend have in mind for these species and, just as importantly, what are his policies to mitigate the arrival and establishment of other species? Page 57 of the same document states that HMG will,
“support nature’s recovery and restore losses suffered over the past 50 years”.
That must apply particularly to songbirds.
We are an urban-oriented population, much of whose knowledge comes from books, the internet and television rather than from hands-on experience. If the Government are serious about protecting our environment, which includes the songbirds, they must heed more the advice of farmers and landowners, and the AES should be based on the Scottish model. Furthermore, would my noble friend agree that a substantial programme of education is needed, including active support for those NGOs already working in this field, as too many wildlife programmes are tainted by the syrupy anthropomorphism of celebrity presenters who deny the reality of rural life?
