Greater London Bat Action Plan
Long-eared Bats © Mike Waite
"The individuals which are so common in South London, even in thickly populated neighbourhoods like Battersea and Chelsea and Vauxhall, must, I think, be principally the pipistrelle…We see it from the spring months until the early winter, both in our open spaces and in the busy street" (Johnson, 1930)
This Action Plan is dedicated to the memory of Pete Guest, former Chair and leading light of the London Bat Group, who achieved so much for bat conservation in London before his sad and untimely death in late 2003. Aims To reverse the current population declines in London's bats. To redress Londoners’ misconceptions about bats and secure their status as culturally valued species. Introduction Bats are highly adapted nocturnal mammals – the only mammals to have evolved powered flight. Often thought of as flying mice, they are in fact more closely related to humans than to rodents, and form a special group of their own: the Chiroptera, meaning ‘hand-wing’. Bats are generally only seen briefly at dusk and their seemingly furtive nocturnal habits have, over generations, resulted in popular misconceptions and even a misplaced fear of them. Modern horror stories, films and the media quoting fiction as fact have not helped to improve this tainted public image. British bats only eat insects. Serving as natural insecticides, they consume huge numbers and variety of prey – a single pipistrelle can eat 3000 midges in a night. With the loss of natural roost sites in trees and woodlands, many bats have adapted to living in buildings. Some favoured Londoners may therefore be surprised to discover these unexpected lodgers for a short period during the summer, when female bats need somewhere warm to raise their young. Their reliance on buildings for roosting greatly focuses conservation efforts on people's tolerance and goodwill. Bats are an excellent indicator of the quality of our environment, as their complex ecological requirements leave them highly sensitive to environmental changes. Their serious decline should be of major concern to us all. All of London's bat species are dealt with collectively in this plan because: Those currently concerned with the conservation of bats deal with all species; All bat species and their roosts are equally protected by law; The conservation problems faced by all bats are believed to be generally similar, so measures proposed here are likely to be of benefit to a number of species. Current Status At least eight species are known to be breeding in Greater London (see Species Audit in the Annex). The two pipistrelles are by far the most common and still occur in all London Boroughs. The noctule and Daubenton’s bats are regularly recorded and widespread. Little is known about the current status of most species nationally, although the available evidence suggests an overall decline in populations. Both the common and soprano pipistrelles are thought to have declined by an estimated 70% between 1978 and 1993 (Harris et.al., 1995). A recent repeat survey in London found that there has been a statistically significant decline in the bat population of Greater London since the mid-1980s, particularly for the noctule, Leisler's bat and the serotine (Guest et al., 2000). Further information on the status of London’s bats can be found in the Annex. Specific Factors Affecting the Species 4.1 Loss of maternity roost sites in buildings or trees Destruction of, disturbance or damage to vulnerable maternity roosts can result from a lack of public awareness and understanding of bats, as well as ignorance of the legislation protecting them. 4.2 Loss of and disturbance to other roost sites Hibernation and other seasonal roost sites can be disturbed or damaged for the same reasons as above. These sites include buildings (mainly their roof spaces), trees, bridges and various underground structures, such as cellars, tunnels and disused mines. 4.3 Loss of feeding habitats Changes in land use can result in the loss of insect-rich feeding habitats such as wetlands, woodlands and grasslands. 4.4 Disturbance to commuting routes Flight paths to and from feeding areas and roosts may be disturbed through the loss of flight line features such as green corridors, or through introduction of new features such as artificial lighting. Current Action 5.1 Legal status All species of bat are protected in the UK on Schedule 5 of the Wildlife and Countryside Act, 1981 (as amended by the Countryside and Rights of Way Act, 2000), and on Schedule 2 of the Conservation (Natural Habitats &c.) Regulations, 1994. The latter further implements European legislation protecting bats. Bats are also protected from cruel ill-treatment by the Wild Mammals (Protection) Act, 1996. The UK is a signatory to the Agreement on the Conservation of Bats in Europe which came into force in 1994, set up through the Bonn Convention on the Conservation of Migratory Species of Wild Animals, 1979. While this is not strictly a legal instrument, as a signatory the UK is obliged to abide by such agreements. 5.2 Mechanisms targeting the species These current actions are ongoing. They need to be supported and continued in addition to the new action listed under Section 7. 5.2.1 Bat wardens The London Bat Group co-ordinates a network of licensed bat wardens, working in liaison with English Nature to safeguard bat roosts, particularly in houses. 5.2.2 Awareness-raising The place of bats in London life is promoted regionally, locally and London-wide by organisations such as the London Bat Group, London Wildlife Trust, the Wildfowl and Wetlands Trust at Barnes, and Local Authorities through a programme of guided walks, illustrated talks, training and articles. The Bat Conservation Trust, English Nature and the London Bat Group have produced various publications, including a series of specifically targeted leaflets aimed at promoting best practice in relation to bats within the building, pest control and arboricultural professions. 5.2.3 Survey and Research London Bat Group volunteers participate in national and local surveys and research, including the Bat Conservation Trust’s National Bat Monitoring Programme. Objectives, Actions and Targets Most of these actions are specific to this species. However, there are other, broader actions that apply generically to a number of habitats and species. These are located in a separate ‘Generic Action’ section which should be read in conjunction with this document. There are generic actions for Site Management, Habitat Protection, Species Protection, Ecological Monitoring, Biological Records, Communications and Funding. Please note that the partners identified in the tables are those that have been involved in the process of forming the plan. It is not an exclusive list and new partners are both welcomed and needed. The leads identified are responsible for co-ordinating the actions – but are not necessarily implementers.
Objective 1 To raise awareness among key audiences, specifically planners, land managers and tree contractors Target: Disseminate best practice advice by 2006
Objective 2 To increase knowledge of bat distribution and population change Target: Monitoring programme implemented by 2005; collation of existing data completed by 2004
Objective 3 To protect and create new artificial roost sites in association with suitable feeding habitat Target : Establish 40 new roosting opportunities by 2006
Objective 4 To increase public awareness of and involvement in bat conservation Target: 10 licensed bat workers by 2005; 6 Hibernation Licence holders by 2006; 1 Training Licence Holder by 2005
Objective 5 To make a significant contribution to urban bat conservation through new ecological research Target: One research topic completed and disseminated by 2008

Annex London Bat Audit
Data Limitations This audit is based on data from the London Bat Project collected in the mid-1980s, as well as that collected since by the London Bat Group and is therefore not systematic. This audit is the best possible understanding of the status of bats in London that can currently be realised by the London Bat Group. In general, every borough will have bats present, as even in the inner boroughs there are usually some areas of suitable habitat that can provide feeding habitat for small numbers of at least the common pipistrelle species. In general, the outer boroughs with larger areas of more suitable habitat should be expected to have higher numbers of bats and a greater diversity of species. ContactThe Lead for this species is the London Bat Group. Please note that although the London Bat Group will co-ordinate these actions on a London-wide scale with the support of the Partnership, it unfortunately cannot currently resource action at a Borough or Local Level.
