HC Deb 29 April 2004 vol 420 cc1201-2W
Mr. Kidney

To ask the Secretary of State for Environment, Food and Rural Affairs what recent assessment she has made of the likely effects of climate change on the UK's biodiversity in respect of insects, including butterflies; and what measures she proposes to take to counter such effects. [165308]

Mr. Bradshaw

The Department, along with the Devolved Administrations, statutory nature conservation agencies and non-governmental organisations, is contributing to an on-going research programme on the impacts of climate change on biodiversity in the UK. Results suggest that as climate changes, the distribution of species and the composition of habitats will change. With warmer temperatures, some northern species are likely to retreat, while southern species may he able to expand their ranges. At the same time, coastal habitats will be affected by rising sea levels. On land, movement of some species may be impeded by our fragmented landscapes, possibly leading to local extinctions. However, there is already evidence that some butterfly species have expanded their ranges northward in recent years.

The Government's existing policies for nature conservation provide the basis to mitigate the effects of climate change on biodiversity, by protecting and restoring wildlife habitats and concerted action to reverse the decline of threatened species. New evidence from research and monitoring is taken into account in developing these policies and management strategies. However, there remains considerable scientific uncertainty about the implications for individual species.

The Government are fully committed to the Kyoto Protocol and to reducing the UK's greenhouse gas emissions. Through the Climate Change Programme we have put in place a strong programme of policies and measures to ensure that the UK meets its commitments under the Kyoto Protocol and moves towards its domestic goal of reducing carbon dioxide emissions by 20 per cent. on 1990 levels by 2010. Longer term, the UK aims to strengthen its action further by putting itself on a path to a 60 per cent. reduction in carbon dioxide emissions by 2050.

Mr. Kidney

To ask the Secretary of State for Environment, Food and Rural Affairs what plans she has to(a) survey and (b) monitor the UK's future biodiversity in respect of insects. [165309]

Mr. Bradshaw

An organisation called the National Biodiversity Network Trust is currently co-ordinating actions by a range of interested parties to bring together the biological recording efforts of volunteers and agencies. The work of the NBN Trust is supported by the Government agencies responsible for biodiversity and the Government support this work through the grant-in-aid to these agencies.

In addition, DEFRA has provided financial support for specific surveys such as the Millennium Butterfly Atlas and monitoring work on butterflies on land subject to agri-environment schemes. Species of particular concern are subject to individual specific action under the Biodiversity Action Plan and Government support this process through their conservation agencies in England, Wales and Scotland and the Environment and Heritage Service in Northern Ireland. Volunteers, through their relevant national schemes or societies, carry out much of the survey and monitoring work on priority species.

The vast majority of information on the distribution, status and trends of species comes from the activities of volunteers. These are individuals with a special interest in insects who give freely of their spare time. A key part of the work of the NBN Trust is about supporting these people and encouraging the next generation of biological recorders. Replacing the effort of volunteers with contracted survey would be extremely costly and need continued funding. The Government support the work of the NBN Trust as the primary mechanism to secure the continued supply of information from volunteers through capacity building of support networks at national and local scale.

We believe that the short life spans and diverse needs of insects make some of them good indicators of environmental change. Information on the status and trends in insects, and other plants and animals, would be extremely helpful in both detecting adverse change and identifying sustainable practices. We recognise that some groups of insects do not have the resources necessary to provide a comprehensive baseline of information and more resources are needed. DEFRA is currently exploring options for improving surveillance and monitoring of species, including insects, and will consider future funding in the light of discussions with the conservation agencies and representatives of voluntary conservation organisations.
