This week Defra released the highly anticipated Natural Environment White Paper titled ‘The Natural Choice: Securing the Value of Nature’, outlining Government’s vision for the future of landscapes and ecosystem services. The paper emphasises that although we know the environment provides many irreplaceable and valuable services we have been unsustainably exploiting natural capital for many years, leading to biodiversity loss and degradation. Plans for action to halt and reverse the decline in biodiversity and ecosystem services are described.

In a Defra press release following the launch of the White Paper Environment Secretary Caroline Spelman said “The true value of nature should be built in to the decisions we make – as individuals, organisations, businesses and governments – so that we become the first generation to leave the environment in a better condition than we found it.”

One of the key plans is to create 12 new Nature Improvement Areas (NIAs), designed to fulfil many of the goals of Lawton’s ‘Ecological Restoration Zones’, and help wildlife adapt to climate change. A competition will be set up to determine the site of the 12 initial Nature Improvement Areas, and Local Nature Partnerships (LNPs) will be invited to enter their area. So far £7.5 million has been pledged to fund these Nature Improvement Areas. However the Lawton Review ‘Making Space For Nature’ estimated the cost of restoring damage already done to the natural environment at around £0.6 to £1.1 billion.

The Government also plan to use the imminent reforms of the planning system to achieve environmental objectives, and improve ecological networks. Planners will be encouraged to put the natural environment at the heart of all decision making. Reforms to the planning system will include introducing voluntary use of biodiversity offsets in some areas, with a view to broadening these pilot schemes over time.

Another key element of the paper is plans to reconnect local people, particularly children, with nature, by creating a new Local Green Area designation to protect green spaces of particular importance to communities, and removing barriers preventing teaching outdoors. Communities will be supported to volunteer to protect their local wildlife areas.

A new independent committee (The Natural Capital Committee) will be established to advise the Government on the state of natural capital in the UK. Following the release of the UK National Ecosystem Assessment natural capital will be included in the UK Environmental Accounts.

Businesses will be expected to take greater action to protect the environment, and the Government have proposed to investigate potential ways to expand markets in which ecosystem service providers are paid by the users of the service.

The government have also pledged to influence policy in the EU and internationally by showing leadership and ensuring that there are ambitious environmental commitments included in the reformed Common Agricultural Policy and Common Fisheries Policy. £25 million will be donated to the Darwin initiatives fund to help ecosystem and development projects, reducing poverty worldwide. Initiatives to reduce climate change will also continue to be supported through £2.9 billion of funds which will distributed to projects such as Reducing Emissions from Deforestation and Degradation.

In general the White Paper received a positive response from conservation organisations. The director of conservation at the RSPB Martin Harper said “Nature Improvement Areas are about looking at conservation on a joined up, landscape scale, instead of a series of patchwork measures dotted across our landscape. It’s fantastic to see the Government promoting this idea.” At the Wildlife Trusts Paul Wilkinson, Head of Living Landscapes said “How this White Paper is implemented and adopted by all Government departments will be critical. There is a vital need to ensure it influences the current policy reforms around planning, development and growth.” All emphasised that they would be willing to work with the government to ensure that the ambitious plans are carried out.

A written parliamentary question tabled by Bob Russell MP to DCLG today received an answer from the Parliamentary Under Secretary of State for Natural Environment and Fisheries in DEFRA, Richard Benyon MP.

Question: “To ask the Secretary of State for Communities and Local Government with reference to page 17 of The Coalition: Our Programme for Government, what plans he has to promote green spaces and wildlife corridors in order to halt the loss of habitat and restore biodiversity.” [348]

Answer: (Richard Benyon) “I have been asked to reply. We look forward to receiving Sir John Lawton’s report, “Making Space for Nature”, later in the summer. Sir John’s update in March reported that to achieve a coherent and resilient ecological network we will need to look beyond existing designated sites and take account of landscape designations, local wildlife sites and green spaces.

The Government are also looking forward to the completion of work currently being carried out by Natural England on the implementation of landscape-scale enhancements to benefit wildlife. This will build on and use the lessons learned from existing work such as the Great Fen, a collaboration between Natural England, Environment Agency, the local Wildlife Trust and district council, which is joining up two national nature reserves through creating 3,700 ha of wetland habitat in Cambridgeshire, which will deliver benefits not only for biodiversity but also for water quality, recreation and local communities.

In addition, this Government will deliver a White Paper, the first since 1990, that will, finally, take an integrated approach to the natural environment in all its aspects. By reflecting nature’s real value in our social and economic decisions we will be able to review and improve the ways in which we both harness and protect it. We are currently considering options and time scales for taking this commitment forward.”

This reaffirms DEFRA’s commitment to publishing a White Paper on the natural environment, as suggested by the Prime Minister before reaching government.

Speaking at the tenth annual Darwin Initiative lecture last night (see post below for further details), Hilary Benn announced that Professor Sir John Lawton, ex-President of the BES, has been appointed to chair the review of England’s wildlife network.

The review will explore if England’s collection of wildlife areas represents a coherent and robust ecological network that will be capable of responding to future pressures such as climate change. Commenting on his appointment, Professor Lawton said that “Climate change poses a major challenge for England’s wildlife, but it is by no means the only threat. We need to ensure that the existing protected-area network is fit for purpose, and if it isn’t, what we do about it.” The review will publish its findings in June 2010.

New research published in Biological Conservation suggests that strips of land alongside motorways play an important role in maintaining plant and spider diversity within intensive agricultural landscapes.

The research was conducted along one 50km stretch of Motorway near Paris, collecting data from 25 individual sites. Where possible, sites with hedgerows were selected within 1.5km from sites without hedgerows.

The researchers found that hedgerows were positively associated with plant diversity – being twice as rich as the grass verges (without hedgerows). Spider diversity was closely associated with proximity to natural woodland, with little significant difference in diversity between hedgerows and grassland. Spider community structure differed between habitat types; hunting and ballooning spiders were found more often in open grassland, whereas web-building and ‘non-ballooning’ spiders were most common in hedges.

Future research may benefit from looking at strips on different motorways in comparable landscapes rather than replicating along the same stretch of motorway. However, this preliminary research is important in that it has shown that the means in which motorway verges are planted and managed can increase plant and insect diversity in different ways.

After construction of future motorways, some restoration can be achieved by creating a mosaic of hedges and grassland, providing spatial and temporal refugia for biodiversity as well as increased ecological connectivity.
