 "Natural Diversity and Human Needs in England's Urban Areas."

Until the beginning of the last century, when the London squares and the first Victorian town parks were set up, the towns and cities of England contained little generally accessible planned natural open space. The garden villages and cities carried the concept further.

Continued expansion of urban areas in the early 1900s gave rise to public concern. This found political expression in the Planning Acts which aimed to control development in order to protect rural areas. In 1949, the National Parks and Access to the Countryside Act set up the Nature Conservancy. Its job was, amongst other things, to identify sites of particular importance to nature conservation and notify the planning authorities so that they could protect them using the Planning Acts.

By the early 1960s, a strong link had grown up between nature conservation and planning, based on the premise that development threatened wildlife and natural features, and that site protection was the way to deflect threats. There was no real conviction that ecological science could inform and help design development, or that development could be used positively to promote nature conservation.

During the 1960s, the first systematic inventories of rural environmental and habitat-types were started. The urban areas were largely ignored until, in 1974, eight Metropolitan County Councils (now abolished) were established in England. In order to advise them properly, habitat-type and site inventories were needed here too.

Publication in 1978 of a report, 'The Endless Village' (Teagle, 1978), derived from the first of the inventories, generated a great deal of public interest and can be said to be the catalyst for the Urban Wildlife Partnerships movement which has developed through the 1980s and 1990s.

"A Review of Management Options for the Control of Brachypodium pinnatum in Calcareous Grasslands in England."

The coarse grass Brachypodium pinnatum is a significant problem in many calcareous grassland sites in England. Its spread reduces species diversity and it is difficult to control. This paper reviews the experience of site managers in England using a range of techniques including grazing (Sheep, cattle, ponies), mowing, burning, herbicide treatment and others. Each of these is found to have both positive and negative effects, and their effectiveness depends upon how they are used and the precise management objectives.

"Studies of Plant Ecology in Sinai, Egypt: An Eco-floristic Study in Saint Catherine Province, South Sinai."

Ecological and floristic investigations were carded out between altitudes of 500 and 2641 m in the mountainous area of Saint Catherine, Southern Sinai, down to Feiran Oasis from 1988 to 1994. The climatic and bioclimatic relationships are discussed and the pluviometric quotient is calculated, with the ombrotherinic diagram for Saint Catherine Province presented here for the first time. Case studies of the ecological degradation due to human interference are described. The distribution pattern of rare, endangered and endemic species and also dominant species of vegetation types are considered. This study relates to the scope of proposed conservation programmes for wildlife in the area. A list of 277 species of Flteridophyta and Spermatophyta belonging to 57 families is given, recorded and collected from the mountainous region in Southern Sinai (the complete list is available on application to the authors). Amongst these are 17 endemic species present in the study area. Valid names, ecological notes and new distributional records are given for all species. Twelve species are recorded here as new to Sinai or Southern Sinai.

"Rhododendron ponticum in Native and Exotic Environments, with Particular Reference to Turkey and the British Isles."

The status of Rhododendron ponticum L. in both native and exotic situations is noted with reference to studies in Turkey and in the British Isles, and current knowledge is reviewed. Its history of anthropogenic introduction and the conservation implications of subsequent spread in the British Isles are considered. Key aspects of Rhododendron ecology are discussed with respect to its invasive behaviour in particular situations, and to the plant's potential impact on associated fauna and flora.

The invasive behaviour of R. ponticum as a problematic and serious weed in forestry is related to management in both native and exotic environments. Changes in management practice could minimise these problems.

Previously overlooked, the importance of ancient Rhododendron forest in lbrkey is discussed along with the imminent threat to the few remaining sites.

The implications of incomplete and sometimes ill-formed transfer of information from the UK to forest managers in Turkey are highlighted, together with the chronic lack of available information from R. ponticum's other native locations. The latter include Spain, Portugal, Gibraltar, Bulgaria and Georgia.

"A Comparison of the Soil Characteristics of Lowland Heathland which has been Rotovated and Turf Stripped."

An unreplicated trial was set up in 1990 to compare the effectiveness of three methods (rotation, forage harvesting and turf stripping) in the restoring an area of lowland heathland dominated by wavy hair grass Deschampsia flexuosa to heather dominance. Forage harvesting did not appear to be an effective method of heathland restoration and so was not considered further. Subsequently in 1995 a comparison was made of the soil characteristics of the rotovation and turf stripping treatments and an untreated control. Although the experiment is not suitable for the application of rigorous statistical methods, a number of trends are suggested by the results. Whilst there were no clear effects of treatment on extractable phosphorus levels, turf stripping led to greater reductions in total and available nitrogen than rotovation at the 0 em soil depth (the soil surface). Nevertheless, rotovation led to a reduction in total nitrogen and available NH4-N at the 0 m soil depth. This has important implications for heathland restoration in situations where formerly heather-dominated heathland has been replaced by acidic grassland because rotovation is much cheaper than turf stripping since it doesn't require the removal or transportation of soil.

"The Sustainability of Nature Conservation in the Saxony-Ashalt State of Germany, with Special Reference to Problems of Water and Wetland Ecology."

The State of Saxony-Anhalt is one of the five new federal states in Germany, which formerly belonged to the German Democratic Republik (GDR), until the German reunification in 1990.

In terms of population and industrial structure, there are strong differences between the north and the south of Saxony-Anhalt. While the northern part is thinly populated and has less industry, the southern part has a higher population and a concentration of industry. With its varying industrial structure and population the State includes areas with extremely high air, groundwater and surface water pollution. There are also many uncontrolled dumpsites and contaminated areas inherited from the past. In addition to these environmental burdens, Saxony-Anhalt is also facing problems such as the contamination of soil by heavy metals and dioxins, the storage of hazardous materials and radioactive waste, contaminated spoil banks and the restoration of spoil left from open-cast coal mining. These examples show the broad spectrum of environmental pollution experienced in the region.

However in 1990, the year of German reunification, a shutdown of many production units and a reduction of industrial output began. East German industry was not competitive with the industry in western Germany and in the European Community generally. As a result, the "traditional" environmental problems are decreasing due to the reduction of production and pollutant output. Additionally, environmental policy encouraged the introduction of purification techniques, and the conversion of production to clean technologies.

On the one hand, traditional problems are beginning to lose their importance to a significant degree. Meanwhile, other problems, which are typical of Western Europe, are steadily increasing.

The main difference emerging is that the environmental problems in the former GDR were primarily problems of quality of exploitation and use of natural resources, the problems now are of quantity. The needs of nature conservation and soil protection are becoming acute. The accelerated rate soil capping and the despoilation of the countryside are key issues. In the old federal states, 12 % of the total land area was effectively capped or sealed for settlement, traffic and industry. In the new federal states this is actually lower at 9.9 %, but everyday there is an additional consumption of nearly 90 ha (Thomas, 1995).

"Off-road Motorcyclists - A Survey of the Urban Fringe."

A questionnaire was issued to off-road motorcyclists unofficially using a derelict brickworks on the Greater Manchester/Cheshire boundary. The majority of respondents were local, aged under 21, and used specialist off-road bikes that were transported to the site. Most were regular users coming mainly at weekends. Although only a minority were members of recognised motorcycle clubs, 80% of respondents expressed an interest in helping to manage the site on a more formal basis. The formation of a core of regular users at a site where the sport was tolerated may have helped develop more responsible attitudes than are sometimes credited to off-road motorcyclists. However, the loss of the site in 1992 was followed by a marked increase in problems caused by illegal motorcycling elsewhere in the area.

The Grazing Index for Heather Moorland

English Nature has produced an important guide to help integrate farming and nature conservation.

England's high heather moorland supports many distinctive plants and animals. Ale variety and numbers of these species and the condition of the vegetation, is greatly influenced by the numbers of sheep, cattle and ponies which graze them. Centuries of management have helped create our moorlands, but overgrazing particularly since the 1950's has had a drastic impact. Plants may become stunted or contorted, or uprooted or grazed out completely, leaving only the plants that can withstand the high grazing level. With fewer types of plant, mainly course grasses, the variety of wildlife on the morrs is seriously affected. Until now, ecologists have used a variety of methods to monitor both upland plants and grazing, but the results have not been easy to compare.

A free leaflet, The Grazing Index for heather moorland, is available from English Nature local regional offices, or direct from Claire McDonald, Uplands and Freshwater Team, English Nature, Northminster House, Peterborough PEI lUA. (Field notes, describing how to carry out the Grazing Index assessment, are also available on request).

Accurate Comparisons
English Nature has developed the 'Grazing Index', a new, uniform method of surveying heather moorland. This allows land managers to carry out quick and easy assessments of how well or badly grazing levels are maintaining the variety of moorland plants. The results allow accurate comparisons over time and between sites. 71e Index involves dividing the land into 50ha blocks and then carrying out a three-stage check. The results are then measured against a scale to give a read-off of the condition of the vegetation for each block. According to Jayne Manley, the English Nature Ecologist responsible for the Index: "Using the Grazing index, a 50ha block can be checked in under two hours, and one major advantage is that the people doing the survey don't need a huge botanical knowledge. A free leaflet, 'The Grazing Index for Heather Moorlands', is available from English Nature local/regionbal Offices or direct from Claire MacDonald, Uplands and Freshwater Team, English Nauture, Northminster House, Peterborough, PE1 1UA ( Field notes, describing how to carry out the Grazing Index assessment, are also available upon request).

Understanding poeple's perceptions of urban fringe woodlands

Growing in Confidence

Jacqui Burgess for the Countryside Commission

Sensationalised reports in the of crime in local woods are putting people off visiting woodlands. Fear for personal safety is a serious issue. Millions of people enjoy their leisure time outdoors. This is often in public open space aincluding woodlands. However, fear of crime, especially of physical violence in open spaces is increasing and has a detrimental effect on the quality of life, particularly for more vulnerable social groups. Women, children and members of ethnic minority communities are most affected. This fear is a powerful emotional response to a sense of threat. Anxiety and fear are produced by both informal discussions between people, and reactions to media coverage of the issues. Research for the Countryside Commission's Community Forest Unit highlighted the extent to which fear of crime may have spread from urban areas into peoples experiences and perceptions of the wider countryside, especially urban fringe woodlands. Some are deterred from using woods and forests for recreation, because they are anxious about personal safety. As one woman in the study said: "It's not worth taking the risk for the sake of a walk."

Why are landscapes which give people so much pleasure (with considerable evidence for woods and forests being amongst the most highly valued sites for their beauty and naturlaness) should also be viewed as so unsafe? The extent to which people's vision of an "unsafe" urban setting is projected onto woodlands is important. Relationships between people and their daily environment are subtle, with no simple determinism operating. They are also largely taken for granted. Women and children need the comforting presence of other people who may, firstly, deter an attacker and secondly, come to someone's assistance if needed. The research shows that the physical qualities of woods (being enclosed by trees, and of not being able to see very far) are misinterpreted as if they were like physical features in the city and, potentially dangerous. This problem wll worsen as generations of children are denied the chance to play in the woods as their parents and grandparents did. An important factor in people's sense of anxiety in woodlands, is communication. The modem gnews' stories circulate in highly sensational reports of very rare, extremely violent crimes against (usually) women and children in public spaces, parks and natural settings. There is always a risk that a stranger in a public space might do someone harm. However, the probabilities of this are actually very low, especially compared with the total number encounters in daily social interaction.

These rare events are given highly sensationalised treatment by much of the media, ever looking for a shocking story of extreme violence. Of further concern is that the coverage of such events has expanded dramatically over trecent years.

People are bombarded by news of an event or incident. If there is an inquest (some months later) there will be similar coverage. The victims are usually women, children and often members of ethnic minority communities. The message presented, received and reinforced, is that parks, woods and other green spaces are unsafe.

The people involved in the research on the woodland project, deeply resented the emotional impact from coverage of violent crime in the media. They particularly wanted to challenge the media message of public spaces being dangerous for women and children. Furthermore, they looked to agencies such as the Countryside Commission, to provide the mechanisms and opportunities to renew people's confidence in using their woods.

From this work, prorgrammes in confidence building are being developed for Community Forests. These will include design improvements; manamagement strategies which recognise and address people's anxieties and programmes to help women and children from different communities to enjoy woodland an small social groups. The ersearcgh produced many ideas and suggestions highlighting the extent to which people wish to enjoy the simple (and usually free) pleasures of a walk in the woods. This is an important report - READ IT!

The report on Jaqie Burguess' research, called 'Growing in Confidence', is available from the Countryside Commission, Cheltenham.



Planning Policy Guidance 9 - Nature

The Department of the Environment (as was) has issued new guidance on planning and nature conservation for England, as one of a series of Guidance Notes addressing planning issues. The 59 page A4 document has much information.and is a useful and important document and a surprisingly easy read. 'Mis is a key report, and should be read carefully by all nature conservationists in England. For example, for those interested in issues which affect planning for nature conservation in urban areas, it states: "The conservation of nature is important. Attractive environments, where attention is given to nature conservation, are essential to social and economic well-being". In places it emphasises the need to protect wildlife sites. but it is insisitent that only sites of clear local, national or international importance are given strong protection. Planning should take the local, national or international status into account and unnecessary constraints on development should be avoided. "Nature conservation can be a significant material consideration in determining many planning applications ........ However, permission should not be refused if conditions can be imposed to prevent damage (para. 27). The report emphasizes that planning authorities should use conditions to safeguard nature conservation where damage is a risk (para. 28). This is sensible guidance, but will be fraught with difficulties uless local authorities have the expertise and resources to impliment such conditions. Important for many wildlife and geological sites, the guidance suggests that the value of urban sites not not recognised by formal nature conservation designations, should also be taken into account. This applies to features which "...are of major importance for wild flora and fauna ........ and includes: ...... those which, because of their linear or continuous structure or their function as stepping stones, are essential for migration, dispersal and genetic exchange". Examples are rivers with their banks, traditional field boundary systems, ponds and small woods. This argument is expanded in para. 15. which says "Statutory and non-statutory sites, together with countryside features which provide wildlife corridors, links or stepping stones from one habitat to another, all help to from a network necessary to ensure the maintenance of the current range and diversity of our flora, fauna, geological and landforin features and the survival of important species". Nature conservation sites in urban areas have particular value for local people, and those are recognised in the Guidance Note. "These sites are important to local communities, often affording people the only opportunity of direct contact with nature ...... (para. 15). PPG9 emphasises that nature conservation objectives are important in planning for urban areas (para. 19) and that these issues are best dealt with on a strategic basis (para. 21). The potential for enhancement of areas for wildlife is noted in para. 15 Sensitive landscaping and planting, the creation, maintenance and management of landscape features important to wildlife, and the skilled adaptation of derelict areas can provide extended habitats". This is a welcome emphasis on the positive role of developers, along with the responsibility to assess the impact of development proposals and show minimal adverse impact. The sometimes enormous and often neglected potential for environmental enhancement is recognised but the development industry and the planning authorities, have a long way to go in bringing this to fruition. It is essential that planners and developers get the best possible advice. The role of English Nature and the non-govemmental organisations in this is noted in para. 20. The potential roles of local authority ecological advisory services however, should not be overlooked, and they ned resources and recognition! This is an important document. It is essential reading for everyone involved in nature conservation and planning issues and costs £8.50 from HMSO.
