INTRODUCTION The aim of this document is to provide a systematic basis for the identification of non-statutory or ‘Local’ wildlife sites in Cornwall; these sites are called County Wildlife Sites. County Wildlife Sites: provide a comprehensive suite of sites that complements other site networks; provide wildlife refuges for most of the UK’s fauna and flora; have a significant role to play in meeting overall national biodiversity targets; represent local character and distinctiveness; contribute to the quality of life and the well-being of the community, with many sites providing opportunities for research and education; are an established feature of the statutory planning process in Cornwall; are shown in County Minerals, Waste and Local Development Frameworks, and are an important factor taken into account when planning decisions are made. For these reasons it is important that the process of site selection is transparent and that the rationale behind decisions made is recorded and made available to interested parties. This document is therefore of relevance to planners, landowners, developers and those working in wildlife conservation. We hope to update this document regularly and expect practical use of these criteria will highlight any amendments and updates required. We view this document to be iterative and welcome all feedback. An equivalent document (County Geology Site Criteria for Cornwall) has been produced to provide a similar basis for the identification of County Geology Sites. These two documents provide criteria to ensure a comprehensive local sites system is in place for Cornwall. The documents are produced in line with guidance given by the Government’s Department for the Environment Food and Rural Affairs (DEFRA) in its publication “Local Sites: Guidance on their identification, selection and management” (DEFRA, 2006), which aims to promote more transparent and consistent approaches to the development and operation of systems to identify sites of local importance for nature conservation in England.

    Report Number 623 A literature review of urban effects on lowland heaths and their wildlife English Nature Research Reports working today for nature tomorrow English Nature Research Reports Number 623 A literature review of urban effects on lowland heaths and their wildlife J C Underhill-Day RSPB, Syldata Arne, Wareham Dorset BH20 5BJ Telephone: 01929 550969 email: [email protected] You may reproduce as many additional copies of this report as you like, provided such copies stipulate that copyright remains with English Nature, Northminster House, Peterborough PE1 1UA ISSN 0967-876X © Copyright English Nature 2005 Executive summary Introduction Heather clad lowland heath developed on light, freely draining, acid soils following prehistoric woodland clearance, and down the centuries, has been kept open by grazing, burning and cutting. As the economic value of these uses declined, considerable areas of heath were lost to agriculture, forestry, housing, roads, mineral working and other uses, and today, much of what is left is adjacent to built up areas, especially in Dorset. These lowland heathland fragments can be found across much of southern England on suitable soils. Much of the research on heathlands over the last twenty years has concentrated on the Dorset heaths, which are now almost all SSSIs and mostly within the Dorset Heathland SPA. While this report reflects the bias in the literature towards work in Dorset, the results have wide applicability to urban heathlands that are accessed by the surrounding urban populations for amenity and recreation whether in Dorset or elsewhere. This urban public access places considerable pressures on the heaths, for example through disturbance, wild fires, trampling, predation by domestic pets, pollution and enrichment.

  • Churchtown Farm Community Nature Reserve Education Pack Introduction
    Churchtown Farm Community Nature Reserve Education Pack Introduction... Welcome to the Churchtown Farm Community Nature Reserve education pack! This pack has been compiled to act as a resource for teachers and group leaders to facilitate the use of this fantastic nature reserve for educational purposes. We hope that by using this pack the full potential of the nature reserve as an outdoor classroom, and a place to enjoy nature, can be realised! Churchtown Farm Community Nature Reserve... The Cornwall Wildlife Trust’s Churchtown Farm Community Nature Reserve is an important place both for people and wildlife. The Reserve has a wide variety of different wildlife habitats, mostly hay meadows with arable fields, woodland, wetland, scrub, rocky shoreline, mudflats and an extensive network of hedgerows. There is a rich history of quarrying, farming and nautical activities and the site’s two quarries and the headland running around the west and south shores of the reserve are County Geological Sites. From the reserve there are extensive views over the River Lynher, the River Tamar and beyond to Devonport and Plymouth. Its location on the edge of Saltash makes it an ideal place for people to escape for a bit of peace and quiet. The 60 hectare (150 acre) site falls within the Tamar Valley Area of Outstanding Natural Beauty, and the estuary foreshore lies alongside the Tamar Estuary candidate Special Area of Conservation (cSAC), a designation of international significance. As a nature reserve with this kind of protection, this site will be safeguarded for its resident wildlife and its visiting public! Putting the Community in Nature Reserve..

  • Common Standards Monitoring Guidance for Lowland Heathland
    Common Standards Monitoring Guidance for Lowland Heathland Version February 2009 Updated from (February 2004) ISSN 1743-8160 (online) CSM Guidance for Lowland heathland Issue date: February 2009 Common Standards Monitoring Guidance for Lowland heathland 1 Introduction 1.1 Lowland heathland in England, Wales and Northern Ireland comprises a range of habitats characterised by the abundance of ericoids or gorse species. It occurs on generally nutrient-poor soils, usually below 300 m. Heathland in Scotland is rarely defined as lowland heathland; most Scottish heathland occurs above the upper limits of agricultural enclosure. However, some forms of heathland at low altitudes, similar in character to those in England, Wales and Northern Ireland and usually within the enclosed part of the landscape, do occur in Scotland, although mostly as small fragments. The most distinctive and extensive are the coastal heaths. 1.2 Lowland heathland includes dry, wet, humid, chalk/limestone, coastal and lichen heaths, and all successional stages from bare ground to shrubs. See Annex 1 for a full definition for CSM purposes of lowland heathlands in terms of components, Phase 1 habitat survey classes, NVC types and Annex I (Habitats Directive) equivalents, and section 2 below for more detailed descriptions. 1.3 Guidance on monitoring is summarised in table 1 (lowland dry heath) and table 2 (lowland wet heath). Upland heathland is covered by separate guidance, but the distinction between upland and lowland examples may sometimes be difficult. Heath vegetation on maritime cliff/slopes and dune heath are both included within the lowland heathland guidance but assessment of these types should be done in conjunction with the relevant coastal guidance section.

  • Lowland Heathland and Lowland Dry Acid Grassland in Oxfordshire
    LOWLAND HEATHLAND AND LOWLAND DRY ACID GRASSLAND IN OXFORDSHIRE UK Biodiversity Group - Priority Species associated with heathland 1. INTRODUCTION Nightjar Lowland heathland is characterised by the presence of species Linnet such as heather, bell heather, and gorse, and it is associated with Dingy mocha moth acidic, nutrient-poor soils. Acid grassland also occurs on Grey scalloped bar moth, nutrient-poor soils and is characterised by species such as common bent, sheep’s sorrel, heath bedstraw and tormentil. Parched acid grassland, which becomes excessively dry in Other Associated Species summer, may support a number of uncommon, ephemeral Tree pipit species, such as small cudweed. Stonechat Emperor moth Heathland and acid grassland are formed when forests on nutrient poor soils are cleared for agriculture. It requires White-line snout moth management to check scrub invasion and the subsequent Small red damselfly development of woodland, and to keep the nutrient content of Adder the soil low. In the past this management took the form of grazing, burning and gathering of heather and gorse, for such Blue fescue uses as fuel and thatch. Heathland is not only an important Heath cudweed habitat for wildlife but also forms a valuable part of the cultural Heather heritage of the U.K. Bell heather In Oxfordshire, heathland and acid grassland were never very Sphagnum mosses common and are now very rare habitats largely restricted to the sandy soils on the Corallian sandstone (where it forms a grassy Associated Habitats ‘Breckland’ type heath) and the clay-with-flints and pebbly Woodlands soils of the Chilterns plateau (where heather forms a mosaic with acid grassland).

In Norfolk, heathland is April 2004 Version 2 much more of a mosaic, with acid grassland and 17 November 2011 Version 3 bracken often being significant elements. Even more distinctive are the heaths of the Brecks which include chalk grassland and little or no heather. In East Anglia, the typical lowland acid grassland community is NVC U1, comprising sheep’s-fescue Festuca ovina, common bent Agrostis capillaris and sheep’s sorrel Rumex acetosella. Other species may include wavy hair-grass Deschampsia flexuosa, heath bedstraw Galium saxatile and tormentil Potentilla erecta. 1., CURRENT STATUS National Status In England, only a sixth of the heathland present in 1800 now remains. The UK has about 95,000 ha of lowland heathland (58,000 ha of which are in England) representing about 20% of the international total of this habitat. As with other lowland semi-natural grassland types, acid grassland underwent substantial declines in the 20th century. Although there are no figures available on the current rate of loss, it is thought to be slowing. The decline is primarily the result of under-management, specifically under-grazing and abandonment.
