Appropriate Assessment of the Chilterns Area of Outstanding Chilterns AONB Management Plan 2008-2013 Screening for Appropriate Assessment - Baseline Report Screening of the Chilterns Area of Outstanding Natural Beauty Management Plan 2008-2013 for Appropriate Assessment – Baseline Report 1. Executive Summary 1.1 The purpose of this report is to determine whether there is a need to carry out a full Appropriate Assessment of the Chilterns AONB Management Plan 2008-13. 1.2 This report considers potential impacts arising from the AONB Management Plan alone and in combination with other plans, and with respect to the European sites’ conservation objectives. The sites in question are all, in this case, Special Areas of Conservation (SACs). 1.3 Production of the AONB Management Plan is a statutory duty of the Conservation Board under the Countryside and Rights of Way Act 2000. The plan outlines the Board’s policies for the management of the AONB and fulfilment of its statutory purposes which are: a. To conserve and enhance the natural beauty of the AONB; and b. to increase the understanding and enjoyment of the special qualities of the AONB. 1.4 The SACs potentially affected by the AONB Management Plan are as follows: • Aston Rowant • Chilterns Beechwoods (a composite of 9 sites) • Hartslock Wood • Burnham Beeches (outside the AONB) • Little Wittenham (outside the AONB) 1.5 All policies and proposals in the AONB Management Plan have been screened and it is considered that there are no significant environmental effects on the SACs within or in close proximity to the AONB. Consequently, a full appropriate assessment of the plan is not required. 1 Chilterns AONB Management Plan 2008-2013 Screening for Appropriate Assessment - Baseline Report 2. Introduction 2.1 The Conservation (Natural Habitats &c.) Regulations 1994 (as amended by The Conservation (Natural Habitats &c.) (Amendment) Regulations 2007) require (Regulation 48) that a competent authority shall make an appropriate assessment of the implications for European sites in view of the sites’ conservation objectives. The purpose of this Baseline Report is to ensure that the Management Plan 2008-13 and its policies have no significant environmental impact on sites of European Interest. 2.2 The Countryside and Rights of Way Act 2000 places a duty on Conservation Boards to produce a plan which outlines their policies for the management of the AONB and how they will carry out their functions in relation to it. Management plans must be reviewed at least every five years. 2.3 The previous management plan for the Chilterns AONB, The Framework for Action 2002 – 2007 has now been reviewed, forming the basis for the draft Management Plan 2008 – 2013. 2.4 The Plan sets out broad aims for the management of the AONB. Policies and actions within the Plan outline how these aims will be achieved by the Board and other parties with an interest in the AONB. In formulating the policies and actions within the Plan the Board seeks to fulfil its two statutory purposes which are: a. to conserve and enhance the natural beauty of the AONB; and b. to increase the understanding and enjoyment of the special qualities of the AONB. 2.5 This screening report is intended to determine whether there is a need to carry out a full appropriate assessment of the Chilterns AONB Management Plan (2008 -2013) and its polices in relation to sites of European Interest. 2.6 The Conservation Board, as the ‘competent authority' has to satisfy itself that, in adopting the plan, there will be no significant effect on European sites. 2.7 The Board has liaised with Natural England at an early stage regarding which sites to consider, conservation objectives and key environmental conditions for the sites concerned. 2.8 The Board recognises that the AONB management plan will be implemented in the context of changing spatial patterns and housing growth, as directed by the Regional Spatial Strategies and Local Development Frameworks. These are themselves subject to Appropriate Assessment. The AONB Management Plan does not propose any growth or development, and its policies promote conservation of the natural environment and sustainable use of it. 2 Chilterns AONB Management Plan 2008-2013 Screening for Appropriate Assessment - Baseline Report 3. Sites under consideration 3.1 Summary 3.1.1 There are 3 SACs within the AONB – Aston Rowant, Hartslock Wood and Chilterns Beechwoods. Chilterns Beechwoods comprises of 9 separate sites, of which 8 are within the AONB. 3.1.3 In addition, Burnham Beeches SAC and Little Wittenham SAC have been considered as they are within 10 - 12 km of the AONB boundary and could theoretically be affected indirectly by the Management Plan.

  • Site Improvement Plan Chilterns Beechwoods
    Improvement Programme for England's Natura 2000 Sites (IPENS) Planning for the Future Site Improvement Plan Chilterns Beechwoods Site Improvement Plans (SIPs) have been developed for each Natura 2000 site in England as part of the Improvement Programme for England's Natura 2000 sites (IPENS). Natura 2000 sites is the combined term for sites designated as Special Areas of Conservation (SAC) and Special Protected Areas (SPA). This work has been financially supported by LIFE, a financial instrument of the European Community. The plan provides a high level overview of the issues (both current and predicted) affecting the condition of the Natura 2000 features on the site(s) and outlines the priority measures required to improve the condition of the features. It does not cover issues where remedial actions are already in place or ongoing management activities which are required for maintenance. The SIP consists of three parts: a Summary table, which sets out the priority Issues and Measures; a detailed Actions table, which sets out who needs to do what, when and how much it is estimated to cost; and a set of tables containing contextual information and links. Once this current programme ends, it is anticipated that Natural England and others, working with landowners and managers, will all play a role in delivering the priority measures to improve the condition of the features on these sites. The SIPs are based on Natural England's current evidence and knowledge. The SIPs are not legal documents, they are live documents that will be updated to reflect changes in our evidence/knowledge and as actions get underway.
