Landscape, Biodiversity and Trees Supplementary Planning Document December 2018 Foreword Basingstoke and Deane has a range of high quality natural environment assets that are greatly valued by residents and visitors alike. The Basingstoke and Deane Local Plan 2011- 2029 sets out ambitious plans for growth, and it is important that any impacts on the natural environment are sensitively and appropriately considered to ensure that our valued green spaces, landscapes and habitats continue to contribute to the borough’s environment. This Supplementary Planning Document adds further detail to the natural environment policies in the Local Plan, providing guidance on how existing green infrastructure, landscape, biodiversity, and trees should shape development proposals and be considered as part of the planning process. The document will help to both protect and enhance the borough’s landscapes, minimise impacts on and provide net gains for biodiversity, and ensure that the many environmental benefits of trees are recognised. As such, it will help to create distinctive, high quality and healthy places to live. This document has been informed by extensive consultation including a seven week formal consultation with residents and stakeholder. It has been prepared in accordance with the Town and Country Planning (Local Planning) (England) Regulations 2012 and is a material consideration in the determination of planning applications.
