Biodiversity Hotspots for Planning
收藏资源简介：
<p> <strong>Dataset last updated: 17th November 2023</strong> </p> <p>This dataset provides indicative areas of biodiversity hotspots in Greater London, identified by research and data analysis using methods derived from the Greater London Authority’s (GLA) “<a href="https://www.london.gov.uk/sites/default/files/biodiversity_and_planning_research_report_0.pdf" target="_blank">Planning for Biodiversity?</a>” report (2016).</p> <p>The dataset has been created by <a href="https://www.gigl.org.uk/" target="_blank">Greenspace Information for Greater London CIC (GiGL)</a>. GiGL mobilises, curates and shares data that underpin our knowledge of London’s natural environment. We provide impartial evidence to enable informed discussion and decision-making in policy and practice. The dataset is based on <a href="https://www.gigl.org.uk/our-data-holdings/" target="_blank">GiGL partnership data</a> which are continuously updated.</p> <p>The underlying data for the dataset may have been subject to changes since the current version was modelled. Subsequent versions will provide updated information from the GiGL database annually. The dataset is a coarse-resolution presentation of high-resolution data. To access data at their original resolution, please contact GiGL or visit <a href="http://www.gigl.org.uk/" target="_blank">www.gigl.org.uk</a> for more information.</p> <p>Research for this dataset has been assisted by London and South East England Local Records Centres (LaSER) and the London Boroughs Biodiversity Forum (LBBF), and is based on advice provided by the Open Data Institute (ODI).</p> <p> <br> </p> <h1>Description</h1> <p>To meet Policy G6 D of <a href="https://www.london.gov.uk/sites/default/files/the_london_plan_2021.pdf" target="_blank">The London Plan (2021)</a>, the capital’s spatial development strategy, <span style="color: rgb(36, 36, 36);">"</span> <em style="color: rgb(36, 36, 36);">Development proposals should manage impacts on biodiversity and aim to secure net biodiversity gain. This should be informed by the best available ecological information and addressed from the start of the development process".</em> </p> <p>The <strong>Biodiversity Hotspots for Planning (BHP)</strong> dataset provides developers, homeowners and LPAs an indication of areas, where data are available, that have potential impacts on biodiversity and are likely to be relevant to local planning decisions by applying biodiversity criteria developed by GiGL, based on the original “Planning for Biodiversity?” research. ‘Hotspot’ areas indicate a detected presence of sensitive biodiversity that could potentially be affected by development. Original records can be accessed from GiGL to assist the decision-making process.</p> <p> <span style="color: red;">N.B. 1: Areas without these biodiversity indicator records may still have undetected biodiversity so should also be considered for biodiversity potential on a case-by-case basis.</span> </p> <p> <span style="color: red;">N.B. 2: The dataset is purely indicative and an ecological data search report must still be commissioned as evidence for planning applications. See </span> <a href="https://www.gigl.org.uk/access-our-data/data-search-for-consultants/" target="_blank" style="color: red;">here</a> <span style="color: red;"> for help on this.</span> </p> <p> <br> </p> <h1>Specification</h1> <p>The GIS file shows London as 100m hexagon tiles. Each tile is scored for the known presence of protected species, sites and habitats impact areas based on the impact buffer size as specified in the criteria table below, giving a cumulative score range of 0 to 3. Tiles are considered a hotspot where impact areas overlap the tile by more than 10%.</p> <p> <img src="https://airdrive-images.s3-eu-west-1.amazonaws.com/london/img/dataset/biodiversity-hotspots-for-planning/2019-10-31T12%3A08%3A28/LDS_GiGL_BHP_CriteriaTable.JPG"> </p> <p>Tiles with a score of 0 indicate that there are currently no known protected species, sites or habitats impact areas present in that area based on the criteria table, which excludes some protected species. Tiles with a score of 3 indicate the presence of impact areas for all three categories. Intermediate scores indicate the presence of impact areas for one or more of the categories without specifying which are present. The scores can be used in a thematic map to colour the tiles and visually indicate areas with greater presence of impact areas. A sample thematic map is provided.</p> <p>The dataset will be updated annually using the latest protected species, sites and habitats data available to GiGL at time of creation.
