Geographic Information Systems (GIS) 

enims Ltd offers a range of high-quality mapping services that complement our ecology and landscape management services. These services are provided using Quantum Geographical Information Systems (QGIS) to carry out spatial analysis of ecological data.  These maps can be provided as a stand-alone product or to be included within our reports. An enims Ltd mapping template is used to produce clear, consistent and well-presented maps.

At enims Ltd we can provide the following GIS mapping services;

  • Phase 1 habitat maps

  • National Vegetation Classification maps

  • Ecological Constraints and Opportunities Plan

  • Survey Result maps

  • Desk-based study and waterbody location maps

Phase 1 Habitat Maps

The CIEEM Preliminary Ecological Appraisal and Ecological Impact Assessment guidelines state that a recognised mapping system such as Phase 1 habitat map should be used to display all habitats listed on-site. These maps are displayed using the official JNCC guidelines called the ‘Handbook for

Phase 1 habitat surveys’.

enims has a team of GIS experts that can produce a high-quality Phase 1 habitat maps showing habitats using the correct colour codes and target notes with further information on ecological constraints or species to carry out data analysis. A Phase 1 habitat map is used for Ecological Appraisals, Biodiversity Impact Assessment and Habitat Regulations Assessments to display clear information on the quantity of habitats and allow these assessments to be carried out.


National Vegetation Classification Maps

We offer a high-quality mapping system called National Vegetation Classification. These maps show the types of vegetation communities within a habitat and allows spatial analysis to be carried out. These maps are produced at a consistent standard and displayed using the enims template. An NVC map is used for vegetation survey reports and provides clear information for the local planning authority on the condition of valuable habitats or mitigation required.

Ecological Constraints and Opportunities Plan (ECOP)

An Ecological Constraints and Opportunities Plan is a useful drawing that shows ecological constraints or features for other professionals. This mapping methodology is required for Ecological Assessments as stated by the BS 42020:2013 Biodiversity - Code of Practice for planning and development. This type of plan shows the location of biodiversity constraints and opportunities to help inform the pre-application design, decision making and implementation stage such as biodiversity management plans.

The plan can be cross-referenced to CAD drawings or landscape plans of the site to aid with the decision-making process for mitigation and enhancement measures to a development. This ECOP is important to show where ecological features require protection and where biosecurity measures are necessary to manage the risk of spreading pathogens or non-native species. This tool will be essential for you to make design decisions and understand why further surveys or mitigation is required.

Survey Results Maps

enims Ltd provides a range of survey maps showing; bat, bird, badger, reptile, great crested newt, hazel dormice, otter and water vole survey results. These maps present accurate data from Ordnance Survey grid references and handheld Geographical Positioning System (GPS). Therefore, all survey maps record information at a high standard of accuracy and quality. A survey map is important to advise mitigation strategies and licence method statements.


Desk-based Study Maps

As part of a Preliminary Ecological Appraisal or Ecological Impact Assessment there is a requirement for a desk study to carry out spatial analysis of; Ordnance survey maps, local record centre species records and designated sites data. Our team produces maps that display protected or notable species with buffer maps outlining the distance the records are from site and any potential for these species to be present within the site. These maps use aerial imagery and ordnance survey maps to identify presence of priority habitats or waterbodies within the local area. This information is essential to understand habitat connectivity to a site for protected species and this information advises appropriate biodiversity enhancement measures that link the landscape together.

All desk study maps are produced to allow you to understand the ecological value of your site within the wider landscape and ensure a Preliminary Ecological Appraisal achieves the standards required to support planning permission.
