Ecological Impact Assessments


The Town and Country Planning (Environmental Impact Assessment) Regulations 2011 set out the types and sizes of development that require a full Environmental Impact Assessment (EIA), which are generally larger infrastructure projects or those associated with industries with the potential to cause significant pollution. Schemes such as house building, industrial estates and caravan sites can also require an EIA if they exceed a size threshold and they are considered likely to have a significant environmental impact.

Biodiversity or ecology usually forms one of the main strands of an EIA and EECOS can provide Biodiversity or Ecology chapters to the following as a contribution to satisfying the regulations:

  • EIA Screening report – a document that considers the potential impacts of the scheme and the species and habitats that may be affected in order to allow the relevant planning authority to determine whether or not a full EIA is required on ecological grounds;
  • EIA Scoping report – a document that identifies to the relevant planning authority the species and habitats that need to be considered, once it has been established that an EIA is necessary, in order that the contents of the biodiversity chapter of an EIA can be agreed;
  • Environmental Statement – a detailed report that: i) describes the site, the scheme, and the construction and operational impacts that may arise; ii) identifies the ecological receptors that may be affected by the scheme; iii) assesses which species and habitats will be affected by the scheme and determines the significance of those impacts; iv) sets out the measures that will be used to avoid, reduce or offset those impacts.

In order to complete this work EECOS ecologists would normally carry out a survey following the Preliminary Ecological Appraisal methodology, followed by any species specific surveys that are relevant to the site and the scheme. These will provide the information needed to prepare each of these documents, with reference to the Institute of Ecology and Environmental Management’s best practice guidelines (

EECOS works closely with clients to flag up any specific ecological issues at an early stage so that impacts can be avoided or adequately mitigated without causing delays. Planning for species surveys and to allow for any licence applications is essential in the smooth running of these schemes.
