Preliminary Ecological Assessment (PEA)Greenleaf Ecology provides advice on the likely ecological constraints to development and assesses their likely significance. This process occurs before any more formal Ecological Impact Assessment or Appropriate Assessment and generally comprises a desktop study, walkover of the site and reporting on the constraints and opportunities of the site.
Ecological Impact Assessment
Ecological Impact Assessment (EcIA) is a process of identifying, quantifying and evaluating potential effects of development- related or other proposed actions on habitats, species and ecosystems (Treweek, 1999). Greenleaf Ecology prepares stand-alone EcIA reports and also ecology chapters for inclusion within Environmental Impact Assessment (EIA). We follow best practice methodology and templates for reporting which provide comprehensive reports to meet legislative requirements. We work closely with the client at all stages of the project to provide full information and to aid the project moving forwards towards planning approval in a timely and efficient manner.
Ecological impacts should always be avoided where possible. Close liaison with our clients at all stages of the project can mean that potential ecological impacts can often be avoided through advice on appropriate project design, for example, not locating a project in a particular area to avoid sensitive ecological features or altering the timing of the works. Many impacts can be avoided or reduced by consideration of alternatives. Where residual effects to ecological features are likely, despite mitigation, Greenleaf Ecology designs appropriate compensation measures, for example, improvements to existing habitats, provision of replacement habitat, provision of badger underpasses or replacement bat roosts.
Monitoring the effectiveness of mitigation and compensation measures is often a requirement of planning conditions. Greenleaf Ecology services include the preparation of Construction Environment Management Plans and site supervision during the construction phase; and monitoring of the success of mitigation, compensation or enhancement measures post-construction.
