Ecological Impact Assessment (EcIA) is the process in which the effects of a proposed action (i.e. residential development) on Important Ecological Features (IEF) (i.e. important habitats, species and ecosystems) are identified, quantified and evaluated. Residual significant effects of the project are assessed after the mitigation hierarchy has been applied.
EcIA can be used for smaller scale project assessments or can contribute to the ecological component of Environmental Impact Assessment (EIA).
If your project, be it a residential development through to mineral extraction, has potential to impact IEFs, please get in touch with our team of experienced ecologists.

Local Planning Authorities (LPAs) usually require EcIA reports to determine planning applications, to identify if the project will result in any significant effects (i.e. those likely to undermine or support the biodiversity conservation objectives for IEFs).
EcIAs are based on data collected from baseline surveys for habitats (i.e. Preliminary Ecological Appraisals (PEA), UK Habitat Classification surveys), desk studies and protected species surveys undertaken at your site. The extent to which habitat and protected species surveys (e.g. for bats, reptiles, great crested newts, birds, riparian mammals) will be required will be dependent on the habitats present, their potential to support important species and the potential impacts to IEFs as a result of the proposed development.
Minimising impacts for nature and for your project
Once our team of experienced ecologists has established the baseline, we will work with you to design a scheme which avoids/minimises potential impacts on IEFs and legally protected species, provides Biodiversity Net Gain (BNG) and delivers your end goal.
Corylus Ecology follows the EcIA approach as detailed within ‘Guidelines for EcIA’ produced by the Chartered Institute of Ecology and Environmental Management (CIEEM).
