Preliminary Ecological Appraisal (PEA)
A Preliminary Ecological Appraisal is usually the first ecological requirement set by a planning authority for proposed developments. Its purpose is to identify all potential ecological receptors on a development site which are of conservation importance, particularly those with legislative implications, and evaluate the constraints which these may pose to the proposals.
Firstly, a desk study of the site will be undertaken including; search of local environmental records data and interpretation of key habitats from online aerial images. Once the desk study has been completed, our ecologists will carry out a walkover survey of the site to assess its potential for species of conservation importance, in accordance with the JNCC guidance for extended Phase 1 Habitat Survey. This involves identification of all habitats and ecological features, and a general search for field signs of legally protected or non-native invasive animal and plant species.
The results of the desk study and field survey are compiled into a concise report complete with a map detailing the locations of ecological features. Maydencroft carries out all work in relation to Preliminary Ecological Appraisals in accordance with BS 42020:2013 Biodiversity – Code of practice for planning and development.
