Preliminary Ecological Appraisal
A Preliminary Ecological Appraisal (often referred to as an Extended Phase 1 Habitat survey) comprises a broad walkover, documenting the baseline ecological value of a site, mapping all habitats, and identifying potential for constraints to, and opportunities for, important ecological features associated to the proposed works.
The appraisal is used to inform the emerging scheme design, enabling significant ecological effects within the zone of influence to be avoided, mitigated, or compensated for, where necessary. This ensures the continued favourable conservation status of protected habitats and species, post development, and ultimately compliance with nature conservation legislation and planning policy.
A site survey is typically supplemented by a desk study, utilising maps and aerial photographs of the surrounding area to identify ecological connectivity, and published records of protected and noteworthy species, purchased from the local records centre.
Requirements for any necessary further targeted habitat or protected species surveys will be identified, and opportunities for ecological enhancement will be outlined, to integrate on-site biodiversity net gain into the scheme at an early stage, where possible.​
Many ecological surveys are seasonally constrained, making it prudent to plan ahead and consider ecological issues early on in the planning process. A robust habitat survey at an early stage in project planning and design can therefore deliver significant benefits, avoiding potentially costly and time-consuming delays.​
When
Preliminary Ecological Appraisals can be undertaken throughout the year, though the optimal season (when habitats can be most accurately appraised) lies between April-September inclusive.
Why Us
With over fifteen years' experience in undertaking ecological surveys, mitigation design, licensing, site supervision, and monitoring, our team of expert ecologists can help guide your project through the planning process.
We can appraise your site in accordance with either Phase 1 Habitat Survey, or UK Habitat Classification methodology, depending on project requirements.
