Protected Species Survey for a Planning Application

  • Planning Applications:

    Udall-Martin Associates Ecological Consultants work includes ecological input into the planning process from initial ecological assessments / appraisals and protected species surveys of the proposed development site for the planning application stage through to designing and implementing ecological mitigation and compensation works to satisfy planning conditions.

    Providing expert ecological advice to tight timescales we aim to make the planning procedure in terms of ecology run as smoothly as possible.

  • Ecological Advice

    The presence of protected species on a proposed development site can be a major constraint to a project as some development activities may need to be licensed. To avoid possible costly delays to the development works programme and alterations to design plans we recommend expert advice from a specialist ecological consultant is sought at the earliest opportunity. If an initial ecological assessment / appraisal of the site (comprising a Phase-1 habitat survey or ecological walk-over survey) is carried out at an early stage of the development process (ideally prior to the design) any further protected species surveys and mitigation works required can be carried out at the appropriate time of year and compensation and enhancement measures included in the project design.

    For a guide to the best times to carry out ecological surveys see our Ecological Surveys Timetable.
