Preliminary Ecological Appraisal
Preliminary Ecological Appraisal
A Preliminary Ecological Appraisal (PEA) is often the first ecological survey undertaken to support planning and development.
Our ecologists assess habitats, review ecological records and identify potential protected species constraints so projects can move forward with greater certainty.
Whether you are preparing a planning application, evaluating land or progressing detailed design, we provide practical ecological advice and clear recommendations that align with programme and planning requirements.
A Phase 1 Habitat Survey, sometimes also referred to as a Preliminary Ecological Appraisal, is a survey that takes on board all the flora and fauna of a site, providing a snapshot of the landscape and surrounding area. An experienced ecologist carries out a Phase 1 survey in order to record all wildlife, inhabitants and any water features that are present on the site. All boundaries are recorded as part of the survey too. This initial phase of survey is the industry standard for all UK ecologists.
A desk study will also be carried out. This looks for records of protected species and habitats that are available online, or provided by biological records centres and protected species groups.
Fish Surveys and Fish Rescue
Safely capture and relocate fish before work to protect aquatic life and habitats.
Protected Species Surveys
Serve to detect legally protected wildlife before works to inform planning.
Biodiversity Net Gain
Quantify habitat losses and gains to secure an uplift in biodiversity.
Invasive Species Surveys
Map and ID non‑native plants to guide land management & protect biodiversity.
River Condition Assessments
Assess river habitat to understand condition and guide restoration.
