Bristol’s urban and peri-urban landscape—including parks, river corridors, wetlands, and former industrial sites—supports a wide variety of invertebrate species.
An invertebrate survey is an assessment of an area to identify which invertebrate species are present. Experts search, observe, and sample habitats over time to determine species diversity, abundance, and conservation importance. The results help ensure that development or land-use changes do not harm invertebrate wildlife and comply with planning and environmental regulations.
You may need an invertebrate survey in Bristol if your project involves:
Loss of wetland or grassland habitats in Redland
Impact on brownfield sites, former industrial areas, or mosaic habitats in Bedminster
Drainage alterations, ditch works, or wetland disturbance in St George
Activities near ponds, streams, or wetland margins in Clifton
Removal of woodland, scrub, or hedgerows in Filton
Sites flagged in a Preliminary Ecological Appraisal (PEA) as having potential for notable invertebrates in Hartcliffe

In Bristol, planning authorities may require invertebrate survey evidence where suitable habitat is present to ensure development complies with the Wildlife & Countryside Act 1981 and national planning policy. Without early, proportionate survey work, planning applications can be delayed due to validation queries, additional conditions, or seasonal restrictions linked to key invertebrate activity periods. These delays can disrupt project programmes and may result in avoidable redesign, highlighting the importance of early, targeted invertebrate assessments.
Our specialist ecology team carries out an invertebrate surveys to assess species presence, habitat use, and any potential risks. You receive a clear, LPA-ready report outlining practical mitigation and timing recommendations, helping your project remain compliant with wildlife legislation and progress

Need an Invertebrate Survey in Bristol? Let’s confirm your site’s requirements and keep your project on track.
Yes. Even relatively small development sites in Bristol can support important invertebrate populations, particularly where there are wildflower areas, brownfield habitats, mature trees, green corridors, rivers or unmanaged grassland. An invertebrate survey determines whether your proposals could impact these species and whether ecological measures are required before planning permission is granted.
An invertebrate survey provides evidence about the ecological importance of a site by assessing its habitats and the insects and other invertebrates they support. Planning officers use this information to decide whether development proposals comply with biodiversity policies and whether mitigation or habitat enhancements should form part of the planning approval.
Yes. Brownfield sites are often underestimated but can provide valuable habitat for many uncommon invertebrates. Areas with exposed ground, rubble, early successional vegetation and flowering plants frequently support diverse insect communities, which is why these sites are regularly assessed during the planning process.
The site visit itself is often completed within a day, although larger or more complex developments may require additional time. If seasonal species need to be surveyed, multiple visits may be recommended across different months to ensure the ecological assessment is accurate and suitable for planning.
In many cases, yes. Finding important invertebrate species does not automatically prevent development. Instead, the survey helps identify practical mitigation measures such as habitat retention, ecological buffers, habitat creation or revised site layouts that allow development to proceed while protecting biodiversity.
Habitats that commonly support significant invertebrate populations include species rich grassland, scrub, riverbanks, wetlands, woodland edges, flowering roadside verges, mature hedgerows, brownfield land, traditional orchards and veteran trees. Ecologists assess both habitat quality and connectivity across the wider landscape.
Yes. Commissioning an invertebrate survey early demonstrates that ecological considerations have been addressed during the design process. This can give planning officers greater confidence in the application and reduce the likelihood of requests for additional ecological information after submission.
Planning applications within the city are administered by Bristol City Council, which may request ecological surveys where development could affect important habitats or protected species. Planning guidance can be found at:
Survey requirements will vary depending on the characteristics of the site and the proposed development.
Following the survey, ProHort prepares a comprehensive report explaining the habitats assessed, survey findings, ecological significance of the site and any recommendations needed to support planning. The report is suitable for submission alongside planning applications and can help inform project design where ecological constraints are identified.
ProHort delivers planning focused invertebrate surveys throughout Bristol using experienced ecologists and recognised survey methodologies. We provide clear, reliable ecological reports that help developers, architects, homeowners and planning consultants understand ecological risks early and keep planning applications moving efficiently.
