Invertebrate Surveys
We carry out invertebrate surveys to understand how insects and spiders are using a site - from veteran tree beetles to grassland invertebrates - helping inform conservation decisions and keep projects compliant.
We carry out targeted invertebrate surveys to understand how insect and spider communities are using a site, from conservation assessments to baseline data for development projects.
Invertebrates are among the most sensitive indicators of habitat quality, yet they are frequently overlooked in ecological assessments. Whether it's identifying saproxylic beetle assemblages in veteran trees, assessing the invertebrate interest of unimproved grassland, or establishing pre-development baselines, a robust invertebrate survey can reveal ecological value that other surveys simply won't detect.
We carry out surveys using a range of established methods - including pitfall trapping, sweep netting, beating, and targeted searching - with identification to species level across a range of key groups including Coleoptera, Diptera, Arachnida, and Hemiptera. Results are assessed using the Pantheon database where appropriate, allowing assemblage-level analysis that places findings in a meaningful conservation context. Survey outputs can support Biodiversity Net Gain assessments, SSSI feature condition monitoring, management plan development, and ecological impact assessments.
We tailor survey effort to the habitat and project requirements, focusing on the invertebrate groups most likely to be ecologically significant, and providing clear, evidence-based reporting that is honest about both the value and the limitations of what the data shows.
Our service includes:
• Targeted invertebrate surveys using pitfall traps, sweep netting, beating, and hand searching
• Species-level identification across key groups including beetles, flies, spiders, and true bugs
• Assemblage analysis using the Pantheon database to assess conservation significance
• Surveys to support development, BNG assessments, and SSSI condition monitoring
• Focus on specialist and indicator species associated with key habitat features (e.g. veteran trees, unimproved grassland, wetland margins)
