Biodiversity Baseline Surveys

Assessing the initial quality of your site's species and habitats

A Biodiversity Baseline Survey is an initial assessment of the species, habitats, and ecosystems in a specific area before any significant development or interventions occur. It establishes a reference point against which future changes in biodiversity can be measured.

Our baseline surveys use the DEFRA biodiversity metric scheme to

• Quantify the biodiversity value of a site
• Identify key species, habitats, and ecosystem services to monitor
• Calculate the number of biodiversity units the site can produce.
• Assess habitat size, condition, distinctiveness, strategic significance, temporal risk, spatial risk

Our data will report on

• Species identification (richness, abundance, diversity, protected species)
• Habitat characterisation (forest, wetland, grassland types)
• Environmental parameters (soil type, water quality, climate).
