You may need an invertebrate survey if your project involves: 

• flower-rich grassland or meadows, typical of Mole Valley and Reigate & Banstead

• wetland edges, marshes, or ditch systems, including areas along the Thames and Wey corridors

• disused quarries or gravel pits, such as those near Dorking and Leatherhead

• brownfield sites with rubble, scrub, and wildflower mosaics, common in Guildford and Woking

• woodland edges or species-rich hedgerows, often present in Surrey Heath and Tandridge

• river corridors, including the River Mole, River Wey, and tributaries of the Thames

• sites identified during a Preliminary Ecological Appraisal (PEA) as having high invertebrate potential anywhere in Surrey

A simple postcode check confirms whether your LPA is likely to request invertebrate evidence. 

You may need an invertebrate survey if your project involves: 

• heathland, acid grassland, or sandy soils (common in Epping Forest, Chelmsford, Harlow)

• chalk or species-rich meadows (North Essex Downs, Colne Valley)

• brownfield or previously developed land with mosaic habitat

• works near ponds, streams, rivers, or wetland edges (Stour, Blackwater, Crouch)

• woodland, hedgerow, or scrub removal

• sites flagged in a PEA as having notable invertebrate potential

A simple postcode check confirms whether your LPA is likely to request invertebrate evidence. 

You may need an invertebrate survey if your project involves: 

• Chalk grassland or species-rich meadows (North Downs, Sevenoaks, Canterbury)

• Heathland, acid grassland or sandy soils (Ashford, Tunbridge Wells, Maidstone)

• Brownfield or previously developed land with mosaic habitat

• Works near ponds, streams, rivers, or wetland edges

• Woodland, hedgerow, or scrub removal

• Sites where a PEA indicates notable invertebrate potential

You may require a Great Crested Newt (GCN) or eDNA survey in Cheshire if your project involves:

• Development near ponds, such as the sand and gravel pits near Northwich

• Farm conversions or agricultural works around Malpas

• Projects near wet grassland, woodlands, or hedgerows, like the floodplain meadows of the River Weaver

• Landscaping affecting ponds, ditches, or drainage features, such as the canal-side ditches near Winsford

• Sites flagged as high GCN potential in areas like the Cheshire Meres and Mosses

• Works during the April–June survey season, e.g., garden ponds in Knutsford

Checking your Cheshire site postcode or location early helps determine whether a survey is needed and keeps your project on schedule.

You may require a Great Crested Newt (GCN) or eDNA survey in Derbyshire if your project involves:

• Development near ponds, such as traditional farmland ponds or quarry pools near Matlock

• Farm conversions or agricultural works around Ashbourne

• Projects near wet grassland, woodlands, or hedgerows, like pasture depressions and connected hedgerow networks in the Peak District

• Landscaping affecting ponds, parkland lakes, or drainage features, such as estate ponds near Bakewell

• Sites flagged as high GCN potential in areas like the Derbyshire Dales

• Works during the April–June survey season, e.g., small ponds on rural properties in Buxton

You may require a Great Crested Newt (GCN) or eDNA survey in Greater Manchester if your project involves:

• Development near ponds, such as canal-side or parkland ponds in Salford.

• Urban greenspace works or landscaping, for example around public park lakes in Stockport.

• Projects near wet grassland, woodland edges, or hedgerows, such as green corridors and field margins in Bolton.

• Landscaping affecting waterbodies, drainage routes, or industrial basins, for example near disused quarry ponds in Oldham.

• Sites identified as having reasonable GCN potential in preliminary ecological appraisals, particularly across suburban-rural fringe areas like Rochdale.

• Works during the April–June survey season, for example on small ponds or wet depressions in Wigan.
