Across Staffordshire, certain landscape features repeatedly lead to PEA requests during planning. These include:

• Trent Valley floodplain around Burton upon Trent and Alrewas — wet ground and riparian habitat often trigger amphibian and bat risk screening 

• Canal corridors along the Trent & Mersey Canal and Caldon Canal — linear habitat frequently linked to bats, birds and water-associated species 

• Former industrial and colliery land around Stoke-on-Trent, Cannock and Rugeley — brownfield mosaic habitats regularly flag invertebrate and reptile potential 

• Older village cores such as Eccleshall, Cheslyn Hay and Stone — traditional buildings and mature trees commonly introduce bat and nesting bird risk 

Early clarity preserves decision-making control. Late discovery transfers that control to validation officers and consultees. 

Oldham Council regularly asks for BNG information where development may affect important habitat networks, including:

• River corridors associated with the Medlock, the Irk and their tributaries

• Former industrial sites, mill land and regeneration areas with early stage habitat

• Local parks, woodland fringes and greenspace used by wildlife for movement

• Railway routes, valley systems and other transport corridors that function as continuous habitat links

Well structured and clearly presented BNG evidence helps avoid validation issues and reduces the likelihood of planning delays in Oldham.

Planning officers in Chesterfield most frequently request a formal Biodiversity Gain Plan when proposals interact with:

• Strategic housing and mixed-use growth areas around Brimington, Staveley, Whittington Moor and Newbold, where planned expansion intersects with established habitat corridors and green infrastructure.
• Regeneration and former industrial land within the town centre, the Waterside redevelopment zone, Hasland and Sheepbridge, where baseline habitats—especially scrub, early-successional vegetation and riparian edges—are often undervalued.
• Greenfield release and settlement-edge development near Hasland, Calow, Tapton and Boythorpe, where transitional farmland, hedgerows and semi-improved grassland hold notable ecological function.
• River corridor, floodplain and wetland networks linked to the River Rother and its tributaries, including wet woodland pockets, marshy grassland and connected riparian features that strongly influence BNG outcomes.

Planning applications are frequently delayed when the Biodiversity Gain Plan is missing, incomplete or incorrectly formatted, particularly where proposals sit within or adjacent to the River Rother corridor or an active regeneration zone.

Planning officers in Sandwell often request BNG information where development could affect critical habitats. Typical examples include:

• River corridors, such as the River Tame, Smethwick Canal, and associated floodplain habitats
• Brownfield land, particularly in Oldbury, Tipton, and Rowley Regis, supporting regenerating scrub and grassland
• Green corridors, including parks and linear links between residential areas and the canal network
• Rail-adjacent habitats, where embankments and disused tracks provide structurally diverse vegetation supporting invertebrates and small mammals

Clear and correctly presented BNG evidence is essential, as planning applications may otherwise face validation issues or delays.

• Canal and river corridors linked to the Trent & Mersey Canal and River Trent

• Regenerating former industrial and agricultural sites with early-stage habitat

• Suburban woodland edges, green corridors and parks connecting neighbourhoods

• Valley bottoms, stream corridors and the district’s extensive network of pathways

Planning officers in Solihull often request BNG information where development may impact important ecological networks. Typical examples include:

• River corridors, such as the River Blythe and River Cole, including associated floodplain habitats
• Brownfield land, particularly in Shirley, Olton, and Chelmsley Wood, supporting regenerating scrub and grassland
• Green corridors, including linear parks, green wedges, and urban parks connecting neighbourhoods
• Rail-adjacent habitats, where embankments and disused railway corridors provide valuable habitats

Clear and correctly presented BNG evidence is essential, as planning applications may otherwise face validation issues or delays.

Planning officers in Ilkeston most frequently request a Biodiversity Gain Plan when proposals interact with:

• Former industrial and made-ground parcels across the Erewash Valley, including sites near Gallows Inn, Cotmanhay and Hallam Fields

• Regenerating brownfield land with scrub, young woodland or tall herb mosaics linked to historic mining and manufacturing activity

• Settlement-edge greenfield release areas around West Hallam, Kirk Hallam and Little Hallam

• Linear ecological corridors formed by the Erewash Canal, River Erewash, old mineral routes and the rail line that supports wildlife movement

• Floodplain and wetland margins with elevated baseline value, particularly where development may affect connectivity between riparian habitats

Planning applications in Ilkeston often face validation delays where baseline habitats or metric calculations are incomplete, unclear or submitted in non-standard format.

Planning officers in Stafford regularly request BNG where development may affect local habitat networks. Examples include:

• River corridors such as the River Sow

• Former industrial and agricultural land undergoing natural regeneration

• Urban green spaces, tree belts and parkland used by wildlife

• Stream corridors, drainage channels and rail-side habitat routes

Clear BNG evidence helps keep planning applications on track.

Planning officers in Manchester commonly request Biodiversity Gain Plan evidence where development may affect:

• Urban regeneration and housing areas across Manchester and Salford

• Brownfield and former industrial land in towns such as Bolton, Oldham and Rochdale

• Major transport and logistics schemes linked to the M60, M62, M56 and key rail routes

• River and canal corridors, floodplain habitats and wider green infrastructure

Incomplete or unclear Biodiversity Gain Plan information often leads to validation delays or added conditions later in the process.

• Heathland edges and woodland linked to Cannock Chase

• Former mining, industrial and depot sites with natural regeneration

• Urban greenspace, parkland and habitat corridors through neighbourhoods

• Railway verges, stream lines and valley bottoms supporting wildlife movement
