Across the West Midlands, Preliminary Roost Assessments are most frequently requested where development interacts with:

• Older housing stock in towns like Birmingham, Wolverhampton, and Walsall, where lofts, ridge tiles, and cavity walls can provide potential roost access

• Redundant farm buildings and outbuildings across rural areas of Solihull, Cannock, and Staffordshire border zones

• Brownfield and regeneration sites in Dudley, Sandwell, and Coventry, where legacy structures are retained within new developments

• Linear habitats and green corridors including rivers (Tame, Blythe), canals (Staffordshire & Worcestershire Canal, BCN), hedgerows, and tree belts that intersect development plots

PRA requirements are routinely tested at validation wherever bat roost potential exists.

Across Warwickshire, Preliminary Roost Assessments are most frequently requested where development interacts with:

• Historic residential properties in towns such as Warwick, Leamington Spa, and Stratford-upon-Avon, where loft spaces, slate ridges, and cavity walls can provide bat access

• Rural farm buildings and outbuildings across North and South Warwickshire, particularly older barns and redundant agricultural structures

• Regeneration or brownfield sites in Nuneaton, Rugby, and Kenilworth, where older structures are retained within redevelopment layouts

• Linear natural features including rivers (Avon, Leam), canals (Grand Union Canal), mature hedgerows, and woodland patches intersecting development areas

PRA requirements are routinely tested at validation wherever bat roost potential exists.

Across Greater Manchester, Preliminary Roost Assessments are most frequently requested where development interacts with:

• Older residential and industrial buildings in towns like Manchester, Stockport, Bolton, and Oldham, where lofts, ridge tiles, and cavity walls may offer bat access

• Redundant farm buildings and outbuildings in semi-rural areas of Wigan, Tameside, and Rochdale

• Brownfield or regeneration sites in Salford, Trafford, and Ashton-under-Lyne, where older structures remain within redevelopment layouts

• Natural and linear habitats including rivers (Irwell, Mersey), canals (Manchester Ship Canal, Rochdale Canal), woodland patches, and mature hedgerows that intersect development zones

PRA requirements are routinely tested at validation wherever bat roost potential exists.

Across Yorkshire, Preliminary Roost Assessments are most frequently requested where development interacts with:

• Historic industrial buildings in towns such as Leeds, Bradford, Huddersfield, and Halifax, where old mill roofs, ridge tiles, and brick cavities may provide bat access

• Traditional farm buildings and rural outbuildings across Calderdale, Kirklees, and rural areas of Wakefield

• Regeneration and brownfield sites in Dewsbury, Castleford, and parts of Bradford where older structures are retained within new developments

• Linear and semi-natural habitats including the Aire, Calder, and Wharfe rivers, canal corridors, woodland patches, and mature hedgerows intersecting development zones

PRA requirements are routinely tested at validation wherever bat roost potential exists.

Across Kent, Preliminary Roost Assessments are most frequently requested where development interacts with:

• Historic buildings and structures in towns like Canterbury, Rochester, and Maidstone, where roof voids, chimneys, and loft spaces provide bat access

• Farm buildings and agricultural barns across the Kent Downs, particularly those near orchards, hedgerows, and traditional farmsteads

• Brownfield and regeneration sites in areas such as Ashford, Folkestone, and Medway, where older industrial structures are incorporated into new developments

• Natural and linear habitats including the River Medway, Kent’s extensive network of coastal marshes, and the ancient woodlands in areas like the Weald, which intersect with urban and rural development zones

PRA requirements are routinely tested at validation wherever bat roost potential exists.

Across Surrey, Preliminary Roost Assessments are most frequently requested where development interacts with:

• Historic and period properties in towns like Guildford, Woking, and Farnham, where older roof structures, chimneys, and loft spaces provide bat roosting opportunities

• Rural farmsteads and barns in the Surrey Hills and other countryside areas, where traditional agricultural buildings, outbuildings, and older barns may support bat roosts

• Brownfield and regeneration sites in towns like Epsom, Redhill, and Staines, where older industrial buildings remain within new development plans

• Natural corridors and habitats including the River Wey, the Mole, and the Thames, as well as wooded areas like those found in Frensham Great Pond and Wisley Common, which intersect with urban and rural development zones

PRA requirements are routinely tested at validation wherever bat roost potential exists.

Across Hampshire, Preliminary Roost Assessments are most frequently requested where development interacts with:

• Historic and period properties in towns like Winchester, Basingstoke, and Southampton, where older buildings, roof voids, and brickwork gaps present bat roosting opportunities

• Agricultural buildings and barns in rural areas such as the New Forest, East Hampshire, and the Test Valley, where traditional barns and farm structures provide potential bat habitats

• Brownfield and regeneration sites in urban areas like Portsmouth, Andover, and Havant, where older industrial and commercial buildings remain within redevelopment plans

• River corridors, wetlands, and coastal areas including the River Itchen, Solent coastline, and areas of heathland and woodland, which intersect with both rural and urban development zones

PRA requirements are routinely tested at validation wherever bat roost potential exists.

Across Essex, Preliminary Roost Assessments are most frequently requested where development interacts with:

• Historic residential and commercial buildings in towns such as Chelmsford, Colchester, and Southend-on-Sea, where lofts, ridge tiles, and cavity walls provide potential bat access

• Agricultural buildings and farmsteads in rural areas of Braintree, Tendring, and Maldon, particularly older barns and redundant outbuildings

• Brownfield and regeneration sites in Harlow, Basildon, and Clacton-on-Sea, where older structures are incorporated into redevelopment layouts

• Linear and natural habitats including the River Chelmer, Blackwater, and Crouch, woodland patches, and hedgerow networks that intersect urban and rural development zones

PRA requirements are routinely tested at validation wherever bat roost potential exists.

Dudley planning officers most frequently require formal HMMP evidence for developments affecting:

• Urban regeneration and mixed-use projects across Dudley town centre, Brierley Hill, Halesowen, and Stourbridge

• Residential expansion across Sedgley, Netherton, and Kingswinford

• Commercial, logistics, and industrial developments along key corridors including the M5, A456, A4123, and A4101

• Sites adjacent to ecological assets such as the River Stour, Dudley Canal, Wrens Nest National Nature Reserve, and local woodlands

If the HMMP is not provided in the required format, biodiversity conditions cannot be formally discharged.

Planning officers in Walsall most frequently require formal HMMP evidence where development affects or delivers:

• Urban regeneration and mixed-use schemes in Walsall Town Centre, Bloxwich, Willenhall, Darlaston, and Pleck

• Residential growth across Shelfield, Aldridge, and Streetly, including urban fringe expansion

• Commercial, industrial, and logistics development along M6, A34, and A454 corridors

• Sensitive ecological areas such as the River Tame, Walsall Arboretum, Rushall Canal, Reedswood Park, and local woodland networks

If this long-term management evidence is not secured in the correct format, biodiversity conditions cannot be formally discharged.
