Where Biodiversity Net Gain applies, an HMMP is required to legally secure how habitats will be managed and monitored for 30 years after development. In Hampshire, you will need an HMMP if your planning permission includes a biodiversity condition that requires long-term habitat creation or enhancement.
Planning officers in Hampshire most frequently require formal HMMP evidence where development affects or delivers:
If this long-term management evidence is not secured in the correct format, biodiversity conditions cannot be formally discharged.
We provide Habitat Management & Monitoring Plans across Hampshire, including areas such as Winchester, Basingstoke, Farnborough, Southampton, Portsmouth, Andover, Eastleigh, Aldershot, and all surrounding towns, villages, and rural locations across the county.
Planning Authorities across Hampshire require HMMPs to secure the 30-year delivery of habitats created through Biodiversity Net Gain, as set out under the Environment Act 2021. The HMMP provides the legally enforceable framework for management, monitoring and reporting. Without an approved HMMP, long-term biodiversity obligations remain legally unsecured.
We produce Habitat Management & Monitoring Plans aligned to Hampshire‘s policy expectations.
Your HMMP is structured to meet statutory planning requirements in Hampshire and typically includes:
Habitat management objectives and prescriptions — how each habitat will be maintained and enhanced
30-year maintenance schedule — practical, year-by-year actions
Monitoring framework and reporting structure — how success is measured and documented
Legal responsibility and delivery framework — aligned with planning conditions, legal agreements or conservation covenants
This ensures long-term ecological compliance is secured, auditable and enforceable.
Assessment of BNG conditions, site layout and approved biodiversity proposals.
Habitat prescriptions, maintenance actions and monitoring schedules are set out.
Alignment with build-out, handover or responsible body arrangements.
LPA queries or amendments are managed through to approval.

In Hampshire, a Habitat Management and Monitoring Plan is required where development proposals trigger Biodiversity Net Gain and habitat creation or enhancement contributes to approved biodiversity units. Planning decisions are made by district and borough councils such as Winchester City Council, East Hampshire District Council, Test Valley Borough Council and Basingstoke and Deane Borough Council. Developments within the South Downs National Park are determined by the South Downs National Park Authority. The detailed HMMP is typically secured by planning condition and must demonstrate habitat delivery and monitoring for a minimum 30 year period in accordance with approved Biodiversity Metric calculations.
Yes. Developments within or adjacent to the South Downs National Park are subject to heightened scrutiny in relation to landscape character and ecological sensitivity. Habitat proposals must be realistic and compatible with downland soils, exposure and long term countryside management objectives. The HMMP should clearly demonstrate measurable ecological outcomes that reflect the site context.
In coastal districts such as Fareham, Havant and the New Forest fringe, habitat proposals may include saltmarsh, coastal grassland or wetland features. The HMMP must define management prescriptions that reflect saline influence, tidal interaction and long term hydrological conditions where relevant. Unrealistic habitat targets in coastal environments frequently lead to discharge delays.
In most cases, yes. Hampshire authorities commonly attach a pre commencement planning condition requiring approval of the detailed HMMP before works commence. Early preparation is particularly important on strategic housing allocations where habitat delivery forms part of phased infrastructure works.
Common examples include chalk grassland creation, woodland planting, hedgerow enhancement, wetland habitats associated with drainage schemes and retained semi natural habitats. Each habitat must have clearly defined condition benchmarks aligned with the Biodiversity Metric outputs approved at planning stage.
Where proposals involve chalk or calcareous grassland creation, the HMMP must define soil preparation methods, seed mix specification and measurable botanical diversity benchmarks. Establishment assumptions must reflect realistic timeframes for species colonisation and structural development.
Habitat delivery is typically secured through planning condition and may be reinforced through Section 106 agreements or conservation covenants. The HMMP must clearly identify the responsible management party and funding mechanism for the full 30 year obligation period.
Monitoring schedules should include early establishment checks and periodic surveys across the 30 year management term. The HMMP must clearly define survey timing, performance indicators and reporting procedures to the relevant authority.
Delays often arise where habitat targets are not measurable, soil conditions are not adequately considered or the HMMP does not align precisely with the approved Biodiversity Metric calculations. Proposals affecting sensitive downland or coastal environments are typically subject to higher scrutiny.
ProHort prepares technically robust Habitat Management and Monitoring Plans tailored to Hampshire district and National Park authority expectations. We ensure habitat targets are realistic for chalk, woodland and coastal environments, monitoring frameworks are clearly structured and long term stewardship arrangements reduce risk at condition discharge across the full 30 year management period.
