Enhancing biodiversity and nature market opportunities at Holme Farm
Background
Holme Farm, a 100-hectare mixed farm near Reading in Berkshire, underwent a significant management transition when the land returned from a long-term tenancy agreement to direct owner management. The farm comprised permanent grassland, ancient broadleaved woodland, and arable land previously cultivated with oilseed rape.
Following this transition, the landowner set out to implement regenerative farming practices, strengthen on-farm biodiversity, and explore emerging nature market opportunities, including Biodiversity Net Gain (BNG) and carbon credit schemes. There was also interest in developing community engagement initiatives, such as educational access.
ADAS was commissioned to undertake a comprehensive assessment of the farm, identifying opportunities for habitat enhancement, nature recovery and participation in agri-environment land management schemes and produce an in-depth action plan for the farm going forward.
Objectives
The ADAS assessment aimed to:
- Evaluate the existing environmental baseline and biodiversity condition of the farm
- Identify opportunities for habitat enhancement and diversification
- Assess eligibility for agri-environment schemes and nature market opportunities
- Provide practical recommendations aligned with local priorities and requirements
- Explore options for community engagement and educational land use
- Develop a practical action plan with indicative timescales and guidance on agri-environment scheme applications
Actions taken
ADAS conducted a detailed environmental and land capability assessment – including soil types and biodiversity.
The farm’s soils were predominantly Grade 3 loamy clays, with areas of floodplain meadow located close to the river. The assessment reviewed local water catchment priorities, including reducing sediment loss and pesticide risk.
Several priority habitats were identified, including ancient deciduous woodland and floodplain grazing marsh adjoining the River Loddon Site of Special Scientific Interest (SSSI). The survey work recorded notable and protected species, including red-listed birds such as skylark, marsh tit and yellowhammer, alongside great crested newts and pipistrelle bats.
Results
The assessment provided Holme Farm with a clear, evidence-based strategy for biodiversity enhancement and sustainable land management. ADAS confirmed that the farm was well-positioned to enter agri-environment schemes supporting soil health improvement, hedgerow management and integrated pest management. Higher Tier scheme opportunities were also identified in areas containing historic features.
Multiple habitat restoration and enhancement opportunities were outlined, including hedgerow diversification, wetland creation, woodland management improvements, and orchard establishment to increase ecological resilience and habitat connectivity.
Crucially, ADAS advised that baseline Biodiversity Net Gain and soil testing should be completed prior to implementing any changes. This strategic approach enabled the landowner to safeguard and potentially maximise future income from biodiversity units and carbon credits within emerging UK nature markets.
Overall, the project delivered a comprehensive natural capital assessment at a pivotal moment in the farm’s management transition. It equipped the landowner with the insight and practical roadmap required to balance environmental recovery, regulatory compliance and long-term commercial sustainability.
