National infrastructure projects are complex, long-term programmes where decisions made at the earliest stages can have a significant impact on cost, programme and deliverability.
While engineering, planning and construction are naturally central to these projects, ecology also has an increasingly important role to play in strategic decision-making.
For developers delivering major transport, energy, utilities and other infrastructure schemes, understanding ecological constraints and opportunities early can help reduce risk, inform design and support a smoother planning and consenting process.
This is where EMEC is helping clients bring ecology into infrastructure planning from the outset.
Bringing ecology into projects early
Large infrastructure projects can span significant areas of land and potentially interact with protected species, habitats, trees, watercourses and other environmental features.
If these considerations are identified late, they can lead to changes in design, additional surveys, mitigation requirements and potential programme delays.
EMEC works with clients to identify these issues early, providing the ecological information needed to support better strategic decisions.
This can include helping clients understand:
- The ecological constraints associated with potential sites and routes.
- Protected and notable species that could influence project design.
- Habitat, tree and watercourse considerations.
- Survey requirements and potential seasonal constraints.
- Opportunities for habitat creation and biodiversity enhancement.
- Ecological mitigation and long-term land management requirements.
By providing this insight at the feasibility and design stages, EMEC helps clients make informed decisions before plans become difficult or costly to change.
Helping Network Rail create a more biodiverse railway
A strong example of EMEC’s ability to deliver ecological support at national infrastructure scale is our work with Network Rail.
Network Rail’s Eastern Region covers approximately 6,000 kilometres of track and 15,688 hectares of land, passing through some of the UK’s most important and diverse landscapes.
EMEC was appointed to lead a Wildlife Trust Consultancies project supporting Network Rail in delivering its Biodiversity Action Plan across the Eastern Region.
This involved coordinating ecological expertise and local knowledge to understand existing biodiversity and identify opportunities to enhance habitats across the railway estate.
The project brought together eight ecologists, a dedicated project manager and engagement manager, working collaboratively with four other Wildlife Trust Consultancies. The team used ecological data, GIS mapping, satellite imagery and stakeholder engagement to build a detailed understanding of biodiversity across the network.
Crucially, EMEC helped translate this information into practical outputs for Network Rail, including Habitat Management Plans, Sectional Asset Plans and Biodiversity Asset Plans.
More than 1,700 stakeholders across 16 counties were engaged, ensuring that local ecological knowledge was incorporated into the strategy.
This is a powerful example of how strategic ecology can support infrastructure management at scale — combining national coordination with local expertise to inform long-term investment and management decisions.
From ecological data to better infrastructure decisions
The Network Rail project demonstrates an important principle for other national infrastructure organisations:
Collecting ecological data is only the starting point. The real value comes from turning that information into practical, actionable decisions.
For infrastructure developers, this could mean using ecological information to influence route selection, identify environmental risks, shape project design or develop long-term land management strategies.
It can also help organisations identify opportunities where infrastructure investment can contribute to wider environmental objectives.
EMEC’s experience working across large and complex estates means we understand the importance of making ecological advicepractical, strategic and relevant to the wider objectives of an infrastructure organisation.
Supporting Biodiversity Net Gain and environmental commitments
The growing importance of Biodiversity Net Gain (BNG) makes this strategic approach even more relevant.
For applicable Nationally Significant Infrastructure Projects in England, mandatory BNG requirements will apply to relevant applications for Development Consent Orders from 2nd November 2026, requiring at least 10% biodiversity gain, subject to the applicable requirements and exemptions.
For infrastructure organisations, this makes understanding the existing biodiversity baseline and identifying opportunities for enhancement increasingly important.
EMEC can help clients assess biodiversity, develop enhancement strategies and integrate habitat creation, restoration and long-term management into wider project planning.
Ecology that supports the whole project lifecycle
EMEC’s role can extend from the earliest stages of feasibility through to implementation and long-term management.
Our work can help clients:
- Identify risk early– understanding ecological constraints before they become project issues.
- Inform design and planning– ensuring ecological information contributes to strategic decisions.
- Support consenting– providing the surveys, assessments and ecological strategies required.
- Deliver biodiversity objectives– translating environmental commitments into practical action.
- Manage land for the long term– developing habitat and vegetation management strategies that support both operational and environmental objectives.
Our Network Rail work demonstrates how this approach can operate across a vast and complex infrastructure estate, bringing together data, ecological expertise, stakeholder engagement and practical management planning.
