Est. 2004Ecological consulting & environmental programme delivery

Clearing the path for the world's most consequential projects to break ground.

Meridian directs the ecological science, statutory consenting, and field-survey programmes behind major infrastructure, energy, and land-use developments — from baseline through construction to long-term stewardship. We are the firm brought in when the environment is not a checkbox, but the critical path.

01 / Capabilities

A full-lifecycle science and delivery practice, held to evidentiary standards.

Six integrated disciplines under one accountable programme lead. The team that walks the ground writes the evidence that stands up in examination.

C·01
Ecological Baseline & Field Survey

Protected-species surveys, habitat condition assessment, and phased seasonal field programmes designed to survive statutory and judicial scrutiny.

Impact Assessment & EIA

Environmental Impact Assessment, Habitats Regulations Assessment, and cumulative-effects analysis integrated with the engineering design as it evolves.

Statutory Consenting & Advocacy

End-to-end management of applications, examination, and expert-witness advocacy — including DCO, s.36, and cross-border consenting for nationally significant projects.

Biodiversity Net Gain & Nature Markets

BNG strategy, habitat banking, and origination of verifiable natural-capital units — structured to be both ecologically real and institutionally investable.

Programme & Delivery Management

Construction Environmental Management, ECoW supervision, and multi-year mitigation delivery — governed as a capital programme, reported to the board.

Monitoring, Data & Assurance

Long-horizon monitoring, remote-sensing and geospatial analytics, and independently assured reporting for lenders, regulators, and public inquiry.

02 / Sectors

Where the ecological question is load-bearing.

We work where consent risk can halt a project and where the standard of evidence is set by the courts, the lenders, and the regulator.

S·01

Energy & Renewables

Offshore & onshore wind, solar, grid, and transmission — ornithology, marine mammals, and cumulative-effects at scale.

S·02

Transport & Infrastructure

Road, rail, ports, and airports where linear routes cross designated sites and protected habitat.

S·03

Mining & Resources

ESIA to IFC Performance Standards, closure planning, and biodiversity offsets for extractive majors.

S·04

Water & Coastal

Flood alleviation, reservoirs, and coastal realignment — hydro-ecology and habitat creation.

S·05

Land, Estates & Rewilding

Large-estate natural-capital strategy, rewilding, and landscape-scale recovery programmes.

S·06

Public & Sovereign

National agencies and sovereign funds requiring independent ecological governance and assurance.

03 / Method

One evidentiary thread, from first walkover to final assurance.

Four governed phases. Every deliverable is designed to be defensible in examination and legible to a board, a lender, and a regulator at once.

01

Scope & Baseline

We define the ecological question precisely, then design a proportionate field programme against it. Seasonal survey windows, protected-species licences, and data standards are fixed at the outset — because a gap discovered at examination is a project measured in lost quarters.

Scoping opinion · risk registerSurvey design · method statementBaseline report
02

Assess & Design In

Assessment runs alongside engineering, not after it. We resolve impacts by shaping the design — mitigation by hierarchy, avoidance first — so that what reaches the regulator is already a defensible, buildable scheme rather than a problem to be argued.

EIA / HRAMitigation strategyBNG assessment
03

Consent & Examine

We carry the case through determination and examination, providing the expert-witness evidence and regulator engagement that turn a well-built application into a granted consent — at first determination wherever the evidence allows.

Application managementExpert testimonyConsent & conditions
04

Deliver & Steward

Consent is the start, not the finish. We supervise construction, deliver the mitigation and net-gain commitments on the ground, and monitor outcomes across the years the conditions require — with assured reporting the whole way.

CEMP & ECoWHabitat deliveryLong-term monitoring
04 / Assurance

Evidence that holds — under audit, examination, and inquiry.

Our reputation is our permit to operate. Every programme is governed to independent standards and built to withstand the scrutiny of the parties who matter most.

Governance

Chartered & accountable

Work is led and signed by Chartered Ecologists and Environmentalists, with a named programme director accountable to your board for the full lifecycle.

Data integrity

Traceable evidence chain

Every record is captured to a documented field protocol with a full chain of custody — auditable from the point of observation to the published report.

Independence

Lender-grade assurance

We provide the independent ecological assurance that project finance, IFC-aligned lenders, and public examiners require before capital moves.

Ethics

Science before the answer wanted

We do not shape findings to a predetermined outcome. Where a scheme cannot be made consentable, we say so early — and are retained because of it.

05 / Engagements

Selected programmes, anonymised to client agreement.

North Sea · Offshore Wind

Consenting a 2.4 GW offshore wind array through a designated marine zone.

A four-year ornithology and marine-mammal survey programme, HRA, and expert evidence carried through a contested examination — securing consent for a project the market had written off as un-consentable.

ESIA and biodiversity offset for a critical-minerals operation to IFC standard.

Baseline, ESIA to IFC Performance Standard 6, and a quantified No-Net-Loss offset strategy that unlocked $1.8B of development finance from a syndicate that had paused on ecological risk.

Originating investable biodiversity units across a 14,000-hectare estate.

A landscape-scale natural-capital baseline, habitat-bank design, and unit origination that converted a low-yield estate into a verified BNG supply pipeline serving regional infrastructure demand.
