TER-consult

What TER-consult does

TER-Consult is a Belgian environmental engineering consultancy founded in 2015 in Saint-Nicolas (Liège) by five bio-engineers who met at Gembloux Agro-Bio Tech in 2003. The firm operates four service poles — Sylviculture et Agronomie, Nature, Arbre (Tree), and Eau (Water) — delivering technical studies, expert assessments, private and judicial expertise, and project-management assistance. Its primary client base is Belgian public authorities (communes, provinces, regional administrations such as Bruxelles Mobilité, SPW, AWaP, Ville de Herve, Province de Liège), supplemented by infrastructure operators (Infrabel, Aéroport de Liège), educational institutions (ULiège), and private property owners; the customer roster is heavily government-oriented and concentrated in Wallonia and Brussels.

The firm's core technology stack combines specialized diagnostic instrumentation (PICUS 3 sonic-wave tomography, IML-RESI resistograph, PICUS Treeqinetic traction testing, DJI drone-based remote sensing, aerial-work-platform operation) with a proprietary MATER suite of mobile applications covering intervention management, condition assessment, continuous tree inventory, biodiversity-index calculation (IBA), standardized diagnostic-test workflows, post-failure analysis, and a pathogen database (96+ species in Belgium and France). TER-Consult has also developed two standalone methodologies — the ASUA soil-tree adequacy protocol and the IBA (Indice Biodiversitaire de l'Arbre) — which together codify the firm's field practices into reusable IP.

The business model is project-based professional consulting. Revenue is generated through discrete engineering assignments and government procurement contracts, supplemented by professional training programs (UniversiTER Arbo-Expert) and select subcontractor roles on regional research consortia (Deadwood 4 Forests, iDROC). Pricing is not publicly disclosed and the firm does not publish financial information. The ownership structure is founder-controlled under a co-management/horizontal governance model with no external investors, parent company, or subsidiaries disclosed. Certifications creating procurement and judicial-admissibility barriers include Agrégation 1G3, sworn judicial expert status, polluted-soil expert agrément, wildlife-damage expert designation, European Tree Technician, VETcert, QTRA license, and drone pilot A1/A3.

Core offering

TER-consult is a Belgian environmental engineering consultancy delivering technical studies, expert assessments, private and judicial expertise, and project-management assistance across four service poles: Sylviculture & Agronomie (forestry, agriculture, wildlife damage), Nature (ecological restoration, habitat management, environmental impact assessment), Arbre (phytosanitary and biomechanical tree diagnostics, stability testing, tomography, urban tree management), and Eau (hydrology, hydraulic infrastructure, aquatic environment management). Work is supported by proprietary mobile applications (the MATER suite) and protocols (IBA biodiversity index, ASUA soil-tree adequacy protocol).

Product overview

TER-Consult is a Belgian engineering consultancy offering four core service lines — Sylviculture et Agronomie, Nature, Arbre (Tree), and Eau (Water) — supported by a suite of proprietary digital tools collectively called the MATER applications. The MATER suite includes MATER Intervention (multi-user mobile app for field intervention tracking on tree heritage), MATER Constat (condition assessment), MATER Arbres (continuous inventory and Integrated Tree Value calculation), MATER IBA (Biodiversity Interest Index calculation), MATER Interventions (end-to-end intervention management), MATER Analyses complémentaires (standardized implementation of traction tests, tomographies, resistographies, crown inspections), MATER Crash (post-failure dissection analysis), MATER Haubans (guying system management), and MATER Pathogènes (pathogen database for Belgium and France covering 96+ tree pathogens). The company also developed the ASUA protocol (Urban Soil-Tree Adequacy Analysis) and the IBA (Tree Biodiversity Index) as standalone methodologies. Services are delivered by a team of bio-engineers specializing in forestry, arboriculture, hydrology, and environmental management.

Direct peers

• Arbonaut: Finland-based forestry and urban tree inventory consulting/software firm offering digital arborist management and tree asset tools — directly comparable to TER-Consult's MATER suite and arboricultural diagnostic services across Northern Europe.
• IDForest: Spanish forestry and environmental consultancy delivering forest inventories, ecological assessments, and biodiversity studies — comparable service mix across forestry, hydrology, and nature-conservation consulting in a European public-sector context.
• NatureForest: European forestry and environmental engineering consultancy providing forest management, biodiversity, and ecological restoration services — comparable four-pole mix of silviculture, nature, tree, and water services to public clients.
• Nibuxs: Dutch consulting firm specializing in urban green, tree management, and biodiversity inventories for municipalities — comparable target market (public-sector green asset management) and similar integration of field diagnostics with digital tools.

Regional players

• Arbo-conseil: Belgium-based arboricultural consulting firm offering tree risk assessments, inventories, and management plans — comparable niche expertise but operating across Belgium rather than focused on Wallonia/Brussels.
• Bureau Beeldig: Belgian consultancy specialized in ecological renaturation, hydrology, and landscape planning — overlapping with TER-Consult's Eau and Nature poles and competing for the same Walloon/Flemish public contracts.

Broad incumbents

• EcoStruxure (Schneider Electric): While primarily an industrial platform, Schneider's environmental/ESG advisory arms and broader ecosystem of digital environmental tools represent the type of broad incumbent that could encroach on municipal environmental-tech engagements over time.

Others

• Esri Belgium: GIS platform provider whose technology underpins TER-Consult's mapping work (SIG expertise cited among founders); an enabling technology vendor that could either partner with or substitute for parts of the MATER workflow.
