What Terra Nostra does

Terra Nostra BV is a Dutch B2B consulting firm founded in 2013 and headquartered in Bleskensgraaf, Netherlands, operating as a 'kennisatelier' (knowledge atelier) for trees and soil. It provides specialized advisory services across tree technical research, smart tree inventories, policy and management consulting, disease and pest management (with a particular focus on Oak Processionary Moth via pheromone confusion methods), tree valuation, diagnostics, and GIS/GEO analysis. The firm serves Dutch municipalities as its primary customer segment, alongside private landowners, construction/development firms, and cultural heritage organizations such as Rijksdienst Cultureel Erfgoed and Bomenstichting. Notable municipal engagements include tree inventories for Gemeente Ede (22,197 trees documented), tree technical research for Gemeente Utrecht, and EPR mating disruption research spanning 24 municipalities and 5 provinces.

The company's technical stack combines specialized diagnostic equipment—Picus sound tomograph, Picus Treetronic, ground-penetrating radar, chlorophyll fluorescence meters, and Air-Spade—with proprietary digital platforms. These include an ArcGIS-based EPR (Oak Processionary Moth) registration system developed in-house and co-participation in Platform i-Tree Nederland alongside 14 municipalities. Through a June 2023 partnership with greehill, Terra Nostra offers 'Smart Tree Inventories®' that fuse lidar and high-resolution camera data with AI-driven analytics to generate 3D tree models and ecosystem services valuations. The firm holds multiple certifications (BRL-Boomverzorging/Groenkeur, ISO 9001, ISO 14001, VCA**, CO2 Performance Ladder Level 5) valid through 2028–2029.

Terra Nostra operates four offices (Bleskensgraaf headquarters, Elsendorp, Amsterdam, Assen) and is part of the NBB-Groep (Nationale Bomenbank), a 50-year-old Dutch tree management conglomerate. Revenue is generated primarily through project-based advisory contracts and a 'Kennisbundel' (Knowledge Bundle) hourly consulting model targeted at municipal and government clients via direct B2B sales and public tenders. As of January 1, 2023, Jan Willem de Groot succeeded founder Henry Kuppen (now Tree Ambassador) as Director. The firm also extends services into Belgium through the greehill partnership.
