What BioConsult SH does

BioConsult SH GmbH & Co. KG is a privately held German ecological research and consulting firm headquartered in Husum, Schleswig-Holstein, founded in 1998 by Dr. Georg Nehls as a three-person office and grown to 160+ employees across Husum, Hamburg, and (since January 2025) Kiel via the MariLim acquisition. The firm delivers environmental impact assessments, species protection reports (including FFH assessments), ecological construction supervision, and expert reports to onshore and offshore wind developers, transport and marine infrastructure clients, federal and state government agencies, and NGOs such as WWF Germany. Its primary revenue drivers are project-based professional services fees won through direct enterprise sales and competitive tenders, complemented by government-funded research contracts from federal ministries (BMWi, BMU, BfN) and agencies such as the German Environment Agency (UBA).

The company's core technology stack rests on three proprietary or JV-controlled capabilities: the HiDef high-resolution digital video aerial survey system for marine birds and mammals (acquired 2016 via HiDef Aerial Surveying Ltd), the AVES AI-based species-level bird detection and identification system (commercialized through the November 2021 ProTecBird GmbH joint venture with Protectis Air), and the probabilistic Raumnutzungs-Kollisionsrisikomodell for habitat-use and collision-risk assessment (commercialized through the PredictBird GmbH joint venture). BioConsult SH also develops drone-based remote sensing and AI image analysis in cooperation with DFKI, including an Arctic beach-litter monitoring project, and operates vertical-radar-based nocturnal bird migration monitoring (ProBird). The firm's research output includes the PROGRESS (2011–2015) and VISSKA (2021–2023) projects, which underpin accepted industry collision-risk benchmarks such as the cited 99.8% bird avoidance rates and 0.0016–0.002% collision risk figures at offshore wind farms.

BioConsult SH monetizes these capabilities through B2B professional services engagements — environmental consulting, expert reports, ecological monitoring and construction supervision — sold directly by managing directors and senior team leads and won through competitive tendering for both private enterprise (notably RWE Renewables and other wind-energy developers) and public-sector research programs. Revenue mechanics are services-led with project-based fees; pricing is not publicly disclosed. The firm operates within the Alliance for Nature alongside French shareholder Biotope SAS (since 2022) and UK subsidiary HiDef, forming a roughly 800-employee pan-European ecological services group. The firm is led by managing directors Dr. Georg Nehls (founder) and Dr. Thilo Liesenjohann, and holds TÜV Nord certifications for ISO 9001:2015, ISO 14001:2015, and ISO 45001:2023.

Product overview

BioConsult SH is an ecological research and consulting company offering a portfolio of environmental services, research projects, and AI-enhanced technologies for wildlife monitoring and wind energy environmental assessment. The core offerings include environmental planning and consulting services (expert reports, FFH assessments, environmental impact studies), ecological field research, and specialized monitoring technologies. Key technology products include: (1) AVES – an AI-based bird detection system developed through joint venture ProTecBird for automatic bird identification to prevent wind turbine collisions; (2) PredictBird – a habitat use-collision risk assessment tool developed through joint venture for wind turbine approval processes; (3) the Raumnutzungs-Kollisionsrisikomodell – a probabilistic collision risk model combining habitat use data with turbine collision calculations; (4) AI-powered drone-based beach litter detection for Arctic marine monitoring; and (5) HiDef high-resolution aerial video systems for marine bird and mammal surveys. Services span onshore, coastal, and offshore environments with capabilities including environmental construction supervision, species surveys, passive acoustic monitoring (C-PODs), drone surveys, and research projects like PROGRESS (collision risk), VISSKA (vibratory pile driving impacts), and SPACEWHALE (marine mammals). The company operates as both a service provider and technology developer, with strategic partnerships through Alliance for Nature, HiDef, Biotope, and MariLim forming a European ecological services group.
