Abstract

When people think of forestry, they usually picture muddy boots, measuring tapes, and chainsaws, but today’s modern forester is just as likely to be found writing Python scripts and querying geospatial databases. The forestry sector is currently experiencing a quiet revolution fueled by an explosion of free and open-source data, transforming how we monitor, measure, and manage complex woodland ecosystems.

This keynote explores the transition from traditional, localized forest inventories to the vast, open-source data ecosystem now available to researchers and practitioners. We will dive into the wealth of global datasets reshaping forest management, including high-resolution canopy height models from Meta and other tech giants, comprehensive datasets from the Horizon Europe PATHFINDER project, and satellite-derived products for biomass estimation from missions like GEDI.

Focusing on a case study in the diverse and challenging landscapes of Romania, we will demonstrate how these massive open-source datasets can be fused with local forest management data to create a comprehensive understanding of forest structure and health. We will explore the practical realities of integrating varied data sources, bridging the gap between global satellite observations and ground-level realities, to support sustainable forest management under climate change scenarios. Ultimately, this talk will prove that digital twinning in forestry is no longer just a buzzword, but an accessible reality powered by the global open-source community.

Bio

Mihai Daniel Nita is a Professor at the Department of Forest Engineering, Faculty of Silviculture and Forest Engineering, Transilvania University of Brasov, Romania. He specializes in remote sensing, GIS, and watershed management, teaching both undergraduate and master’s courses in these fields. He is part of Transilvania University Doctoral School as PhD supervisor. Professor Nita is also a shareholder of Forest Design SRL, a company specializing in forestry services and sustainable forest management.

With a PhD in Silviculture and extensive experience in forest engineering, Professor Nita has led and contributed to numerous national and international research projects focusing on forest management, ecological monitoring, and environmental policy. His research includes innovative use of historical satellite imagery, such as Corona spy satellite photographs, to analyze forest cover changes and inform conservation strategies. His projects span multiple continents, including North America (USA), Central America (Cuba), South America (Guyana, Suriname), Africa (Gabon, Sierra Leone), Asia (Vietnam, Laos, Thailand, Kazakhstan), Oceania (Fiji) and Europe (Romania, Germany, Finland).

He was a Fulbright Visiting Professor at the University of Wisconsin-Madison and currently serves as a corresponding member of the Academy of Agricultural and Forestry Sciences “Gheorghe Ionescu-Sisesti.” Additionally, he holds editorial roles for scientific journals and actively participates in workshops and seminars related to geomatics and environmental science.
