4.01.00 - Forest mensuration and modelling



2nd North American Mensurationists Conference

Portland, Oregon, USA; 11-14 December 2022
IUFRO Units involved: 4.01.00, 4.03.00

The North American biometricians are geographically separated into three regions: southern (SOMENS), northeastern (NEMO), and western (Western Mens). Each region holds individual meetings each year, sometimes in conjunction with other organizations. In the late 1980s, the first continental event was held in Saint Louis, MO. After more than three decades, the three regions decided that a new continental event should be held.

The 2022 North American event will present traditional biometrics and forest measurements techniques as well as novel modeling methods, such as machine learning, or forest inventory based on phodar or UAV (to list just a few). The event captured the interest of two research groups from the IUFRO Division 4 (Forest Assessment, Modelling, and Management), namely the 4.01 (Forest mensuration and modeling) and the 4.03 (Uncertainty analysis, computational ecology, and decision support), which co-sponsor the conference.

State of Knowledge

Forest mensuration (also called forest measurements) has undergone a number of important changes in recent years.  Electronic measuring devices using laser or ultrasound emissions have become commonly used to measure distances.  These devices have reduced the time to measure tree heights considerably, and can be used to quickly obtain other tree parameter measures including spatial positions.  Ground Positioning Systems (GPS) that triangulate satellites to determine ground positions have become widely used.  Read more
