Sampling forests with terrestrial laser scanning

Terrestrial laser scanners (TLSs) have successfully captured various properties of individual trees and have potential to further increase the quality and efficiency of forest surveys. However, TLSs are limited to line of sight observations, and forests are complex structural environments that can occlude TLS beams and thereby cause incomplete TLS samples. Boucher et al. evaluate […]

Forest above-ground volume assessments with terrestrial laser scanning: a ground-truth validation experiment in temperate, managed forests

Quantifying the Earth’s forest above-ground biomass (AGB) is indispensable for effective climate action and developing forest policy. Yet, current allometric scaling models (ASMs) to estimate AGB suffer several drawbacks related to model selection and uncertainties about calibration data traceability. Terrestrial laser scanning (TLS) offers a promising non-destructive alternative. Tree volume is reconstructed from TLS point […]

Trees alone will not save us

There's more recognition that ecological restoration can be an essential tool in fighting climate change, and there are many projects aimed at restoring degraded forests to capture carbon. Still, the focus on forests ignores much of the land in the tropics that would not naturally be forested. A team of scientists is arguing that people need to become aware of other habitats and their value.
