Eigenfeature‐enhanced deep learning: advancing tree species classification in mixed conifer forests with lidar

open access: yesRemote Sensing in Ecology and Conservation, EarlyView.
Workflow for tree species classification using lidar data. Steps include preprocessing (normalization, noise removal, CHM creation), tree segmentation, eigenfeature extraction, and 2D CNN training/validation. Blue, yellow, and red indicate training, validation, and testing image sets, respectively.

Quantifying aboveground herbaceous biomass in grassy ecosystems: a comparison of field and high‐resolution UAV‐LiDAR approaches

open access: yesRemote Sensing in Ecology and Conservation, EarlyView.
The abundance of herbaceous vegetation in grassy ecosystems—which cover >25% of the world's land surface—is highly variable and impacts key ecological processes including carbon sequestration and support for grazing wildlife and livestock. Here, we present a method for using high‐resolution, UAV‐borne Light Detection and Ranging (LiDAR) to estimate ...

Incorporating Sustainability in Defense Projects: Evidence From Norway

open access: yesSustainable Development, EarlyView.
ABSTRACT This study examines how sustainability is incorporated into major defense projects in Norway—a sector that significantly contributes to public spending, resource use, and emissions. Stakeholder theory is applied to analyze sustainable project management (SPM) and its relationship to the UN Sustainable Development Goals (SDGs).
