Asynchronous Coupling Between China's Forest Canopy Structure and Belowground Biomass Carbon in the 21st Century

Land Degradation &Development, Volume 37, Issue 14, Page 10127-10146, 30 August 2026.
ABSTRACT The spatio‐temporal relationship between Forest Canopy Structure (FCS) and Belowground Biomass Carbon (BGBC) is fundamental to determining how optimizing spatial structure can maximize forest carbon‐sink potential in land management. However, the lidar data resolution over the space and time exists limitation, causing the coupling relationship

Evaluating and comparing the performance of ICESat-2 and GEDI data for estimating aboveground biomass in mangroves

International Journal of Digital Earth
The launch of the ICESat-2 and GEDI spaceborne LiDAR missions has provided new opportunities for large-scale estimation of mangrove aboveground biomass density (AGBD); however, their footprint-scale performance remains unclear.

The contribution of small trees to carbon stocks along a recovery gradient in the Amazonia

Ecosphere, Volume 17, Issue 8, August 2026.
Abstract Most ecological knowledge about carbon recovery during natural regeneration in tropical regions has focused on individuals exceeding 10 cm in diameter. However, the contribution of smaller individuals to aboveground carbon (AGC) across successional gradients remains poorly quantified, despite their potentially substantial role during early ...

A primer on forest structure measurement with lidar for ecologists

Ecosphere, Volume 17, Issue 8, August 2026.
Abstract Light detection and ranging (lidar) technology has fundamentally advanced the way we measure forest structure, facilitating new insights into ecological processes. Lidar for forest ecology applications is deployed on multiple types of platforms that operate from the ground, air, or space, and each has associated strengths and limitations ...
