Long-term vegetation changes in elephant-related areas of concern in Kruger National Park, South Africa. [PDF]

Ecol Appl
Abstract African elephants, whether alone or in combination with other environmental factors such as floods, droughts, fire, and other herbivores, have significant impacts on large savanna trees, often contributing to declines over time. However, their effects on woody vegetation in general remain less well understood.

Using simulated GEDI waveforms to evaluate the effects of beam sensitivity and terrain slope on GEDI L2A relative height metrics over the Brazilian Amazon Forest

Science of Remote Sensing, 2023
The vertical structure of forests provides important parameters for estimating aboveground biomass (AGB) and it can be measured by lidar sensors. The Global Ecosystem Dynamics Investigation (GEDI) full-waveform lidar sensor collects data systematically ...

Spaceborne LiDAR for characterizing forest structure across scales in the European Alps

Remote Sensing in Ecology and Conservation, 2023
The launch of NASA's Global Ecosystem Dynamics Investigation (GEDI) mission in 2018 opens new opportunities to quantitatively describe forest ecosystems across large scales. While GEDI's height‐related metrics have already been extensively evaluated, the
