Forest drought resistance distinguished by canopy height [PDF]

Environmental Research Letters, 2018
How are the survival and growth of trees under severe drought affected by their size? While some studies have shown that large trees are more vulnerable to drought than smaller trees, others found that small trees are the more vulnerable. We explored the

Canopy Height Estimation Using Sentinel Series Images through Machine Learning Models in a Mangrove Forest [PDF]

Remote Sensing, 2020
Canopy height serves as a good indicator of forest carbon content. Remote sensing-based direct estimations of canopy height are usually based on Light Detection and Ranging (LiDAR) or Synthetic Aperture Radar (SAR) interferometric data.

Canopy Density and Roughness Differentiate Resistance of a Tropical Dry Forest to Major Hurricane Damage [PDF]

Remote Sensing, 2021
Tropical dry forest is vulnerable to increased climate variability with more frequent and severe storms. Studies of hurricane impact on tropical dry forest often focused on individual tree traits. How trees in tropical dry forests work together to combat
