Monitoring Canopy Height in the Hainan Tropical Rainforest Using Machine Learning and Multi-Modal Data Fusion

open access: yesRemote Sensing
Biomass carbon sequestration and sink capacities of tropical rainforests are vital for addressing climate change. However, canopy height must be accurately estimated to determine carbon sink potential and implement effective forest management.

ENVIRONMENTAL VARIABLES ASSOCIATED WITH INVASIVE GLOSSY BUCKTHORN (FRANGULA ALNUS MILL.) AND INDIRECT CONTROL STRATEGIES FOR FOREST MANAGERS [PDF]

open access: yes, 2016
Glossy buckthorn (Frangula alnus Mill.) is one of the most prominent non-native invasive plant species affecting New England forests. It quickly invades a forest and can create a dense understory effectively altering the species composition and dynamics

Spatial Variability of Permafrost and Active Layer Thickness in a Forested Hillslope of the Taiga Shield

open access: yesPermafrost and Periglacial Processes, EarlyView.
ABSTRACT Under continued climate warming, understanding present‐day permafrost distribution and the controls on ground thaw are critical for predicting permafrost thaw trajectories and associated implications. This study presents a high‐resolution investigation of permafrost extent and active layer thickness (ALT) across a coniferous forested hillslope

Agroforestry and enhanced rock weathering: A dual strategy for sustainable cacao

open access: yesPLANTS, PEOPLE, PLANET, EarlyView.
Cacao production is both economically vital and environmentally intensive, presenting a major sustainability challenge as a crop largely cultivated by smallholder farmers in climate‐vulnerable regions. This review synthesises evidence that integrating agroforestry with enhanced rock weathering (EW) may significantly reduce emissions from cacao ...

Made in the shade: Leaf responses of native wildflowers to single‐axis photovoltaic solar energy

open access: yesPLANTS, PEOPLE, PLANET, EarlyView.
As solar energy expands globally, balancing renewable power generation with biodiversity and ecosystem health has become an urgent challenge. This study investigated how native wildflowers respond at leaf level to the unique microclimates created by rotating solar panels in California's Central Valley.

Upscaling Forest Canopy Height Estimation Using Waveform-Calibrated GEDI Spaceborne LiDAR and Sentinel-2 Data

open access: yesRemote Sensing
Forest canopy height is a fundamental parameter of forest structure, and plays a pivotal role in understanding forest biomass allocation, carbon stock, forest productivity, and biodiversity. Spaceborne LiDAR (Light Detection and Ranging) systems, such as

Forest drought resistance distinguished by canopy height

open access: yesEnvironmental 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

MODERATE SEVERITY DISTURBANCE HAS SIMILAR EFFECTS ON THE PRODUCTION OF THREE FORESTS NESTED WITHIN THE UPPER GREAT LAKES LANDSCAPE [PDF]

open access: yes, 2017
Moderate severity disturbances, which only kill a subset of canopy trees (e.g., via insects, pathogens, and windthrow), are increasingly widespread, and can alter forest structure and production.

Integrating indigenous crops in agroforestry systems: Lesser yam and teak mixed systems are more profitable than monocultures in Indonesia

open access: yesPLANTS, PEOPLE, PLANET, EarlyView.
Major staple crops are often introduced and cultivated in monocultures. Yams are staple crops native to the majority of low‐ and middle‐income countries and can provide an alternative to introduced staple crops. We showed that lesser yams cultivated together with teak trees (planted at the border of the farm) are more profitable than lesser yam ...
