Predicting tropical tree mortality with leaf spectroscopy [PDF]

Biotropica, 2020
AbstractDo tropical trees close to death have a distinct change to their leaf spectral signature? Tree mortality rates have been increasing in tropical forests, reducing the global carbon sink. Upcoming hyperspectral satellites could be used to predict regions close to experiencing extensive tree mortality during periods of stress, such as drought ...

Triggers of tree mortality under drought [PDF]

Nature, 2018
Severe droughts have caused widespread tree mortality across many forest biomes with profound effects on the function of ecosystems and carbon balance. Climate change is expected to intensify regional-scale droughts, focusing attention on the physiological basis of drought-induced tree mortality.

It Takes A Stewardship Village: Is Community-Based Urban Tree Stewardship Effective?

Cities and the Environment, 2010
It is believed that involving the public in street tree (i.e. curbside or sidewalk tree) stewardship is an essential part of achieving urban forest canopy goals. However, the incremental benefits of such involvement have not been well studied.

Western Spruce Budworm Effects on Forest Resilience

Plants, 2022
Western spruce budworm (Choristoneura freemani Razowski) is the most destructive defoliator of forests in the western US. Forests in northern New Mexico experienced high levels of WSBW-caused defoliation and subsequent mortality between the 1980s and ...

Mapping Multiple Insect Outbreaks across Large Regions Annually Using Landsat Time Series Data

Remote Sensing, 2020
Forest insect outbreaks have caused and will continue to cause extensive tree mortality worldwide, affecting ecosystem services provided by forests. Remote sensing is an effective tool for detecting and mapping tree mortality caused by forest insect ...

Influence of snowpack on forest water stress in the Sierra Nevada

Frontiers in Forests and Global Change, 2023
Higher global temperatures and intensification of extreme hydrologic events, such as droughts, can lead to premature tree mortality. In a Mediterranean climate like California, the seasonality of precipitation is out of sync with the peak growing season.

Crown damage and the mortality of tropical trees [PDF]

New Phytologist, 2018
Summary What causes individual tree death in tropical forests remains a major gap in our understanding of the biology of tropical trees and leads to significant uncertainty in predicting global carbon cycle dynamics. We measured individual characteristics (diameter at breast height, wood density, growth rate, crown illumination and crown form) and ...

Losses of Tree Cover in California Driven by Increasing Fire Disturbance and Climate Stress

AGU Advances, 2022
Forests provide natural climate solutions for sequestering carbon and mitigating climate change, yet are increasingly threatened by increasing temperature and disturbance.

Tropical tree mortality has increased with rising atmospheric water stress [PDF]

, 2022
Evidence exists that tree mortality is accelerating in some regions of the tropics1,2, with profound consequences for the future of the tropical carbon sink and the global anthropogenic carbon budget left to limit peak global warming below 2 °C. However,
