Warming world could push Southeast Asia forests toward thermal limits, new study

– Countless forest-dwelling species depend on the cooler, moister and more stable conditions found in the understory, beneath leafy tree canopies.
– A new study from Southeast Asia finds the combined pressures of global warming and habitat degradation could send forest understory heat levels soaring within the next three decades, potentially exposing species to unprecedented levels of thermal stress.
– The findings can help prioritize conservation action on vulnerable landscapes, intact forests and heat-resilient areas that could become important refuges for forest species, the research team says.
– Experts say gaining a fuller picture of how forest-dwelling species will be affected by climate change will ultimately require further studies that consider additional factors, such as humidity, wind and ecosystem feedbacks.

Cutting back vines lets recovering forests grow faster, Borneo study shows

– A new study in Borneo finds that cutting lianas increases canopy height in regenerating logged forests three times faster than tree planting alone.
– Lianas are fast growing woody vines that are a key part of tropical forests, but can proliferate in logged or disturbed forest.
– Researchers around the world are exploring how removing or thinning lianas by cutting their stems influences forest regeneration.
– Using Light Imaging Detection and Ranging (LiDAR) data, the new study found that accelerated tree growth and lower tree mortality contributed to increased canopy height following liana cutting.
