Forests Worldwide near Tipping Point From Drought
by Monga Bay staff
Forests worldwide are at “equally high risk” to die-off from drought conditions, warns a new study published this week in the journal Nature.
The study, conducted by an international team of scientists, assessed the specific physiological effects of drought on 226 tree species at 81 sites in different biomes around the world. It found that 70 percent of the species sampled are particularly vulnerable to reduction in water availability. With drought conditions increasing around the globe due to climate change and deforestation, the research suggests large swathes of the world’s forests — and the services they afford — may be approaching a tipping point.
Water is critical to trees, transporting nutrients, providing stabilizing, and serving as a medium for the metabolic processes that generate the energy needed for a tree to survive.(read more: MongaBay) (photos: Rhett Butler)
It is finally starting to freeze at night on a regular basis - but I have been watering my yard and trees all week - because what we have not had is rain or snow. My house is surrounded by trees and I don’t want them dying or falling on my house. It may be winter, but our drought continues.
