Cloud Forest Trees Depend on Fog

Cloud Forest Trees Absorb Water Through Their Leaves From Fog

Trees in Costa Rica, as well as a number of plant species, in the tropical cloud forests quench their thirst by directly ingesting fog droplets through their leaves. These forests are in danger because of climate change, and a new study indicates that they’re even more fragile than previously thought.
