The Life Nieblas project in the Canary Islands uses a plastic mesh to imitate how pine needles trap water, and is used to milk the clouds of fog on the islands for water. The captured water is used to irrigate reforested tree saplings until they are big enough to capture water from the air themselves. The system is also used in Chile to provide drinking water and water for irrigation. The system on Gran Canaria has resulted in a reforestation survival rate of 86%, double that of traditional reforestation.
