P13 Pine at sunset


P13 Pine at sunset

This is a photo of a Canarian Pine (Pinus canariensis)on the Garafia road to the observatory, photographed at sunset.

Canarian pines are amazing. For one thing, they regularly survive forest fires. They can burn for six hours without dying. For another, the pine needles creat much of the island's water supply. The pines grow at an altitude where they frequently sit in the clouds, and the needles evolved to condense out water droplets so that they drip onto the ground above the tree's roots. Depending on which source you believe, a bucket under a pine tree will collect five to twenty times as much water as one out in the open. Maybe it depends on hte exact temperature and relative humidity in the cloud.

Certainly the climate of Gran Canaria has been much drier since they cut down the forest.
