"In mixed forests all the species of trees have different root systems. There are flat-rooted, heart-rooted and deep-rooted trees. The root zone is thus widely diversified and reaches a depth of about 5 metres. Such a forest cannot be torn apart by storms."
Aloys Kokaly, Implosion Magazine No. 54/55, p. 39.
"In the growing season, 1 hectare of forest evaporates about 50,000 litres of water, or 50 m3 per day. in the process a quantity of heat will be extracted through evaporative cooling, which is sufficient to cool 3 million litres of water by 10°C. The sap in the stomata under the surface of the leaves is over-cooled, thereby becoming heavier and sinks down to the root-area, which it then cools, creating a zone of coolness, whereas the warmer and lighter sap rises in the sap ducts. (From an infinite number of the tiny stomata in the leaves and needles, which represent the finest imaginable sieve, the spiralling light ray draws out the minute particle of water and screws it up into the sky.)"
