While there generally is a consensus on the purpose of bird song – singing is the easiest way of self-promotion and warnings to competitors – the springtime birdsong in early mornings has been explained in several ways. It has for instance been thought that on a calm windless morning when the background rustling is absent the singing reaches further and it is efficient for the birds to warn competitors and attract partners. It has also been proposed that in singing the male birds gobble early morning cool air, because it cools the sexual organs and protects the germ cells from overheating.

One solution is of course that we fetch plants and seeds from a forest nursery, but for smaller areas cheaper and from nature’s point oif view more appropriate solutions can be tested.

What will be the forest of your future does unfortunately not depend on your own wishes only. Nature’s particular traits have to be carefully reckoned with. The soil, the movement of water and the annual changes in water level determine from which tree species a strong and healthy forest will consist. The characteristics of soil and water are vital factors in determining the formation of the underwood vegetation.
