-Friends: toads, bats
+// Try to reach as high as the lork does //
-Duties: wood is used for fences, bats, staircases, telephone poles
-Character: is a pioneer, the first to come back after the ice age, can survive in very austere environments, did not evolve in reproduction system (gymnosperm (naaktzadige) vs seeds & sperm of the flowering plants), fertilization through wind (vs also insects for flowering plants)
+The larch stands for survival. It was the first species to migrate back north after Ice Age. Larch can survive in very austere environments, but cannot stand heavy pollution. It creates symbiosis with mushroomlike fungi that inhabit its roots in a friendly way and allow the larch to absorb more minerals. Toads and bats are great friends of the larch.

+Larch is the only species of its sort that looses its leafs in winter. Unlike other trees and plants, larch did not evolve into the sophisticated reproductive system of the angiosperms. The gemma of the larch is not entirely covered by the leaves of the flower. There is no pollen tube that leads the way trough the cells in order to reach its destination. And as a consequence, there is no double fertilization, which is typical for angiosperms, where one embryo will survive, while the other one will serve as a food stock for the first one.
+Larch produces one of the toughest woods obtained from conifers and is also resistant to woodworm. It is widely used in construction, for railway sleepers, cabinet work, fences, staircases, telephone poles.
+Large quantities of resin are obtained by tapping the trunk. Small holes are bored into the trunk, most resin being obtained from near the centre of the trunk. When properly made, the same borehole can be used for 20 - 30 years. The resin has a wide range of uses including wood preservatives, varnish, medicinal etc. It needs no preparation other than straining through a cloth to remove plant debris etc. The hole is made in the spring and the resin extracted in the autumn. Resin can be extracted from May to October.
