Forest facts

                               
Did you know 30 per cent of the world's forests are used for the manufacturing of wood and non wood products, and that 1.6 billion people depend on forests for their living.

German black forests

                       

                          Black  forests
Germany's black forest - the schwarzwald - gets it's name from it's dark canopy of evergreens that block out most of the sunlight. This enchanting forests covers hills , valleys , and rivers , that stretch from Swiss spa town of Barden - Barden , to the Swiss border , and from the Rhine almost to lake Constance.
                      
The most common trees are of course conifers , but there are also oaks , maples , and elms . Germany's black forests boast of wild boar , rabbits , deer , pheasants , and more exotic ibex , which lives in the Alpine region.

Plant evolution

                       Plant evolution

About two billion years ago, the very first plants appeared on the planet in the form of minute organisms that inhabited the sea.

The first plants were blue green algae, and took another 1,400,000,000 years to establish themselves at least partly on land .
                       

The first plants were the ancestors of mosses, hornworts, and liverworts , and were very short.  Slowly, plants grew in height to become as large as today's massive ferns. Next, seed bearing plants evolved , forming huge Forest. The next major step in the evolutionary history of plants was much later , when flowering plants known as angiosperms first emerged.
