One of humankind’s greatest challenges is to ensure sustainable development. Knowledge is crucial to increase environmental awareness, and perhaps more important is the understanding that we all play a role in making a change towards a sustainable development.

Useful tools to find data about forests: Measure tree height This is a description of how to measure the height of a tree, using a stick, a measure band, and simple mathematics. Find a stick that is at least the length of your arm. While keeping a straight arm, hold the stick so that the distance from your hand to the top of the stick, is equal to the distance from your hand to your eye. You can check this by placing the stick along your arm. If the end reaches your shoulder, then the distance is correct.Place yourself in front of the tree you would like to measure. The distance between you and the tree, should correspond to the height of the tree.
