Layer of tree sap from new growth timber in the form of a ring. With the ring-ring on a tree trunk cut off, we can know the tree's age. When we entered the forest, see the fallen tree ring-Count and its annual rings.
We can also find out the weather that has occurred in the past with a view of trees cut. When the width of the ring, it means that in the past often rain. Meanwhile, when the adjacent ring forms, in the past means that the rare rain. However, the tree can grow to the weight in the art, that is when the weather is hot but still moist.
In addition to calculating its annual rings, we can also know the age of the tree with the measure around the tree. Most trees grow with the thickness approximately 2.5 cm per year. So, to be able to know the age of the tree, and measure around the trunk from 1.5 meters below ground. After knowing the tree circumference, and divide kelilingnya of 2.5 cm so that the tree age is known. For example, if the tree is around 125 cm, the age of the tree is 50 years (125 divided by 2.5 equal to 50).
