A natural monument is a form of inanimate or animated nature, valuable for scientific, historical and esthetic reasons protected by law. Natural monuments are a part of our national heritage, the same as historical buildings and pieces of art are. They are equally non-renewable and precious so they deserve respect and utmost care. The most frequent in forests natural monuments are the oldest and the biggest trees. In 2012 in Poland we had 11 thousand such monuments, 8,5 thousand of which were trees.
