The political borders are the interest of many branches of science, such as history, politology, law and geography. This is a reason that there are a lot of various classifications and typologies of the borders. The sense of the division of the political borders into the natural and artificial arouses many controversies among the geographers. Generally, the natural borders are consider to run along the mountains, rivers, sea-coasts, etc. Together with the rejection of philosophical conceptions of the geographical determinism, geographers generally stopped taking an interest in natural conditions of the course and the function of the political borders. The geopolitics and argumentation that the natural borders bear little strategical role and are the obstacles in communication, influenced the aversion to using of that term. Nevertheless, some geographers still use the terms: artificial and natural borders. The lawyers lay emphasis on the sense of that classification, noticing the expediency of adding the annexes to the boundary treaties concerning e.g. rivers and lakes lying on the borders. The conventions regarding the preservation and creating of the forest, mountain and desert environments where the borders run, are necessary. The co-ordinated actions concerning the national parks lying near the borders are indispensable. In such understanding, the separation and survey of the natural borders seem reasonable and socially useful.
