A nature park, or sometimes natural park, is a designation for a protected natural area by means of long-term land planning, sustainable resource management and limitation of agricultural and real estate developments. These valuable landscapes are preserved in their present ecological state and promoted for ecotourism purposes. In most countries nature parks are subject to legally regulated protection, which is part of their conservation laws. In terms of level of protection, a category "Nature Park" is not the same as a "National Park", which is defined by the IUCN and its World Commission on Protected Areas as a category II type of protected area. A "Nature Park" designation, depending on local specifics, falls between category III and category VI according to IUCN categorization, in most cases closer to category VI. However some nature parks have later been turned into national parks.
