For example, in National Parks public access by feet is generally accepted to all parts of parks and berry picking is allowed, while camping may be allowed only in limited parts of the park. In Finland, public access and human activities are most restricted in the so-called strict nature reserves, which are in total 19 different sites in Finland. The purpose of these sites is to protect biodiversity values, but they can also have scientific and/or educational importance. In general, people are only allowed in specific designated paths or areas and without specific permit all other access is prohibited.
