In addition, 2.2 million ha of forest is part of a category called "protected landscape areas". As a result, only around 500 ha of forest (mostly public) is converted to other uses (mostly industrial) each year, pursuant to the 1995 Act on Protection of Agricultural and Forest Land. If there is no master plan, such exclusion may be impossible. A recent report of the Polish Academy of Sciences revealed that only 28% of the territory is subject to plans that define uses for land, such as housing, industrial or green areas (Kowalewski, 2014).
