Lakeland nature and forest mesoregions. A small, peripheral part of the forest lies in the 1st Baltic Nature and Forest Land, namely in parts of the Bytów Lakeland, the Kashubia Lakeland, and the Starogard Lakeland nature and forest mesoregions. According to the European forest classification, the young Scots pine forests and the dry acidophilous Scots pine forests habitats are classified as Nemoral Scots pine forests, while the marshy pine forests are classified as conifer dominated or mixed mire forests. The forest is managed by the Regional Directorates of State Forests in Toruń, Gdańsk, and (a small part only) Szczecinek, with the exception of the territory of the Tuchola Forest National Park, managed outside the State Forests entity by the park itself. A south-eastern fragment of the forest located in the part managed by the Regional Directorate in Toruń has been designated the Tuchola Forest Promotional Forest Complex for the purposes of promoting sustainable forest management. Its primary objective is forest education, in the forms of outdoor lessons and guided tours, classes in forest education chambers, meetings with foresters at schools, meetings outside schools, educational events and actions, exhibitions, forest contests, festivities, fairs, etc., carried out by qualified foresters, known as the leaders of forest education, using dedicated facilities established in the forest, such as education centers, educational chambers, educational shelters, educational trails, educational points, and others. The complex also enables interdisciplinary research based on fully recognized forest environment, for the purposes improvement of forest management methods and setting acceptable limits on economic (commercial) interventions in forest ecosystems. It also allows for sports, recreation and leisure activities in the forest, unhampered by the restrictions typically imposed in a national park or a nature reserve. Environmental protection In June 2010 the Tuchola Forest area was designated by UNESCO as a Tuchola Forest Biosphere Reserve, grossly coextensive with the Tuchola Forest (Bory Tucholskie, PLB220009) and the Great Brda Sandar (Wielki Sandr Brdy, PLB220001) Natura 2000 Special Protection Areas combined, encompassing several smaller Natura 2000 Special Areas of Conservation, such as the Brda and Stążka Valley in Tuchola Forest (Dolina Brdy i Stążki w Borach Tucholskich, PLH040023), the Brda and Chocina Valley (Dolina Brdy i Chociny, PLH220058), the Brda Sandar (Sandr Brdy, PLH220026), the Wda Sandar (Sandr Wdy, PLH040017), Mętne (PLH220034), Wdzydze Lakes (Jeziora Wdzydzkie, PLH220057), the Zapceń Refuge (Ostoja Zapceńska, PLH220077), Młosino-Lubnia (PLH040023), or the Church in Śliwice (Kościół w Śliwicach, PLH040034).
