The Tuchola Forest, also known as Tuchola Pinewoods or Tuchola Conifer Woods, (the latter a literal translation of ; ; ) is a large forest complex near the town of Tuchola in northern Poland. It lies between the Brda and Wda rivers, within the Gdańsk Pomerania region. The largest towns in the area are Czersk and Tuchola.
The designation may also refer to the eponymous historical land and ethnocultural region, World War II battle, geomorphological mesoregion, phytogeographic landscape region and syntaxonomical subregion, nature and forest mesoregion, promotional forest complex, Biosphere Reserve, Natura 2000 Special Protection Area, national park, LEADER/CLLD local action group, or a number of local associations. Geographical extent varies greatly among these units or entities.
Geography, nature and ecology With 3,200 km2 of dense spruce and pine forest, the area is one of the biggest forests in Poland and Central Europe.
Geomorphology and geology The area was formed during the last glacial age and is covered with low hills and more than 900 post-glacial lakes. From the geomorphological point of view, the area is located in the South-Pomeranian Lakeland macroregion of the South-Baltic Lakelands Sub-Province belonging to the Polish Plain, a part of the North European Plain province. The forest covers the eponymous Tuchola Forest mesoregion, but also the Świecie Plain (both mesoregions sometimes jointly referred to as Tuchola Plain), large swaths of the Charzykowy Plain and the Brda River Valley mesoregions, as well as lesser parts of other mesoregions: the Bytów Lakeland, the Kashubia Lakeland, the Starogard Lakeland, and the Krajna Lakeland.
The geology of Tuchola Forest consists mainly of sandar glaciofluvial deposits of sand sediment, while the soil is predominantly of podzol type.
Climate The climate in the area is classified as Dfb climate, a variant of the hemiboreal subtype belonging to the humid continental climate type.
Phytogeography From the geobotanical point of view, the area encompasses several floristic landscape subregions forming the eponymous Tuchola Forest landscape region, classified as the only landscape region in the eponymous Tuchola Forest syntaxonomical subregion of the Sandar Forefields of Central Pomeranian Lake District syntaxonomical region located in the Pomeranian divide of the South-Baltic subprovince.
A smaller part of the forest is located in three out of five floristic landscape subregions forming the Świecie Plain landscape region, classified in the Chełmno-Dobrzyń syntaxonomical region belonging to the Mazovian subdivide of the Mazovian-Polesian divide in the Central European (Proper) subprovince.
Both floristic subprovinces are parts of the Central European floristic province in the Circumboreal Region of the Holarctic Kingdom.
Ecology and habitat
This predominantly coniferous forest is composed mainly of suboceanic (Leucobryo-Pinetum) and subcontinental (Peucedano-Pinetum) young Scots pine forest habitat types covering 64.5% of the area of land habitats, as well as of dry acidophilous Scots pine forest (Cladonio-Pinetum) covering 2.5% of the area,Siedliskowe podstawy hodowli lasu, and of marshy pine forest (Vaccinio-uliginosi-Pinetum). The Habitats Directive classifies the initial three habitat types jointly as the Central European lichen Scots pine forest habitat type, and the last one as belonging to bog woodlands habitat type, all belonging to the Forests of Temperate Europe group. The habitat classification of the European Nature Information System classifies the first type as belonging to subcontinental moss Pinus sylvestris forests, the second and the third type belong to subcontinental lichen Pinus sylvestris forests, while the fourth belongs to nemoral Pinus sylvestris mire forests.
Deciduous forest habitats cover minority of the forest area, mainly swamps, and include: Vaccinio-uliginosi-Betuletum-pubescentis birch bog forest, Ribeso-nigri-Alnetum alder carr, Fraxino-Alnetum riparian forest.
The occurrence of other phytocenoses such as for instance Betulo-Quercetum roboris, Molinio-Pinetum or Stellario-Carpinetum, is considered to be of fragmentary nature or in the form of deformed phytocenoses.
The forest belongs to the Baltic mixed forests ecoregion located in the European Continental Biogeographic Region, belonging to the temperate broadleaf and mixed forests biome of the Palearctic realm. The area is covered by the drainage basins of Brda and Wda, belonging to the Lower Vistula Basin, a part of the Vistula Basin emptying into the Baltic Sea, classified together with the rest of Central & Western Europe as temperate floodplain rivers and wetlands of the Palearctic realm.
Forestry For the purposes of forestry, Poland is divided into eight nature and forest lands, divided into nature and forest mesoregions, largely based on the borders of geomorphological mesoregions. The bulk of Tuchola Forest is located in the 3rd Greater Polish-Pomeramian Nature and Forest Land, where the forest covers the Tuchola Forest nature and forest mesoregion formed by merging the Tuchola Forest and the Charzykowy Plain geomorphological mesoregions, with the northernmost part of the merged unit being detached to form a separate Zaborski nature and forest mesoregion, also covered by the forest. Other nature and forest mesoregions of the 2nd Land which are partially covered by the forest include the Świecie Plain, the Brda River Valley and the Krajna 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.European forest classification - Categories and types for sustainable forest management reporting and policy
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). The nucleus of the Biosphere Reserve is protected by the Tuchola Forest National Park covering and of the 25 nature reserves lying within the buffer zone. The buffer zone includes Tuchola, Wda, Wdzydze and Zaborski Landscape Parks. There is also a transit zone which includes the town of Tuchola and surrounding districts. The core area of the Reserve covers , and the three zones together cover .Website of Tuchola Forest Biosphere Reserve
Ethnocultural region The term Tuchola Forest (), understood as an ethnocultural region and a historical land of Poland, carries a much narrower geographical sense than the area covered by the actual forest. In this meaning, the designation refers exclusively to the part of the forest which is inhabited by the Tuchola Borowians (or Borowians), a Polish ethnographic group, comprising the area located roughly north-east of Chojnice (Rytel, Gutowiec, Czersk, Łąg), south of Czarna Woda (Osieczna, Osówek), north-west of Świecie (Świekatowo, Lniano, Drzycim), north-east of Sępólno Krajeńskie (Wałdowo, Przepałkowo), stretching south to the suburbs of Bydgoszcz (Koronowo, Pruszcz), encompassing the entire Tuchola County (Tuchola, Raciąż, Bysław, Cekcyn, Śliwice, Legbąd, Lińsk, Gostycyn, Kęsowo, Żalno, Lubiewo). Borowians speak the Tuchola Forest dialect ( or ) of Polish belonging to the Greater Polish dialects, albeit under strong influence of Kashubian.
Prior to World War II, the western part of the region partially overlapped with the , or or , former ethnocultural region inhabited by a relatively secluded solid community of Catholic German settlers brought from the Prince-Bishopric of Osnabrück by the Teutonic Order State during its brief control of the area at the end the 14th century, who maintained their original culture (including clothing) and spoke Koschneiderisch, a distinct South-East-Pomeranian () dialect of Low German which preserved many features of Westphalian dialect of Middle Low German (spoken by the original pioneer founding settlers), itself heavily influenced by the Middle Dutch.
Other areas of the forest (including the National Park) are inhabited by neighbouring ethnographic groups: Kashubians (including Krubans, Borans and Zaborans), Kociewians (including Lasans and Piaskarze) - approximately 30% of the area, as well as Krajnians.
