| | Drawa National Park, NW Poland |
 | | Post-glacial deposits (mainly sands) building the bedding of the Park are rich in calcium carbonate, what is reflected in the geochemistry of the landscape and also in its flora (calciphil species, as twig rush Cladium mariscus, calciphil plant associations in the lakes and on the swamps). |
 | | - The forests of the Drawa NP are at the greater part of the area strongly transformed by the 19th and 20th century forestry. |
 | | - On the area of the Drawa NP some spontanic processes of vegetation dynamics may be observed - primary succession (transforming of lakes into swamps), secondary succesion (afforestration of abandoned meadows and fields), regeneration of forests relieved from the forestry pressure, fluctuation in the quasi-natural forest phytocoenosis. |
