The park supports a diverse array of wildlife typical of Finnish boreal ecosystems. Large mammals include moose, brown bears, and wolves, though the latter two are rarely seen. The wetlands provide crucial habitat for numerous bird species, making it an important area for bird watching. Notable species include the common crane, wood sandpiper, and various birds of prey. The mires are breeding grounds for several northern bird species like the yellow wagtail and meadow pipit. The park's waters host beaver populations, while its old-growth forests provide habitat for various woodpeckers and the Siberian flying squirrel.
Patvinsuo's vegetation is characterized by a mosaic of mire plants and boreal forest species. The mires host specialized plants such as cloudberry, cranberry, and various sedges. Carnivorous plants like sundew and butterwort thrive in the bog environments. The forest areas feature typical boreal species including Scots pine, Norway spruce, and silver birch, with an understory rich in lingonberries and blueberries. The park is also home to several rare and threatened plant species adapted to mire ecosystems. Old-growth forests contain significant populations of various lichens and fungi, including several endangered species dependent on dead wood.
The park's landscape was primarily shaped by the last ice age, which ended approximately 10,000 years ago. The retreating glaciers left behind a diverse terrain of eskers, kettle holes, and glacial deposits. The area's bedrock consists mainly of ancient granite and gneiss, typical of the Fennoscandian Shield. The most distinctive geological features are the extensive mire systems, which have developed over thousands of years through natural paludification processes. The park contains various mire types, from nutrient-rich fens to nutrient-poor bogs, formed by different hydrological conditions and underlying soil compositions.
Patvinsuo National Park was established in 1982 to protect valuable mire ecosystems and old-growth forests characteristic of eastern Finland. The area has a rich cultural history dating back to the Stone Age, with evidence of early hunting and gathering communities. During the 19th and early 20th centuries, the region was significant for slash-and-burn agriculture and forestry. Traditional activities like berry picking and hunting have been practiced here for generations. The park's establishment marked a crucial shift in Finnish conservation efforts, recognizing the importance of preserving large, intact mire ecosystems. Today, it serves as an important research area for studying natural mire development and forest ecology.
The park's most remarkable feature is the Suomunjärvi Lake, surrounded by extensive mire systems and old-growth forests. The Suomunjoki River, which flows through the park, offers excellent canoeing opportunities. The park contains several marked hiking trails, including the popular 15-kilometer Suomunkierto Trail. Notable viewpoints include the Teretinniemi observation tower, offering panoramic views over the mire landscape. The park also features several primitive camping sites and three wilderness huts available for public use. A unique aspect is the coexistence of different mire types, from string bogs to aapa mires, making it an excellent location for studying northern wetland ecosystems.
Patvinsuo National Park experiences a typical North Karelian climate with distinct seasonal variations. Winters are long and cold, with temperatures often dropping below -20°C and reliable snow cover from November to April. Summers are relatively short but mild, with average temperatures between 15-20°C and occasional peaks reaching 25°C. The park receives approximately 600mm of annual precipitation, with rainfall most common in late summer and autumn. Spring thaw typically occurs in April, while autumn colors peak in September. Due to its northern location, the park experiences significant variations in daylight hours, with nearly continuous daylight in midsummer and brief daylight periods in midwinter.
