Piska Forest

Puszcza Piska Forest or the Pisz Forest (German: Johannisburger Heide) is the largest forest complex of the Masuria region in northern Poland, adjacent to the Masurian Landscape Park, and the Masurian Lowlands. Formerly known as the Jańsborska wilderness, Puszcza Piska bears the name of the Pisa river bordering the Forest along its west bank.

The Pisz Forest consists of a unique combination of coniferous trees, lakes and rivers. Its total area is c.100,000 ha. It covers the counties of Mikołajki, Mrągowo, Piecki, Sorkwity, Biskupiec, Biała Piska, Orzysz, Pisz, Ruciane-Nida, Dźwierzuty, Rozogi, Szczytno, Świętajno, Kolno, Turośl and Łyse. Within its borders are a number of lakes, designated as nature reserves. Among them: Bełdany, Nidzkie, Jegocin, Warnołty nature reserve, Mokre, and the largest lake in Poland called Śniardwy. Two principal rivers flow through the area – Krutynia and Pisa, as well as many smaller tributaries and streams.

The southern part of the forest grows on sands and lowland bogs. The soil is being drained by the Narew tributaries, including Pisa and Szkwa, as well as many lakes. The northern part of the complex borders on Masurian Lake District known in Polish as Kraina Wielkich Jezior. The Piska Forest consists of pine and spruce groves with the mixture of birch, aspen, maple, alder and oak growing on sandy soil mainly at the southern end of the forest. The best known among the local trees is the "Masurian pine" covering eastern edges of the Mokre lake. It reaches the height of 40 m and the age of 200 years.
