Historically, the borderland regions of Mazovia and Lithuania, the area retains much of its cultural diversity today.Cultural and linguistic environment
The basin of the Biebrza River is inhabited not only by hundreds of rare and endangered sorts of birds, but also by people representing diverse cultures, languages, and religions. Although most of the population of the region speaks standard Polish, some people in the upper river basin speak a local dialect of Belarusian. The people there belong to the Orthodox or Roman Catholic church. On the north bank of the upper Biebrza there are also a few villages where so-called "old believers" live, who speak an archaic dialect of Russian. Some of these communities have preserved much of their traditional culture in spite of long-lasting communist government policies aimed at assimilation of non-Polish cultural and linguistic minorities.
