The total area of the park is 152.2 square kilometres (58.8 sq mi).It is located 62 km (39 mi) southeast of Białystok (Poland). It is known for the protection of the best preserved part of the Białowieża Forest, Europe's last temperate primaeval forest fragment that once stretched across the European Plain.
It is home to the world's largest population of European bison (Polish: żubr), the continent's heaviest land animals.2 The border between the two countries runs through the forest, the Belovezhskaya Pushcha National Park is adjacent on the Belarus side of the border.
An old-growth forest ? also termed primary forest, virgin forest, primeval forest, late seral forest, or (in Britain) ancient woodland ? is a forest that has attained great age without significant disturbance and thereby exhibits unique ecological features and might be classified as a climax community.1 Old-growth features include diverse tree-related structures that provide diverse wildlife habitat that increases the bio-diversity of the forested ecosystem. The concept of diverse tree structure includes multi-layered canopies and canopy gaps, greatly varying tree heights and diameters, and diverse tree species and classes and sizes of woody debris. Old-growth forests are economically valuable, and logging of these forests has been a point of contention between the logging industry and environmentalists.Źródło: https://en.wikipedia.org/wiki/Old-growth_forest.
