De Biesbosch is a crucial habitat for numerous species, including the European beaver, reintroduced in 1988 and now thriving. The park is home to diverse bird species such as white-tailed eagles, osprey, and various waterfowl. The waters support significant fish populations, including pike, perch, and eel. Notable mammals include roe deer, root voles, and several bat species. The area serves as an important stopover for migratory birds.
The park's vegetation is remarkably diverse, featuring extensive reed beds, willow forests, and marshland plants. Notable species include common reed, bulrush, and various willow species that form natural flood forests. The area also hosts rare aquatic plants and numerous species of mosses and lichens. Seasonal variations bring spectacular displays of wildflowers in spring and summer, including yellow iris and purple loosestrife.
The landscape of De Biesbosch is characterized by a complex network of creeks, islands, and mudflats formed through centuries of tidal action and sediment deposition. The area consists primarily of alluvial soils, with layers of clay and peat. Following the partial closure of the Haringvliet in 1970, the tidal range decreased from 2 meters to about 30 centimeters, resulting in significant ecological changes and new land formation patterns.
De Biesbosch ('forest of rushes') was dramatically shaped by the St. Elizabeth's Flood of 1421, which transformed agricultural land into a freshwater tidal area. Throughout history, the region was vital for reed cutting, fishing, and basket weaving. During World War II, it served as a crucial hiding place for resistance fighters. The completion of the Delta Works in the 1970s significantly altered the area's tidal nature, leading to its current status as one of Western Europe's most important freshwater tidal wetlands.
Key attractions include the extensive network of waterways perfect for kayaking and boating, several visitor centers offering educational exhibits and boat tours, and numerous hiking and cycling trails. The Biesbosch Museum Island provides historical context and environmental education. The park's unique freshwater tidal system, though diminished, remains one of the few examples in Europe, making it a significant site for ecological study and nature observation.
De Biesbosch experiences a temperate maritime climate typical of the Netherlands, with mild winters and cool summers. Average temperatures range from 2°C (35°F) in winter to 17°C (63°F) in summer. The area receives significant rainfall throughout the year, with an annual average of 800mm. Weather conditions can change rapidly due to the park's location near the North Sea, making it advisable for visitors to bring waterproof clothing regardless of season.
