description Oostvaardersplassen Overview
Oostvaardersplassen is a 56-square-kilometer nature reserve in Flevoland, Netherlands, notable for developing unintentionally on a polder created after the Zuidelijk Flevoland drainage in 1968. Initially planned for industrial use, the area naturally developed into a wetland ecosystem that now hosts over 300 bird species. The reserve is managed using a rewilding approach, introducing large herbivores including Heck cattle, Konik horses, and red deer to maintain the landscape without human intervention. This controversial management strategy aims to recreate prehistoric ecosystem dynamics in this artificially created nature area.
help Oostvaardersplassen FAQ
How did Oostvaardersplassen form on reclaimed land?
The area emerged after Zuidelijk Flevoland was drained in 1968 and was initially intended for industrial development. Persistent wet conditions allowed reed beds, pools and grassland to develop before the land was designated for nature conservation.
Why were Konik horses and Heck cattle introduced there?
Managers introduced large grazers to imitate ecological roles once performed by wild horses and aurochs-like cattle. Red deer later became another major grazer in the reserve's open grassland system.
Why has Oostvaardersplassen been controversial?
The large herbivores live within a bounded reserve without a complete set of natural predators or unrestricted migration routes. Severe winters and animal deaths therefore triggered disputes over feeding, population control and whether the site represented genuine rewilding.
Can visitors see the Oostvaardersplassen wildlife?
Yes, the Flevoland reserve has observation points and visitor facilities for viewing birds and the open landscape. Access to sensitive interior areas can be restricted, so most visitors experience the roughly 56-square-kilometer reserve from designated routes and hides.
