Eilandspolder

Eilandspolder is a wetland polder of about 1,400 hectares in Noord-Holland comprising grasslands, natural lakes, and marsh vegetation. The area supports diverse bird populations and small mammals across its landscape of water and grassland.

Until the 10th century, the area formed part of a connected peat landscape before major storms in the 12th and 13th centuries reshaped it dramatically. These flood events created the water bodies and molded the polder landscape we see today.

The eastern section shows long, regularly arranged field parcels shaped by generations of farming. These patterns reflect traditional land management practices that still define how the landscape looks today.

The area maintains strict environmental protection under Natura 2000 and the Birds Directive, so visitors must stick to designated paths. Early morning and evening visits are best for observing wildlife without disturbing the resident birds.

The water contains specific salt concentrations between 150 and 350 milligrams per liter, supporting specialized aquatic plants and animals. This slightly elevated salinity creates a unique environment that only certain species can inhabit.
