The number of resident birds in the natural area Buurserzand in the province Overijssel, the Netherlands, has strongly increased in the past years. The number of different species as well as individual breeding pairs has seen an increase.
According to the organization Natuurmonumenten, the increase in birds here is in large part due to the successful management of the area. In several parts of Buurserzand more water has become available for wildlife. Approximately 30 hectares of the former private holding Rietschot were added to the Buurserzand protected area in 2005 and since then the number of waterfowl species in the area has increased from six to ten. The number of individual birds has increased from 26 to 88.
