Vlieland is one of four areas in NIOO-AnE's long-term monitoring research on great tits and other bird species that started in 1955. It consists of several smaller forest areas, which together cover about 250 ha of mainly conifers and oak on poor sandy soil. As Vlieland is an island in the Wadden Sea, the area stands completely on its own. Important population questions in NIOO's long term research are/were studied here.

The foundation 'Land van Ons' has obtained a peat meadow area near Leiden to increase biodiversity in this intensively used agricultural area. The goal is not to recreate nature, but to develop sustainable agricultural use of this land with the goal of increasing biodiversity in the area and developing management strategies that optimise its ecological, economic and recreational value.

The Long-Term Socio-Ecological research platform Dutch Wadden Sea area is a large coastal area bordering the north of the Netherlands.

Two of the most pervasive human impacts on ecosystems are alteration of global nutrient budgets and changes in the abundance and identity of consumers. In spite of the global impacts of these human activities, there have been no globally coordinated experiments to quantify the general impacts on ecological systems. The Nutrient Network (NutNet) is a grassroots, global research effort to address these questions within a coordinated research network comprised of more than 130 grassland sites worldwide.
