Zanderij Crailoo 

This site is a small nature reserve between the towns of Bussum and Hilversum, in the central Netherlands. It lies between a forest and a heathland, which are connected by an ecoduct. The soil consists of a layer of sand deposited by cold polar winds during the last ice age. A few years ago, the area was restored and several ponds were excavated.

Today it is a hotspot for many testate amoebae, including the freshwater foraminifer Lacogromia cassipara.

My favorite samples locations are:

B – a small ditch;
C – a pond.
