This site is a small nature reserve between the towns of Bussum and Hilversum, in the central area of the Netherlands. It lays between a forest and heath, both areas connected by an ecoduct. The soil is a layer of sand, deposed by cold polar winds during the last ice age. Some years ago this area has been reconstructed and some ponds have been digged out.
My samples come from three locations:
A - a large pond;
B - a small ditch;
C - a pond.
