Bert Bospad – Westbroekse Zodden

This site is a large nature reserve, called Westbroekse Zodden, located southwest of the town of Hilversum, in the central area of the Netherlands. It consists of peatland fen-meadows bordered by brook forest. Originally this area was one large fresh water marsh, but since medieval times peat has been mined here and this activity shaped the landscape.

My samples came from two locations:
T – A so called “trilveen”, a quaking or vibrating bog; this is a peat bog floating over water-saturated ground, so that is shakes or trembles when walked on. The wet part is covered with Sphagnum, the drier part with Polytrichum.
L – Peatland, with some very shallow water.
