Abstract
Two pilot studies were done on the salt marsh of Schiermonnikoog. Pilot study 1: the abundance and diversity of the seeds in creeks was determined. Floating seeds were caught with nets in two creeks at the high salt marsh. a. The occurrence of seed transportation in the creeks on the salt marsh was ascertained. But nothing could be said on direction of transport. b. There was no correlation between the floating capacity of the seeds and the caught seeds. This indicates a local dispersal. Pilot study 2: the movement of seeds over salt marsh vegetation was looked at on the low salt marsh. Several potential factors on the transportation of the seeds were measured. The distance to the creek, the distance to the sea, the elevation and the height of the water level, using a known number of marked seeds on seed traps. a. The effect of the height of the water level on the dispersal of the seeds was stronger than the effects of the distance to the creek and sea or the elevation of the location. During spring tide more seeds were transported than during neap tide. b. Natural dispersed seeds on the seed traps were mostly of plants in the local vegetation (within 2 m).
