Abstract
    The effects of horses, rabbits and coypu on plant succession were studied in five different vegetation types in the Camargue (southern France) over three years. The horses had a very marked effect on a Scirpus maritimus-Phragmites marsh, considerably reducing the amount of the two main species. In the other sites, the effects were less drastic. In the two grassland areas, they reduced the vegetation height in the third year, and there was also a change in species composition at one site which was used more intensively than the other. In a second marsh site, they caused a reduction in the amount of the dominant grass (Aeluropus litoralis), while they controlled the quantity of two of the principal species of a dwarf serub area (Halimione portulacoides and Puccinellia distans). The effects of the rabbits and coypu, on the other hand, were not very pronounced. Very high rainfall during the experiment was an important constraint on succession. These are preliminary results from a long term study of vegetation dynamics in the area.
