Effects of Wildfowl Distribution and Behaviour
The potential of wildfowl to consume a large proportion of the
available Zostera biomass has been noted elsewhere. The feeding patterns of
wildfowl can be heavily modified by shooting disturbance (Madsen, 1988), and this may
therefore have an indirect effect on the exposure of Zostera beds to grazing
pressure. Recent experiments in Denmark (Madsen, 1988, 1995) showed that reducing shooting
disturbance could significantly increase the numbers of wildfowl using a site and grazing
on the Zostera resources.
