Mow or cut reedbeds
A site comparison study in two wetland sites in Vejlerne, a wetland in North Jutland, Denmark (Kristiansen 1998), found that the highest densities of greylag geese Anser anser nests were found in reedbeds that were cut between five and eleven or five and 12 years before (3.1-3.4 nests/ha). No nests were found in beds cut that year and very few (and only in one site) in beds cut less than three years (fewer than 0.7 nests/ha) or more than eleven years before. The authors speculate that geese need an intermediate density of reed stems to nest effectively.
