Distribution of Barnacle GeeseBranta leucopsisin Relation to Food Resources, Distance to Roosts, and the Location of Refuges

摘要: We used GPS satellite tracking data and field measurements of vegetation to investigate the effect food resources, distance roosts, location refuges on distribution Barnacle Geese Branta leucopsis in northern part The Netherlands. To deal with spatial dependence among data, a lag model was used. A significant quadratic found between sward height goose distribution, indicating that geese prefer patches intermediate heights. manipulation can therefore be attract thus reduce grazing agricultural land. No relationship grass nitrogen content intensity, do not distinguish areas based content. higher intensity observed located within 2 km from roosts. eight tracked spent 80% their foraging time refuges, demonstrating importance refuge system.
