Abstract english

Regular goose counts have been undertaken in Sweden
since 1977/78 as a part of the International Goose Counts
organised by Wetlands International. The main counts are
undertaken in October and November, covering all sites of
importance for Bean Goose Anser fabalis and in January
when all sites are covered. September counts of Greylag
Goose Anser anser will be published separately. In October,
the major part of the World population of the Taiga
Bean Goose Anser fabalis fabalis is found in Sweden. The
population increased from about 20,000 in 1960 to 80,000
in 1989, after that it has decreased to about 50,000. During
the study period Bean Goose numbers decreased markedly
in the southernmost part of Sweden, whereas numbers
increased at sites further north in southern Sweden. The
species also established new important staging areas. This
change in distribution was probably related to differences
in hunting pressure between different regions and to changes
in agriculture. Staging populations of White-fronted Goose
Anser albifrons also increased during the period reflecting
changes in the much bigger population south of the Baltic.
Marked increase in numbers and a spread to new sites were
also noted among staging Greylag Geese, Canada Geese
Branta canadensis and Barnacle Geese Branta leucopsis
reflecting increased breeding populations in south Sweden.
