Status and distribution in Luxembourg

First sightings of the Canada goose were reported by Eugène Conrad on 19th April 1980 in the area of Stolzembourg, municipality of Putscheid (Konter et al. 2009). The first documented breeding in Luxembourg dates from 2002 from the nature conservation reserve Cornely’s Millen, near Troisvierges in the far north of the country (Bastian 2016: 6). The first successful breeding attempt was documented in 2002. Meanwhile the species breeds regularly in Luxembourg with some 10 to 15 breeding couples, especially on the Moselle river and in the Oesling area (Lorgé & Melchior 2015). Today the Canada goose is less widespread in Luxembourg than the Egyptian goose. A recent survey estimates the actual breeding population of the Canada goose to a total of 18 breeding couples (Bastian 2016: 13). Problems caused by Canada geese were reported in 2016 by several local authorities to the Department of Environment of MDDI, concerning several playgrounds, promenades and open air swimming pools in the Moselle area, and also from problems in a vineyard in the Schengen area.

Canada geese most often breed along small meso- to eutrophic ponds near open habitats with short grass. They are especially common in man-made habitats (parks, urban and agricultural areas) but are also known to colonise natural wetlands and coastal areas. The Canada goose is primarily a grazer and feeds mainly on grasses and aquatic plants. The species often exhibits direct aggression to other bird species through strong territorial behavior. High goose densities damage wetland habitats by overgrazing, fouling and trampling (Source: http://ias.biodiversity.be/species/show/147).

Risk assessment

ISEIA protocol

ISEIA Protocol: B3 (3+3+2+2) = Watch List. Assessement update on 15 May 2018 by Patrick Lorgé, Christian Ries & Manou Pfeiffenscheider. First assessment: ISEIA protocol: A1 (3+3+3+3) = Black List (Ries et al. 2014: 199). The adverse impacts on native species and ecosystem functions were overestimated by the first assessment.
