Preliminary Norwegian Assessment Keeps Egyptian Goose at Very High Ecological Risk

Niland (Alopochen aegyptiaca)
Conservation · Threats

A preliminary Norwegian assessment published in June 2026 continues to classify Egyptian goose (Alopochen aegyptiaca) as an alien species with very high ecological risk in mainland Norway. The assessment was prepared by Artsdatabanken’s expert committee for birds as part of the work towards Fremmedartslista 2029 and was published for public review on 11 June 2026.

Very high risk combines invasion potential with ecological effect

The species is placed in the SE category, very high risk, with uncertainty extending down to HI, high risk. Fremmedartslista combines two axes: invasion potential, which describes the species’ ability to establish, persist and spread, and negative ecological effect on native nature. Egyptian goose receives the highest invasion-potential score, 4, with uncertainty to a lower score, while ecological effect is scored 3, described by the assessment as moderate. The overall SE category therefore reflects the combination of strong future establishment potential and ecological effects rather than evidence that severe damage is already occurring in Norway.

Egyptian goose is native to Africa but has established free-ranging populations in several European countries after introductions as an ornamental bird. The Norwegian assessment notes established populations in countries including Denmark, Germany and the Netherlands. Birds recorded in Norway are considered to originate from these established populations abroad.

Egyptian goose is still a doorstep species in Norway

The expert committee reports that Egyptian goose was first recorded in Norway in 2002. Up to and including 2024, 20 observations involving 23 individuals had been documented. No breeding has been confirmed in Norway, and the committee found no increasing trend in observations of pairs. Artsdatabanken therefore treats it as a doorstep species: it occurs in Norwegian nature but has not yet established a self-reproducing outdoor population, while future establishment is considered plausible.

Despite the currently low number of Norwegian records, the assessment gives the species a high invasion-potential score because of its expansion in neighbouring parts of Europe and the possibility of future establishment. The experts suggest that climate may currently limit the species in Norway, but that this could change with warming. Based on developments in neighbouring countries, they consider it possible that Egyptian goose could establish as a breeding bird in southern Norway within a 50-year perspective, where many wetlands could provide suitable breeding habitat.

Competition drives the ecological-effect score

The ecological-effect score is based mainly on competition. Egyptian geese can behave dominantly and aggressively towards other birds during breeding, potentially displacing ducks, geese, coots and birds of prey from feeding areas or nesting sites. The assessment specifically lists competition for space involving common shelduck (Tadorna tadorna) and mallard (Anas platyrhynchos). The experts describe the documented effects as generally low to moderate even in areas with high Egyptian goose densities, but note uncertainty in the evidence.

The 2026 assessment does not represent a new increase in risk category: Egyptian goose was also classified as SE in Norway’s 2023 assessment. It is a preliminary assessment released for public review, not a final Fremmedartslista 2029 result. Artsdatabanken states that both the content and the outcome can change after submitted evidence has been reviewed; a consolidated updated list for all groups is planned for 2029.
