Preliminary Norwegian Assessment: Indian Silverbill Did Not Proceed to Full Risk Assessment

Indian silverbill (Euodice malabarica) did not proceed to a full ecological risk assessment for mainland Norway in Artsdatabanken’s preliminary 2026 alien-species assessment. The assessment was published on 11 June as part of the public-review process for Fremmedartslista 2029.

Why the Species Did Not Proceed to Full Risk Assessment

The species was first evaluated through horizon screening, a screening step used to identify potential “doorstep species” that warrant a full ecological risk assessment. In Artsdatabanken’s framework, a doorstep species is a non-native species that does not currently reproduce independently outdoors in Norway but could do so within the next 50 years, or could cause relevant ecological effects even without long-term establishment.

Indian silverbill was placed in establishment category 1: after one introduction, the screening expects no occupied 2 × 2 km grid cells to remain ten years later because the introduced population would have died out. Its negative ecological-effect score was also category 1, meaning substantial negative ecological effects were assessed as absent in the screening. With scores of 1 on both axes, the species did not cross the threshold that would trigger a full risk assessment.

With that combination, the species was classified as NR — not risk-assessed — rather than taken forward as a doorstep species for mainland Norway and surrounding marine areas. NR is therefore a process outcome, not a low-risk category: the species did not receive a full ecological risk classification because it failed to meet the screening threshold. Artsdatabanken states that the outcome is the same as in Fremmedartslista 2023.

The assessment was one of the preliminary bird evaluations opened for public input from 11 June to 10 August 2026. Artsdatabanken emphasized that the results were provisional and could change after information submitted during the review period was assessed.
