Test of a survey system for early detection of new alien species in early establishment in Norwegian nature. System tested for 20 sites in South-east Norway in 2019. Includes data from field surveys of vascular plants and from insects sampled with malaise traps.Purpose
The data set contains plant species registered at 20 localities in the follow-up study for the project “Tidlig oppdagelse og varsling av nye fremmede arter”.Sampling Description
Study Extent
South-east Norway August - September 2019Sampling
Two experienced botanists surveyed plants at each locality, focusing on plants they considered to be non-native, but also registering native species. They performed the surveys independently, each botanist surveying 15 sites with an overlap of 10 sites (i.e. 20 sites in total). Species were identified in field. Each survey was restricted to maximum 5 hours. Insects were sampled with malaise traps, one trap per locality. The trap was operated during July and August and emptied four times through the period. Lepidoptera and Coleoptera were sorted from the samples and identified by taxonomic experts.Method steps
- Plants registered along transects by experienced botanists identifying species in field. Insects sampled in malaise traps, Coleoptera and Lepidoptera identified by taxonomists.
