Tidlig oppdagelse og varsling av fremmede arter 2019

Study Extent

South-east Norway August - September 2019

Sampling

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

1. Plants registered along transects by experienced botanists identifying species in field. Insects sampled in malaise traps, Coleoptera and Lepidoptera identified by taxonomists.
