Tidlig oppdagelse og varsling av fremmede arter 2021

Survey of plants and insects for early detection of new alien species in early establishment in Norwegian nature. 25 sites (250 x 250 m) in South-east Norway were surveyed in 2021, where alien vascular plants were surveyed in field by experienced botanists (5 hour upper time limit) and insects were sampled by malaise traps during May, June, July and August. Coleoptera and Lepidoptera were identified morphologically from 10 samples (all 100 samples from the malaise traps were analysed by DNA-metabarcoding, data not presented here but stored in a separate database at NINA).
