Description

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 2020, where alien vascular plants were surveyed in field by experienced botanists (5 hour upper time limit) and insects were sampled by malaise traps during 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).

Sampling Description

Study Extent

South-east Norway August - September 2020

Sampling

Experienced botanists surveyed alien plants at each locality. 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 by experienced botanists identifying species in field. Insects sampled in malaise traps, Coleoptera and Lepidoptera identified by taxonomists.
