A collection of biodiversity researchers from across Europe came together in Brussels for a unique kind of meeting last week. We were connected by two common threads: first, we are all supported by BiodivERsA, a large network of European biodiversity research projects funded by the European Union’s Horizon 2020 program. And second, most importantly, we are all interested in connecting our biodiversity research with citizen science in one form or another.

In this series, we’ve already learnt about the impacts of alien trees and garden plants in Norway, but others are invading too, including some that are easier to overlook. And some of them can not only out-compete native species, but also pose health problems for humans. In today’s guest post by Vanessa Bieker, we look at Ambrosia artemisiifolia (common ragweed), which produces highly allergenic pollen and is one of the main causes of hay fever.

Garden plants have a long tradition in Norway; from being used as medicine and food in the gardens of Catholic monasteries in the Middle Ages to today’s exotic ornamental plants. But this tradition also represents several centuries of unmonitored introductions of alien species, and it has left its mark in Norwegian nature.

In 2004, there were more than 873 alien species of plant in Norway, the majority of which are simple garden species. Next week, Museum PhD Candidate Malene Nygård will take us through some of the introduction pathways and problems that garden plants present. But now, we look at one of Norway’s most ubiquitous plant invaders, the Garden Lupin.
