The norwegian redlist catalogues plants that are threatened in Norway, while the blacklist
concerns imported plants which spread so vigorously that they become a threat to our native flora. In a circular bed beside the Victoria greenhouse we grow examples from both lists, both the ones we wish to protect and the ones we want to keep in check.
The Botanical Garden is strongly engaged in the efforts to protect and conserve threatened species. We do extensive outreach to inform the public, we have a seed bank for vulnerable and threatened species, and we propagate and maintain populations of many threatened species native to our local area. We are also involved in eradicating the most problematic of the blacklisted species, particularly on the islands of the inner Oslo fjord.
