Invasive alien species
By combating invasive alien species, the Finnish Transport Infrastructure Agency is enhancing biodiversity in transport infrastructure environments.
Efforts to eradicate giant hogweed in road and railway areas have continued for many years. The measures to combat rugosa rose and garden lupine, which are both widespread in Finland, are prioritised in accordance with the management plan for alien species. Alien species that have been designated or identified as invasive are not planted in transport infrastructure environments.
Timing of vegetation clearing on roadsides can impact the spread of invasive alien species. Flowering lupines are among the plants mowed in this process, which helps to ensure that their seeds are not carried to new locations.
Eradicating invasive alien species, such as lupine or rugosa rose, in areas close to roads and railways is not an everyman’s right and may not be done without a permit. For example, you are not allowed to trespass on motorways or other limited-access roads, and entering railway areas to do vegetation clearing is also prohibited.
If you are planning to eradicate vegetation in these areas, you should first contact Traffic Customer Service for more information on the conditions that apply. Go to Traffic Customer Service.
Under the government decree that entered into force in summer 2019, landowners must take measures to combat invasive alien species such as rugosa rose and garden lupine. The three-year transitional period for the ban on breeding rugosa rose set in the decree will end on 1 June 2022.
Rugosa rose is an alien species in Finland and a threat to biodiversity. Even if rugosa rose did not cause any harm in its growth location, its rose hips and seeds can be carried by migratory birds or flowing water over long distances.
In the past, rugosa rose was extensively planted in such places as roadsides because it can tolerate salty road environments and difficult growth conditions.
