“The lupine is a problem because it outcompetes the shorter meadow species on the roadside,” says Linnéa Hedman Söderström, environmental specialist at the Swedish Transport Administration, in a press release.
Road sections with particularly high species richness have been selected. Among other things, red-listed species such as night violet, field gentiana and hay fever grow there.
The lupine plants will be uprooted or dug up by the roots, and then transported away for incineration. Staff then need to return several times in order for the lupins to disappear for good.
