Norway allocates 43 million kroner to combat invasive plant species

The Norwegian government has earmarked over 43 million kroner for nationwide nature restoration projects, including efforts to remove invasive plant species from Lågøya island in the Oslofjord, Dagbladet reports.

Climate and Environment Minister Andreas Bjelland Eriksen visited the island on Sunday to participate in the removal of invasive species such as gravbergknapp (pincushion flower) and rynkerose (rugosa rose). The initiative aims to restore the island’s natural ecosystem and protect endangered native species.

“This is a fantastic project,” Eriksen said. “They want to remove all invasive species here on Lågøya and restore the island’s natural state. The goal is to ensure red-listed species do not disappear.”

Lågøya, once a private holiday retreat for Circle K employees, was purchased by Sparebankstiftelsen DNB for public outdoor use. The island is now managed by the Norwegian Trekking Association (DNT) and the Oslofjord Outdoor Council, both working to eliminate invasive plants that threaten local biodiversity.

Invasive species outcompete native plants

The gravbergknapp, originating from the Caucasus, spreads rapidly and displaces native flora. Eriksen demonstrated its removal, digging up roots with a small fork to prevent regrowth. Similarly, rynkerose, introduced from the Himalayas in the 19th century, dominates shorelines and cultural landscapes with its deep roots, requiring heavy equipment for eradication.

“Restoring beaches and areas for public outdoor life holds great value,” Eriksen said. “We’re pleased to contribute financially to these efforts.”

Protecting rare species

The project also focuses on preserving endangered native plants like the dragehode (dragonhead), whose survival depends on the equally rare dragehodeglansbille (dragonhead beetle). These species exist only in a few locations around the Oslofjord and Randsfjorden.

“These plants and beetles are found in very few places worldwide,” said Kjetil Johannessen of the Oslofjord Outdoor Council. “Protecting them is crucial.”

Lågøya, now a popular rental destination, is nearly fully booked for the summer. Visitors will receive information about invasive species to prevent further spread.
