Nuolja, also known as Njulla, is a field research site in Sweden that stretches across Mt. Njulla.[1] With the mountain to the east, the village of Abisko to the south, and bordering Lake Torneträsk, this is a varied-habitat field site.[1] Mountain birch forests are one of the main appeals of this research site.[1]
The name "Nuolja" may also refer specifically to a 12km hiking trail on Mt. Njulla, Sweden.[2]
