I'm not sure are you talking about Lapland or Fennoscandia.

The threatened population is the one in Fennoscandia. This population decreased drastically around the start of the 20th century.

Lapland is a region in northern Fennoscandia, largely within the Arctic Circle. It stretches across Norway, Sweden, Finland and Russia.

Lapland is the region of Northern Fennoscandia and includes part of Russia. The area is also known as Sápmi, and includes many cities such as Alta, Boden, Sodankyla, and Murmansk.
