One of the last remaining numerous indigenous populations are the Saami peoples whose traditional lands cover a huge swathe of northern Scandinavia. The Saami live in a very traditional way as reindeer herders, and knives and fieldcraft are an intrinsic part of their way of life.
My guess is that it's allemansratt or the tradition of 'freedom to roam' because the outdoors is so accessible the populous never urbanised like we have in the UK
Same reason as Canada and New Zealand feature - they have genuine wilderness, more-or-less similar climates, recognisable and related cultures. For those reasons I think we in the UK can learn a lot from them (and it'd be nice to think they could learn stuff from us as well).
Scientifically thinking there are more indigenous people in Fennoscandia other than Sámi people, Finns for example. However due of politics only the former ones have been dubbed as "indigenous".
Only part of the Sámi people have ever practiced reindeer herding and for example most of the Sámi now living in Finland adopted the reindeer herding at the same time as some Finns, that is during the 1100s and 1200s. Out of some 7000 Sámi living in Finland, only some of them own reindeers and even fewer ones earn their living from herding.
