Native Knowledge: What Ecologists Are Learning from Indigenous People
From Alaska to Australia, scientists are turning to the knowledge of traditional people for a deeper understanding of the natural world. What they are learning is helping them discover more about everything from melting Arctic ice, to protecting fish stocks, to controlling wildfires.

Excerpt: "The #Skolt #Sami people of #Finland, for example, participated in a study that was published in the journal Science last year, which adopted indicators of #EnvironmentalChanges based on #TEK. The Sami have seen and documented a decline in salmon in the #NäätämöRiver, for instance. Now, based on their knowledge, they are adapting – reducing the number of seine nets they use to catch fish, restoring spawning sites, and also taking more pike, which prey on young salmon, as part of their catch. The project is part of a co-management process between the Sami and the government of Finland.
"The project has also gathered information from the Sami about insects, which are temperature dependent and provide an important indicator of a changing Arctic. The Sami have witnessed dramatic changes in the range of insects that are making their way north. The scarbaeid beetle, for example, was documented by Sami people as the invader arrived in the forests of Finland and Norway, far north of its customary range. It has also become part of the Sami oral history.
"It’s not only in the Arctic. Around the world there are efforts to make use of traditional wisdom to gain a better and deeper understanding of the planet – and there is sometimes a lot at stake."

"Climate change and human activity have impacts that ripple through all ecosystems. Their negative effects can lead to population imbalances across these various #ecosystems. While populations of many species are declining because they are unable to survive the rapid #EnvironmentalChanges, this is often not the case for venomous aquatic life like #SeaUrchins and jellyfish. In fact, these populations are increasing across the globe, with damaging effects on other living #AquaticOrganisms and human activity."
