Here is an interesting article that has quantified and verified that Traditional Ecological Knowledge is being lost in First Nations communities.  The researcher tested Elders on their knowledge about an indigenous bird, and then tested young adults on their knowledge of the same bird.  Elders far outscored young adults with respect to knowledge that should be common to this cultural group.

These results spurred the Elders, with the help of the researcher, to create a Cree curriculum for the TEK that should be passed down to future generations.

This is one of the better articles about TEK that I have read for a few reasons.  It acts on results with the formation of a curriculum that is driven by the Elders, it links TEK with culture, it considers the historical events that have contributed to the degredation of TEK, and it points out the global significance to people beyond the culture that hold the TEK.
