In her article 鈥淭he Pressure of Conservation: How the Imaginry of 鈥榃ild`Nature Was Formed and How to Rid Ourselves of it鈥濃, Sabine Schulz Blank makes a compelling argument on how our conception of 鈥渨ild鈥 nature derives from a misinformed understanding of the nature - culture relationship. She uses examples from the Amazon jungle where historical ecology has shown that ancient agrarian societies has in fact improved biodiversity and made the landscapes more resilient to environmental stress. Like their cultivation of the soil, creating an especially fertile type of soil termed 鈥淎mazonian Dark Earths鈥 (ADE/ terra preta).
In a similar manner one can find examples of cultivation of water bodies that has improved their ecological conditions. In many places across Norway some of the best and riches mountain waters are a result of human cultivation. For years people have been introducing fry to mountain waters and river streams to enrich or introduce fish population. The creation of fish ladders and passes have been, and still is an important part of this cultivation.
Though there are still rivers where fish ladders are constructed of natural rocks and wood, most modern fish ladders are made of concrete and placed in areas where the water has been disrupted by human activity. So even if the disruption was man-made to begin with, these types of constructions aid and enhance the biodiversity of the water bodies where they subside. Maybe this design in nature is not 鈥渦nnatural鈥, maybe we should look a little bit closer and ask ourselves what 鈥渨ild nature鈥 (as Schultz Blank said) really is.
