But the land is markedly different than just a few generations ago. Berries and grasses and other parts of the ecosystem rely on fire to thrive, to regenerate and enrich the soil. In particular for bighorn sheep, fires would take down some trees and allow more light to hit the forest floor, leading to the open grassy areas they like. But colonialism brought fire suppression, which led to a build-up of fuel on the forest floor. This meant more destructive and unpredictable fires and less ideal conditions for species that First Nations stewarded with controlled cultural burns for years. B.C. was the first province to ban cultural burns in 1874, meaning that knowledge wasn’t passed down the same way it used to be.
