Fire is such a hot topic these days - pun intended! Yet we used to have a lot more fire across the landscape than we do today…so whats going on? Fires are a naturally occurring part of a forest ecosystem, and are generally classified as either low-intensity burns (LIBs) or high-intensity burns (HIBs), both of which have different causes and impacts based on different forest types and factors. Since colonization of North America by western societies, a combination of fire suppression and large scale land alteration through logging has left our forests in a highly vulnerable state all across the continent that makes them more susceptible to large-scale HIBs, which has big picture issues relative to both volume and frequency. Speaking to volume, its estimated that roughly 85% of native forests here in North America has been lost, logged or modified to the equivalent of a HIB, which is an insanely large number, and much of this has been done in a manner that reduces the ecological function of these forests and actually contributes to large scale HIB’s that we see more and more often each summer. In the last 400 years of western colonization roughly 85% of native forests have been lost to the equivalent of being burnt to the ground in a HIB (in some places 4x over), which historically only ever happened in much smaller scale fires every 1000 - 2000 years if at all, yet we’re calling this all natural and sustainable…sounds more like the apocalypse to me 😬 So instead of trying to replicate these HIBs in our clearcut logging practices, we need to allow our forest ecosystems to mature in a healthier manner over a longer period of time, and we need to spend a lot of energy properly thinning and restoring the ecological function of the billions of hectares we’ve mismanaged thus far. Through prescribed burns and by replicating LIBs we can not only create a more humble, sustainable industry and jobs, but we can improve the ecological health and functions of the lands we live amongst for a better future in this uncertain era of climate change. #climate #fire #climatechange #wildfire #forest #climateemergency #fossilfuels #logging #whoa #bc #canada #oldgrowth #edu
