Fire in Nature - A Fire Activist's Guide is about the role of fire in nature's ecosystems and the damage being done to global ecosystems, property, and loss of life, by a culture of fire exclusion and fire suppression. In this book the author begins with the important role that fire has played in shaping the evolution of our forests, savannas, and grasslands, going back hundreds of millions of years. Next he outlines the important role that man himself has played as he evolved out of fire sculpted grasslands of Africa to become a global indigenous native landscape artist out of survival necessity. After these native land managers were almost wiped out by disease and conflict during the period of the European conquests, fuel accumulations began to build due to the loss of these native managers in light fire ecosystems, leading to more and more catastrophic fire. In turn, in a vicious cycle, misguided European land managers began to fearfully exclude and suppress fires in light fire ecosystems. This misguided policy has led to the widespread global destruction of tens of millions of acres every year by catastrophic wildfire caused by these ever growing fuel accumulations not being removed by light restorative fires that maintain healthy light fire ecosystems. Lastly the author recounts his own immersion in the battle to get light fire back into nature's ecosystems in the 20th Century, and offers solutions to transform a dysfunctional and misguided culture of fire suppression into a culture of good fire management.
