In the early 1990s, ancient temperate rainforests on Vancouver Island became the stage for mass blockades against clearcut logging in Nuucaanul territory. Until the more recent struggles at Fairy Creek, Clayoquot Sound hosted the largest act of civil disobedience in Canada. National news coverage at the time showed mothers with their babies, grandparents, business people, and many other unlikely activists standing on the logging road or locked to makeshift structures, risking arrest to defend these rare, evolved ecosystems. Drawing from her daily journals recorded at the time, Lowther recounts the vibrant and tense atmosphere of confronting police and loggers with nonviolent civil disobedience. She vividly describes creative direct actions-- themed blockades, lock-downs, nighttime barricade building, occupations of ancient trees and government offices. Blockade contemplates the stark realities of the movement, including threats of police violence and the disturbing collusion between the RCMP and extraction corporations, and is a rallying cry of hope for all those who stand up for the natural world and a roadmap for future generations of defenders.
