Big Tree Guardian is a 2026 documentary about a long-running effort to free Taiwan cypresses from steel cables in the mountains. The film centers on Dr. Hsu and the Tree Seekers, a team whose work developed from one discovery into a decade of tree rescues across Taiwan.

Story without spoilers

Ten years before the events revisited in the film, Dr. Hsu found a Taiwan cypress held in place by steel cables in the mountains. The discovery began an extended rescue effort and led the Tree Seekers to develop the tree-climbing and cable-removal skills needed to reach other giant trees in similar conditions.

Over the course of their work, the team rescued four named trees: Song Yun-Yun, Iron Man, Kingma and Fat Tiger. Big Tree Guardian returns to the original cypress after ten years, documenting the removal of its restraints and the decision to name it Sun Wukong. The documentary frames this process through a decade of memories and continuing contact with the forest.

What to expect

Viewers can expect a concise, conservation-focused documentary built around a specific rescue mission and the people who carried it forward. The premise combines mountain work, tree-climbing and the careful removal of steel cables with a broader record of the team’s decade-long connection to Taiwan’s forests.

The film’s 15-minute runtime suggests a compact account rather than an expansive survey. Its focus remains on the original cypress, the rescues that followed and the significance of returning to the tree after many years.
