Author and science writer Mary Roach discusses killer trees, danger tree assessors, and the use of explosives to mitigate the risks posed by enormous dying trees. The podcast also delves into the art and danger of tree felling, highlighting the importance of understanding and respecting nature's risks.
Old, large 'danger trees' can unexpectedly fall due to rot, posing risks to visitors and wildlife.
Tree assessors use high explosives like the 'Faller Blaster' to mitigate risks from decaying trees in Cathedral Grove.

The Dangers of Trees
Trees can pose unexpected dangers, with incidents of people getting killed by falling fruits like durians and pine cones. Mary Roach, a science writer, explores the concept of 'danger trees,' which are old, large trees that can unexpectedly fall due to rot. Tree assessors monitor these trees, like in Cathedral Grove, to prevent casualties by either taking action or explosively removing the top parts to reduce risks.
The Process of Mitigating Tree Dangers
Dealing with 'danger trees' requires unique methods, such as bringing in high explosives after assessment. The 'Faller Blaster,' like Daisy Wamer, strategically removes the tops of trees to make them lighter and safer during their decaying phase. This process, while explosive, aims to protect the environment, wildlife, and visitors by ensuring stability and reducing potential hazards.
Public Perception and Controversy
Despite the safety intentions behind exploding trees, the practice can be controversial, especially for those emotionally connected to nature. Explaining the necessity of taking preventive measures with dead trees, like in the case of 'danger trees,' is crucial to mitigate public concerns. Mary Roach's insights from her book 'Fuzz' shed light on how nature, including seemingly harmless plants, can possess hidden dangers, reshaping perspectives on the natural world.
We promise, this is not another sappy (pardon the pun) story about trees. Instead, author and science writer Mary Roach takes us deep into an ancient forest grove on Vancouver Island, in search of the danger trees and the people who seek them out.
