Activists say they exposed themselves to make themselves vulnerable, just like the thousands of trees.

“The first claim that it will make the hills less prone to fire is not true,” said Jack Gescheidt, founder of The Tree Spirit Project. “Very simply you’re turning living forest canopy that is actually fire resistant despite the species — despite the claims of eucalyptus trees being so dangerous — it will actually become dead wood on the ground, which will burn.”
