Peter Wohlleben (born 1964) is a German forester and author who writes on ecological themes in popular language and has controversially argued for plant sentience.

As he grew more familiar with the woodlands he was overseeing, he became disenchanted due to the damage caused by the techniques and technologies he was expected to employ, including the felling of mature trees and the use of insecticides.

The appearance of his Das geheime Leben der Bäume through Random House's Ludwig imprint led to profiles[12][13] and reviews[14] in all the major German newspapers, including skeptical pieces in the business press.

[22] The book was widely criticized by biologists and forest scientists for using strong anthropomorphic and teleological language such as describing trees as having friendships and registering fear, love and pain.

He appears alongside Suzanne Simard, a professor of forest ecology at the University of British Columbia, who has been doing research on interactions among trees through micorrhizal networks since 1997.

[28] In 2016, Wohlleben authored Das Seelenleben der Tiere, which was translated into English and published under the title The Inner Life of Animals: Love, Grief, and Compassion—Surprising Observations of a Hidden World in 2017.
