Detective Dendro®

International Society of Arboriculture

Since its conception in 2004, Detective Dendro, the Diagnostic Sleuth, has been a highly popular print series with a regular feature in Arborist News magazine. In 2010, this educational and entertaining series became available as one of our ArborPod™ series.

Join Detective Dendro as he uses his professional knowledge of tree science, expert diagnostic skills, and gut instincts of a “hard-boiled detective” to investigate and identify his clients’ biotic and abiotic tree disorders. Assisted by his young apprentice, Codit, they inspect a wide range of mysterious tree afflictions, dispel the “red herrings,” and uncover the signs and symptoms that lead them to accurately diagnose trees in a variety of exotic places.
