What happened to this maple tree?
Answer
A failed attempt at girdling. This wolf maple was double-girdled with a chainsaw a few decades ago but the cuts were either not sufficiently deep or did not completely ring the tree and enough cambium was left to keep the tree alive. New growth has partially grown over the girdle cuts. Girdling is a common practice in forest management for killing trees while leaving them standing and is often used on larger trees that are too dangerous or time consuming to fell. Girdling trees frees up resources and growing space and also creates standing dead trees, which, over time, can provide important wildlife habitat.
