Conservation Status: Special Concern

Description:

The Butternut is also called white walnut. It is native to the eastern United States. The butternut grows further north than the black walnut. Moreover, the nuts are edible and have a mild flavor.

Butternut trees are commonly found in floodplain benches and rocky slopes. They are partially shade tolerant, needing small openings to reach for sunlight. This species of tree does not tolerate fire. Once exposed to fire, butternut trees do not re-sprout.

Trees live 60 years and begin producing nuts when approximately 30 years old. They grow to 50-60 feet tall.

The Butternut is listed as an species of special concern in the Wisconsin Natural Heritage Inventory, which lists rare species in the state (endangered, threatened and special concern). Its listing is because butternuts commonly suffer from a canker that has greatly reduced their numbers.
