Abscission can also occur in trees outside of autumn shedding and dormancy. Leaves of plants can abscise as a means of plant defense. Some examples of this are: dropping of insect-damaged and diseased leaves for water conservation; leaf fall after biotic and abiotic tree stresses including chemical contact, excessive sunlight, and heat; increased contact with plant growth hormones.

Fraxinus americana, commonly called white ash, is native to eastern North America. In Missouri, it typically occurs in dry and rocky upland woods, glades and moist low woods along streams, bluffs and slopes throughout the state (Steyermark). All leaves have a definite life span and are dropped following receipt of internal or environmental signals.

The process is termed abscission and is facilitated by the formation of an abscission zone at the base of the petiole. Plants that drop all of their leaves within a short time resulting in a temporarily bare, leafless plant are called deciduous plants.

Fraxinus Americana is a deciduous Tree growing to 25 m (82ft) by 15 m (49ft) at a fast rate. It is hardy to zone (UK) 3 and is not frost tender. It is in flower from April to May, and the seeds ripen in September.
