Identification
Common names: Tree of Heaven. Scientific name: Ailanthus altissima. Family: Simaroubaceae.
Tree of Heaven is a woody species where bark, leaf arrangement, and fruit or seed structures are needed for reliable field ID. Always verify leaf, stem, flower, and growth habit together before forage, browsing, or harvest decisions.
Habitat and Range
Common along field edges, unmanaged hedgerows, and disturbed woodline transitions. In TN/KY transition farms, localized moisture and disturbance shifts can change where this plant appears year to year.
Most invasive woody stands expand aggressively in sun with moderate moisture. Match these site preferences to paddock pressure and rotational timing for practical control or utilization.
Ecological Role
Can suppress native diversity and alter browse pressure if left unmanaged. Ecological behavior directly impacts pollinator support, forage composition, and long-term weed management labor.
Agricultural and Homestead Value
Limited direct forage value; primary management goal is containment or removal. Practical value depends on livestock class, season, and total feed context rather than one plant in isolation.
Forage and management tags: aggressive volunteer tree, edge control.
Toxicity and Animal Interaction
Toxicity level: Moderate caution. Sap and tissues may irritate skin and can be problematic if trimmings are consumed. Chemistry context: Ailanthone and bitter quassinoid compounds are central to species behavior and caution..
Animals affected or monitored: goats, cattle, horses, dogs, cats. Symptoms to watch: digestive upset, off-feed, neurologic signs in severe cases.
Veterinary Response Notes
If active herd signs appear, remove exposure, preserve plant samples, and coordinate diagnosis with a veterinarian. If a herd event is active, preserve samples and timeline details for your veterinarian.
Historical and Cultural Uses (Archive Context)
Historical farm references are included for context and should not be treated as modern medical instructions. Historical references are archival context, not modern treatment protocols.
Historical remedy tags: historical cautionary.
Foraging and Cultivation Guidance
Use positive identification and clean harvest locations for any human or livestock-use decision.
Management should match season, growth stage, and the farm rotation plan.
