Gleditsia triacanthos (Honey locust): Ecology

Habitat: Although intolerant of shade, the honey locust is extremely adaptable and tolerant of drought, high pH and saline conditions. Agriculture has created an ideal habitat in Iowa where this tree has become a pasture and fencerow weed.

Diseases: Diseases and pest infestations have dramatically increased in areas where continuous plantings of this tree occur, with mimosa webworm, borers and several fungal cankers becoming the primary problems. Leaf spot, witches' broom, powdery mildew, rust, midge pod gall and spider mite are also reported.

Distribution:The honey locust is common in the midwestern and south central US on floodplains and in limestone soils. It is native to southern, eastern and central Iowa and is widely planted throughout the state.
