However, due to extensive planting in the state, the species is probably now naturalized in most Missouri counties. It has been noted from prairies, open woodlands, and forest edges. Autumn olive rarely is encountered in dense forests or in very wet sites. Plants flower and develop fruits annually after reaching 3 years of age, although 2 year old plants have been known to flower. An individual plant can produce up to 8 pounds of fruit.
Seed dispersal appears to be mainly by falling fruit and birds.
Birds seem to be the primary vector for dispersal, although raccoons, skunks, and opossums are known to feed on the fruit. Once established, this species is highly invasive and difficult to control. Burned, mowed, or cut plants will resprout vigorously. It is sometimes planted in black walnut plantations because of its nitrogen-fixing capability and because its brushy growth form reduces predation on walnut saplings. Control Recommendations Recommended Practices in Natural Communities of High Quality Treatment approach can be either a selective or non-selective method depending upon site quality.
