Performance of hardwoods planted with autumn olive after removing prior cover

Abstract

White ash, white oak, and black walnut were planted with and without autumn olive on a site previously occupied by a 10-year-old stand of autumn olive. Seven years later, height, diameter, and foliar nitrogen were significantly greater in plots with autumn olive than in plots without autumn olive. White oak in plots previously occupied by autumn olive were larger in diameter but shorter than white oak in plots previously inhabited by shrubs and scattered hardwoods. Prior cover of autumn olive apparently did not increase growth more than prior cover of shrubs and scattered hardwoods.
