Abstract

Alien and native woody species invasion of abandoned crop land and reestablished tallgrass prairie in East-Central Illinois.

Abstract

A study of the composition and density of woody species within a successional old field and a sown tallgrass prairie community at the Eastern Illinois University Environmental Biology Area was conducted in the spring of 1988. Woody plant invasions exceeded 16 500 stems/ha in the sown tallgrass prairie and >6500 stems in the old field. A number of alien species, including autumn olive (Elaeagnus umbellata), multiflora rose (Rosa multiflora) and Siberian elm (Ulmus pumila) were present in relatively high numbers, whilst the most common native species encountered were poison ivy (Toxicodendron radicans), blackberry (Rubus allegheniensis) and dewberry (Rubus flagellaris).
