Interaction between Ailanthus altissima and Native Robinia pseudoacacia in Early Succession: Implications for Forest Management

The study looked at interactions between an exotic invader, tree-of-heaven (Ailanthus altissima), and coexisting black locust (Robinia pseudoacacia) and management implications. The study occurred in the Mid-Appalachian region of the eastern United States where black locust is native. Results showed that in early successional sites, tree of heaven should be removed to promote long term community succession in areas where black locust is native.

Dose-response Methodology for Variant Populations of Bohemian Knotweed

Dose-response Methodology for Variant Populations of Bohemian Knotweed

Strelau et al tested herbicide tolerance in two Bohemian knotweed (Reynoutria × bohemica Chrtek & Chrtkov) populations using rhizome fragments. Results showed there was no difference between populations and knotweed was susceptible to the herbicide treatment. Published in 2018 in Canadian Journal of Plant Science 98(6):1380-1383.

New Invader! The Biology of Canadian Weeds: 156. Daphne laureola L.

New Invader! The Biology of Canadian Weeds: 156. Daphne laureola L.

Spurge-laurel or “Daphne” (Daphne laureola L.) is an invasive, perennial, evergreen shrub introduced to North America as an ornamental. The plant escaped cultivation and is now found on both the east and west coasts of North America. All parts of the shrub are toxic to humans and animals, and dense infestations suppress native vegetation. Strelau et al. 2018. Canadian Journal of Plant Science 98(4):947-958.

Native Hardwood Tree Seedling Establishment Following Invasive Autumn-Olive (Elaeagnus umbellata) Removal on a Reclaimed Coal Mine

Native Hardwood Tree Seedling Establishment Following Invasive Autumn-Olive (Elaeagnus umbellata) Removal on a Reclaimed Coal Mine

Coal mining has caused large-scale disturbance on over 1.5 million acres in Appalachia. Invasive, non-native autumn olive was historically planted on former coalfields and now impedes reclamation efforts. Read about studies conducted by Virginia Tech on managing autumn olive and restoring native hardwoods.
