Researchers Publish Findings on Consequences of Ventenata to Native Bunchgrasses
January 25, 2021
A research article by U of I Research Specialist Lisa Jones, Professor Tim Prather and alumnus Cleve Davis was recently published in the Invasive Plant Science and Management journal. The article describes the patterns of the annual grass ventenata and its infestation of Palouse prairie and canyon grasslands of North Idaho over the past 30 years. The study revealed that ventenata was the dominant invasive species in these ecoregions, and it may be contributing to native species declines and possible local species extinctions, particularly of desirable native bunchgrasses. This research will assist with management efforts such as detection, monitoring and treatment of infestations. Findings may also foreshadow what will happen in the sagebrush steppe and Great Plains, expansive areas that provide critical value to humans and native biodiversity, where ventenata recently became established.
