Understanding the Biology, Ecology, and Integrated Management of Ventenata dubia
The non-native annual grass Ventenata dubia (Leers) Coss., is a newly emerging threat to grassland habitats in Montana and neighboring states. Three independent studies were conducted to explore the biology, ecology, and integrated management of V.dubia populations in Montana.
- A growth chamber study revealed elevated climate conditions affected competition between Bromus tectorum and V. dubia.
- A field-based herbicide efficacy trial determined a new herbicide mode of action can provide up to three years of control V. dubia, with potential implication to plant community succession.
- A revegitation study determined priority effects can occur with fall and early spring seeding of perennial grass species, Pseudoroegneria spicata, with implications for restoring grasslands impacted by invasive annual grasses like V.dubia.
