Ventenata dubia in the Zumwalt Prairie Preserve in northeastern Oregon: Foliar response to grazing and fire treatments

This data publication includes a sample of the frequency and foliar cover of Ventenata dubia (ventenata) in June and July 2008, 2016, and 2018 in the Zumwalt Prairie Preserve in northeastern Oregon. In addition to these measures, the density of ventenata was also recorded in 2016 and 2018. These data describe the trend in ventenata abundance through time under differing treatments of grazing and fire. This project was completed as a component of a study examining the invasion of ventenata in the Blue Mountains Ecoregion (EPA Level III; https://www.epa.gov/eco-research/level-iii-and-iv-ecoregions-continental-united-states).These data were collected in an effort to examine the effect of cattle grazing, fire, and their interaction on the abundance of ventenata in the Pacific Northwest Bunchgrass Prairie through time. Ventenata's invasion is relatively recent in this region and the existance of an established network of monitoring plots allowed a view of the ventenata invasion in a unique and uncommon plant community of the Pacific Northwest.More information about the larger study can be found at https://www.nwfirescience.org/ventenata#Extent_of_Ventenata.
