Invasive weeds may look forward to climate change

Dr. Dana Blumenthal and colleagues explain their invasive weed research during a tour of The Prairie Heating and Carbon Dioxide Enrichment (PHACE) Experiment in Wyoming. In this test plot higher temperature and richer CO2 conditions are being simulated to study their effects on invasive weed growth.

Most climate models paint a bleak picture for the Great Plains a century from now: It will likely be warmer and the air will be richer with carbon dioxide. Though scientists don’t yet know how exactly the climate will change, new studies show it could be a boon to some invasive plant species.

Invasive Species series continues on Playa Country

Oklahoma Historical Society

The second in the three-part series on invasive species airs this week on Playa Country.  On Tuesday at 6:44 pm central time, Biologist Gene Miller describes the problem with invasives along the banks of the Canadian River in the Texas panhandle and western Oklahoma. He and NRCS rangeland manager Clint Rollins created the consortium the Canadian River Cooperative Weed Management Area, a group of agencies, non-governmental organizations and landowners conducting invasive weed control efforts.
