IPM Enhancement Trials
A study of alternative weed management treatments is underway. These trials will closely examine the many ways that unwanted weeds and invasive plants can potentially be managed by methods other than traditional pesticides. Our IPM approach in parks has always evaluated and employed many such alternative methods, but this study will allow us to conduct scientific trials and collect information about their effectiveness, feasibility, and long term impacts. The trials are also investigating best management practices when certain herbicides are being used. The trial areas are taking place in areas of Gabriel Park, Willamette Park, Ladd's Addition Rose Blocks, and Powell Butte Nature Park. Parks Nature Services staff is coordinating and conducting the trials, working closely with other PP&R work units. This program will provide reliable information about the use of alternative methods and materials that can be exported to park staff, other public agencies, and the general public. The outcome of these efforts should be well-supported answers to various park management IPM questions. These answers can then be used to develop the very best practices for both our developed parks as well as our natural areas. With its leadership role in this area, PP&R is in an excellent position to test the boundaries of use of alternative methods, while continuing to responsibly maintain grounds using professionally acceptable methods. Check back for updates on the trials and their results.
