A quick blog post today to share a recent edition of "TechLine - Invasive Plant News" that I was forwarded recently.
The Spring 2013 issue of the Western Range and Wildlands edition features an article by Celestine Duncan entitled "Protecting the Merced River Canyon from Invasive Plants - Yosemite National Park and Interagency Partners Tackle Yellow Starthistle". The combination of yellow starthistle and the national park system presents a interesting challenge for weed managers.
This publication is sponsored by DowAgroSciences (Techline, that is, not the UC Weed blog) but the article presented information on several selective and non-selective herbicides used in combination with other weed management tactics. I think it does a nice job of explaining some of the challenges in wildland weed management (especially in the photos).
I'll pull one quote from D.Greenwood, River Ranger for the BLM Merced River Recreation Area: “In California it seems weeds are everywhere,” says Greenwood. “Most of the other rivers canyons we manage are full of yellow starthistle and other invasive plants. The Merced River Canyon is one of our success stories.”
Click here for a link to the Spring 2013 Techline and read the yellow starthistle article as well as an article on "Innovative Conservation Approaches for Russian Olive and Saltceder Managemenet in the Missouri River Watershed"
Take care,
Brad
