Invasive Plants Update - comment
Yosemite National Park released the Invasive Plant Management Plan Update (IPMP Update) Environmental Assessment (EA) for a 45-day public review, ending January 30, 2011. The IPMP update was built upon key elements of the existing plan (Invasive Plant Management Plan for Yosemite National Park, NPS 2008) to provide a more adaptive, efficient and effective framework for responding to the growing challenges of managing invasive plants while protecting Yosemite’s natural and cultural resources.
The IPMP Update describes three alternative approaches for protecting the park’s natural and cultural resources from displacement or other degradation resulting from the introduction and spread of invasive plants. Management under each of the alternatives would be based upon the tested principles of integrated pest management (IPM), a process for ensuring that the most effective techniques (cultural, physical, biological, or herbicide) are used to protect resources, while posing the least possible impact to people and the environment. Elements of IPM include prevention, inventory, prioritization, treatment, monitoring, research, education, and outreach. Under Alternative 3, the preferred alternative, adaptive management would enable effective protection of park resources. Additional herbicides would be assessed for inclusion based upon literature review and expert consultations. In the event of a serious aquatic infestation, managers would use a similar process to evaluate the option of using herbicides specifically developed for water.
The public was invited to discuss the plan and accept comments with park staff on January 5, 2011 at the El Portal Community Hall from 1 to 3 p.m. Park staff also discussed the plan and accepted comments at the January 26 Open House at the East Valley Auditorium in Yosemite Valley from 1 to 4 pm. Printed and CD copies of the plan were be available. The public comment period closed January 30, 2011, but a digital copy of the EA is still available on the Planning, Environment and Public Comment (PEPC) website.
