New Invasive Plants to Watch For: Sonchus palustris (Marsh sow-thistle)
Another Perennial mustard found in Wisconsin A small population of a new herbaceous perennial weed, perennial pepperweed (Lepidium latifolium L.) was recently discovered along a roadside in Green Bay. This plant is very similar to Canada thistle as it can invade croplands and natural areas causing near monotypic stands. Perennial pepperweed has become a major problem in other states as it has invaded alfalfa fields, pastures, rights of ways, and natural areas causing significant economic and environmental damage. It has been found in other Midwestern states, but this is the first siting in Wisconsin. A factsheet that provides detailed information how to identify and manage this plant can be found at http://ipcm.wisc.edu/Portals/0/Blog/Files/20/322/Perennial-pepperweed.pdf Remember we likely only have a few small infestations therefore it is important to rapidly respond to this pest and try to eradicate populations. Due to the perennial nature of this plant several years of monitoring will be required to claim victory, but this is feasible as long as populations are small. Fortunately The Brown County Invasive Species Team rapidly responded to this population, finding all nearby infestations and conducting management to eradicate populations.

A new invasive mustard called Hill mustard, is spreading throughout the southern part of Wisconsin. Major infestations have been reported in Green county near Monroe, with another patchy found in Lafayette county last year. Follow this link, http://ipcm.wisc.edu/Portals/0/Blog/Files/17/280/Hill%20Mustard%20Fact%20Sheet%20MR.pdf, to a factsheet that discusses this species and provides characteristics and pictures to help with identificaiton. Key traits to help differentiate it from other mustards are its robust yellow flowers (should be flowering right now - early June) and “warty bumps” on the stems. If you think you have an infestation of Hill mustard, please contact, Mark Renz, Extension Weed Scientist, Agronomy Department, University of Wisconsin Madison, at mrenz@wisc.edu, or 608 263-7437.

Species Based Invasive Plant Ranking Projects
|
Early Detection and Rapid Response (EDRR) is one approach to limit the spread of invasive exotic species. In recent years, several EDRR projects have been proposed or implemented in the Midwest and adjacent Canadian Provinces, including a survey which allowed project leaders to submit important information about their projects.

Maintaining Data on Invasive Species Maintaining data on invasive species can be a difficult and time consuming task. The types of data you collect depends on the types of questions you want to answer. Although there will always be some variability in the data you collect, you may find it useful to standardize the more general categories of data you will consistently collect. The North American Weed Management Association, http://www.nawma.org/, has developed a data collection standard for invasive plant monitoring in the western United States and it has been adopted by several federal agencies, including US Forest Service and the National Park Service. Although the NAWMA Standard may not include all of the data fields you feel are necessary, it does standardize some of the most commonly collected data fields. Click here to go
to a list of data forms that
are being used by different agencies for varying purposes. They are
categorized by general purpose for your convenience. Please note that
not all forms follow the NAWMA standard. If you find one of these forms
meets your data collection needs, or may act as a template for you
to begin your own data collection form, please feel free to download
the form to your computer. |

Strategies for Effective State Early Detection/Rapid Response Programs for Plant Pests and Pathogens The Environmental Law Institute announces the publication of “Strategies for Effective State Early Detection/Rapid Response Programs for Plant Pests and Pathogens,” a report by attorney Read Porter that assesses the utility of state early detection and rapid response (ED/RR) laws for identifying and stopping the spread of invasive plant pests and pathogens. The report focuses on invasive forest pests, which are often poorly controlled by agriculture-centric response laws and which may infect or infest suburban or urban areas, raising the specter not only of environmental damage but also significant economic and aesthetic costs. The report describes components of a successful ED/RR regulatory structure, explains federal regulations that affect state action for each component, examines the strengths and weaknesses of specific laws in fourteen states that have responded to invasive pathogens, and examines the performance of ED/RR laws in practice via in-depth case studies from New York and Texas. Porter concludes that states must enact laws that balance the need for broad state agency authority to act against the need to preserve private property rights, respect landowners’ privacy, and sustain public support. This report was produced by the Environmental Law Institute with funding and guidance from The Nature Conservancy. The report is available free of charge from ELI’s website, at http://www.elistore.org/reports_detail.asp?ID=11223. Contact Read Porter directly at (202)939-3810 or porter@eli.org.
