Invasive Species Awareness Week
Today is the start of the 2011 National Invasive Species Awareness Week (NISAW), a week of activities, briefings, and events to highlight what is being done across the nation and around the world to stop and slow the spread of invasive species. Even if you are not in Washington DC, you can participate through web seminars. On March 1st, NISAW will be hosting an interesting web seminar on "Elements of Effective State and Regional Coordination" at 1:15 pm. To login and listen to presentations visit http://www.nisaw.org/webinars.html.

Invasive Spotlight: Bastard Cabbage
(Rapistrum rugosum)
Native to Central Europe, the Mediterranean, northern Africa and western, temperate Asia, bastard cabbage (Rapistrum rugosum) was introduced through contaminated seed mixes. It is an annual herbaceous plant that grows from 1 to 5 feet or more in height and has a taproot that can become quite large. Leaves are deep green, lobed and wrinkled, and sometimes have a reddish cast. Bastard cabbage typically flowers from early spring into summer, bearing clusters of small, showy "highlighter-yellow" flowers at the tips of its branches, resembling those of broccoli and cabbage.
Bastard cabbage seeds germinate early in the growing season and quickly cover the ground with a blanket of leafy rosettes. These dense rosettes block sunlight from reaching seeds and seedlings of native plants. In some places, it forms a monoculture out competing all other vegetation.
