One more plug for citizen science projects from the conference at Cornell:
Got purple loosestrife (Lythrum salicaria) in your neighborhood? If so, the US government needs you to help answer important questions about the invasiblity of this plant.
Back in 2003, the USGS partnered with the Great Lakes Research and Education Center to create a citizen science project to monitor purple loosestrife in the Midwest. Last week I had the pleasure of speaking with Dr. Joy Marburger about the Purple Loosestrife Volunteers program and found her to be very passionate about it. But you don't have to be from the Midwest or even the USA to join in - they are seeking volunteers from all over the world.
Dr. Beth Middleton from the USGS National Wetlands Research Center has undertaken the job of compiling all the data, in order to assess the characteristics of purple loosestrife in both its native and introduced range. The program is looking for people who are willing to locate loosestrife populations and make a few simple observations, such as plant height, number of stems per plant, and tree canopy cover. The data could be used to determine, for example, whether the range of purple loosestrife will be altered by climate change (by taking a look at the vigor of plants along the edge of purple loosestrife's range).
