Citizen scientists currently play an active role in a wide range of ecological projects. Citizen science projects, like eBird, have enabled scientists to collect large amounts of data over wide areas at a minimal cost. From 2008-2012, I was the Invasive Species Coordinator at the Lady Bird Johnson Wildflower Center at the University of Texas. As coordinator, I ran the Invaders of Texas citizen science program and was responsible for communicating with over 1,000 citizen scientists, promoting the program, conducting citizen science training workshops, validating all invasive species observations, public outreach efforts, and worked on various other invasive species related projects. Through my efforts growing this program, I earned the 2012 Public Servant and Leadership Award from the Texas Invasive Plant and Pest Council. More recently I have focused on, not just using citizen science data, but also understanding the strengths and limitations of using citizen science data in ecological research.
