In recent years, scientific studies have led to concern about the health of honeybee and native pollinator populations. Launched in 2008, the Great Sunflower Project is a citizen science project that began "as a way to gather information about our urban, suburban and rural bee populations and to give you the tools to learn about what is happening with the pollinators in your yard." While this US-based program initially focused on pollinator visits to Lemon Queen Sunflowers, it has since expanded so that people throughout the country can participate by counting and reporting pollinators they observe visiting any type of plant. Those curious about what this project has revealed thus far will find maps and graphs in the explore section, as well as information on pollinators and resources for teachers. Readers interested in participating can register for free online and a quick start guide and instructions for counting can be found under the site's about section. To aid in identifying the different kinds of bees and other pollinators, a number of downloadable identification guides are also available as are printable data sheets. The Great Sunflower Project is directed by ecologist and conservation biologist Gretchen LeBuhn, a professor of biology at San Francisco State University.
