More than 2,000 species of bark beetles are found around the world. While many species attack already-stressed and weakened trees, helping to clean up dead wood, nonnative bark beetles also attack healthy trees, sometimes wiping out entire tree species. But even native bark beetle species can wreak havoc on forests. In the last decade, bark beetle outbreaks have been increasing, due to the warmer weather associated with climate change. This has devastated certain tree populations. In British Columbia, for example, 80 percent of the pine trees have been killed from bark beetle infestation. And in the U.S., millions of acres of forestland have been affected by the tiny insects, mostly in the Rocky Mountains and Western United States, including Colorado, Wyoming and drought-stricken California. The Backyard Bark Beetle venture is a citizen science project run by researchers at the University of Florida. The project uses volunteers who trap bark beetles in their yard, then send them to the researchers, who study the beetles' distribution and diversity. Researchers instruct volunteers how to create a low-cost bark beetle trap using a plastic bottle into which hand sanitizer (or antifreeze) is inserted. Here's a video showing how to make the beetle bottle trap used in the Backyard Bark Beetle project. There are hundreds of citizen science projects occurring around the world today in fields as diverse as ecology, astronomy, computer science, psychology and engineering. Typically, volunteers are involved in data collection, reporting and analysis. If you're interested in helping out on a citizen science project, check out National Geographic's FieldScope.
