BLUE: Biodiversity Literacy in Undergraduate Education was founded in 2016 in response to growing interest in the biodiversity community to build upon resources that integrate research-quality data with educational materials. Our work builds upon the accomplishments of past initiatives, such as AIM-UP!, and partners with current projects, such as QUBES, BCoN and iDigBio, to support and promote biodiversity literacy in undergraduate classrooms. Thanks to international digitization efforts, more and more biodiversity data are available everyday. These, in combination with Big Data from other disciplines such as climate science, geography, and ecology, set the foundation for robust educational materials. We take a broad, inclusive approach to our work and welcome collaboration with interested parties.
