VertNet is a NSF-funded collaborative project that makes biodiversity data free and available on the web. VertNet is a tool designed to help people discover, capture, and publish biodiversity data. It is also the core of a collaboration between hundreds of biocollections that contribute biodiversity data and work together to improve it. VertNet is an engine for training current and future professionals to use and build upon best practices in data quality, curation, research, and data publishing. The VertNet team includes collaborators from the Universities of California, Colorado, Kansas, and Tulane, and partners from wide-range of biodiversity projects, who are working to build upon the successes of four classic vertebrate networks (FishNet, MaNIS, HerpNET, ORNIS), to combine them into a single integrated data portal, and solve the problems that these networks face.
