In our complex and data driven world, scientists are facing a major challenge to understand and document plant and animal species that may be in the process of disappearing. Climate change, habitat fragmentation, pollution and population growth are among the threats that are pushing some species toward extinction.

Known as citizen scientists, these volunteers are using their eyes, ears, and observations about the natural world to help scientists find answers to critical questions.
