Getting started
Understand what citizen science is
Volunteers collecting, classifying, or contributing data to real research projects. You don't need a science background — the value comes from large numbers of consistent observations across many contributors.
Start your first Zooniverse project
Zooniverse hosts 100+ active projects from galaxy classification to penguin census. Galaxy Zoo is a reliable first choice: visually clear tasks with immediate on-screen guidance.
Set up iNaturalist
Photograph a plant, animal, or fungus — the AI suggests an ID, experts confirm it. Every observation goes to GBIF (Global Biodiversity Information Facility) and is used in real research.
Scientific contribution
Contribute data cited in research
iNaturalist observations are cited in thousands of peer-reviewed papers — you can track this on your iNaturalist profile. Consistent, well-documented observations in under-recorded taxa are most valuable.
Train and mentor new recorders
Running a local recording walk or online ID session is how recording schemes grow their base. Your expertise becomes other people's starting point — this is how species knowledge transfers.
Take a beginner Citizen Science course

Mycology is one of the most intellectually rich hobbies you can start — and one of the cheapest. This guide covers everything a beginner needs to know: the three ways to get into it, what equipment actually matters, how to identify safely, and how to find the community that will accelerate everything.

Birdwatching costs nothing to start and scales from a casual morning walk to a serious lifelong pursuit contributing to real science. This guide covers everything you need for your first session and your first year — including the one app that changes everything.

When in doubt, mark "Uncertain" rather than guessing. One wrong observation is harder for researchers to filter than one missing one — accuracy matters more than volume.
