Asia’s biggest bioblitz is back!
The Asia Nature Challenge was created to help make Asia’s incredible biodiversity more visible, while encouraging people to reconnect with the nature around them. In 2025, 7,340 participants across the region shared observations of local wildlife through iNaturalist, showing how small moments of curiosity and wonder can come together to tell a richer story of Asia’s living world.
Explore ANC below and join a growing community celebrating nature, one observation at a time.
What is the Asia Nature Challenge?
Asia is home to some of the world’s most incredible biodiversity — from rainforests and coral reefs to mountains, deserts, and wetlands. It is also home to more than half of the world’s people. Yet, despite this richness, Asia is still missing from much of the global biodiversity conversation. Our analysis of iNaturalist data from 2023–2024 found that less than 9% of global observations came from Asia. Barriers such as limited internet access, language differences, and a lack of regional coordination continue to make participation difficult for many communities.
The Asia Nature Challenge (ANC) was created to help change this.
In 2025, ANC brought together 7,340 participants from across the region to document local biodiversity through iNaturalist. The edition also focused on learning and community building, with workshops on moths, dragonflies, and biodiversity documentation. Participants developed new skills and contributed exciting discoveries, including first-ever iNaturalist records such as the Androctonus caspius scorpion in Iran and the Clitocybula esculenta mushroom in Japan.
More than a biodiversity event, ANC is a reminder that anyone can take part in science and conservation. All it takes is curiosity and a willingness to notice the nature around you.
The ANC is a 10-day event with two simple phases, and everyone is welcome to join! From September 11 to 14, head outdoors and take a closer look at the nature around you. Photograph or record the sounds of any wild plants, animals, fungi, or other living things you find, and upload your observations to iNaturalist. From September 15 to 18, help identify what others have shared. You can also finish uploading anything you recorded during the observation days.
Whether you’re an individual, a school, a local group, or an environmental organisation, the Asia Nature Challenge invites you to explore, observe, and share the nature around you. Your contributions on iNaturalist don’t just stay on the app. They feed into global biodiversity databases and are used in real research and conservation efforts around the world. Every observation helps fill the gaps in knowledge about Asia’s wild species. Together, we can grow Asia’s role in citizen science and build a deeper connection with the living world around us.
What Are the Key Goals?
ANC intends to inspire communities across Asia to become active contributors of citizen science. By documenting local flora and fauna, participants can deepen their connection with nature and contribute to a larger conservation mission. The project key goals include:
- Expand Citizen Science Participation: Mobilise diverse communities across Asia to actively engage in documenting the region’s biodiversity, fostering a sense of environmental stewardship and involvement.
- Enhance Biodiversity Data Quality: Increase the percentage of verifiable and research-grade observations, ensuring that data collected is reliable and valuable for conservation and scientific research.
- Fill Data Gaps: Target under-explored regions and lesser-known species, encouraging observations from areas previously undocumented to provide a comprehensive understanding of Asia’s unique ecosystems.
Aligned with CitizenScience.Asia’s broader mission, the ANC also emphasises building connections by strengthening networks among established citizen scientists and environmental organisations, building capacity by making accessible digital tools and educational resources to reduce barriers and enhance participants’ skills, and building conversations by fostering dialogues with social entrepreneurs and policymakers to amplify Asia’s voice in global biodiversity discussions.
How to Get Involved
Taking part in the Asia Nature Challenge is easy and rewarding! As an individual, you can join as a participant during one or both phases of the event: Observation and Identification. If you or your affiliated organisation would like to do even more, consider becoming a collaborating organiser!
FAQs
What is the Asia Nature Challenge?
The Asia Nature Challenge is a continent-wide initiative encouraging people across Asia to observe and document nature and wildlife in their local areas using the iNaturalist platform.
Who all can participate? How do I participate?
Anyone in Asia can participate! Whether you’re a nature enthusiast, student, or just curious, all are welcome to join and share observations. Simply explore nature in your area, record findings of plants, animals, or any other organisms, and share them to the iNaturalist during the event observation period (October 18-21). You can also participate by assisting with identification of the collected observations during the identification period (October 22-27).
Be sure to sign up to let us know so we can provide additional guidance and a certificate to recognise your effort!
How does identification work? How do I do that?
Experts on iNaturalist who can identify will give you identification for your observations, you can also contribute to identifying observations by putting them into lowest classification you know about the observation.
Can we upload videos as observations?
No, there is no support for uploading of video observations on iNaturalist at this point.
What types of observations are valid?
Any wild organisms like plants, insects, birds, or fungi, any evidence of their presence can be uploaded as an observation. Domesticated animals or plants in gardens (casual observations) do not count as wild observations and will not be considered for this event.
How can I help promote the challenge?
You can help by sharing the challenge on social media and inviting your friends, family, and community to join and share their observations. Hashtags #AsiaNatureChallenge and #CitSciANC2024 will be used for this event, so use them widely. Have fun!
