The City Nature Challenge is a global event that takes place every year at the end of April, it consists of two parts:
- Recording – cities partake in a global bioblitz and take photos and recordings of the wild nature (plants and animals) they find during the four-day period
- Identifying – cities upload their observations to iNaturalist and add identifications to the recordings
| Part breakdown | Dates for the 20206 City Nature Challenge |
| Recording | 24 – 27 April 2026 |
| Identifying | 28 April – 10 May 2026 |
The North East of England is registered to partake in the 2026 City Nature Challenge, and our project has been set up on iNaturalist.
Below is an overview of how you can get involved and a guide on how to use iNaturalist to partake in the City Nature Challenge.

How can I participate?
Recording:
- Download the iNaturalist app
- Join the City Nature Challenge 2026: North East England Project
- Find wildlife anywhere within the North East project boundary and take a photo or make a sound recording of what you find as evidence and note when and where you found it
- a. Wildlife includes any organism that has not been planted or looked after by humans. Focus on finding bugs, birds and weeds instead of planted flowers and trees or animals that are looked after by humans.
- Upload your observations to iNaturalist
Identifying:
- Find the City Nature Challenge 2026: North East England Project on iNaturalist
- Go to the Observations tab and click ‘Identify’
- Filter the results by ‘Casual’ and ‘Needs ID’
- Search through the results and find an observation you may be able to add in identification too, click the image and use the ‘Add ID’ button, type in what you think it may be – this can be broad. Save your identification
- a. Add identifications to the taxonomic level that you are confident of, use the evidence provided in the observation.
- b. You can use different sources to help you if you are not sure, such as all the images uploaded in the observation, identification sheets, ID books and apps such as Merlin ID to help
How to make an observation for the City Nature Challenge
An observation records an encounter with an organism in a particular time and location. Observations can be uploaded via the mobile app or the webpage.
| Making an observation with the app | Making an observation on the website |
| Open the iNaturalist Classic app and tap “Observe.” | Log in at iNaturalist and click the green “Upload” button in the header. |
| Add one or more photos or sounds as evidence | Drag in one or more photos or use the “Add” button to manually create observation cards. |
| Choose what you saw – either from suggested species or by searching. If you are unsure, you can keep the label as simple as “plant” or “insect.” | Choose what you saw from suggestions or by searching. If unsure, leave it blank or use a broad category. |
| The date and location should be added automatically. If not, check your device’s location and privacy settings. | Use the calendar to record when the observation was made. |
| Does the plant look like it was planted or is looked after by a human? If yes, mark the finding as ‘captive/cultivated’ as this is not a wild observation. | Enter a location and adjust the map marker and accuracy circle as needed. |
| Tap “Save”, then “Upload” to share your observation. | Does the plant look like it was planted or is looked after by a human? If yes, mark the finding as ‘captive/cultivated’ as this is not a wild observation. |
| Once uploaded, others in the iNaturalist community can help refine the identification. | Once all details are added, click “Submit.” |
Please note: Non-wild observations need to be marked as captive/cultivated on iNaturalist.
Additional guidance
iNaturalist have shared a slideshow that contains helpful tips about how to make a good observation. The key principles are:
- Take clear, close-up photos
- Focus on wild organisms
- Document the location
- Add an identification

Why are observations important?
iNaturalist is an important tool that helps connect people with the nature around them and build their knowledge of biodiversity. Through iNaturalist and the City Nature Challenge, your photos and identifications contribute valuable data that supports research, conservation, and our understanding of local biodiversity.
At Newcastle University, these records contribute to our Campus Biodiversity Network and help us establish our biodiversity baseline, allowing us to monitor species over time and better understand our campus biodiversity. Whether you’re recording or identifying, every contribution counts, so get involved in this year’s City Nature Challenge!
If you would like to find out more about other biodiversity initiatives on campus, check out our webpage. For any queries about iNaturalist or sustainability in general, please email us at sustainable-campus@newcasle.ac.uk.
Thank you for reading!
