Last year, Hong Kong came second out of 419 cities in the number of different species observed. Hong Kong is a biological treasure chest.

Let’s get the data out there and help protect our riches into the future.

Here’s how to play

  • Download iNaturalist or Seek by iNaturalist onto your smartphone and register your free account.
  • Find any plant, animal, fungi or anything alive in and around your community
  • Identify as many specimens as you can; both wild and captive or cultivated (i.e. urban park flora)
  • Observations that are taken in Hong Kong between 29 April – 2 May will be automatically included in Hong Kong’s City Nature Challenge project.

Take photographs of nature (trees, plants, insects, birds, fungi, fish, reptiles, rocky shore, mangroves, etc) and upload them onto iNaturalist during event dates.  All observations will be collected automatically plus there’s no need to register for the local Hong Kong project.

Please take all the necessary precautions and follow guidelines to ensure your safety and that of your community.

NOTE: DO NOT take pictures of pets, potted plants, selfies, market fruits or vegetables or drawings of other animals.
