City Nature Challenge Australia

About The City Nature Challenge

In 2020, Australia will be participating in the City Nature Challenge for the first time! The program was started in 2016 by the Natural History Museum of Los Angeles and the California Academy of Sciences as a competition between Los Angeles and San Francisco. Since this time the event has grown and become international. In 2019, there were more than 35,000 participants from 159 cities, documenting over 963,000 observations of plants and wildlife. With over 31,000 species identified it is an impressive grass roots effort with over 1,100 species observed being rare, threatened or endangered! With four cities entered it is an exciting time for Australian Citizen Science! Help your ‘city’ collect biodiversity data and see how we compare with other cities from around the world you can do this by making natural observations from April 24-27, 2020. Let’s show the world the incredible diversity Australia has to offer and it will be interesting to see the diversity of o. From koalas and kangaroos, to flora and fauna of all shapes and sizes!

Impact of COVID-19

Research shows that being in nature has a range of health benefits, and is linked to reduced type II diabetes, cardiovascular disease, lowering blood pressure reducing stress among other things. Being in Nature can also provide overall positive feelings of well being. This April let’s channel these positive aspects of the City Nature Challenge in this time of disease.

  • We will follow the guidelines/recommendations of The Australian Government Department of Health
  • Due to the risks associated with COVID-19, we are suggesting the following alternatives to our previously planned events:
    • Join our ‘Backyard Bio-blitz’, what can you find in your house or in your own backyard?
    • Join our moth lights or put down cover boards at their houses to help bring nature to them!
    • Join our “Backyard Bio-blitz” making observations on the biodiversity of your own backyard.
  • If you are working with others
    • Practice social distancing (it’s best if people stay ~2m apart)
    • Don’t share, unwrapped food
    • Ensure everyone washes their hands and/or have hand sanitizer
    • Don’t pass around equipment such as binoculars, phones, guidebooks, etc.
    • After April 28 – May 3, hold virtual ID parties!
