CapeNature participates in the City Nature Challenge, a worldwide citizen science event

7 May 2021

By Natanya Dreyer, Team Leader, Learning and Awareness

The annual City Nature Challenge is a global community science competition to document biodiversity. The challenge is a bio blitz that engages residents and visitors to find and document plants, animals and other organisms within a specific boundary.

Cities around the world compete against one another to see who can make the most observations of nature, find the most species and engage the most people to participate. Knowing where and what species are in our cities help us to study and protect them. By garnering the support of the public and all major conservation organisations within a particular boundary, an incredible amount of data is able to be collected in a very short space of time.

Following a hard lockdown during the 2020 event, in 2021, South Africa and the Western Cape was finally able to fully discover and document its incredible wildlife in the great outdoors again. Both the City of Cape Town and the Garden Route Municipality entered the competition and CapeNature was there to help record species and arrange events for the public.

The event ran from 30 April to 3 May and in that time CapeNature events were held at the Lourensford and Hansekop sites in the Hottentots Holland Nature Reserve, Atlantis Area, Kammanassie and Gamkaberg Nature Reserves. 110 people attended these events with an estimated 1800 observations made. Participants included CapeNature staff, scientists and members of the public. Between 30 April and 9 May these observations will be uploaded and species names will be confirmed by specialists in the field. CapeNature’s contributions will be added to other participant organisations and individuals and the final result for the participating cities will be announced in the upcoming weeks.

The Critically Endangered Tradouw redfin (Pseudobarbus burchelli) is one of South Africa’s most range-restricted freshwater fishes. It is endemic to the Huis–Tradouw River catchment near Barrydale in the Western Cape. The species is listed as Critically Endangered due to its small and fragmented distribution, threats from invasive fish species, pollution, water abstraction, and habitat degradation.

CapeNature urges public not to unnecessarily remove chameleons following Garden Route storms

Members of the public are urged to assist wildlife responsibly following recent severe weather events in the Garden Route, and to avoid the unnecessary removal of chameleons from their natural habitat. Following severe storms experienced in the region over the last two weeks, many trees have lost branches or fallen entirely. As a result, some small animals have been displaced from their natural habitat.
