Klang Valley Joins the Global City Nature Challenge: A Decade of Discoveries

Klang Valley City Nature Challenge 2025

Thank you to everyone who participated in this year’s Klang Valley City Nature Challenge, whether as an observer, identifier, or by helping us organize this event. This year marks the 10th anniversary of the City Nature Challenge (CNC), and we’re proud to be part of this global movement to document biodiversity in urban areas.

The CNC is an annual four-day worldwide bioblitz held at the end of April, where cities engage in a collaboration-meets-friendly-competition to see how much can be achieved when we work together toward a common goal.

The Klang Valley CNC is organized by Sekitar Kita and Universiti Malaya. This year, the statistics for the Klang Valley area are as follows:

2,079 observations of plants and animals

827 identified species

96 observers

125 identifiers

Several training sessions on the City Nature Challenge (CNC) and the use of iNaturalist were conducted in preparation for CNC 2025:
