Green Wave
Green Wave is a worldwide biodiversity campaign that educates children and youths about the importance of protecting our natural environment. As Singapore continues to urbanise, we should all strive to keep our City in Nature green and vibrant.
Each year, students from around the world plant locally important trees in their school compounds at 10 am on the International Day of Biological Diversity, 22 May. This creates a figurative “green wave” that begins in the Far East before eventually rippling across the globe.
As part of Green Wave, schools may select up to five plants from either a native shrub or tree species to be planted within the school compound.

Resources for Green Wave:
NParks will provide a Green Wave 2023 Infokit as reference to conduct the activity this year.
*Registration is now open.
Playtime with Hershie the Hermit Crab
Pre-school students (K1/K2) can learn about our intertidal wildlife by watching a video about a hermit crab named Hershie and his journey in search of a new shell. An interactive sticker book accompanies the video.
Resources for Playtime with Hershie the Hermit Crab:
Materials for Playtime with Hershie the Hermit Crab will be provided by NParks and delivered to the participating schools, to be administered by the teachers.

BioBlitz for Schools
BioBlitz is a form of collaborative wildlife survey to document as many species of flora and fauna as possible, within a set location, over a defined time period.
Upper primary and secondary school students can conduct wildlife surveys in their own campus as part of a nation-wide initiative to document our urban biodiversity.
Resources will be provided to classes and/or CCA groups to learn wildlife survey techniques and how to identify common birds, butterflies and dragonflies. Each school will then select a group of students to participate in a formal survey where they collect the data and submit it to NParks.

Resources for BioBlitz for Schools
Materials for BioBlitz for Schools will be provided by NParks to the participating schools, to be administered by the teachers. Download the Common Birds of Singapore, Common Butterflies of Singapore and Common Dragonflies of Singapore posters for more information.
* Registration is now open.
Festival of Biodiversity
The Festival showcases Singapore’s impressive and unique array of native flora and fauna. We hope that this event, which celebrates our natural heritage, will bring about greater awareness of Singapore’s rich biodiversity. Students can look forward to a range of interactive activities and exhibitions by NParks and our interest group partners.
