In celebration of World Environment Day, a group of Hillgrove Secondary School students organized a fundraising sale at Sungei Buloh Wetland Reserve on 2 June 2007 in support of the wetland’s conservation efforts. They sold terrariums, painted stones and batik bookmarks. They managed to raise $300 for the wetland’s Conservation Fund.

On 5 June 2007, HSBC organized a half-day programme for some 80 staff children as part of World Environment Day celebration. The children went on a guided walk led by a team of HSBC Green Volunteers. This were followed by a tree planting activity. The children planted some 30 Calophyllum inophyllum, Dolichandrone spathacea and Melastoma malabathricum around the wetland reserve.
