1 Dollar Central Catchment

Issued as part of Singapore's ongoing Nature Series, this piece commemorates the Central Catchment Nature Reserve — the largest of Singapore's four nature reserves and the remnant core of the primary rainforest that once covered the entire island. The reserve surrounds the island's main reservoirs, a relationship that became infrastructurally critical as Singapore pushed toward water self-sufficiency following its 1965 separation from Malaysia, after which Kuala Lumpur's control over Johor water supplies became a persistent political vulnerability.
