It is estimated that over 10 million species of plant and animal live in rainforests. Though they cover only 6% of the Earth's land surface, they support over 50% of the planet's plant and animal species.

The Singapore Zoological Gardens' new Fragile Forest is an ecological display based on various rainforest ecosystems. It emphasizes the intricate inter-relationships between plants and animals in the web of life. The display is primarily on invertebrates but will also include small mammals, birds, fish and reptiles.

There will be two stamp booklets released for this stamp issue. Each booklet contains 10 No-Value Indicator (NVI) stamps featuring different animals. Each booklet comes with a "scratch-off" feature in the shape of a leaf. An animal will appear when the "leaf" is scratched. The ten animals featured on the stamps are: Rhino Beetle, Surinam Horned Frog, Atlas Moth, Green Iguana, Giant Scorpion, Hissing Cockroach, Two-toed Sloth, Archer Fish, Cobalt Blue Tarantula and Greater Mousedeer.

This set of stamps is released in conjunction with the launch of the Fragile Forest and the 25th Anniversary of the Singapore Zoological Gardens.

Released together with these stamp booklets is a first day cover, incorporating the 10 stamps
