The first expedition discovered many rare and exotic flora and fauna, including a unique species of the Rafflesia flower, a large variety of orchids and many new species of insects, arachnids and molluscs, while the second expedition unearthed many more discoveries, with hundreds of species of plants, with more than 500 different species of moss, over 300 species of gymnosperms and flowering plants, 32 edible fruit trees and 21 species of ginger being catalogued.
Based on its findings, MNS concluded that Belum-Temenggor was home to some flora and fauna found nowhere else in the world and that species diversity was one of the richest in Malaysia, making conservation and proper land use imperative.
Convinced more than ever that Belum-Temenggor was in dire need of protection, MNS launched the ‘Belum-Temenggor Postcard Campaign’, calling upon the Perak State Government to gazette Belum-Temenggor. The campaign was a success, attracting over 80,000 signatures leading the Perak Government to officially gazette 117,500 hectares of the forest as the Royal Belum State Park, with logging in Belum-Temenggor to cease by 2008.
