SANDAKAN: Pitcher plants are Sabah’s natural heritage and should be given priority in research and conservation, pointed out by the Chief Conservator of Forests, Datuk Frederick Kugan.
“Research undertaken by Sabah Forestry Department focuses on biodiversity preservation, understanding threats, and developing conservation strategies and is the backbone of informed decision-making in plant conservation and ensures that efforts are scientifically grounded and effective, in line with the Sabah Forest Policy 2018,” said Kugan.
The Forest Biodiversity and Conservation Programme under the Forest Research Centre (FRC) in Sepilok, headed by John Sugau, has been spearheading plant research and conservation in Sabah, with the Sandakan (SAN) Herbarium as a significant scientific reference collection, led by Dr Joan Pereira. Alviana Damit is the key FRC researcher, working on pitcher plants, collaborating with various local and international experts on this subject.
Scientifically known as Nepenthes, pitcher plants are a genus of carnivorous plants with over 160 known species worldwide, 25 of which can be found in Sabah. These extraordinary plants are extremely popular and have captivated nature enthusiasts globally due to their unique ‘cup’ structures that ‘eat’ insects and small animals.
The pitchers vary in colour, shape, and size, ranging from as small as 5 centimetres to a remarkable 45 centimetres. Nepenthes species exhibit diverse growth forms as climbing vines, shrubs, or epiphytes that grow on the ground, on rocks, or even attached to trees. Certain species can also grow abundantly, colonizing an area and forming a dense ‘carpet’ of pitchers scrambling across the ground or a ‘curtain’ of pitchers hanging from trees, creating an enchanting forest landscape.
“Eight of Sabah’s 25 species are endemic to the region. The state’s diverse landscapes, ranging from tropical rainforests to montane habitats, provide ideal conditions for these plants. Many scientists consider Sabah’s Nepenthes species among the most iconic and well-characterized worldwide. The world’s largest pitcher plant, Nepenthes rajah, is only found in Mount Kinabalu and its surrounding highlands. The pitcher is capable of storing up to 3.5 litres of liquid.
“This species has been observed to trap not just insects but even small mammals like rats,” Kugan said.
Despite their remarkable adaptations, many of Sabah’s pitcher plants face threats that affect their survival. Seven Nepenthes species in Sabah are currently listed as threatened on the IUCN Red List. Most of these are montane species with very limited distribution, such as N. rajah, N. edwardsiana and N. macrophylla, which are restricted to single mountain ranges.
As these plants are facing increasing threats, the urgency for conservation grows. By protecting their habitats, promoting sustainable practices, and supporting scientific research, we can ensure the survival of these botanical wonders for generations to come. Collaboration among conservationists, researchers, local communities, and policymakers is key to safeguarding Sabah’s pitcher plants as symbols of the state’s rich biodiversity and ecological heritage. In short, protecting Sabah’s pitcher plants requires collective and collaborative actions.
