Vital to save M'sia's diverse flora
These species, which comprise flowering plants and trees, are under threat due to poaching and other human activities, says Sabah Forestry Department director Datuk Frederick Kugan.
'Besides pitcher plants, the other types of flora facing threats are trees and flowers,' he said.
Kugan cited examples such as the dipterocarp (timber) which are being logged and harvested while high horticultural demand for exotic plants like pitcher plants and orchids means they are poached in the wild and sold in the black market.
'There is also habitat loss due to plantation expansion,' he said.
He also spoke about a small distribution pattern which is being threatened by climate change, especially montane (mountainous) species, adding that this has also contributed to the decline of such species.
Overall, he said, the species are categorised as 'threatened' under the International Union for Conservation of Nature (IUCN) list.
The 'threatened' category is further divided into CR (critically endangered), EN (endangered) and VU (vulnerable).
In fact, Kugan said that 10 species of CR plants had been marked as possibly extinct – anisophyllea impressinervia, ixora labuanensis, lasianthus subglobosus, melanochyla woodiana, praravinia gracilis, praravinia neriifolia, quercus pseudoverticillata, semecarpus angulatus, semecarpus sandakanus and syzygium badescens.
The last seen photos of these tree species ranged from 45 to 148 years ago, Kugan said.
'Another possibly extinct species that was part of our conservation project for the last few years is the CR elaeocarpus pinosukii',' he said.

He said that many search operations were mounted to locate this species at its locality, Pinosuk Plateau or Mesilau in Kundasang, but none had been found.
Kugan said Pinosuk Plateau or Mesilau, as it is known today, is no longer a forest like it was 60 to 70 years ago (when the species was first collected) as most of these areas have been turned into vegetable farms.
He said all these assessments are based on what have been published in the IUCN Red List.
'However, we have thousands of species that have not been assessed yet, especially the non-tree species,' he added.
Kugan said that more research and conservation initiatives need to be taken to better protect these species and hopefully, prevent their extinction.
'There must be coordinated efforts between state agencies, private sectors as well as local communities to find solutions on how to reduce impact on flora and fauna with the development that is taking place,' he said.
In March, Kugan revealed that the pitcher plant is under threat in Sabah, with seven species listed as threatened on the IUCN list.
Pitcher plants, also known as monkey cups, have over 160 species worldwide, out of which 25 are found in Sabah.
The world's largest pitcher plant, nepenthes rajah, is only found in Mount Kinabalu and its surrounding highlands.
This species can trap not just insects but also small mammals like rats.
An AFP report in March quoting the IUCN said that 'deforestation, farming and climate-fuelled fires are driving increasing threats to fungi, the lifeblood of most plants'.
At least 411 fungi face extinction out of the 1,300 varieties, said IUCN's Red List of Threatened Species.

Eurasian otter spotted in Sabah
Rare sighting: Camera trap photos of the Eurasian otter captured at a riverbank at the Tangkulap Forest Reserve. — Photo courtesy of the Sabah Forestry Department/Sabah Wildlife Department/Panthera PETALING JAYA: The rare exclusive Eurasian otter has been sighted again – 11 years after its last confirmed appearance in Sabah. Once thought to be possibly eradicated from Malaysia, the Eurasian otter at the Tangkulap Forest Reserve in Sabah was captured on camera trap photos by Panthera, a conservation group studying wild cats. Project coordinator for Panthera Malaysia Tee Thye Lim said the last confirmed sighting of the Eurasian otter in Malaysia was in 2014, specifically near the Danum Valley Field Centre in Sabah. In contrast to Tangkulap Forest Reserve, which was previously a logged forest, the Danum Valley forest is relatively undisturbed. 'Historically, there has been little evidence confirming the presence of the Eurasian otter in Malaysia. 'This lack of records may partly be due to difficulties in distinguishing them from other otter species in the region, as well as a limited number of camera trap studies focused on wetlands,' he said in an e-mail interview. Overall, the Eurasian otter (Lutra lutra) is considered a rare species across Malaysia, he added. With this sighting, Tangkulap is now the only known location in Malaysia where all four native otter species coexist – the smooth coated otter, the Asian small-clawed otter, the hairy-nosed otter and the Eurasian otter. The Eurasian otter has been assessed as 'Near threatened' under the International Union for Conservation of Nature (IUCN) Red List of Threatened Species in 2020. Panthera works in this region to conduct monitoring surveys, determine population numbers of small cat species, and understand how they are affected by logging, agricultural expansion and poaching. However, to a question about whether the sighting could be due to an improvement in river and water quality in Tangkulap, Tee said: 'At this stage, we haven't had the opportunity to establish the kind of long-term environmental monitoring data that would allow us to make assumptions or pinpoint direct ecological impacts.' He said the Tangkulap Forest Reserve has suffered significant degradation over the past 20 years due to widespread logging, with all logging licences officially revoked in 2003. 'The recent discovery of all four otter species within this reserve indicates the success of the Forest Management Plan developed by the Sabah Forestry Department for this area,' said Tee. As the only location in Malaysia known to support all four of the country's otter species, this distinction alone emphasises its great ecological importance and confirms its role as a key conservation priority, he said. However, Tee cautioned that despite this remarkable biodiversity, aquatic habitats essential for otters and flat-headed cats are often under-represented in standard camera trap studies. 'This is mainly due to inherent challenges such as frequent flooding and the resulting equipment loss. 'While we recognise the strong link between these aquatic apex predators and good water quality, broader landscape-level threats remain unaddressed,' he said, adding that human activities, including illegal fishing, habitat encroachment, hunting and agricultural water pollution, pose significant risks that could lead to the extinction of these aquatic-dependent species. 'At the same time, our understanding of their movement ecology in wet environments is still limited, leaving our knowledge of these vital species incomplete,' he said. To ensure the success of truly effective conservation efforts, Malaysia's immediate focus, he said, must be to thoroughly identify and understand the specific threats facing these aquatic top predators in this particular landscape. 'This essential knowledge will be key in developing targeted and impactful conservation strategies.'

We need more experts in plant biodiversity, says academician
PETALING JAYA: Amid multiple threats to the survival of plant species in Malaysia, the country is facing a lack of experts to work on biodiversity, says Malaysian Ecological Association president Prof Dr Ahmad Ismail. There is an inadequate number of experts in this field, he said. He said this problem is rooted in the lack of funds to support research and development of new talents in the field of biodiversity. 'When we don't have enough people and money, it would also be difficult to do research, especially biodiversity work mostly in the field,' he said. Prof Ahmad added that while regional estimates report about 8,300 vascular plant species in Peninsular Malaysia and around 12,000 in Sabah and Sarawak, the national total is estimated at 15,000 due to significant species overlap across regions. 'For example, Mount Kinabalu in Sabah alone has recorded over 5,000 plant species, with 40% being endemic. 'This is about the richness of plants in Malaysia. But those are mostly old data that were studied by foreign scientists. "If we ratio plant species with our local botanists, the number is very low,' he said, urging for more to be done in recruiting young talents in biodiversity conservation. He also pointed out that while laws exist to protect Malaysia's natural resources, the lack of research and experts is concerning, especially given the country's uniquely diverse plant life. According to the International Union for Conservation of Nature (IUCN) Red List, from 1998 until 2025, a total of 193 plant species in Malaysia were categorised as critically endangered, 423 as endangered and 841 as vulnerable. The Malaysia Biodiversity Information System (MyBIS) database showed that at least 138 plant species in Peninsular Malaysia were identified as critically endangered, vulnerable or endangered. Among the critically endangered plant species are mersawa merah (anisoptera megistocarpa), berus mata buaya (bruguiera hainesii), keruing pipit (dipterocarpus fagineus) and merawan mata kuching merah (hopea ferruginea). Endangered species include bearded paphiopedilum (paphiopedilum barbatum), keladan (dryobalanops oblongifolia) and keruing bukit (dipterocarpus costatus). In the vulnerable category are chengal (neobalanocarpus heimii), agarwood (aquilaria malaccensis) and meranti pa'ang (shorea bracteolata). MyBIS is a one-stop repository database system, which provides and facilitates access to information on biodiversity studies and management in Malaysia under the Natural Resources and Environmental Sustainability Ministry. The data collection in MyBIS involved experts and research officers from government agencies, non-governmental organisations, research institutes and universities. Sahabat Alam Malaysia (SAM) president Meenakshi Raman said that deforestation and uncontrolled conversion of areas for commercial development continue to threaten the survival of plant species in Malaysia. She warned that if the forests are not protected, the important plant species will be gone forever. 'We have a National Biodiversity Policy and national biodiversity action plans but they mean nothing if they are not implemented with legal effectiveness and protection. 'States have the power to designate areas and forests to protect species but they often sacrifice them for timber, plantations and other commodities on the grounds that these are for income,' she said.

Vital to save M'sia's diverse flora
KOTA KINABALU: The plant kingdom isn't doing so well with at least 600 species facing extinction in Sabah alone. These species, which comprise flowering plants and trees, are under threat due to poaching and other human activities, says Sabah Forestry Department director Datuk Frederick Kugan.
