Canting Expedition: Herpetofauna Diversity in the Mendolo Village, Lebakbarang, Pekalongan

Central Java is an area that has natural forests with quite high biodiversity potential, one of which is Mendolo Village, Lebakbarang, Pekalongan. The diversity of herpetofauna species is one of its potential biodiversity. Data collection on herpetofauna in Mendolo Village has not yet been carried out, even though this village is in direct contact with natural forests with great potential. The aim of this research is to reveal the diversity of herpetofauna types at this location. The method used is VES (Visual Encounter Survey). The data obtained was then analyzed using the Shannon-Wiener Diversity Index. There were 23 species of reptiles and 16 species of amphibians, with a Diversity Index value of 2.942 for reptile types and 2.28 for amphibians. The conclusion that can be drawn is that the diversity of herpetofauna species in Mendolo Village is in the quite high category.

Species Checklist and Diversity of the Herpetofauna of Tun Razak Agricultural Research Center, Pahang, Peninsular Malaysia

Herpetofauna represents a significant portion of global biodiversity. Understanding their distribution, ecology, and behavior is essential for conservation efforts. Many reptile and amphibian species are threatened or endangered due to habitat loss, pollution, climate change, and disease. A study was conducted to explore the herpetofauna in Tun Razak Agricultural Research Centre from 22 February 2023 to 17 March 2023 through Visual Encounter Survey (VES), covering four types of habitats; ponds, forest, oil palm and residential. A total of 23 species of herpetofauna were recorded, representing 14 amphibians and nine reptiles. Hylarana erythraea emerged as the most dominant species, followed by Fejervarya limnocharis. These species were found abundantly in ponds due to its suitability for breeding and ample food sources. The presence of these species indicates that the ecosystem has various habitat niches. Most of the species found were globally classified as Least Concern. However, the survey also recorded Ophiophagus Hannah and Cuora amboinensis, listed as Vulnerable and Endangered respectively. The study highlighted the importance of clean water in ponds for frog breeding, as it ensures proper oxygenation and minimizes exposure to harmful substances. Furthermore, the study demonstrated the potential of herpetofauna as a bioindicator, with changes in their populations reflecting environmental changes or disturbances. The species rank abundance curves showed that the oil palm habitat exhibited the highest species evenness, suggesting a balanced distribution of species within the ecosystem. However, further surveys are needed in the area to determine the full extent of herpetofauna composition. Overall, the findings emphasise the necessity of preserving various habitats to support herpetofauna populations while also maintaining ecosystem health and balance for human-animal coexistence.

New species of Gehyra (Squamata: Gekkonidae) from Papua New Guinea

I describe four new species of Gehyra from New Guinea and immediately adjacent islands. Two of these are giant species that have long been misassigned to either G. vorax or G. membranacruralis; the other two were previously referred to G. oceanica. Each of the new species has a very circumscribed geographic distribution, with one being known from only a single island, a second from a small portion of southeastern New Guinea and immediately adjacent islands, a third from a small archipelago, and the fourth from foothill forest along the northern versant of eastern New Guinea. Three of these species are found only in the Milne Bay Region of southeastern Papua New Guinea, a region previously identified as having a globally high density of narrow-range endemic reptile and amphibian species. These species provide further extension of that pattern by increasing the number of known endemic herpetofaunal species from that small region to 165. Variation in subcaudal shape is taxonomically useful in Gehyra, but its character-state coding must rely on original tails because aberrant development of subcaudals in some regenerated tails could lead to mischaracterization of this feature.

Scale of unregulated international trade in Australian reptiles and amphibians.

Reptiles and amphibians are popular in the exotic pet trade, where Australian species are valued for their rarity and uniqueness. Despite a near-complete ban on the export of Australian wildlife, smuggling and subsequent international trade frequently occur in an unregulated and unmonitored manner. In 2022, Australia listed over 100 squamates in Appendix III of the Convention on International Trade in Endangered Species of Wild Fauna and Flora (CITES) to better monitor this trade. We investigated current trade and assessed the value of this Australian CITES listing using web-scraping methods to monitor the online pet trade in Australian reptiles and amphibians, with additional data from published papers, trade databases, and seizure records. Despite the export ban, we identified 170 endemic herpetofauna (reptile and amphibian) species in international trade, 33 of which were not recorded previously in the international market, including 6 newly recorded genera. Ninety-two traded species were included in CITES appendices (59 added in 2022), but at least 78 other traded species remained unregulated. Among these, 5 of the 10 traded threatened species were unlisted, and we recommend they be considered for inclusion in CITES Appendix III. We also recommend the listing of all Diplodactylidae genera in Appendix III. Despite this family representing the greatest number of Australian species in trade, only one genus (of 7 traded) was included in the recent CITES amendments. Overall, a large number of Australian reptile and amphibian species are traded internationally and, although we acknowledge the value of Australia's recent CITES listing, we recommend the consideration of other taxa for similar inclusion in CITES.

What are we saving? The amphibians and reptiles of the rice paddies in the Balasore District, Odisha, India

Agriculture is widely recognized as one of the major conservation threats to herpetofaunal species. Any conservationactions, particularly those aimed at herpetofauna beyond the network of protected areas, require baseline dataon existing species diversity in an area. Unfortunately, most biodiversity studies are focused on producing inventoriesof animals in a small number of protected areas. To accrue truly meaningful benefits, conservation needs to focus onhuman-dominated landscapes beyond protected areas, such as agricultural lands. Scientific documentation of farmlandherpetofauna is entirely lacking, which could lead to a lack of management and effective inclusion of herpetofaunain conservation. I assessed the species of amphibians and reptiles in tropical rice paddies near the Kuldiha WildlifeSanctuary in Balasore District, Odisha, India. Based on ecological sampling and community interviews, combined withliterature reviews and field guides, I report a total of 55 species including 16 species of amphibians in five families and39 species of reptiles in 15 families.

CATATAN LAPANGAN MENGENAI SATWALIAR DI LOKASI EKOWISATA SYURGAR SAUSAPOR, KABUPATEN TAMBRAUW

This study was conducted at Syurgar ecoutourism site, subdistrict of Sausapor Tambrauw district. Data was collected from June to July 2020 using survey method, direct catching, cage trap and interview. This study aimed to list the wildlife species, especially Birds, Mammals Herpetofauna, and Butterflies in order to complete data of the government of Tambrauw District for the purpose of Syurgar ecotourism development. This study recorded that there were 15 birds’ species of 13 families, 12 mammals’ species of 6 family, 4 herpetofauna’s species of 4 families, and 25 butterflies of 4 families. Syurgar has a potential to be a birdwatching site. There are several appealing birds, including Lesser bird-of-paradise (Paradisaea minor), king bird of paradise (Cincinurus regius), blyth’s hornbill (Rhyncetores plicatus), sulphur-crested cockatoo (Cacatua galerita). Endemic species of mammals include long-beaked echidna (Zaglosus bruijnii), dorcopsis/forest’s wallaby (Dorcopsis sp.), northern common cuscus (Phalanger orientalis), common spotted cuscus (Spilocuscus maculates), old world fruit bats (Dobsonia sp.), great flying fox (Pteropus neohibernicus). Endemic species of herpetofauna include frogs (Papurana sp.), Papua wrinkled ground frog (Cornufer papuensis). Eventually, some butterflies’ species include redeye bushbrown (Mycalesis aethiops), bushbrown (Mycalesis elia), and Papuan gull (Cepora abnormis). It is strongly suspected that several birds, mammals, herpetofauna, and butterflies have not been recorded due to time constraints. Therefore, further study is recommended for data completion.

Species richness, composition, distribution and conservation status of herpetofauna in a global hotspot: The Mountains of Southwest China

Herpetofauna have attracted considerable global attention due to their high risk of extinction. The Mountains of Southwest China are among the 36 global biodiversity hotspots due to their high biodiversity and irreplaceability, and the Shaluli Mountains are the core area of this region. However, the diversity and conservation status of herpetofauna in the Shaluli Mountains remain unclear. In this study, we updated the species richness and composition information of herpetofauna in the Shaluli Mountains based on extensive field expeditions, published literature, and museum specimens. In addition, we identified the local hotspots and key environmental factors limiting species distribution using environmental niche models (ENMs). Furthermore, we evaluated the conservation status of the key species via the Red List Index and gap analysis. Our results revealed a total of 68 herpetofauna species, representing 30 amphibians (21 genera in nine families) and 38 reptiles (19 genera in six families). The amphibian richness showed a hump-shaped pattern along the elevational gradient, while the reptile richness showed a monotonically decreasing pattern. The dry-hot river valley was identified as a local hotspot, and the key environmental factors limiting the richness of herpetofauna species differed. Moreover, the regional Red List indices for amphibians and reptiles were 0.87 and 0.8, respectively, showing that the overall threat level of this region was low. However, there are large conservation gaps in the protection of key species. Our study indicated that new protected areas should be established and the existing protected areas should be upgraded to protect herpetofauna with a large conservation gap.

Non-native herpetofauna of Aruba island (Caribbean): patterns and insights

Islands harbor a significant proportion of global biodiversity and also have disproportionately high richness of introduced species relative to continents. Given the sensitivity of island ecosystems to introduced species, data deficiencies on introduction pathways, patterns of establishment, and potential impacts of introduced species can hamper mitigation and conservation efforts on islands. The Caribbean region is emerging as a hotspot for introduced amphibian and reptile (herpetofaunal) species, but patterns associated with herpetofaunal introductions on specific islands are not well explored. Here, we perform a detailed investigation of Aruba, a small Caribbean island with an exceptionally high number of introduced herpetofaunal species. We compile a database from the literature of introduction pathways, introduction years, source locations, native ranges, establishment outcomes, habitat use, and ecological impacts for three newly documented species and the 12 previously documented introduced herpetofaunal species on Aruba. From this database we synthesize emergent introduction patterns on Aruba and highlight areas of data deficiency. Overall, the patterns on Aruba echo the patterns exhibited in the greater Caribbean region. Introduction rates on Aruba have been increasing exponentially, yet the introduction pathways and source locations of most species are unknown. Following introduction, most species successfully establish localized populations in anthropogenic habitat, but the ecological impacts of most species have not been well-assessed. We suggest increased monitoring of shipments will help identify potential pathways to slow the introduction of new species, and further studies of ecological impacts of introduced species are needed.

Herpetofauna of Laguna Blanca National Park, Argentinean Patagonia: species list and conservation status

Laguna Blanca National Park (LBNP) is located in the mid-west of Neuquén Province, Argentina. It was created in 1940 with the aim of conserving the nesting and breeding habitats of an important diversity of birds. Until now, there have been no exclusive works that address the herpetofauna present. The aim of this article is to provide an updated inventory of reptile and amphibian species in LBNP. We used four sources of information to create the species list: 1) data coming from field observations; 2) specimens deposited in herpetological collections; 3) scientific literature review; 4) online biodiversity databases. We confirm the occurrence of 18 species of herpetofauna in LBNP, including 13 reptiles and 5 amphibians. We also included six species with probable presence according to the range of distribution and habitat similarity. We added the conservation status of the national and international lists for each species. Five species are in some threat category at the national (Vulnerable, Endangered) or international level (Endangered, Critically Endangered). Seven taxa are listed as “Species of Vertebrates of Special Value” by the Administración de Parques Nacionales. Despite being protected within a national park, the herpetofauna present face threats such as prolonged drought events, habitat modification due to the presence of livestock, introduced exotic species, and emerging diseases. Conservation efforts are imperative to protect these species and mitigate their threats.

Short Communication: A rapid survey of herpetofauna diversity in Bama coastal forest at Baluran National Park, Indonesia

Abstract. Siddiq AM, Wimbaningrum R, Sulistiyowati H, Setiawan R, Setiawan A, Wahono ND. 2024. Short Communication: A rapid survey of herpetofauna diversity in Bama coastal forest at Baluran National Park, Indonesia. Biodiversitas 25: 2323-2329. Scientific reports on herpetofauna in Baluran National Park (BNP) are still limited. Meanwhile, several geographical areas, such as the Bama Baluran National Park coastal forest, have potential herpetofauna diversity within this conservation area yet to be reported. Therefore, this study aimed to determine the diversity of herpetofauna species in BNP's Bama coastal forest (BCF). The method was conducted using the Visual Encounter Survey (VES) in three tracks, conducted by combining Time Restricted Search (TRS) or using observation time for five hours during the mid-afternoon (06.00 AM-11.00 AM) and four hours at night (07.00 PM-11.00 PM) on each track. This study recorded 17 herpetofauna species, comprising 6 amphibian and 11 reptile species, in the BCF of Baluran National Park. The diversity index of herpetofauna species in this area was moderate category (H’=2.25). Species Fejervarya limnocharis Gravenhorst 1829 (38 individuals) has the highest abundance in the BCF and was found in track 1 (swamp area). Meanwhile, three species have the lowest abundance, such as Kaloula baleata Müller 1836, Microhyla palmipes Boulenger 1897, and Cryptoblepharus balinensis Barbour 1911, with 1 individual in each species.

Spatiotemporal Patterns of Reptile and Amphibian Road Fatalities in a Natura 2000 Area: A 12-Year Monitoring of the Lake Karla Mediterranean Wetland.

The pervasive expansion of human-engineered infrastructure, particularly roads, has fundamentally reshaped landscapes, profoundly affecting wildlife interactions. Wildlife-vehicle collisions, a common consequence of this intricate interplay, frequently result in fatalities, extending their detrimental impact within Protected Areas (PAs). Among the faunal groups most susceptible to road mortality, reptiles and amphibians stand at the forefront, highlighting the urgent need for global comprehensive mitigation strategies. In Greece, where road infrastructure expansion has encroached upon a significant portion of the nation's PAs, the plight of these road-vulnerable species demands immediate attention. To address this critical issue, we present a multifaceted and holistic approach to investigating and assessing the complex phenomenon of herpetofauna road mortality within the unique ecological context of the Lake Karla plain, a rehabilitated wetland complex within a PA. To unravel the intricacies of herpetofauna road mortality in the Lake Karla plain, we conducted a comprehensive 12-year investigation from 2008 to 2019. Employing a combination of statistical modeling and spatial analysis techniques, we aimed to identify the species most susceptible to these encounters, their temporal and seasonal variations, and the ecological determinants of their roadkill patterns. We documented a total of 340 roadkill incidents involving 14 herpetofauna species in the Lake Karla's plain, with reptiles, particularly snakes, being more susceptible, accounting for over 60% of roadkill occurrences. Moreover, we found that environmental and road-related factors play a crucial role in influencing roadkill incidents, while spatial analysis techniques, including Kernel Density Estimation, the Getis-Ord Gi*, and the Kernel Density Estimation plus methods revealed critical areas, particularly in the south-eastern region of Lake Karla's plain, offering guidance for targeted interventions to address both individual and collective risks associated with roadkill incidents.

Herptile gut microbiomes: a natural system to study multi-kingdom interactions between filamentous fungi and bacteria.

Reptiles and amphibians (herptiles) are some of the most endangered and threatened species on the planet and numerous conservation strategies are being implemented with the goal of ensuring species recovery. Little is known, however, about the gut microbiome of wild herptiles and how it relates to the health of these populations. Here, we report results from the gut microbiome characterization of both a broad survey of herptiles, and the correlation between the fungus Basidiobolus, and the bacterial community supported by a deeper, more intensive sampling of Plethodon glutinosus, known as slimy salamanders. We demonstrate that bacterial communities sampled from frogs, lizards, and salamanders are structured by the host taxonomy and that Basidiobolus is a common and natural component of these wild gut microbiomes. Intensive sampling of multiple hosts across the ecoregions of Tennessee revealed that geography and host:geography interactions are strong predictors of distinct Basidiobolus operational taxonomic units present within a given host. Co-occurrence analyses of Basidiobolus and bacterial community diversity support a correlation and interaction between Basidiobolus and bacteria, suggesting that Basidiobolus may play a role in structuring the bacterial community. We further the hypothesis that this interaction is advanced by unique specialized metabolism originating from horizontal gene transfer from bacteria to Basidiobolus and demonstrate that Basidiobolus is capable of producing a diversity of specialized metabolites including small cyclic peptides.IMPORTANCEThis work significantly advances our understanding of biodiversity and microbial interactions in herptile microbiomes, the role that fungi play as a structural and functional members of herptile gut microbiomes, and the chemical functions that structure microbiome phenotypes. We also provide an important observational system of how the gut microbiome represents a unique environment that selects for novel metabolic functions through horizontal gene transfer between fungi and bacteria. Such studies are needed to better understand the complexity of gut microbiomes in nature and will inform conservation strategies for threatened species of herpetofauna.

First documentation on herpetofauna diversity in Gunung Belumut Amenity Forest, Peninsular Malaysia: Implications for conservation in an Environmentally Sensitive Area (ESA).

Malaysia is blessed with lush tropical rainforests that harbour an exceptional diversity of amphibians and reptiles. However, compared to other animal groups, amphibians and reptiles have received limited attention in research, despite their ecological significance. With amphibians and reptile species having been declining rapidly due to anthropogenic activities, there is a pressing need to conserve these species and their habitats. Environmentally Sensitive Areas (ESAs) are designated regions that are beneficial due to their critical role in providing essential ecosystem services and serving as repositories of biodiversity. Nonetheless, the classification of ESAs in Malaysia lacks biological elements and only focuses on physical attributes. To enhance the current ESA classification framework by integrating biological components, there is an urgent need to obtain information on diversity and habitat in Malaysia. Therefore, the objectives of this study were twofold: to determine the diversity of amphibians and reptiles in Gunung Belumut Amenity Forest and to conduct a comparative analysis between the herpetofauna assemblages in Gunung Belumut with other forest reserves in Peninsular Malaysia. The survey was carried out between March and June 2022, with additional sampling conducted in February 2023. The Visual Encounter Survey (VES) and pitfall trap methods were employed to survey the herpetofauna species, focusing on both aquatic and terrestrial habitats within the study area. A total of 210 individuals representing 38 species of herpetofauna were recorded, comprising 18 amphibian and 20 reptile species. Amongst the observed species, Limnonectesblythii was the most frequently encountered amphibian, with 59 individuals observed, while the dominant reptile species was Cyrtodactylusconsobrinus, represented by eight individuals. This pioneering study serves as a vital baseline documentation of the amphibian and reptile assemblages in Gunung Belumut Amenity Forest. It provides valuable information for identifying extant herpetofauna species, including those of potential conservation concern or rarity. These findings contribute to ongoing conservation efforts dedicated to the preservation of herpetofauna within the region. By understanding the diversity and distribution patterns of amphibians and reptiles in Gunung Belumut, effective conservation strategies can be developed to protect these species and their habitats.

The impact of Eucalyptus plantations on herpetofaunal diversity, Maputo National Park, Mozambique

ABSTRACT Exotic afforestation has proven detrimental to biodiversity in general, however only a few studies documenting the impact of timber plantations on herpetofaunal diversity have been published within a southern African context. To determine if variations in herpetofaunal species assemblages could be detected between derelict Eucalyptus plantations, cleared plantation woodlots, and untransformed sand thicket vegetation, a pitfall and funnel trap survey was conducted in coastal southern Mozambique. Herpetofaunal species richness for derelict Eucalyptus plantations was 13 ± 2.24 species, untransformed sand thicket vegetation 17 ± 2.34 species and cleared plantation woodlots 18 ± 3.14 species. Both Shannon-Weaver and Simpson Diversity Indices estimated the highest herpetofaunal species diversity in untransformed sand thicket vegetation and the lowest diversity in derelict Eucalyptus plantations. The herpetofaunal species assemblages of derelict Eucalyptus plantations and natural sand thicket vegetation were least similar (0.507 ± 0.041), while cleared plantation woodlots and derelict Eucalyptus plantations were most similar (0.753 ± 0.032) in terms of herpetofaunal community composition. In contrast to our expectations, significantly higher capture rates were reported for a fossorial anuran in derelict Eucalyptus plantations compared to both cleared plantation woodlots and untransformed sand thicket vegetation, which requires further investigation and discussion. As with most other studies investigating the effects of exotic timber plantations on biodiversity, our results indicate that the detectable herpetofaunal diversity decreased in Eucalyptus plantations when compared to natural or cleared plantation woodlots. Subsequently it would seem as though the active clearing of dilapidated timber plantations as part of rehabilitation efforts may positively affect herpetofaunal diversity.

Inventario de la Herpetofauna de México 2023

For the Inventory of the Herpetofauna of Mexico, a total of 1,422 native herpetofaunal species are reported so far (892 endemic, 62.7%), of which 430 (30.2%) are amphibians (15 families and 58 genera) with 299 (69.5%) endemic species, and 992 (69.8%) reptiles (41 families and 154 genera) with 593 (59.8%) endemic species.

Wetland biodiversity of Ramaroshan Lake complex: a need for conservation

The Ramaroshan Lake Complex, situated in the mid-hills of Sudurpaschim Province, is renowned for its scenic beauty, yet there is a notable dearth of information regarding its biodiversity and ecological status. This study represents the first systematic examination of seasonal variations in water quality parameters and biodiversity encompassing aquatic macroinvertebrates, fishes, birds, herpetofauna, mammals, and macrophytes, as well as the surrounding vegetation within the complex, spanning the winters and summers of 2018 and 2019. Among the twenty water quality parameters investigated, thirteen displayed significant seasonal differences across the lakes (p <0.05), with Batula and Ramaroshan lakes exhibiting elevated nutrient levels. Lamadaya Lake stood out with a highly diverse macroinvertebrate community compared to other lakes, while overall, the study recorded 45 aquatic macroinvertebrate families, three fish species, 79 bird species, 12 herpetofauna species, 12 mammal species, and 26 macrophyte species within the complex. Additionally, the surrounding vegetation comprised 193 distinct plant species. Notably, the complex currently hosts 14 IUCN Red List species, including Near Threatened (5), Vulnerable (5), Critically Endangered (1), and Endangered (3) species, as well as five migratory wetland bird species, underscoring its significance for wildlife conservation. Given the diverse and cross-cutting nature of wetlands, the development of science-based policies and coordinated efforts among central, provincial, and local governments are essential for the preservation and sustainable management of these vital ecosystems.

Inventory of Herpetofauna in the Buffer Zone of Mt. Hamiguitan Range Wildlife Sanctuary, San Isidro, Davao Oriental, Philippines

The Mount Hamiguitan Range Wildlife Sanctuary (MHRWS) is a declared national park and a wildlife sanctuary located in the province of Davao Oriental in the Philippines. Most of the herpetofauna surveys conducted in the MHRWS were located in the protected areas of the mountain. Thus, this study was done to assess the surrounding buffer zone in the northwestern part of the mountain as a crucial step toward enhancing conservation and management policies for these taxa and reinforcing the importance of buffer zones as protective barriers around the core zones. Standard sampling technique for herpetofauna survey such as the cruising method in a 1-km transect line per study area was used. Pitfall trapping was also employed for reptile fauna. A total of 25 species of herpetofauna were documented in the survey, 10 species of which are anurans and 15 species are reptiles. The majority of the species documented are endemic to the Philippines. Moreover, threatened and near-threatened species were also observed in these areas. This only shows the importance of buffer zones in providing habitats to diverse herpetofauna aside from the core zones. Hence, proper conservation and sustainable practices shall be planned in order to maintain the biodiversity in the area while also serving the people in the nearby community.

Herpetofauna Diversity at Eaglewood Gyrinops vesteegii Conservation Area in Pusuk Protected Forest, Lombok

Pusuk Protected Forest at Lembah Sari Village, Batu Layar District, western Lombok is Gyrinops vesteegii conservation area, the one of eaglewood trees in the Lesser Sunda Islands. Studying diversity and distribution of herpetofauna in conservation area to understanding how this fauna could be stabilized the community structure of organisms in the ecosystems with their act as secondary and tertiary consumers in food web organization. Herpetofauna in this area was captured by visual encounter surveys (VES) method. Eleven species of herpetofauna have been collected from eaglewood conservation area in protected forest of Pusuk, is comprised by four species of amphibians (Duttaphrynus melanostictus, Ingerophrynus biporcatus, Limnonectes dammarmani and Limnonectes kadarsani) and seven species of reptiles (Ahaetulla prasina, Cyrtodactylus petani, Dendrelaphis pictus, Draco volans, Eutropis multifasciata, Gekko gecko, Sphenomorpus melanopogon and Sibynopis geminatus). This animal group plays as a role in maintaining the stability of eaglewood ecosystems by controlling its pest populations such as moth larvae of Heortia vitessodes and white lice of Dysmicoccus brevipes. Based on this research, higher diversity of herpetofauna with varying types of their habitats could be control the varying types of forest tree pests

Herpetological Collections in the Thailand Natural History Museum as a Valuable Resource for Conservation and Education

The history of collecting and cataloging Thailand’s diverse herpetofauna is long-standing, with many specimens housed at the Thailand Natural History Museum (THNHM). This work aimed to assess the diversity of herpetofauna within the THNHM collection, ascertain conservation status of species, and track the geographical coverage of these specimens within the country. The THNHM collection boasts an impressive inventory, numbering 173 amphibian species and 335 reptile species. This collection reflects the substantial biodiversity within these taxonomic groups, rivaling the total number of herpetofauna species ever recorded in Thailand. However, the evaluation of their conservation status, as determined by the IUCN Red List, CITES, and Thailand’s Wild Animal Preservation and Protection Act (WARPA), has unveiled disparities in the degree of concern for certain species, possibly attributable to differential uses of the assessment criteria. Notably, the museum houses a number of type specimens, including 27 holotypes, which remain understudied. Sampling efforts have grown considerably since the year 2000, encompassing nearly all regions of the country. This extensive and systematic collection of diverse herpetofauna at the THNHM serves as a valuable resource for both research and educational purposes, enriching our understanding of these species and their significance in the broader context of biodiversity conservation.
