Determining the range, status, ecology and behaviour of species from areas where surveys and samplings are uncommon or difficult to conduct is a challenge, such as in the Democratic People’s Republic of Korea (DPR Korea). Here, we used genetic samples, field surveys, call recordings, photographic identification and a literature review to estimate the presence, range and status of amphibians in the DPR Korea. From our combined results and based on the IUCN Red List categories and criteria, we were able to estimate the national threat levels for most species. Our results demonstrated the presence of 18 native species and the suspected presence of Karsenia koreana and two Onychodactylus species. We reported the first record for Rana uenoi in the vicinity of Pyongyang using molecular tools and similarly confirmed the presence of Dryophytes japonicus at the same location. Based on distribution and modelling, we can expect the contact zone between species within the Rana and Onychodactylus genera to be located along the Changbai Massif, a mountain range that marks a shift in ecoregions and acts as a barrier to dispersion. The species richness was higher in the lowlands and at lower latitudes, with such areas populated by up to 11 species, while more northern regions were characterised by species richness of about half of that value. The combination of ecological models and known threats resulted in the recommendation of ten species as threatened at the national level following the IUCN Red List categories and criteria. This high number of threatened species was anticipated based on the high threat level to amphibians in bordering nations and globally. While the ecology of species in the DPR Korea is still understudied, we argue that species relying on agricultural wetlands such as rice paddies are not under imminent threat due to the enduring presence of extensive agricultural landscapes with low rates of chemical use and mechanisation. The maintenance of such landscapes is a clear benefit to amphibian species, in contrast to more industrialised agricultural landscapes in neighbouring nations. In comparison, the status of species dependent on forested habitats is unclear and threat levels are likely to be higher because of deforestation, as in neighbouring nations.

Snakebite envenomings remain a neglected disease across the globe causing severe injuries and death. An understanding of regional snakebite patterns is a necessary prerequisite for public health programs aimed at reducing snakebite risks. However, such regional knowledge is poorly documented or lacking in many countries where the risk of snakebite envenomings receive little medical attention, and the Republic of Korea is one of these countries. Here, we reviewed the literature on snakebites published between 1970 and 2020 as well as public healthcare data recorded between 2010 and 2019 to determine the patterns of snakebite envenomings in the Republic of Korea. Our results, based on literature data, show Gangwon province as a hotspot of snakebite occurrences and identify middle-aged males living in rural areas as the demographic group at highest risk of venomous snakebites. We also highlight major limitations for further understanding snakebite patterns in the country, most notably the lack of proper species identification for snakes and conflicting patterns of envenomings revealed by different sources of data. Our study provides baseline information on venomous snakebites occurring in the Republic of Korea, thereby filling a gap in the knowledge of snakebite trends in the country.

It is important to understand the dynamics of population size to accurately assess threats and implement conservation activities when required. However, inaccurate estimates are harming both the threat estimation process, and the resulting conservation actions. Here, we address the extinction threats to Scincella huanrenensis, a species described in the People’s Republic of China, but also occurring on the Korean peninsula. Estimating the threats to the species is not an easy task due to its unknown population status in the Democratic People’s Republic of Korea. Here we analysed the literature to acquire the known presence point for the species, along with datapoints originating from opportunistic field surveys, and employed habitat suitability models to estimate the range of the species. We then followed the categories and criteria of the IUCN Red List of Threatened Species to assess the extinction risk of the species. We found the species not to be fitting the threatened category at the global scale based on the range size, the only category for which enough data was available. We recommend the status of the species on the IUCN Red List of Threatened Species to be updated as it is now listed as critically endangered (CR), a listing fitting a national assessment for the People’s Republic (PR) of China. While this species is possibly less threatened than currently listed, this is not a genuine improvement, and specific conservation aspects should not be neglected due to its specialisation to medium to high elevation habitat.

The ecology of most squamates from the Republic of Korea is poorly understood: information on tolerances to environmental variables, movement patterns, home range sizes, and other aspects of their natural history and ecological requirements are lacking. In turn, this lack of knowledge presents an obstacle to effective conservation management. Currently and at the national level, two of Korea’s eleven terrestrial snake species are listed as threatened or near threatened: Elaphe schrenckii and Sibynophis chinensis, and one out of the six lizard species (Eremias argus) is listed as threatened. However, various threats including habitat loss, climate change and poaching may have already but unknowingly elevated other Korean reptiles to threatened statuses. To help resource managers in developing conservation programs, we provide a summary of the literature on threats to Korean squamates, a national recommended threat status, and species accounts focused on Korean populations. We recommend listing Hebius vibakari, E. argus, Scincella huanrenensis and Gekko japonicus under a higher threat level than the one provided by either the Korean National Institute of Biological Resources or the IUCN Red List. Our results highlight that conservation plans are urgently needed for Korean squamates, mostly because of habitat destruction, and that additional research has to be conducted on most species as there is a clear need for integrated ecological studies and active monitoring programs.

The herpetology collection of the Ewha Womans University Natural History Museum (EWNHM) represents one of the oldest and largest institutional collections in the Republic of Korea. The specimens deposited in the EWNHM represent a major historical collection of the native herpetofauna, both in species diversity and time span. However, the full inventory of the herpetology collection has never been conducted and thus the collection has received little attention from researchers. Here, the first full account of the herpetology specimens held at the EWNHM is provided, with voucher information for all documented specimens to make the collection accessible for future studies.
