Knowledge about the distribution and habitat preferences of a species is critical for its conservation. The Suweon Treefrog (Dryophytes suweonensis) is an endangered species endemic to the Republic of Korea. We conducted surveys from 2014 to 2016 at 890 potentially suitable sites across the entire range of the species in South Korea. We then assessed whether D. suweonensis was found in the current and ancestral predicted ranges, reclaimed and protected areas, and how the presence of…

Impact of Water Quality on the Occurrence of Two Endangered Korean Anurans: Dryophytes suweonensis and Pelophylax chosenicus
TLDR
Water contaminants play an important role in threatening amphibian species already in the midst of the sixth extinction and low conductivity in the water was correlated to the occurrence of P. chosenicus, and low ammonium nitrate was a reliable predictor for the existence of D. suweonensis.
Translocation of an endangered endemic Korean treefrog Dryophytes suweonensis
Endangered species in heavily modified landscapes may be vulnerable to extinction if no conservation plan is implemented. The Suweon treefrog Dryophytes suweonensis is an endemic endangered species
Update on Distribution and Conservation Status of Amphibians in the Democratic People’s Republic of Korea: Conclusions Based on Field Surveys, Environmental Modelling, Molecular Analyses and Call Properties
TLDR
It is argued 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.
Korean endemic species no more: on the occurrence of Pelophylax chosenicus in China
Understanding species distribution is the first requirement to work on their behaviour, conservation, and phylogeography. Over the last decades, the number of species described on the Korean
Large-Scale Hybridisation as an Extinction Threat to the Suweon Treefrog (Hylidae: Dryophytes suweonensis)
TLDR
A generalised, bi-directional, and geographically widespread hybridisation is revealed between the spatially restricted D. suweonensis and the widespread D. japonicus.
Preliminary Recommendations for National IUCN Red Listing Conservation Status of the “Dryophytes immaculatus group” in North East Asia

Recommendations for IUCN Red List Conservation Status of the “Dryophytes immaculatus Group” in North East Asia
Threat assessment is important to prioritize species conservation projects and planning. The taxonomic resolution regarding the status of the “Dryophytes immaculatus group” and the description of a
Policy Recommendation for the Conservation of the Suweon Treefrog (Dryophytes suweonensis) in the Republic of Korea
The Suweon treefrog (Dryophytes suweonensis) is an endangered species with an important evolutionary significance. However, the current rate of decline projects the extinction of the species within a
Climate change-based models predict range shifts in the distribution of the only Asian plethodontid salamander: Karsenia koreana
TLDR
An ecological model using six bioclimatic factors with low multicollinearity to define adequate habitat of K. koreana and modelled the predicted suitability of the Korean landscape following four Representative Concentration Pathways predicting climate change scenarios based on CO2 concentrations in 2050 and 2070 highlights the potential negative impact of climate change.
Distribution Change of Invasive American Bullfrogs (Lithobates catesbeianus) by Future Climate Threaten Endangered Suweon Treefrog (Hyla suweonensis) in South Korea
TLDR
This study modeled what environment the American Bullfrog settled in and how it could spread in the future and predicted changes in the potential distribution and future distribution based on climate change scenarios to analyze how those changes affect critically endangered Suwon treefrogs.

Seoul, Keep Your Paddies! Implications for the Conservation of Hylid Species
TLDR
This study demonstrates that neither habitat diversity nor surface area, but solely the occurrence of aggregated rice paddies is a requisite for H. suweonensis occurrence in metropolitan Seoul, and it is emphasized that the management plans therein can, and should, be used as the first step in the conservation of this species.
Description of a seminatural habitat of the endangered Suweon treefrog Hyla suweonensis
TLDR
The habitat characteristics of a seminatural site for H. suweonensis, a treefrog species endemic to Korea, have a large percentage of rice paddies with a very low percentage of urban areas, a feature consistent with findings of a previous study.

TLDR
The number of known populations increased by 60% and the known geographical range of the subspecies by approximately 30% and this study serves as a baseline for further ecological research and for conservation measures for one of the least known European viperid snakes.

Introduced bullfrogs are associated with increased Batrachochytrium dendrobatidis prevalence and reduced occurrence of Korean treefrogs
TLDR
The presence of L. catesbeianus can now be added to the list of factors responsible for the decline of D. suweonensis populations, and the endangered Dryophytes suwe onensis displays a significantly higher Bd prevalence than the more abundant D. japonicus.
