“…To determine the habitat variables, we conducted a literature review on P. hallaisanensis with a specific focus on the associated spatial factors (habitat distribution and condition), climate, topography (slope, direction, and altitude), threats, and soil factors (acidity, organic content, electrical conductivity, total nitrogen, and exchangeable cations) to derive five environmental factors that influence P. hallaisanensis habitats (Table 1) (Cho and Choi 2011;Kim et al 2016;Kim et al 2018;Kim et al 2019;You et al 2013).…”

“…Results from our literature review and consultations with experts in the field indicated that P. hallaisanensis habitats are primarily distributed in subalpine zones at high altitudes (Kim et al 2018;Korea National Park Research Institute 2016;You et al 2013). Thus, we used a warmth index to distinguish between different vegetation zones (Table S1).…”

“…Considering the characteristic distribution of P. hallaisanensis in subalpine zones, where climate change has a relatively strong impact (Kim et al 2018), we identified temperature as having a significant influence on the distribution of P. hallaisanensis. We used the average annual temperature to include annual variation and abnormal temperatures, such as heat waves and cold spells.…”

Background:We developed a habitat suitability index (HSI) model for Pedicularis hallaisanensis, a Grade II Endangered Species in South Korea. To determine the habitat variables, we conducted a literature review on P. hallaisanensis with a specific focus on the associated spatial factors, climate, topography, threats, and soil factors to derive five environmental factors that influence P. hallaisanensis habitats. The specific variables were defined based on the collected data and consultations with experts in the field, with the validity of each variable tested through field studies. Results: Mt. Seorak had a suitable habitat area of 2.48 km 2 for sites with a score of 1 (0.62% of total area) and 0.01 km 2 for sites with a score of 0.9. Mt. Bangtae had a suitable habitat area of 0.03 km 2 for sites with a score of 1 (0.02% of total area) and 0 km 2 for sites with a score of 0.9. Mt. Gaya showed 0.13 km 2 of suitable habitat for sites with a score of 1 (0.17% of total area) and 0 km 2 for sites with a score of 0.9. Lastly, Mt. Halla showed 3.12 km 2 of suitable habitat related to sites with a score of 1 (2.04% of total area) and 4.08 km 2 of sites with a score of 0.9 (2.66% of total area). Mt. Halla accounts for 73.1% of the total core habitat area. Considering the climatic, soil, and forest conditions together with standardized collection sites, our results indicate that Mt. Halla should be viewed as a core habitat of P. hallaisanensis. Conclusions:The findings in this study provide useful data for the identification of core habitat areas and potential alternative habitats to prevent the extinction of the endangered species, P. hallaisanensis. Furthermore, the developed HSI model allows for the prediction of suitable habitats based on the ecological niche of a given species to identify its unique distribution and causal factors.

“…Information on the growth environment of this target plant is crucial in establishing conservation strategies for endangered wildlife and restoring its native habitat (Song et al 2009). In Korea, surveys and studies have been conducted on endangered wildlife and rare plants, such as Pedicularis hallaisanensis Hurus., Polygonatum stenophyllum Maxim., Mankyua chejuense B.Y.Sun et al, and Viola websteri Hemsl., to investigate their habitat location, soil composition, and vegetation structure (Kim et al 2018;Lee et al 2012;Song et al 2009Song et al , 2010. Research on E. hirsutum L. has focused on seasonal variations in reproduction, physiological responses to soil moisture and organic matter (OM) (Lee et al 2018), seed germination characteristics (Cho 2019), cultivation in smart farms (Park 2020), and the development of habitat creation plans (Kim 2022).…”

Background: As wildlife habitats are being destroyed and growth environments are changing, the survival of animals and plants is under threat. Epilobium hirsutum L., a species that inhabits wetlands, has held legally protected status since 2012. However, no specific measures are currently in place to protect its habitat, leading to a decline in remaining populations as a result of land use change and human activities. Results: The growth environment (including location, climate, land use, soil, and vegetation) of the five habitat sites (Samcheok, Taebaek1, Taebaek2, Cheongsong, Ulleung) of E. hirsutum L. was investigated and analyzed. These habitats were predominantly situated in flat areas with gentle south-facing slopes, at an average altitude of 452.7 m (8-726 m) above sea level in Gangwon-do and Gyeongsangbuk-do. The average annual temperature ranged 11.5°C (9.2°C-12.9°C), whereas the average annual precipitation ranged 1,304.5 mm (1,062.7-1,590.7 mm). The surrounding land use status was mainly characterized by mountainous areas, and human interference, such as agricultural land and roads, was commonly found in proximity to these natural habitats. Soil physicochemical analysis revealed that the soil was predominantly sandy loam with a slightly high sand content. The average pH measured 7.64, indicating an alkaline environment, and electrical conductivity (EC) averaged 0.33 dS/m. Organic matter (OM) content averaged 66.44 g/kg, available phosphoric acid (P 2 O 5 ) content averaged 115.73 mg/kg, and cation exchange capacity (CEC) averaged 23.43 cmolc/kg. The exchangeable cations ranged 0.09-0.43 cmol + /kg for potassium (K), 10.23-16.21 cmol + /kg for calcium (Ca), 0.67-4.94 cmol + /kg for magnesium (Mg), and 0.05-0.74 cmol + /kg for sodium (Na). The vegetation type was categorized as E. hirsutum community with high numbers of E. hirsutum L., Persicaria thunbergii (Siebold & Zucc.) H. Gross, Phragmites japonica Steud., Humulus japonicus (Siebold & Zucc.), and Bidens frondosa L.. An ecological flora analysis, including the proportion of lianas, naturalized plants, and annual herbaceous plants, revealed that the native habitat of E. hirsutum L. was ecologically unstable. Conclusions: Analysis of the habitat of E. hirsutum L., a class II endangered wildlife species, provided essential data for local conservation and restoration efforts.
