National parks in Korea are subject to a survey of natural resources every five years, according to the Natural Parks Act. This study analyzed the insect diversity in each of the 21 national parks conducted as part of the Third Nature Resource Survey of National Parks (2010~2018). It compared insect diversity in each national park national biodiversity with insect diversity in all national parks and analyzed the uncollected sub-taxonomic groups of each taxonomic group and the legally protected species. The Third Nature Resource Survey identified 5,584 species in 456 families in 21 orders in all national parks, and they accounted for 31.3% of 17,848 species in the national insect diversity. By taxonomic group, Lepidoptera was the most frequently found with 2,195 species, followed by beetles (1,495 species), fellings (712 species), and stink bugs (515 species). By national park, Odaesan national park showed the highest insect diversity with 1,963 species, followed by Sobeaksan national park (1,511), Hanryeohaesang national park (1,321), Gayasan national park (1,282), Juwangsan national park (1,265), Dadohaehaesang national park (1,264), Woraksan national park (1,251), and Jirisan national park (1,240). The legally protected species included 3 species of endangered species rank I, 11 species of endangered species rank II, 12 climate change indicator species, 139 endemic species, and 532 species requiring approval for cross-border transfer.

The Tibetan Plateau is home to the only alpine crane species, the black-necked crane (Grus nigricollis). Conservation efforts are severely hampered by a lack of knowledge on the spatial distribution and breeding habitats of this species. The ecological niche modeling framework used to predict the spatial distribution of this species, based on the maximum entropy and occurrence record data, allowed us to generate a species-specific spatial distribution map in Ladakh, Trans-Himalaya, India. The model was created by assimilating species occurrence data from 486 geographical sites with 24 topographic and bioclimatic variables. Fourteen variables helped forecast the distribution of black-necked cranes by 96.2%. The area under the curve score for the model training data was high (0.98), indicating the accuracy and predictive performance of the model. Of the total study area, the areas with high and moderate habitat suitability for black-necked cranes were anticipated to be 8,156 km² and 6,759 km², respectively. The area with high habitat suitability within the protected areas was 5,335 km². The spatial distribution predicted using our model showed that the majority of speculated conservation areas bordered the existing protected areas of the Changthang Wildlife Sanctuary. Hence, we believe, that by increasing the current study area, we can account for these gaps in conservation areas, more effectively.

The distribution of seabirds was investigated in 24-34 major coastal wetlands in Korea from 2015 to 2019. During the study period, seven orders, 16 families, and 111 species were observed, and the largest number of species (51-89 species) was recorded in 2018. 92,821-265,783 individuals per year were observed with the largest number in 2018. The largest number of species (55-72 species) was observed in the southern sites of Jeollado, and the largest number of individuals (annual average of 62,542 individuals) was found in Chungcheong regions. The largest number of seabird species (68 species) was observed at the Suncheon Bay site in 2016, and the largest number of individuals (95,399 individuals) was observed at Biin and Jangan sites in 2018. In terms of the habitat type of seabirds, at the family level, shorebirds appeared most frequently with an average of 38%, followed by waterfowl, wading birds, seabirds, and raptors. With regard to legally protected species, eight protected marine species, 19 endangered wildlife species (Level I: six species, Level II: 13 species), and twelve natural monument species were observed. Overall, there was a significant difference in the number of species and individuals of seabirds in the Korean coastal wetlands during the research period. This suggests the importance of conducting systematic and continuous seabird surveys and developing a conservation policy considering habitat characteristics.

This study was conducted to clarify the daily activity patterns overlap between hikers and mammals from 2015 to 2019 in the Baekdudaegan protected area. To investigate relationship behaviors between hikers and mammals, we set the camera traps on the ridge of the Baekdudaegan protected area. Daily activity patterns of yellow-throated marten (Martes flavigula) and Siberian chipmunk (Eutamias sibiricus) were highly overlapped with hiker total study periods. Moreover, daily activity patterns of Siberian roe deer (Caperohus pygargus) and water deer (Hydropotes inermis) were highly overlapped with hikers only in spring. In winter, daily activity patterns of wild boar (Sus scrofa) were overlapped with hikers. However, leopard cat (Prionailurus bengalensis), raccoon dog (Nyctereutes procyonoides), and Eurasian badger (Meles leucurus) did not significantly overlap with hikers during the study periods. The daily activity patterns of 8 mammals differed by species-specific behavior and temporal characteristics. Overlap of daily activity patterns between mammals and hikers were differed in each season. Differences in daily activity pattern overlap between mammals and humans may lead to differences in human impact on mammal populations. Information on the interaction between hikers and mammals on species-specific and temporal-specific behavior could be basic ecological data for management and conservation of mammal populations and their habitats.

Ground beetle fauna of Wangpi-cheon watershed in Yeongyang-gun to Uljin-gun, Gyeongsangbuk-do was investigated from May to October in 2012. Ground beetles were collected by pitfall trapping. A total of 38 species of 20 genera belonging to 8 subfamilies were identified from 2,486 collected ground beetles. Species richness was high in Pterostichinae (16 species), Carabinae (8 species), Harpalinae (5 species), Callistinae (3 species), Nebriinae (3 species) and others (1 species). Dominant species were Synuchus cycloderus (1,025 individuals) and Aulonocarabus seishinensis seishinensis (332 individuals), Pristosia vigil (133 individuals), and Coptolabrus smaragdinus branickii (117 individuals) in order. Monthly changes in abundance of upper dominante genera Pterostichus, Aulonocarabus, Coptolabrus species and Synuchus, Pristosia, Colpodes species showed that the former had the highest number in August whereas the latter increased in June and September. The genus Pterostichus species were preferred in deciduous forest in Wangpi-cheon watershed, while the genus Synuchus species were collected in mixes forest adjacent to farmland and recreation facilities and the genera Chlaenius, Harpalus species were collected in mixes forest adjacent to farmland nearby stream. Non-metric multidimensional scaling (NMDS), ground beetles and sites could be divided into two distinct groups: St. 1, St. 2, St. 3 group and St. 4 group. Some species such as Pterostichus orientalis orientalis, P. vicinus and P. bellatrix were particularly abundant at St. 4.

Through the analyses of the distribution characteristics and management practices of the wildlife protection areas, this study intends to present basic data for improving the management of protected areas. 1) Based on the aggregate results of the protected areas, the average ratio of the metro-city and provincial areas to the designated protected areas was 1.49%; except for Chungcheongbuk-do (8.83%) and Gyeongsangnam-do (3.43%), most regions showed specified percentages of about 1%, whereby the analysis suggested that the designated protected areas were too small. 2) Considering the fact that most (86.16%) of the wildlife protection areas are in the regions that are of ecological nature level of grade 1, green nature level of grade 8 or better, and of legal conservation regions and districts, it was shown that these reserves are distributed in regions with excellent natural environmental conditions. 3) Designation of protected areas for the protection of wildlife and fish is deemed to be necessary. Although there are 588 wildlife & plant reserves, there are absolutely no designated areas for protecting plant and fish species. 4) Based on the results of an analysis of the current distribution by types, 92.47% of protected areas were concentrated in the mountains, 0.24% in the agricultural lands, and 7.29% distributed in the lakes/rivers/costal areas. 5) As major improvement projects, proposed were: advancement of management systems for protected areas, expanded designation of protected areas, overhaul of managed areas, designation of protected areas for the protection of wild plants and fish, need for management measures for private property and the surrounding areas, need to secure appropriate management personnel and collaboration, locally-adapted management, eco-information-based management, total management of protected areas, etc.

Coniferous forests in the Baekdudaegan protected area are gradually losing their landscape diversity and uniqueness along with their ecological stability due to changes in vegetation composition and structures caused by various disturbance factors, such as climate change, vegetation succession, and human interference. This study provides basic data for establishing a comprehensive conservation plan for coniferous forests in the Baekdudaegan protected area. We classified the vegetation unit types using the Zurich-Montpellier School of Phytosociology and two-way indicator species analysis methods and analyzed the species diversity and structural characteristics based on the vegetation information of 755 stands collected in the natural resources change survey of the Baekdudaegan mountains (2016 to 2020) by the Korea Forest Service. Therefore, the vegetation of the coniferous forests of theBaekdudaegan protected area was classified into 15 types under the vegetation unit hierarchy of two community groups, four communities, seven sub-communities, and 14 variants. Furthermore, we compared the total coverage among vegetation types, importance values, constancy classes, life-forms, and diversity indices. Additionally, the average total coverage and number of species per 100 m² of all coniferous forests were 232% and 21 species, respectively, with the species diversity and dominance indices averaging 1.907 and 0.222, respectively.

The aim of this study was to provide the basic information necessary to identify Korean fir (Abies holophylla), momi fir (A. firma), and Nikko fir (A. homolepis), and other fir trees planted in South Korea that are protected by law. Analysis of the morphological characteristics of the needles from each sample was investigated. The shape of the needle-leaf tip from A. holophylla was acute, whereas that from A. firma and A. homolepis was emarginate and that from the protected fir trees was obtuse. The number of stomata on the needles was not significantly different between A. holophylla and A. firma, and the number of stomata on the needles from A. homolepis and the protected fir trees were highly similar. In addition, the genetic differences among the Abies species were analyzed using the sequences of five chloroplast DNA regions-matK, atpF-atpH, rpoC2-rps2, rpoC1, and psbA-trnH.The atpF-atpH and psbA-trnH regions were useful for discriminating A. firma from the other species, but there were no differences among A. holophylla, A. homolepis, and the protected fir trees. The same chloroplast sequences were found in both A. holophylla and A. homolepis, which suggests that additional genetic studies might be necessary to identify the Abies species planted in both South Korea and Japan.
