Abstract. This study on the monitoring of the diversity and abundance of wildlife around the wildlife corridor area on Highway 304, which passes through Khao Yai and Thap Lan National Parks, was conducted during September 2017 and May 2021 using camera traps to constantly monitor the area. A total of at least 51 wildlife species from 30 families, 14 orders were recorded. The species with the highest abundances were Sambar Deer, Wild Boar, Northern Pig-tailed Macaque, Gaur, Northern Red Muntjac, Siamese Fireback, Malayan Porcupine, Red Junglefowl, etc. The wildlife species recorded include 2 critically endangered species, 3 endangered, 10 vulnerable, 1 near threatened. In this study we also recorded images of a Fishing Cat, which is the first photographically record in this World Heritage Site. The evenness index indicates that the wildlife community in the area is stable. No significant differences in the diversity and abundance of wildlife before or after the corridor construction were seen. The wildlife in the area were active throughout the day. We also found that the highway is the main factor effecting the presence of wildlife. The study results show the importance of this area that the highway passes through. Building wildlife corridors between the two national parks is very important for maintaining the wildlife community as well as continuity. Suggestions from the study include management of human activity in the area including traffic, noise, vehicle speed and living activities in the area that may attract wildlife closer to the community and cause other impacts.

Abstract. Chanachai Y, Nathalang A, Duengkae P, Sukmasuang R. 2022. Species diversity, abundance, and movement of small mammals in the dry evergreen forest at Khao Yai National Park, Thailand. Biodiversitas 23: 5892-5901. Small mammals play an integral role in the forest ecosystem. This research was conducted on The Mo Singto Forest Dynamics Plot, Khao Yai National Park. Trapping of small mammals was carried out in June-September 2019 and from January-April 2020 based on a total of 64 Tomahawk for small mammal live traps were systematically placed in an 8×8 grid of 20 m intervals, ripe bananas and palm oil as bait was used. Trap cages were opened for 3 consecutive months per season in each study period covering a total study period of 1 year. The result showed that a total of 4015 individuals from 9 species, 9 genera, 4 families and 3 orders were captured with a sampling effort of 32,555 trap nights. The most common species were Red Spiny Rat (Maxomys surifer), followed by Northern Tree Shrew (Tupaia belangeri), Long-tailed Giant Rat (Leopoldamys sabanus), Indochinese Ground Squirrel (Menetes berdmorei), Asian House Rat (Rattus tanezumi), Indomalayan Niviventer (Niviventer fulvescens), Savile's Bandicoot Rat (Bandicota savilei), (Tamiops mcclellandii), and Short-tailed Gymnure (Hylomys suillus) respectively. Considering the number of small mammals caught, Maxomys surifer was the most abundant, accounting for 61.69% of all mammals caught. The sex ratio was found to somewhat favor females in both seasons. This study indicated that the small mammal diversity was high in the primary dry evergreen forest. These results have important implications not only for conservation but are also useful for further investigation if there is any disturbance or change in the area or any potential disasters that may occur in the future.

Abstract. Nanla Y, Marod D, Duengkae P, Paansri P, Noowong J, Manitoem C, Sukmasuang R. 2024. Factors influencing appearance and suitable habitat for wild elephants in the Khao Yai National Park, Thailand. Biodiversitas 25: 3061-3072. Protected areas are designated to conserve biodiversity and provide a safe habitat for wildlife. This study aims to investigate the factors affecting elephant appearance and changes in habitat. The maxEnt program was used to analyze data derived from the patrolling system with constant quality monitoring. Four categories of environmental factors, climatic, physiological, biological, and anthropological factors were used to analyze the wild elephant data yearly from 2017 to 2022. The aim was to understand the effect of environmental factors on the wild elephants’ appearance and their habitat suitability. The results showed an average area under the receiver-operating-characteristic curve (AUC) was 0.81±0.004 SD. The results indicated that climatic (42.97%), physiological (32.62%), and anthropological (21.23%) factors affected the appearance of wild elephants significantly. Temperature factors showed the highest percentage contribution (39.04%), while water sources and salt licks, considered physiological factors, contributed 22.13% and 5.06%, respectively. Habitat suitability analysis revealed that the majority of the park area (64.91%) was categorized as unsuited and poorly suited habitat areas, while 35.07% was categorized as moderated and well-suited habitat areas for wild elephants. Implementing strategies to improve water sources and salt lick sites within the park and managing the area to minimize human disturbance both on the surrounding boundaries and the tourist destination sites are recommended to manage the wild elephant.
