“…They can be seen catching small animals that stand on the road so it's possible that when a snake or other reptile dies by car collision, these birds of prey take them away, probably causing a lack of data for this group. Scavenging and carcass removal as been reported by other authors as Zhang and collaborators (2018) or Kummoo et al (2020). The only snake present in the study was possibly registered due the particularity of the location.…”

Road-killed animal surveys are scarce in Spain compared to other countries. Also, the majority of the published papers about this issue, comprehends data analysis from particular species or involve only motorways or highways. This paper presents the monitoring of a common road during three years, from 1st January 2020 to 31st December 2022 (both included), in order to evaluate wildlife loss by car hits. At the end of the survey, 53 individuals from 19 different species were found. The most affected groups were mammals with the 75% of car collisions and birds which obtained the 23% of total roadkills. Only one reptile was registered during the sampling. End of spring and summer were the seasons where wildlife was affected in high way, while autumn was the one with less fauna affection. The landscape across the road seems to influence on the biodiversity loss and according to conservation interests, most of the registered animals belongs to endangered or protected species, especially birds and reptiles. Also domestic animals like cats and dogs were directly affected by vehicle collisions. Annual results showed that roadkill data increased along the three years of survey, being 2020 the year with less incidences, probably due to the mobility restrictions established during the COVID-19 crisis.

“…304 that pass through KYNP and Thap Lan National Park on the wildlife between December 2018 and August 2019 with a total accumulative distance of 1062 km found 41 wildlife carcass species, with 176 individuals were killed that showed 0.17 WVCs km -1 . Kummoo et al (2020) reported the WVCs on the highway that cuts through Nam Nao National Park, Thailand. Based on a 1496 km survey, they reported 1389 carcasses of 578 amphibians, 540 reptiles, 190 mammals, and 81 birds, which accounted for 1389 carcasses or 0.93 WVCs km -1 .…”

Abstract. Rattanawanawong N, Bhumpakphan N, Kutintara U, Sukmasuang R. 2022. Wildlife-vehicle collisions in Khao Yai National Park, Thailand: Impact on native species for some conservation management. Biodiversitas 23: 3050-3061. Wildlife-vehicle collisions (WVCs) remain a major challenge in wildlife management worldwide, especially in conservation areas with transport routes passing through. This study was operated along a 48 km long highway, which conducted 207 surveys in a natural world heritage site from February 2018 to January 2019. A total of 391 wild animal carcasses were found in 90 species. The carcasses found, according to the taxonomic group, were reptiles (67.52%), followed by mammals (14.83%), amphibians (4.35%), birds (3.32%). Reptiles were most affected by road use, especially tortoises in Family Geoemydidae and Family Testudinidae that two critically endangered species were found. This study found that members of Family Colubridae were most affected that 26 species, a total of 144 animal carcasses were found, accounting for 29.15% of the number of all carcasses. The most affected species were forest garden lizard (Calotes emma) in the Family Agamidae, where 99 carcasses were found, accounting for 25.31% of the total. In March showed the highest number of the carcasses, followed by April. All of the carcasses found in the evening slightly more than the morning indicated that wild animals died more during the day than at night. The number of vehicles day-1 significantly affected wildlife mortality per day. Reducing the number of vehicles per day-1 entering and reducing vehicle speed, including the number of tourists, as well as banning travel at night, would mitigate the problem. Further, educational signage about wildlife diversity and the risk of road mortality should be installed at the park to remind visitors about the unique fauna in the national park and emphasize the importance of conservation.

“…Roadkilled O. porphyraceus have been reported from Hong Kong, Thailand, and Taiwan (Karsen et al 1998;Kummoo 2020;Lin 2022). Roads dissecting natural habitats force animals to cross these hazardous artificial linear structures to search for mates and to locate critical resources (Smith 2003).…”
