The Felda Aring - Tasik Kenyir Road was identified as one of the most threatening roads to wildlife in Malaysia. The present study was conducted to assess the road crossing activities involving the medium- to large-mammal species due to the problem stated. The objectives of this study were to (1) predict the suitability of the road and its surroundings as the roaming areas for the Asian elephant (Elephas maximus, n = 104) and Malayan tapir (Tapirus indicus, n = 66), (2) identify the mammalian species inhabiting the forest beside the road, (3) compare the forest’s common species [photographic capture rate index (PCRI) > 10/ detection probability (P) ≥ 0.05] with the ones utilising the road crossing structures; the viaducts and the bridges, and (4) determine the most impacted species from traffic collisions. The road and its surroundings were classified as moderately suitable to the elephant and tapir (suitability values = 0.4 - 0.8). A total of 16 mammal species were recorded at the forest edges, in which the wild pig (Sus scrofa) (PCRI = 118.96, P = 0.3719 ± 0.027), barking deer (Muntiacus muntjak) (PCRI = 68.89, P = 0.2219 ± 0.0232), sun bear (Helarctos malayanus) (PCRI = 11.13, P = 0.0507 ± 0.0159), tapir (PCRI = 11.13, P = 0.0469 ± 0.0118), elephant (PCRI = 10.7, P = 0.0787 ± 0.0195) and Malayan porcupine (Hystrix brachyura) (PCRI = 10.7, P = 0.103 ± 0.0252) were the common species utilising the crossing structures. In contrast, the Asian palm civet (Paradoxurus hermaphroditus) and leopard cat (Prionailurus bengalensis) were the most frequently hit species on the road [F(7,398) = 28.53, p < 0.0005]. The present study found that large-mammal species were utilising the crossing structures at a higher frequency, whereas more medium-mammal species were involved in traffic collisions.
