Preliminary survey of the threatened carnivores in the Daraina Loky-Manambato Protected Area, Madagascar

Madagascar’s protected areas safeguard numerous threatened endemic plant and animal species, including Euplerid carnivores, considered to be the most threatened yet understudied group of carnivores globally. The Loky-Manambato Protected Area (PA) in northern Madagascar encompasses a unique transitional forest ecosystem that is under pressure from forest loss and fragmentation. We provide the first photographic survey of Madagascar’s carnivore community occupying this region with the aim of documenting carnivore species richness, relative activity (Trap Success), and spatial distribution (Naïve occupancy) across the landscape. To do this, we used 60 motion-activated cameras to survey along established trails in three forest patches across the Loky-Manambato PA: Antsahabe, Bekaraoka, and Antsaharaingy. We surveyed each forest for two weeks in September and October 2018. We collected 498 independent captures of fauna across the landscape, including five of the six endemic carnivores known to occupy eastern Madagascar: Galidia elegans, Galidictis fasciata, Eupleres goudotii, Fossa fossana, and Cryptoprocta ferox. We found F. fossana and G. elegans to be the most active and widely distributed carnivores, while C. ferox, G. fasciata and E. goudotii were the least. Additionally, we documented the presence of two invasive carnivores: Canis familiaris and Felis catus. These findings extended the northern-most known range of Galidictis fasciata (Antsahabe) and Fossa fossana (Bekaraoka) into the Loky-Manambato PA. Forest size was not a good predictor of activity or occurrence as the largest forest patch in Bekaraoka had the fewest captures of all carnivores. Our findings highlight some of the biodiversity within the Loky-Manambato PA and the need for effective management across this unique transitional forest ecosystem. Les aires protégées de Madagascar protègent de nombreuses espèces végétales et animales endémiques menacées, y compris les carnivores eupléridés. Les carnivores eupléridés sont considérés comme l'un des groupes de carnivores les plus menacés mais les moins étudiés au monde. L'aire protégée (PA) de LokyManambato dans le nord de Madagascar englobe un écosystème forestier de transition unique qui subit la pression de la perte et de la fragmentation des forêts. Nous fournissons la première étude photographique de la communauté de carnivores de Madagascar occupant cette région dans le but de documenter la richesse en espèces de carnivores,
