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 Loky- Manambato 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, l'activité relative (Trap Success) et la distribution spatiale (Naïve occupancy) à travers le paysage. Pour ce faire, nous avons utilisé 60 caméras activées par le mouvement pour surveiller le long des sentiers établis dans trois parcelles forestières à travers l’AP Loky-Manambato : Antsahabe, Bekaraoka et Antsaharaingy. Nous avons étudié chaque forêt pendant deux semaines en septembre et octobre 2018. Nous avons procédé à 498 captures indépendantes de la faune à travers le paysage, incluant cinq des six carnivores endémiques connus pour habiter l'Est de Madagascar : Galidia elegans, Galidictis fasciata, Eupleres goudotii, Fossa fossana et Cryptoprocta ferox. Nous avons constaté que F. fossana et G. elegans étaient les carnivores les plus actifs et les plus largement distribués, tandis que C. ferox, G. fasciata et E. goudotii étaient les moins nombreux. De plus, nous avons documenté la présence de deux carnivores envahissants : Canis familiaris et Felis catus. Ces découvertes ont étendu l'aire de répartition la plus septentrionale connue de Galidictis fasciata (Antsahabe) et de Fossa fossana (Bekaraoka) dans l’AP Loky-Manambato. La taille de la forêt n'était pas un bon prédicteur de l'activité ou de l'occurrence car la plus grande parcelle forestière de Bekaraoka avait la moindre présence de tous les carnivores. Nos résultats mettent en évidence une partie de la biodiversité au sein de Loky-Manambato PA et la nécessité d'une gestion efficace dans cet écosystème forestier de transition unique
