The management of protected areas requires constant adaptation to current context, managers must decide on methods for assessing and monitoring values of their conservation area. This choice must be based on simple methods that are efficient and less costly in terms of time and costs in a scarce financial resources context. Fourteen (14) Bushnell-branded trap cameras were deployed, which were used to collect data throughout the follow-up period which runs from February to April 2018. The sampling points were chosen at random and the choice of the location of the camera in the sampled part is based on certain essential criteria for a good follow-up. Indeed, it would be necessary to take into account the trails used by wildlife and the availability of a hang support for cameras. Data collected during the follow-up period concern three hundred and sixty-seven (367) nights traps or 8808 hours. Two (02) of the fourteen (14) trap cameras deployed for the collection system did not work: one is stolen and the other do not fonction well. Nineteen thousand six hundred and forty-six (19646) pictures of mammalian fauna were captured by the trapping cameras in which twenty-nine (29) species were identified. The diversity index varied from 2.38 bits in February to 3.89 bits in March respectively; it fell in April with 1.65 bits. Pielou's equitability was respectively 0.51, 0.81 and 0.37 for above mentioned months. Animal density estimated from distance sampling points transect showed fluctuating densities (4.87; 3.40 and 5.23 individuals per ha) depending on the month (February, March and April).

Abstract
The management of protected areas requires constant adaptation to current context, managers must decide on methods for assessing and monitoring values of their conservation area. This choice must be based on simple methods that are efficient and less costly in terms of time and costs in a scarce financial resources context. Fourteen (14) Bushnell-branded trap cameras were deployed, which were used to collect data throughout the follow-up period which runs from February to April 2018. The sampling points were chosen at random and the choice of the location of the camera in the sampled part is based on certain essential criteria for a good follow-up. Indeed, it would be necessary to take into account the trails used by wildlife and the availability of a hang support for cameras. Data collected during the follow-up period concern three hundred and sixty-seven (367) nights traps or 8808 hours.

Abstract: (french)
La gestion des aires protégées exige une constante adaptation au contexte du moment, le gestionnaire se doit d’arbitrer le choix des méthodes d’évaluation et de suivi des valeurs de sa zone de conservation. Ce choix doit être porté sur des méthodes simples efficaces et moins couteuses en termes de temps et de coûts du fait de la rareté des ressources financières. Les nouvelles technologies offrent une gamme d’appareils qui sont de plus de plus utilisés dans le cadre de la conservation de la biodiversité. Dans cette recherche, il a été déployé 14 caméras pièges le long de la période de suivi qui s’étala de février à Avril 2018. Les données collectées au cours de cette période ont concerné trois cent soixante-sept (367) nuits pièges soit 8808 heures. Deux (02) caméras pièges sur les quatorze (14) déployées pour le système de collecte n’ont pas fonctionné l’une suite à un vol et la seconde du fait d’un disfonctionnement. Dix-neuf mille six cent quarante-six (19646) images de la faune mammalienne ont été capturées par les caméras pièges dans lesquelles vingt-neuf (29) espèces ont été identifiées. L’indice de diversité a varié respectivement de 2,38 bits en février à 3,89 bits en mars; il a connu une chute en Avril avec 1,65 bits, l’équitabilité de Pielou a été respectivement de 0.51, 0.81 et 0.37 pour les mois cités. La densité animale estimé à partir des points transect de distance sampling a montré des densités fluctuantes (4,87; 3,40 et 5,23 individus par ha) en fonction des mois (Février, Mars et Avril).
