RESUMECe document présente les données recueillies sur Lepidochelys olivacea le long des côtes de la réserve de Campo-Ma'an au Cameroun. Les études menées de 1998 à 2005 ont consisté en un recensement des espèces venant pondre sur les plages et une délimitation des périodes de pontes. Des mesures ont été également effectuées sur les spécimens rencontrés et à partir des carapaces collectées. Les résultats montrent que, Lepidochelys olivacea pond sur les côtes de l'UTO Campo Ma'an entre octobre et mars, avec un taux élevé de ponte entre novembre et janvier. La longueur moyenne (68,98 cm) et la largeur moyenne (68,66 cm) de la courbe de la dossière ont été observées sur les sites pour 118 Lepidochelys olivacea marquées sur les plages du Cameroun. L'identification des carapaces a montré la présence des juvéniles (19)(20), subadultes (40-45) et les adultes de Lepidochelys olivacea au Cameroun.

In Cameroon, marine turtles are usually captured accidentally in fishing nets. Among the species captured, the green turtles are captured through out the year but they lay eggs on the coast irregularly. To carry out study on Chelonia mydas, data on the identification of 77 Sea Turtles was collected from 1998 to 2005 using sea turtle carapace on sale along the road and in all households of the 10 villages between 75 Km from of Kribi and Campo. The capture and recapture method was used with the participation of fishermen and the regional marine turtles protection team. To identify and measure live or dead turtles and to tag with MONEL flipper tags, all live and untagged turtles caught in the nets of local fishermen, we were present when fishermen returned from fishing trips. Turtles captured having tag numbers were registered by their tag numbers. The team also carried out monitoring of nests along the 15 km beach between Mbendji and Bekolobe for four years (1998 to 2002). 134 turtles were tagged and released in the wild. A total of 209 green turtles (Chelonia mydas) were identified and measured along the coastal zone of the Campo Ma'an national park. The average curved carapace length was 50, 29 cm and the width was 49, 99 cm. In the small classes of curved carapace length (30-40) cm, the animals increase till a maximum of class length (45-50) cm and the number decreases progressively and stops when the values of the class length are 70-75 cm. Among the tagged animals, 18 were recaptured approximately 3 km from the release site, thus indicating relative sedentary juvenile green turtles around the Campo Ma'an coastline. Only one sea turtle migrated into the Equatorial Guinea coastline after two years.

Abstract.-This work was carried out to study the flowering phenology in a young forest of about fifteen years old. For its location in the intrication zone of mixed forests, this forest was made up of both evergreen and deciduous species. Six strata and distinct sub-strata, with already defined biophysiognomic types and according to the stratification-type model, were observed to study flowering phenology through its rhythm, diversity and intensity. Generally, the floral diversity and intensity showed a parallel evolution, except during the long dry season and part of the short rainy season, in the course of which mass flowering were observed. At the level of some strata, seasonal expression greatly differed with that of the whole forest. The model of a unique annual flowering during the long rainy season or the long dry season, combined with an average anthesis duration, was observed in a good number of species in this forest. Nevertheless, when considering flowering duration, some variations in phenologic behaviour with respect to stratum were noted within certain species.
