To estimate the food actually available to folivores, it is necessary to study the leafing phenology and distribution of the many species of rain forest plants. The evergreen forest of Ipassa (Figure 1) which is 10 km south of Makokou, Gabon, at an elevation of 500 m, was studied in 1971-1972 and in 1975 from a floristic and ecological point of view. Phenological data on tree and liana species were completed by a quantitative study of litter-fall. Leaves of all the species in the litter collected were identified, so as to obtain a quantitative and phenological analysis of the leafing characteristics of the different species. The climate at the Ipassa field station is characterized by a major dry season during which the sun rarely shines and the average temperature is at a minimum of about 21° C. Consequently, there is a minimum of evaporation in this dry season. The average yearly rainfall is 1700 mm. The four equatorial seasons are shown in Figure 2 with more detailed data concern- ing our main period of study:. Figure 2. Data from the meteorological station of Makokou con- cerning the main period of phenological observations. Tem- peratures are monthly means (broken lines show maxima and minima). Insolation is the total time of bright sunshine per month. The records of daily rainfall show the different patterns of distri- bution during the rainy season and total absense of precipitation during the major dry season (also characterized by minimum inso- lation and minimum temperature)..
