Following the phenological observations of the species of the Forest Reserve of Kalikuku in the face of seasonal variations in the climate, data on 30 taxa divided into 25 botanical families were collected. Fabaceae have more species than other families (16.6%).Defoliation (from May to August) is noticeable in 50% in Parinari holisti and Trema orientalis, in 70% in Carapa grandifolia and Ocotea usambarensis and in 100% in Bridelia micranthalj, Albizia gummifera and Piptadeniastrum africanum.Whereas, for the entire massif, flowering (November-mid-February) and its peak (December-January), fruiting (January-April), sheath dissemination (March-June), then regeneration (August-December) synchronously with the foliage influenced, at the same time, by precipitation from August to December, are the events summarized in the phenogram. As for the local use of wood, the surveys revealed 8 species involved in crafts, 12 in herbal medicine and 10 in mushroom production.

Abstract: (french)
A la suite des observations phénologiques des essences de la Réserve Forestière de Kalikuku face aux variations saisonnières du climat, des données sur 30 taxons reparties en 25 familles botaniques ont été rassemblées. Les Fabaceae présentent plus d’espèces que d’autres familles (soit 16,6%).La défoliation (de Mai en Août) se remarque en 50% chez le Parinari holisti et le Trema orientalis, en 70% chez le Carapa grandifolia et l’Ocotea usambarensis et en 100% chez le Bridelia micranthalj, Albizia gummifera et le Piptadeniastrum africanum.Alors que, pour l’ensemble du massif, la floraison (Novembre-mi-février) et son pic (Décembre-Janvier), la fructification (Janvier-Avril), la dissémination des gaines (Mars-Juin), puis la régénération (Août-Décembre) en synchrone avec la frondaison influencées, en même temps, par les précipitations d’Août à Décembre, sont les événements.résumés dans le phénogramme. Quant à l’usage local du bois, les enquêtes relèvent 8 espèces intervenant en artisanat, 12 en phytothérapie et 10 en production des champignons.
