Preliminary Studies of Phenology of Some Selected Tree Species from Ngel-Nyaki Forest Reserve

A checklist of some selected tree species as data bank on plant phenology (i.e. leafing, flowering and fruiting) at Ngel-Nyaki forest reserve was carried out. Sixteen individual trees belonging to eight species of angiosperm were selected for the study through six months duration. Variation in flowering related to leaf flushing revealed three flowering types; Nov-Dec, Dec-Mar and Jan-Mar. A wide range of producton of new leaves were seen in some species and reproductive phase were correlated to see the relation. Available phenological information on the sixteen individual trees showed that Nov-Dec flowering species were most abundant among the three types recognize. Among species are; Anthocleista vogellii, Bridelia speciosa, Trema orientalis and Dombeya ledermannii. Period of production of new leaves, flowering and fruiting were positively correlated in seven species. Correlation of same in Anthonotha noldeae was insignificant (r=-0.0095).
