Measurements were carried out of the gas exchange properties (namely, photosynthesis, stomatal conductance and transpiration rates), water use eﬃciency and water relations of two mangrove species, Rhizophora mucronata and Ceriops tagal at Gazi Bay, Kenya. Rhizophora mucronata had signiﬁcantly higher photosynthetic rates than C. tagal. Internal CO2 concentrations were higher during the wet season than the dry season in both species.Gas exchange properties were correlated positively with photon ﬂux density in both species. Leaf water potentials were highest during the morning and lowest at midday and were also highest in the lower canopy leaves in both species. The two mangrove species had conservative water use. Management potential for the East African mangroves based on the results of this study is suggested.
