Rivers in Cameroon were surveyed to collect and document rheophytic plants. Rheophytes are the dominant aquatic macrophytes in tropical river systems, where they are adapted to extreme environments of rushing water (e.g., river rapids, waterfalls and flash floods). Rheophytic plants are useful indicators of river health. However, their habitats are threatened by human activities such as agriculture, plantation development, alluvial mining and dam construction, particularly in tropical countries. In this survey we documented 66 rheophytic species in 29 genera and 16 families. Two ferns, 8 monocotyledons and 56 dicotyledons were listed. Apart from the Podostemaceae family in which all species are rheophytic, the other 15 families have few species which are rheophytic. Five of these families have up to four species and the remaining 10 have only one member as a rheophytic species. The conservation status of each species is assessed and discussed. This work urges botanists, conservationists, and policy makers to do more to protect the habitats of rheophytes and put in place strategies and action plans for the conservation of this important biological group

The Dja Faunal Reserve located in southeastern Cameroon represents the largest and
best protected rainforest patch in Cameroon. Here we make available a dataset on the
inventory of tree species collected across the Dja. For this study nine 5 km long and 5 m
wide transects were installed. All species with a diameter at breast height greater than 10
cm were recorded, identified and measured. A total of 11546 individuals were recorded,
corresponding to a total of 312 species identified with 60 genera containing unidentified
taxa. Of the 54 identified families Fabaceae, Rubiaceae and Malvaceae were the most
species rich, whereas Fabaceae, Phyllantaceae and Olacaceae were the most abundant.
Finally, Tabernaemontana crassa was the most abundant species across the Reserve. This
dataset provides a unique insight into the tree diversity of the Dja Faunal Reserve and is
now publically available and usable.
