Inventory and Spatial Distribution of Invasive Aquatic Plants in the Lower Part of the Nyong River at Lokoundje in the Ocean Department (South-Cameroon)

Abstract:

The study, conducted from February to June 2020, presents a specific inventory of aquatic invasive plants and a mapping of their distribution gained from field observations and data collection campaigns on the lower part of the Nyong River. Specifically, it was a question of inventorying plant species and geo-referencing their biotopes. Through the results obtained, 12 taxa of aquatic invasive species are present (10 species upstream, 08 in transition, and 02 downstream). Of the 12 species, 10 have an ornamental mode of introduction and 01 is endemic to the environment. In addition, it also emerges from this study that the spatial distribution of the species of aquatic plants designated in the study area presents clusters mainly around the islets represented and on certain parts of the banks of the river.
