Inventorying riparian vegetation species for monitoring the Boro River, Okavango delta.
The Boro River is one of the major channels in the Okavango Delta that experiences a lot of interaction from the society in Maun. In the
beginning of the 1990s, it was targeted for dredging to increase outflow into the Thamalakane River in order to augment the water supply
for Maun village. However, the process of dredging was met with opposition from the local and international communities. This would
have had major impacts on the biodiversity along the river, especially the riparian vegetation. The riparian vegetation provides a lot of
services to wildlife and to the society in Maun. However, there is no inventory and monitoring of this vegetation. The objective of this
study was to inventory plants on the riparian vegetation along the Boro River in order to provide baseline data for the monitoring of biodiversity
change in the area. Sites were selected randomly, then transects were placed across the riparian vegetation and quadrats randomly
selected to inventory woody and herbaceous plants. A 30m x 30m quadrat was used for sampling woody species and a 50cm x 50cm for
herbaceous species. A total of 18 woody species, 9 grasses, and 29 herbs were identified in the study area. The woody species provided
a habitat for understory species, which were mainly herbs. Grasses were less dominant in the understory as compared to herbs or weeds.
This might be because grasses prefer to grow in open areas where there is more sunlight as compared to weeds that prefer to grow under
shades. This study provided a synopsis of the vegetation dynamics within the riparian areas in the Okavango Delta. Further studies are
needed for in-depth knowledge of the dynamics in riparian vegetation along major channels in the Okavango Delta.
