Returning to the source lakes of the Cuito and Cuanavale Rivers that the full team had explored a few months earlier, a four-man team led by Chris Boyes set out to retrace earlier paths and cover new terrain.
They also headed further east to explore the catchments of the Cuando and Kembo Rivers, though they did not explore the rivers themselves.
Starting among similar marshy lakes, these two rivers also follow a similar path, flowing southeast and eventually combining and then fanning out into wetlands of their own. Shortly before they would reach the Okavango Delta though, the land rises and forces the waters east. There they join the Zambezi and eventually flow into the Indian Ocean—showing the far-reaching significance of protecting the rain catchment of the Angolan highlands.

Expedition leader Steve Boyes conducts annual surveys of birds across the delta, building a data record and assessing the landscape's health.
On hardy fatbikes, the team checked their camera traps, interviewed villagers, and continued to document biodiversity in Eastern Angola.
The team was able to conduct research in this once war-torn region with the help of an international landmine-removal organization.
This 2015 expedition, at nearly six months and 2,414 km (1,500 miles), lasted longer and covered more mileage than any of the others.
In late 2016, the team completed the first biological survey of the Cuando and Kembo river sources in eastern Angola.
