Description :
Deposits beneath Mubwindi Swamp provide a partial record of vegetation history since at least 43,000 yr ago. The AA. studied pollen from 2 cores and obtained 9 radiocarbon ages from 1 of these cores and 3 radiocarbon ages from the other. Pollen deposited before and soon after the last glacial maximum represents vegetation very different from the modern vegetation of the Mubwindi Swamp catchment. The pollen data provide evidence for a late glacial montane forest refuge near Mubwindi Swamp. During the past 2500 yr, a combination of climatic and human-induced changes in vegetation can be seen in the pollen records.
