This account summarises studies based on tree data from plots established during the 1930s and 1940s in Budongo, a Ugandan rain forest. The original interpretations of forest change provoked controversies that continue to the present day. Analyses have yielded three categories of results: the fir...

Tree stems contract and expand as stem water is depleted and replaced. Band dendrometer studies suggest that such daily changes are small (<0.2 mm diameter), and they are ignored in most growth measurements. However, several studies using other approaches note larger changes (even >1 cm diameter)...

Sixteen percent of tree stems 10 cm diameter or greater recorded in seven 1 ha plots in Rabongo Forest, Uganda had stem damage attributable to elephants (Loxodonta africana). We propose four strategies that may help tree species persist under these conditions: repellence, resistance, tolerance an...
