Abstract

Eucalyptus spp. have been widely planted for timber in the tropics and subtropics and have been promoted by both Governments and businesses. In Sri Lanka, in the semi-dry zone, north of Kandy there are extensive stands of 30-40 year old E. camaldulensis, some of which were planted by a company for commercial fuel wood. Poor growth, and a change in fuel technology, has made these plantings redundant. The company is returning its leased holdings slowly back to near-natural forest. In order to do this, it undertook trials to determine the best way to control coppice re-growth from cleared Eucalyptus. Finding a cost-effective way of controlling Eucalyptus re-growth will assist Government and other landholders in reviving natural forest and promoting the associated ecosystem services such as water retention, provision of herbs, and honey. The use of chemicals, light exclusion and a variety of physical control techniques was tested at two locations near Naula, Matale District. The most effective method was cutting the stems down to the ground and then covering with well-secured heavy gauge plastic. The next best method, but more expensive, and with no problems of waste disposal or recycling associated with polythene, was the cutting of any coppice growth as soon as it emerged. After 4 rounds of coppice control all stools died. Chemical controls proved ineffective and expensive. Uncontrolled coppice, almost all regrew. If possible, control without the use of chemicals is preferable.
