Five Year Results of Species and Provenance Trials with Cold-resistant Eucalypts in Lesotho

Abstract

Following the rejection of all but one eucalypt species from Lesotho's woodlot planting programme, 118 provenances of 46 species of eucalypts were imported from Australia in 1978 and 1979. Twenty six sources of 14 species were selected for potentially high cold-hardiness and were planted in replicated experiments at lowland and mountain sites. After five years, provenances of new species could be identified for woodfuel production at both altitudes and a new provenance of Lesotho's main hardwood. Eucalyptus rubida, could be recommended for use in both zones. Additionally, Eucalyptus stellulata proved most suitable especially in colder, wetter areas and is now being planted. Similarly, Eucalyptus macarthurii and Eucalyptus nitens are now planted at lower altitude, whilst further provenance research is recommended for three species: Eucalyptus glaucescens, Eucalyptus nova-anglica and Eucalyptus gunnii.
