Introduction of fuelwood tree species on degraded lands in Paseh and Kadipaten areas.

Abstract

The results are reported of trials of 16 species established in 1983 at Paseh and in 1985 at Kadipaten, Indonesia. The species were: lamtoro, Leucaena leucocephala; kaliandra, Calliandra calothyrsus; kayu afrika, Maesopsis eminii; gamal, Gliricidia maculata [G. sepium]; Hymenea [Hymenaea] courbaril; angsana, Pterocarpus indicus; Enterolobium cyclocarpum; khaya, Khaya anthotheca; turi, Sesbania grandiflora; akor, Acacia auriculiformis; hue, Eucalyptus alba; mangium, Acacia mangium; johar, Cassia siamea; Cassia fistula; kayu kupu-kupu, Bauhinia purpurea; and Pericopsis mooniana. Five of the species (L. leucocephala, Calliandra calothyrsus, A. auriculiformis, S. grandiflora and G. sepium) were also examined for coppice shoot production after cutting 20, 40 and 60 cm above the root collar. These same 5 species also grew best and had fuelwood of a high calorific value; they are, therefore, recommended for large-scale planting. L. leucocephala, G. sepium and Calliandra calothyrsus showed a high coppicing ability, and stump height did not affect the coppice biomass production. Coppicing is, therefore, recommended for management of these 3 species. [With English tables and figures.]
