Juniperus procera Hocht. ex. Endl. in Ethiopian forestry

Abstract

The distribution, importance and growth potential of Juniperus procera Hocht. ex Endl., an indigenous conifer in the Ethiopian highlands, were analyzed. As a termite- and fungi-resistant local timber J. procera has been highly valued for the construction of houses and larger buildings such as churches. Decimation of natural forests over the past 100 years, which is continuing, has halted the utilization of J. procera. By analyzing the few remaining J. procera stands of various ages between 10 and 200 years, its growth potential was calculated as maximum mean annual increment (MAI) of 7.5 m 3 ha −1 year −1 at the age of 55 years. The most rapid volume growth occurs at the ages of 15–50 years. The dominant height reaches about 45 m at ages between 100 and 150 years. Favoring J. procera in planting instead of Cupressus lusitanica Mill. is a way to diversify species selection, and to supply durable timber of high local and national preference. The relatively low yield potential of J. procera compared with exotics calls for national or international inputs for plantation establishment.
