The production processes of eucalyptus private forests : case study: nertitei and Zalingei localities-central Darfur state-Sudan

Abstract EN

This study was conducted at Nertitei and Zalingei localities during 2015-2017.The aim of this study was to determine the production processes of Eucalyptus private forest in the study area by means of determine the production types, determine the production rotation and to measure the average annual productivity.

Research population consisted of 101 Eucalyptus private forests classified into three categories according to area as followed: The first category (small size sample) 0 – 1 feddan .The second category (medium size sample) 1- 4 feddan.The third category (large size sample) 4- 10 feddan.The research population represented by a sample consisted of 6 forests.

Each category area represented by a sample consisted of 2 even age forest.

Descriptive statistical approach was used for data analysis where Excel statistical programme and simple production tables used.

The study found that the dominant Eucalyptus species in the private forest were Eucalyptus citriodora, Eucalyptus ambalata and Eucalyptus camaldulensis.

The commercial production type in the private forests was the building poles, which are Korki (> 7-10cm) diameter and Rossass (11-17 cm) diameter.

The forest managed under technical rotation , trees selected and felled when it reach the desirable size .

The harvest felling system in the private forest in the study area is the selection felling system.

All the forest started to give production after 4 years from the establishment, then the production continued annually.

The average production for private forest of the study area was 607 building poles/feddan.

Category three (Large size sample) enquired the highest average annual productivity among the three area categories.

The study recommendations including: conducting advance trainings to the owners on the technical and administration of their forests, establishment of demonstrative forests well distributed in the study area.

Raise the awareness of the decision makers in the State and localities governments about the environmental and economic high importance of the private forests; introduce the fire wood production in the productive rotation and establishment of private forests owner societies similar to gum Arabic producer societies.
