Description of plantation resources

Introduction

There are three types of wood produced from natural forests and plantations: fuelwood, "bois de service" and "bois d'oeuvre". "Bois de service" includes both poles and roundwood, so it is not possible to determine if they are industrial or non-industrial plantations. "Bois d'oeuvre" includes sawn timbers and can thus be said to be industrial plantations (FAO, 1993).

Development of forest plantations

In 1913, several species were introduced for industrial purposes, including Gmelina arborea, Terminalia superba, T. ivorensis, Tectona grandis, Acacia auriculiformis, Eucalyptus spp., Khaya grandifolia, Cedrela odorata and Pinus spp.

By 1945, other species had been introduced, especially Eucalyptus spp. Between 1945 and 1958, Pinus spp. plantations were established with the aim of supplying materials to industries. Besides, Tectona grandis, Cassia siamea, Gmelina arborea and Anacardium excelsum plantations were established to supply fuelwood, poles and roundwood. Indigenous broadleaved species such as Khaya spp., Terminalia superba, Chlorophora excelsa, Afzelia spp. and Triplochiton scleroxylon were also planted.

After an interruption due to the independence of the country, the establishment of plantations was restarted during 1960-1963 within the framework of a three-year plan. Tectona grandis, Gmelina arborea and Pinus spp. were planted. However, plantations using Tectona grandis and indigenous broadleaved species apparently were stopped after 1963.

Between 1965 and 1971, establishment of plantations using Gmelina spp. was encouraged to produce material for the match industry.

Other species such as P. pinaster, P. merkusii, P. caribaea, etc. were introduced but did not prove successful (Deodatus, 1999).

The total plantation area reached 10 648 ha in 1986 (DNFC, 1993).

Species composition

Many species have been planted for both industrial and non-industrial purposes. Several exotic species have been preferred, particularly Pinus kesiya, P. patula, Gmelina arborea, Terminalia spp., Cassia siamea, rubber and some other broadleaved species (Deodatus, 1999).

Gmelina arborea is used to produce fuelwood, material for matches, poles and roundwood. Pinus spp. are only used to supply industrial material. Other species, such as Tectona grandis and Terminalia spp., are used for fuelwood, poles and roundwood (Deodatus, 1999).

Trend

No information available.

Issues

There are several issues such as lack of silvicultural management and maintenance. Moreover, the number of species that are utilised are limited (Gmelina arborea, Tectona grandis, Pinus spp., Styrax benzoin, Cassia spp., Anacardium spp., Cedrela spp. and Khaya ivorensis) (DFNC, 1993).
