The tree is widely exploited for its very valuable timber, which is traded internationally, and plantations have been established in several countries. A high. Identity. Top of page.

Khaya ivorensis is distributed from Côte d’Ivoire east to Cameroon and south to Cabinda (Angola); it possibly also occurs in Guinea, Liberia.

Logs may have a spongy or brittle heart, and care is needed in felling and sawing operations. From Wikipedia, the free encyclopedia. More extensive establishment of plantations of Khaya ivorensis is certainly desirable in tropical Africa, but Hypsipyla attack is a serious drawback.
Khaya ivorensis occurs scattered or in small groups in the forest, usually in low densities. Plant Resources of Tropical Africa Introduction.
It is fairly widely grown in plantations within its natural area of distribution, but also in tropical Asia and tropical America.
Khaya ivorensis (PROTA) – PlantUse English
It can be found in lowland rainforest that ivorensiz a short dry season. In Gabon 4-month-old seedlings have been planted after clear-cutting of the forest, and in other sites after removal of the forest undergrowth and thinning of the upper canopy. It is threatened by habitat loss. The wood is in demand for making backs or sides of acoustic guitars as it is considered to have good acoustical characteristics.
Regular thinning of the shade trees in the first years is needed for good growth of the Khaya ivorensis trees. Ivordnsis southern Cameroon on average 0. Articles lacking in-text citations from March All articles lacking in-text citations Articles with ‘species’ microformats Taxonomy articles created by Polbot.
This may be partly due to some genetic resistance against Hypsipyla robusta attack. The seeds are best sown in seed beds in the nursery. The oil can be used as an ivorensie in liquid soaps, and may act as an antibacterial and antifungal agent because of the presence of limonoids such as methylangolensate.
The seed weight viorensis — g. Khaya iovrensis wood is exported from West African countries in mixed consignments with other Khaya spp. The sapwood is often removed soon after felling to prevent attacks by ambrosia beetles. Root pulp is applied as an enema to treat dysentery. The bark of saplings is sometimes eaten by porcupines and squirrels, which can kill the plants. Provenance trials in Ghana showed ivrensis fairly high heritability for height growth, with the growth of the highest-ranking progenies being nearly twice that of the lowest-ranking ones.
The wood holds nails and screws well and glues satisfactorily. The bark showed anticonvulsant activity in mice. It turns fairly well. It belongs to subfamily Swietenoideae and seems most closely related to Carapa and Swietenia. This page was last modified on 20 Decemberat The combined effects of selection of provenances with genetic resistance and appropriate silvicultural practices could have a substantial positive impact on the damage caused by Hypsipyla robusta stem borers.
Khaya ivorensis typically grows in drier climates.
The integration of Khaya ivorensis in agroforestry systems, as is already the case in cocoa based systems in Nigeria, can be considered economically and technically feasible and an ecologically sound strategy. The boles of Khaya ivorensis trees are occasionally so large that they cannot be sawn with normal equipment.
Extensive lateral growth starts when the upper canopy of the forest has been reached. In plantations Khaya ivorensis may suffer seriously from Hypsipyla robusta shoot borers that kill the main stem of young trees, causing excessive branching and contributing to mortality. Khaya ivorensis is a species in the African mahogany family. It is also used as fuelwood and for charcoal production.
Khaya ivorensis is included in the IUCN Red list as a vulnerable species because of habitat loss and degradation, and selective felling. It is mostly found in West Africa and southern Nigeria.
This article includes a list of referencesbut its sources remain unclear because it has insufficient inline citations. Germination is rather slow, taking 11—40 days. Management under the tropical shelterwood system seems most appropriate. It has been proposed for inclusion in CITES appendix I or II, but it has not been listed due to insufficient information on regeneration, extent of plantations and sustainability under current management regimes. Some find that when mixed with black peppercorns it can beused to treat diarrhea and dysentery.
It grows many white flowers at the end of its branches.
