CTD through its Plant and Wildlife Domestication sub-programme conducted successful trails. It was concluded that rooting leafy vine cuttings provides the optimum means of Eru multiplication and could be grown successfully at its natural habitat with minimal inputs and encouraging yields. Most significantly, CTD developed the cultivation methods of Eru to allow farmers and growers to produce successful harvests. CTD has also established three Eru on-farm trials in villages around the Mount Cameroon in addition to private Eru farm near Yaounde.
CTD has organised a training workshop for 40 participants including University students, the Regional College of Agriculture and Forestry school, MINEF and Pandrillus staff. Over 150 farmers have now been trained in Eru cultivation.
CTD has conducted experiments with the best conditions for germinating Prunus africana seeds and has used this research to initiate several plantation trials, in collaboration with the International Centre for Research in Agroforestry (ICRAF) and Cameroon Development Corporation (CDC).
In the North West Province of Cameroon, a 1.5 hectare plantation of Prunus africana has been established by women in the Development Co-operation. Whilst in the South West Province, one thousand Prunus africana seedling were supplied to women in a Development Co-operation in the Fako Division.
Rattan has long been recognised as having a potential role in the world market. It's cultivated in parts of SE Asia, but exclusively harvested from the wild population in Africa. In 1995, CTD developed a living Rattan collection in The Gardens, represented over 60 % of known species, to monitor changes in morphology as the plants developed. In collaboration with Cameroon Development Corporation (CDC) and the African Rattan Research Programme (ARRP) a hectare of silvicultural trail of Laccosperma secundiflora was planted beneath absolute rubber in 1998 and initial growth rates were encouraging. Further work on the Taxonomy, Ecology and Utilization (revised), of Rattan can be obtained from africanrattanresearch@fsnet.co.uk.
