  • This study examines the survival and growth performance of seven planted species by assessing plant species diversity/composition in an 8-year old mixed plantation stand dominated by planted indigenous trees in Ghana. 
  • The study area is a maize system that was interplanted with 6 indigenous species (Ceiba pentandra, Alstonia boonei, Terminalia ivorensis, Khaya ivorensis, Terminalia superba, and Pericopsis elata) and one exotic multipurpose tree species (Cedrela odorata) that were planted at a density of 278 trees ha-1. Ten 1000 m2 plots were established in the one-hectare.
  • Seedling survival was 85% or greater for all tested tree species. With the average DBH = 22cm and height = 8m for all species. In addition to high tree species-survival rate, they also grew well together in mixed stands. After 8 years, the most abundant species in the study plots were Chromolaena odorata and Cedrela odorata, which collectively represent about 54% of all species, represented in the plots. C. pentandra and A. boonei had similar growth rates to the fast growing exotic species (Cedrela odorata). 
  • However, there was inadequate recruitment to the sapling stage requiring some form of silvicultural management without which naturally regenerated stands of important economic tree species cannot be increased.
  • Based on these results the authors conclude that a wide diversity of indigenous tree species can colonize degraded forests once enhanced with a few economically desirable native tree species.
