||One of the major reasons for reforestation failure using tropical species is
misunderstanding of the neighbourhood relationship within tree populations.
This study used the natural stand structures of Terminalia macroptera and
Pseudocedrela kotschyi, two socio-economically important species, to
design planting. A comparative analysis of the population structure of P.
kotschyi and T. macroptera in pure and mixed stands was performed.
However, results indicated that young T. macroptera individuals were
predominant in both stand types. In the same way, no significant difference
was found between diameter size classes with respect to stand types. Trees
showed weak density and a random pattern with the nearest neighbour
distances varying between 5.67 m (pure) and 7.01 m (mixed). P. kotschyi
young individuals were also found to be predominant irrespective of stand
type; yet, the diameter size class distribution revealed significant variations
with respect to stand type. Trees had a higher density and stronger clumped
pattern in pure stands as compared to mixed stands. The nearest neighbour
distances ranged from 2.97 m (pure) to 4.87 m (mixed). Our findings
highlighted the relevance of taking into account relationships between stand
composition and tree population structure while designing plantings.
