Information on forest structures are fundamentally important to keep track of successional vegetation dynamics for efficient forest management. This study reports on vegetation characteristics, dominance patterns and species height growth in a Northern Mistbelt forest type in South Africa. Common alpha-diversity indices (species richness and Shannon diversity), structural vegetation parameters (tree density and basal area) and species importance value index were used. Size class distribution and height-diameter allometries were further examined for the overall stand and dominant species. Stem densities (472±43.46 and 605.33±28.10 treesha-1 for 5–10 cm and ≥10 cm dbh classes, respectively) and basal area values (1.99±0.19 and 48.07±3.46 m2ha-1, respectively) are comparable to other Afromontane forests in East Africa. The overall stand showed an inverted-J shaped distribution pattern which is typical feature of stand size class distribution in most natural forests. Most ecologically important species also exhibited an inverted-J shaped distribution pattern, suggesting good regeneration and recruitment potential. There were significant effects of species on tree height, reflecting species-specific patterns in height growth, probably a result of intrinsic growth potential and competitive interactions. The present study suggests that conservation and management policies, including protection of surrounding land uses against fire, contributed to maintain a successful recovery of these forests. However, it should be taken into account that these forests may be experiencing relatively slow dynamic flux as a result of the over-mature state of some trees with several years under relatively strict protection.
