| Тойм: | The natural forest of Onigambari forest reserve was enumerated between the month of June to November, 2019 for its height and diameter class distribution and basal area. Systematic cluster sampling technique was used to allocate sample plots. 200m × 500m area referred to as clusters and partitioned into 100m × 100m tracts, each tract was separated at 20m interval from the other. The clusters were located within the reserve where human interference on the vegetation were relatively low. In each of the sample plots tree species ≥ 10 cm DBH were enumerated and recorded. Out of the thirty-five species enumerated, Triplochitin scleroxylon was the most abundant species, followed by Strombosia postulata. 10% of the entire tree stands were found with heights greater than 30 m height and 33% had heights that ranged between 5m < 10m. This means that the forest is underdoing recovery. 65% of the trees had DBH that is less than 20 cm which further confirms that most of the tree species were young and slender. The status of the tree species in the study plot were accessed based on their relative densities. 5.7% of the tree species were abundant with Triplochitin scleroxylon being the most abundant species in the study plot. The structure of the forest depicted a forest striving to survive after a major disturbance. Anthropogenic activities should be greatly prevented in order to maintain the ecological function and encourage natural forest regeneration in the forest |
