The impact of deforestation on the miombo woodland regeneration. A case of Madziva Communal Area
MetadataShow full item record
This research was carried out to assess the impact of deforestation on the Miombo Woodland capability to regenerate itself after a disturbance in Mashonaland central province. Two areas (Kobe and Mt Dikitira forests) of Madziva communal area were used as sampling sites due to the historical evidence of deforestation. A total of six sampling plots measuring 400 square metres each were used for the assessment. Aerial photographic analysis was used to detect and monitor changes in woodland covers in all areas. Shannon Wiener’s Index was used to determine species diversity within the study area. Vegetation structure and densities data was compared using Student t-test and Kolmogorov-Sminorv was performed. The results revealed that miombo woodland cover is declining at a decreasing rate which contradicts with other researchers’ findings. Furthermore, results also revealed that continuous interference with the regeneration process of genera Brachystegia and Julbernadia spp which constitutes the chief pillars of miombo woodland. Mt Dikitira forest community has the highest tree species diversity with compared to Kobe forest and there is evidence of regeneration of miombo woody species taking place in both forests. The study recommended the implementation of strict controls on harvesting of woody species in Mt Dikitira and Kobe forest so as to avoid complete elimination of the miombo type of woodland. It is also a good initiative to consider these two forests as research forests that will restrict tree harvesting hence giving the species more time to regenerate.
