A Preliminary report on a long-term permanent sample plot in the lower dry evergreen forest in Kuiburi national park
A permanent sample plot was established in Kuiburi national park, in an area covered by lower - dry evergreen forest. The plot is utilized for different purposes, such as ecological studies, forest dynamics monitoring and climate change impact. The plot measures 120 x 120 meter. The plot’s size was chosen based on the resolution of the satellite images utilized. The plot was then subdivided in 144 subplots (10 x 10 meter).
During the surveys were counted 2,975 trees belonging to 47 species included in 24 families. Trees height ranges from 4 to 16 meter, with a canopy characterized by 3 layers. The study found an L-shaped diameter class distribution. The tree basal area is 28.40 m2/ha and the tree volume is 266.90 m3/ha. Diversity indexes have also been calculated. The Shannon-Wiener diversity index measures 2.24, Simpson’s diversity index 0.78 and the Evenness index for tree 1.34. Biomass and carbon stock in trees within the plot are, respectively, 148.60 and 69.84 tons.
