Spatial Distribution of selected Tropical Hardwood Species in a Strict Nature Reserve, Ondo State, Nigeria

Spatial data indicating the processes and patterns of some tropical hardwood species stands are still limited. The aim of the study was to identify, represent and analyze the spatial point pattern of these tree species within the study area. Four sample plots (50 m x 50 m) were laid alternatively on each transect within the Strict Nature Reserve. In each plot, trees with DBH ≥ 1.3 cm were identified, measured alongside their respective individual (x, y) perpendicular distances from the point of identification to the sample plot boundary in meters. The result of the G-function of Funtumia elastica from this study reveals a clustering pattern when at a spatial range r from 0-1.5 with the distribution of Baphia nitida, Celtis zenkeri, Mansonia altissima and Sterculia rhinopetala following a random pattern. The F-function agrees with a clustering pattern for Funtumia elastica, Mansonia altissima and Sterculia rhinopetala and aligns with a regular pattern for Baphia nitida and Celtis zenkeri. The K-function resulted in a random pattern for Baphia nitida and Celtis zenkeri, clustering pattern for Funtumia elastica and clustering pattern at r range 10-12 and r=4 for Mansonia altissima and Sterculia rhinopetala respectively.
