Overview

The mode of spatial distribution of Ficathoa laurifolia and Ocotea usambarensis species has been treated in the game reserve of Kalikuku, Lubero Territory. In order to reach the result, we have delimited a plot for each species and in which we have carried out the sampling of diameter critter at «DHP» of each target tree according to our criterion, and the distances which could separate the individuals as they moved closer to one another, following the method called: Nearest Neighbor Method. That means the method of the neighbor that in very near, of Clark and Evans. The results that we have found are the following. The aggregation clue R has given 0,86 for Ficalhoa laurifolia, 1,5 for Ocotea usambarensis and -3,6 for Piptadeniastrum africanum. After the application of test Z of spatial deviation, Z has given - 4,12; 12,6 and -3,6 respectively for restoring it and aggregate distribution and even Ocotea usambarensis towards unpredictable or aleatory distribution, Piptadeniastrum africanum as an aggregate. The diametric structure of the three species presents a curve in form of bell «Gauss» in the base classes to decline from the beacon classes presenting then a curve in form of reversed j, witness of a natural forest. The very great land surface for Ficalhoa laurifolia has been of 19,8398 m2 in the fourth class of diameter, 4,2398 m2 in the class for Ocotea usambarensis and 26,679 m2 of Piptadeniastrum africanum in the third class.
