Abstract
Summary: The species composition of grasslands in southern Tsavo National Park (West), Kenya, was investigated using detrended correspondence analysis (DCA) and two‐way indicator species analysis (TWINSPAN). Both techniques indicated that, except for one site along a lake edge, all grasslands were relatively similar. Species abundances varied along topographic gradients but all sites were dominated by the same species, regardless of location in the study area or topographic position. The vegetational homogeneity in southern Tsavo West suggests that the grasslands are more strongly influenced by rainfall and soil, which are relatively uniform over the study area, than by fire, topography or other factors found to create vegetational heterogeneity in other parts of East Africa.Résumé: On a recherché la composition spécifique des savanes du sud du Pare National du Tsavo (Ouest) au Kenya en utilisant le detrended correspondence analysis (DCA) et l'analyse de l'espèce indicatrice à deux voies (Twinspan). Les deux techniques montraient que, sauf pour un site au bord d'un lac, toutes les savanes sont relative‐ment semblables. Les abondances des espèces varient selon un gradient topographique, mais tous les sites sont dominés par la même espèce, quel que soit le site dans la zone d'etude et la topographic l'homogénéité végétale du sud du Tsavo Ouest suggère que les savanes sont davantage influenceées par le sol et les pluies qui sont assez uniformes dans la zone d'étude, que par le feu, la topographie ou d'autres facteurs comme pour créer une diversité végétale dans d'autres régions d'Afrique de l'Est.This publication has 20 references indexed in Scilit:
