ABSTRACT
Quarrying for limestone is an economic necessity that is not only hazardous to human but also one that invariably has deleterious effect on the environment. Information on the performance of trees species is important as plants are key in the revegetation of exhausted quarries. A comparison of field performance of Acacia xanthophloea, Schinus molle, Casuarina equisetifolia and Grevillea robusta was made in an exhausted limestone quarry, backfilled with limestone mine waste, in a semi-arid area, in Athi River, Kenya, between 2005 and 2008. The aim of the study was to assess the performance of the above tree species and to determine if these tree species had an influence on the soil physical and chemical properties. The seedlings were produced in a nursery and transplanted in plots established in the exhausted quarry site using randomised complete block design. Growth performances were estimated by measuring; tree height, diameter at the stem base (BD), and diameter at breast height (DBH) from March 2006 to March 2008. The soils physical and chemical parameters measured were: moisture content; organic matter; pH; total Nitrogen; total Phosphorus and exchangeable cations. The study revealed that the time-species interaction was significant (p
