Basal area growth rates for Prosopis glandulosa were quantified for contrasting
landscape elements in a subtropical savanna. We hypothesized that growth
rates of P. glandulosa plants (1) are a function of seasonal or annual rainfall; and
(2) vary with patch type and in the rank order observed for large trees. Prosopis
glandulosa growth was responsive to changes in rainfall (!0)974 cm2
