Answer

North-facing slopes will experience more evaporation, leading to lower moisture content in the soil and, consequently, lower vegetation density. Conversely, south-facing slopes are in the shadow of the koppie, experiencing less evaporation, which results in higher moisture content in the soil and thus a higher vegetation density.
