Soil-Vegetation Interrelationships in Isoberlinia Woodlands of Northwestern Nigeria
Isoberlinia woodlands in northwestern Nigeria were sampled in 280 quadrats (100 m2) regularly spaced along established transects from upper to lower slopes. Vegetation measurements included density, basal, area, crown cover and height of woody species ≥ 3m high. Also, total number of species and c...

| Achoimre: | Isoberlinia woodlands in northwestern Nigeria were sampled in 280 quadrats (100 m2) regularly spaced along established transects from upper to lower slopes. Vegetation measurements included density, basal, area, crown cover and height of woody species ≥ 3m high. Also, total number of species and canopy cover per plot, and species diversity were determined. Soil pits were systematically excavated along the transects, and soil samples taken from each horizon in each pedan, air-dried and analyzed for physical and chemical properties. Canonical correlation analysis (utilizing principal component scores of soil and vegetation components. Results showed a reciprocal relationship between plant size and silt, manganese and aluminium. There existed a positive relationship between plant height and species diversity, and soil reactions and nutrient status. Aluminium also related positively with plant density and canopy cover. Hence canonical correlation analysis identified soil variables which affect the vegetation components, thus suggesting that both soil and vegetation are interdependent. |
