Figure 2

Fine root biomass vertical distribution (t ha ^-1 ) for three soil depths (0–20, 20–40 and 40–60 cm) for three different riparian land uses at four sites. Site × Land use interaction is significant at p < 0.001 for the 0–20 cm and 20–40 cm soil depths, and at p < 0.05 for the 40–60 soil depth. Horizontal bars represent SE.
