Ligularia virgaurea, a toxic perennial weed, has become a dominant species in the heavily-grazed alpine meadows of the eastern Qinghai–Tibetan Plateau over recent decades. We investigated changes in soil biochemical properties associated with L. virgaurea spreading in grazed alpine meadows at three sites. Soil and root biomass samples were taken at depths of 0–8 cm, 8–16 cm and 16–24 cm from patches where L. virgaurea was dominant and from areas between L. virgaurea patches, with only other… CONTINUE READING
