| Effect of pines removal and soil litter treatments in the restoration of natural grasslands invaded by Pinus halepensis. Ernesto Tornquist Provincial Park (Sierra de la Ventana, Buenos Aires, Argentina) protects a remnant of pampean grasslands and is seriously threatened by the spread of alien woody plants, among them by Pinus halepensis. The effect that this species has on the structure and functioning of the ecosystem lead to the implementation of control actions aimed to reduce invasion. This work presents the results of monitoring the recovery of native grasslands after two control strategies: complete and partial removal of invasive trees, with and without complementary restoration actions (removal of needles, soil disturbance, addition of top-soil... |
