Impact TypeHabitat Alteration
Study TypeExperimental
Study LocationField
Impact DescriptionAbove-ground biomass, below-ground production, soil elevation, and the expansion of the root zone decreased due to Nutria (Myocastor coypus) herbivory. Litter production, the rate of soil surface accretion, and shallow soil subsidence were all higher in grazed vs ungrazed plots, while soil organic matter and bulk density did not differ significantly between treatments.
Reference33934
NotesThese results indicate that herbivores can have a negative effect on soil building processes, primarily by reducing below-ground production and expansion of the root zone.
