Modelling scenarios for forest conservation through restoration following moose (Alces alces) disturbance
Hyper-abundant ungulates can act as a disturbance and hinder natural forest regeneration w hen they severely overbrowse vegetation. In Newfoundland ( Canada), hyper - abundant moose have suppressed balsam fir advanced regeneration producing alternate stable states. I integrated data from field obser...
