Modelling the effect of habitat composition and roads on the occurrence and number of moose damage at multiple scales [PDF]

open access: yesSilva Fennica, 2019
We modelled the effect of habitat composition and roads on the number and occurrence of moose ( L.) damage in Ostrobothnia and Lapland using a zero-inflated count model. Models were developed for 1 km, 25 km and 100 km landscapes consisting of equilateral rectangular grid cells. Count models predict the number of damage, i.e.
