We present a model of apparent competition, parametrized using empirical data, to predict habitat restoration efficacy

Habitat restoration has the potential to increase caribou densities by up to 2.51-fold.

Increases in caribou density can occur with minimal changes to wolf or moose density.

Incorporating the numerical feedback into simulations of foraging efficiency increased our understanding of the total response.

Simulated predator reductions increased caribou densities by more than twice the total response of restoration, suggesting restoration should be coupled with other direct management actions.
