Data from: Predation risk landscape modifies flying and red squirrel nest site occupancy independently of habitat amount
Habitat choice often entails trade-offs between food availability and predation risk. Understanding the distribution of individuals in space thus requires that both habitat characteristics and predation risk are considered simultaneously. Here, we studied the nest box use of two arboreal squirrels w...
