 Urban development, agriculture, and infrastructure is increasingly fragmenting the required habitat for these species and they are therefore more reliant on protected areas.Even species such as the Powerful Owl ("Ninox strenua") that can tolerate some habitat fragmentation still rely on available tree hollows for nesting and the availability of prey.Forest dependent species such as the marsupial gliders and ground dwelling mammals are relied on for food by owl species, therefore reduction in the abundance of prey due to habitat fragmentation is an indirect impact on owls.
