tree hollows
Natural wood cavities
Tree hollows are cavities that form in living or dead trees, typically where branches have fallen or decay has set in.
These natural spaces provide essential habitat for wildlife—owls, possums, bats, and countless other species nest or shelter in them.
Because hollows take decades to develop, their loss through logging or land clearing poses serious conservation concerns: The forest lacks mature trees with hollows suitable for breeding pairs.
