Hi
I was wondering whether the property owners have considered trimming off the dangerous branches that could fall, and leaving a safe sized trunk into which hollows are carved for wildlife to use. Tree hollows are in short supply because they take more than 100 years for a parrot sized hollow to form, and more than 200 year for a hollow large enough for an owl or a possum to nest in. A trunk of a dead tree is a wonderful resource to use in this way.
There is a tool called a Hollowhog which can be used to make a deep hollow with a relatively small entrance, which can be seen here:
