Habitat installation
Habitat boxes
An older but effective solution to providing habitat space. Basic plywood boxes are often suitable for larger birds and marsupials and to suit a certain aesthetic appeal, although are poorly suited to an increasingly hotter climate. However, recently more advanced polymer hybrid models are becoming available that are able to insulate against significant heatwaves and even host multiple species of different sizes.
Bored hollows
Hollows are bored directly into the tree and held open using cross sections of the trees own tissue. Very good control over size is possible and these hollows are suitable for creating habitat for smaller native species such as rosellas, sugar gliders and even wood ducks - although larger habitats are certainly possible in the right circumstances. Recent research has shown these hollows have excellent thermal properties and are a good option for providing long term, survivable habitat in an increasingly heat wave prone climate.
Habitat trees
An increasingly popular and often cheaper, alternative to removal is the reduction of the tree down to a few central upright branches, ideally with hollow boxes and/or bored hollows in place. Often the tree can survive this process and enters a long decline or sensesence which can last decades. During this period it becomes increasingly suitable for colonisation by microflora in its deadwood and birds and marsupials in its hollows.
