i) Choosing the site

Decide on the aim of the revegetation project and consider how appropriate revegetation is on each prospective site. Is your area natural grassland in which case trees may struggle to survive long term?
Often revegetation projects are planned for less productive sites such as hilltops, waterlogged areas or sensitive sites such as banks of watercourses, and along roads and fence lines.
If there is stock, the site will need to be fenced or otherwise protected during establishment, but you will then not need individual tree guards. Consider the possible linkages to existing native vegetation or revegetation corridors in your area.
