Revegetation and Landscaping
With a long history of revegetation and landscaping around the state, our website now offers the capabilities to display this information in a easy to use map or list view. Filter locations by;

Landscaping refers to the hard and soft surface treatments applied along the back of kerb and road shoulder areas, suited to the location.
It is often implemented on larger projects or for works in high profile areas. These areas will have a higher standard of ongoing maintenance and may include other landscaping elements i.e. planting beds, turf, reticulation, decorative gravel and/or mulches.
- Typical hard landscaping treatments include paving, concrete, compacted or bound gravel.
- Typical soft landscaping treatments include organic mulch, grass and plantings of seedlings and native plants.
- incorporate the road into the surrounds (physically and visually).
- improve the visual amenity of the road reserve.
- provide a focal point or sense of place.
Revegetation refers to the direct seeding and planting seedlings of local native plants and trees along the road reserve.
It is used on both small and large projects, with traditional techniques of seeding and/or planting native seedlings back into a disturbed area.
In certain climatic and geographic locations, rehabilitation works may be limited to reshaping of the soil surface to promote plant growth. The Rip and Respread of topsoil method allows the regeneration of natural vegetation to occur.
This technique is typically used for material pit rehabilitation and projects that employ topsoil management for their rehabilitation strategy. This technique is mainly used in the state’s north (Pilbara and Kimberley). The correct management of topsoil is crucial to the success of this technique.
- Topsoil respread is spreading site topsoil and mulch, consisting of chipped vegetation from the site around the project area.
- Ripping is the ripping of the topsoil subsoil layers to promote growth and seed dispersion.
Occasionally, seedlings will be combined with the Rip and Respread method to speed up the revegetation process.
A Wheatbelt Revegetation Bank is currently being developed to provide a central pool of offsets available for use by future Main Roads projects, where there are impacts on native vegetation classified as Wheatbelt Woodlands Threatened Ecological Community.

The offsets will be established in advance, primarily through re-establishing native vegetation within widened road reserves. The geographic coverage of the offsets bank is the natural distributional range of the Wheatbelt Woodlands TEC (Figure 1).

Information is available in the form of drawings and specifications for both landscaping and revegetation works.
For drawings these are broken into three categories; Standard Contract Drawings, Guideline Drawings and Presentation Drawings.
- Standard Contract Drawings can be found in our technical library under Standard Contract Drawings > Vegetation
- Guideline Drawings can be found in our technical library under Guideline Drawings > Vegetation > Revegetation and Landscaping
- Presentation Drawings can be found in our technical library under Presentation Drawings > Vegetation
The specification used for our landscaping and revegetation works is known as the 304 Specification and it too has three versions.
- 304 – Landscaping and Revegetation, contains the full suite of clauses and is used for larger projects and those with additional landscaping elements such as planting beds, reticulation and/or turf.
- 304 – Revegetation, is a reduced version for use in revegetation works and smaller projects with traditional seeding and planting techniques.
- 304 – Rehabilitation of Disturbed Areas (non planting), tailored for material pit rehabilitation and projects that employ topsoil management for their rehabilitation strategy.
