In southern Australia, revegetation

and regeneration activities have been

happening for a long time. Despite this,

people are still trying to understand

the ecological processes that sustain

or degrade native vegetation remnants

in agricultural landscapes. In northern

Australia we are even further behind.

Revegetation and regeneration weren’t

really seen as important until the recent

expansion of different land uses began

having a significant impact on native

vegetation. In this chapter there are

some best-bet guidelines gained from

previous experience in northern Australia

that you can implement and build on. In

bureaucratic-speak this is called adaptive

management.

Revegetation and regeneration

6

Planning and designing your revegetation or regeneration project is not just about

planting trees or managing an area of bushland willy-nilly. You need to know where

to concentrate your efforts with regard to the broader landscape. More about this

topic can be found in the planning section starting on page 152. An introduction to

revegetation and regeneration models and methods is also provided, with nitty-gritty

technical detail given in later sections relating to:

• Revegetationusingseedlings–thegrowingphase.

• Revegetationusingseedlings–theplantingphase.

• Revegetationusingdirectseeding.

• Thenaturalregenerationmethod.

• Seedcollection,cleaningandstorage.

• Nativegrassseedharvesting.

• Revegetationusingnativegrasses.

• Minesiterevegetationandecosystemrestoration.

• Monitoringandevaluation.
