Knowing the window of opportunity for successful broad acre revegetation projects in lower rainfall regions (400-600 mm rainfall)
Time lines are critical when undertaking broadacre revegetation projects, particularly in rainfall regions less than 600 mm.
A time delay of 7-14 days can make the difference of success and failure.
The regeneration of plant species in a natural system will always occur following good wet events, and providing a healthy seed source is present and ground surface is free of debris. The practitioner must understand these factors when undertaking this important work.
This paper looks at the variables that will ensure good outcomes.
It shows rainfall regions, germination times versus ground temperature, ground moisture of certain species, and methods of treatment to shorten germination times. It also discusses the day/night light hours to ensure maximum germination time, and how you need to fit this in when undertaking a direct seeding project.
