Weed Control is an imperative part of ecological restoration. Knowing which plants are weeds and how to control them effectively is essential for successful restoration outcomes.
Weed control needs to be done methodically, with initial primary work followed-up on a regular on-going basis. The amount of time required for primary and follow-up weed control will depend on the control methods used, the type and density of weeds found on the site, the soil type, rainfall, and time of year.
The most serious weeds are climbing vines like Madiera Vine (Anrediera cordifolia) and Cat’s Claw Creeper (macfadyena unguis-cati), that can smother the canopy and should be prioritised for removal if they are found on any site.
Weed control can be done without herbicide, using intensive hand weeding, and other non-herbicide control techniques, or by using herbicide, or a combination of both. Most local weeds can be controlled using the least toxic herbicides in minimal amounts.
Non-herbicide methods are generally slower and more labour intensive but can be an option for those wanting completely chemical free, organic land repair. Most bush regeneration is done using herbicide as it is usually a more cost effective and speedy process.
Once an area has had the initial intensive weed control done,where most herbicide use occurs, the amount used declines over time, until very minimal, or no amounts are required.
Good bush regenerators know what, when and how to use herbicide safely and effectively, and how to control most weeds without herbicide.
