Prevent weed spread: industry and recreation

There are things you can do to prevent the spread of weeds when undertaking subdivision, development or construction in the Northern Territory (NT).

You must closely manage the following to prevent weed spread and establishment: 

• hygiene procedures for construction equipment, vehicles and materials to ensure they do not carry weed seeds into new areas
• control of existing and establishing weed infestations.

How to prevent weeds

You must do all of the following to prevent the spread of weeds on or from construction sites: 

• map locations and densities of declared weeds and send the information to a Weed Management Branch
• use weed data to write a construction environmental management plan
• control weeds before you begin work
• make sure staff and contractors can identify declared weeds 
• inspect and clean equipment of weed seeds before you begin work
• where seeding weeds must be cleared, you must stockpile and bund plant material and top soil
• minimise disturbance to soil and native vegetation
• manage weeds until there is a change of land use or until land titles are issued.

What you must not do

You must not do any of the following on site:

• take or use dirty equipment or vehicles to remote locations
• do not drive through weeds, particularly when clearing vegetation or subdivision lines - where you cannot avoid weeds, clean your vehicles before moving them to weed-free areas
• do not import or export contaminated material including sand, gravel, rock and fill.
