Increased invasion of production system weeds
Impact
Production system weeds are plants (exotic and native) growing in an area where they are not wanted. Weeds compete with agricultural species, such as crops and pastures, for resources often reducing productivity. Weeds can also poison domestic stock when growing on pasture land. The occurrence of weed invasion is higher in areas where the soil has been disturbed or left bare. Weed seeds can be dispersed by wind, by water, on the coats of animals, in the faeces of animals and on farm machinery and vehicles.
Suggested indicators: Weed species+, Weed cover+
Increased invasion of production system weeds may be associated with:

| Increased competition and stress to agricultural species leading to reduced growth and productivity |
|
| Changed fauna habitat (food, shelter, etc) influencing native fauna present |
