- Pampas is an aggressive environmental weed.
- There are three species of pampas in Tasmania: Cortaderia selloana, common pampas grass, C. jubata, pink pampas, and C. richardii,

Pampas in Tasmania
- Pampas is widespread in Tasmania (see map), occurring in coastal and bushland vegetation, silvicultural operations, quarries, neglected areas, road and rail corridors, and creek and swamp verges. Pampas is also found in gardens and as wind-break plantings.
- Pampas can rapidly colonise disturbed or burnt areas in a range of vegetation types from coastal scrub to closed wet forest, where it readily out-competes native vegetation. Pampas is problematic for the forestry industry, and can impede access along roads, walking tracks and coastal recreation areas.
Pampas is also highly flammable and poses a significant fire hazard.
