Cortaderia selloana can become a fire hazard and exhibit sharp leaves that can cut epidermally and limit recreational use.
The rapid growth rate and lack of dormancy period contributes to S. densiflora successful invasive patterns within Brazil.
[8] Invasive grass can influence native plants by dissipating their nutrient supply, as well as causing an imbalance within the ecosystem's infrastructure.
[9] The attempt of controlling and preventing the growth of invasive grass would substantially improve the state of neighboring organisms, however it has proven quite difficult to achieve.
Recent studies have examined whether the presence of the disturbance of these forms of grasses have caused the extinction of native species in Brazil.
For example, in Parque Nacional de Brasília (National Park of Brasilia), two methods of control management were tested to determine what could possibly remove the invasive outbreaks of Melinis minutiflora.
The second method tested involved a combination of fire, herbicide sprays and manual removal, the conductors calling it “integrated management”.
Although this strategy worked to control M. minutiflora, it is not significant enough to consider since the recolonization and growth rate dominates the process of integrated management.
