Revegetation
Cassia fistula has been reported to help revegetate overgrazed lands (Datiles et al., 2017).
Invasiveness
Cassia fistula produces large amounts of seeds that remain viable for more than a year, and is also able to propagate through cuttings and layering, and is tolerant of a wide range of soils and climate. It has been reported to be invasive in Queensland, Australia. It could have a negative environmental impact given its wide distribution range (Datiles et al., 2017).
