    • It is  an exotic tree and it was introduced as an ornamental species and for use as firewood from South and Central America.
    • It has become highly invasive in the Sigur plateau in both the core and buffer zones of the MTR.
      • Over the last few years, its bright yellow flowers have become more visible across the Tiger Reserve, with conservationists stating that the invasive weed has a negative effect on local biodiversity, crowding out native species and limiting food availability for wildlife.
