Senna spectabilis has taken over between 800 and 1,200 hectares of the buffer zones of the Mudumalai Tiger Reserve (MTR) in the picturesque Nilgiris hill district.
- 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.
- The Forest Department is coming up with a comprehensive strategy to deal with the spread of the invasive species, which continues to spread rapidly in the buffer zone.
