In addition to the dominance of indigenous plant species, the grasslands of Nilgiris harbour a considerable number of exotic plants with sizeable number of individuals. In the present study in four major grasslands of Nilgiris, out of 12 exotic species present, 10 are recognized as medicinally important. The family, Asteraceae contributed a higher number of 6 medicinal species to the grassland community. The density of exotics in the studied grasslands is varied between 4 and 66/ha. In order to conserve the native species, the frequent harvesting of useful parts of exotics is suggested. In addition cultivation of these exotics in the degraded grasslands and other suitable habitats in Nilgiris may also reduce the pressure upon the native species and at the same time it will also meet the demand.
除了本土植物物种占主导地位外,尼尔吉里斯的草原还生长着大量数量可观的外来植物。在本次对尼尔吉里斯四大草原的研究中,在现存的12种外来物种中,有10种被认为具有重要药用价值。菊科植物为草原群落贡献了数量较多的6种药用植物。研究的草原中外来植物的密度在每公顷4至66株之间。为了保护本土物种,建议对外来植物的有用部分进行频繁采收。此外,在尼尔吉里斯退化的草原和其他合适的栖息地种植这些外来植物,也可能减轻对本土物种的压力,同时还能满足需求。
