Palani Hills

Plantation paradox

Print edition : November 13, 2015

The upper Palani Hills have a landscape dominated by exotic tree plantations, but there are important remnants of the shola/grassland mosaic vegetation type still in evidence. Plantations have, in fact, become shola nurseries. Photo: IAN LOCKWOOD

Clear-felling of plantations near Berijam Lake and Madikatan Shola. Taking out plantations like this invites a proliferation of weeds and does not return the landscape to the original shola/grassland mosaic. Photo: IAN LOCKWOOD

New Wattle sapling. When plantations are clear-cut, the result is usually a profusion of weeds and thousands of young wattle trees. Photo: IAN LOCKWOOD

EucalyPtus and montane grasslands on Perumal Peak. This is an area optimal for restoration since much of the grassland is still intact. Photo: IAN LOCKWOOD

Montane grasses in eucalyptus forest. Many plantations in the Palani Hills still show evidence of their historical vegetation. These montane grasslands have survived somehow on the slopes of Perumal Peak. Areas like this are ideal for careful restoration efforts that allow the grasses to make a comeback. Photo: IAN LOCKWOOD

Calanthes triplicata. Biodiversity in sholas is very high with numerous species of trees, shrubs, epiphytes and other organisms such as this ground orchid. This diversity is spreading into exotic plantations that are next to sholas. Photo: IAN LOCKWOOD

Water workers. Healthy grasslands play a key role in the hydrology of the hills and ensure water to farmers such as these near Poondi, an agricultural settlement in the north-western Palani Hills. Photo: IAN LOCKWOOD

Restoration work in a montane grassland is a difficult and labour-intensive task. The job is easier if pre-existing grasslands can be protected and allowed to flourish where plantations are invading their area. This image is from a VCT-FD pilot project near Kodai's golf course. Photo: IAN LOCKWOOD
