Besides these threats, the road will also put the 320 bird and 56 butterfly species found here at risk. Members of the Sauraha-based Bird Education Society have been visiting the area since the 1990s, and say it is a treasure trove for nature.
Bird species also include the Red-faced Liocichla (Liocichla phoenicea) a beautiful scarlet and brown bird that was thought to have become extinct in Nepal until it was re-sighted in 2016 after 178 years, by watchers from the Bird Education Society and the Nepalese Ornithological Union.
Eight of these birds were found at 1,600m on Chisapanitar, close to the planned route of the road. The Red-faced Liocichla has not been found elsewhere in the country, and is listed as critically endangered in the national red list of the birds of Nepal.
Twenty other threatened bird species have been sighted regularly in the forest, including the Little Spiderhunter (Arachnothera longirostra) which is dependent on wild bananas, and the Red-headed Trogon (Harpactesery throcepalus) a beautiful red bird that needs a habitat of trees with a thick growth of climbers and creepers.
Until recently, the indigenous Chepang people followed a nomadic lifestyle, living off the rich forests as hunter gatherers. As other ethnic groups migrated here, the Chepang started to take up a more settled life based on subsistence agriculture. But their terraces on the steep slopes do not produce enough food, and the Chepang still depend on wild food from the forest.
The new road will run through the prime forest area for wildlife and destroy their homes, as well as disturb the terrace farms.
There is an alternative route for the road from Mathillo Kaule to Gadi via Mayatar. It is a bit longer but would protect the forest and the village water supply.
The subtropical broadleaf forests of the Gadhi-Siraichuli IBA are of high quality and are now a rare and declining habitat in Nepal. They support great biodiversity and are an invaluable resource to local Chepang communities. The forest lies at the northern end of the Barandabhar Corridor that links Chitwan National Park to the Mahabharat forests, and is important for the north-south movement of animals in the Chitwan-Annapurna Linkage (CHAL) and Terai Arc Landscape (TAL).
Says conservationist Hem Sagar Baral: “Peoples’ livelihoods, including those of the Chepang, depend on the watershed and forests of this area. Development impacting wildlife here should not be tolerated as we have no other places like this one. What is left must be preserved in its full integrity.”
