Grow native species for highway landscaping, say experts

Mandi, December 5

While modern highways may offer a visually appealing uniformity, many botanists and environmentalists are raising concerns about the ecological cost of this approach.The future of medicinal plants and sustainable practices was discussed at the recent regional stakeholders meet of the Regional-Cum-Facilitation Centre (RCFC) Northern Region-1 sparking a conversation on the need to rethink the current trend of beautifying highways with ornamental and exotic plants.

Organised by the National Medicinal Plant Board (NMPB) under the Ministry of AYUSH in Chandigarh, the issue of highway landscaping took centrestage.

Dr Tara Sen, head of the Botany Department, Vallabh Government College, Mandi, stated that highway stretches, once vibrant with the seasonal beauty of native Himalayan flora, now predominantly feature non-native, ornamental species. For those who cherish the region' s rich botanical heritage, such developments are disheartening, as they reduce the habitat's ecological value and threaten local biodiversity.

"Instead of continuing with ornamental plants, experts are calling for the incorporation of native, multipurpose plant species in landscaping efforts. Native plants, which offer a variety of benefits, including food, fodder, medicine, and material, are not only better suited to the local climate but also support local wildlife. These plants can thrive in challenging environmental conditions while minimising maintenance costs and contributing to sustainable land use," she remarked.

"Among the recommended species are Butea monosperma (Palash), a sacred and medicinal plant; Phoenix species, offering food and fodder; and Myrica esculenta (Kafal), known for its edible fruit. Other varieties such as Taxus contorta, Rhododendron species and Hypericum species are also highlighted for their ecological and therapeutic value," said Dr Tara.

"The shift towards native flora would address growing environmental challenges like soil erosion, carbon sequestration and biodiversity conservation," said Narender Saini, an environmentalist.

Experts emphasise the need for sustainable development, particularly as North India faces an increasing frequency of natural disasters, including landslides and flash floods, linked to large-scale infrastructural changes.

"Incorporating native species into highway landscaping would not only enhance the aesthetic appeal of these roads but also nurture the environment and offer long-term ecological benefits. As we continue to expand our infrastructure, it is crucial to prioritise sustainable practices that maintain a balance between development and nature, safeguarding the planet for future generations," said Dr Tara.

"The call for a greener, more sustainable approach to highway beautification is a reminder of our responsibility to protect and preserve the natural heritage of the Himalayas and beyond," she said.
