In a landmark move towards environmentally responsible infrastructure development, the National Highways Authority of India has announced the creation of the country’s first dedicated Bee Corridors along National Highways, marking a decisive shift from ornamental plantation practices to ecologically driven green infrastructure.
The initiative aims to establish continuous linear stretches of bee friendly vegetation comprising flowering trees and plants that provide nectar and pollen throughout the year. By integrating pollinator conservation into highway plantation strategies, NHAI seeks to address the growing ecological stress faced by honeybees and other pollinators, whose declining populations have direct implications for agricultural productivity, horticulture and overall ecological balance.
Ecology Driven Plantation Strategy
Under the Bee Corridor initiative, NHAI will realign its plantation activities to support pollinator habitats rather than focus solely on aesthetic landscaping. The corridors will feature a carefully curated mix of trees, shrubs, herbs and grasses designed to sustain pollinators across seasons.
The approach will retain natural elements by incorporating nectar and pollen rich species, allowing flowering weeds to bloom, and preserving dead wood and hollow trunks that provide nesting and resting spaces for bees and other beneficial insects. Plant species will be selected to ensure staggered flowering cycles, maintaining near continuous blooms throughout the year.
Native species identified for plantation include Neem, Karanj, Mahua, Palash, Bottle Brush, Jamun and Siris. These species are known for their ecological compatibility, flowering characteristics and suitability across diverse agro climatic zones.
Strategic Corridor Planning
Depending on agro climatic conditions and local suitability, Bee Corridors will be developed along selected National Highway stretches and on vacant NHAI land parcels. Field offices across the country have been tasked with identifying suitable highway sections for implementation.
Clusters of flowering trees will be planted at intervals of approximately 500 metres to 1 kilometre, corresponding to the average foraging distance of honeybees and wild bees. This spacing is intended to create connected pollinator pathways, enabling sustained feeding and habitat access.
NHAI field offices will develop at least three pollinator corridors during 2026-27 as part of the initial phase of the programme.
Scale Of Plantation Drive
During the financial year 2026-27, NHAI plans to plant around 40 lakh trees along National Highways nationwide. Approximately 60 per cent of these plantations will be undertaken under the Bee Corridor initiative, integrating pollinator friendly species into large scale roadside greening efforts.
The initiative represents a structural reorientation of highway landscaping, embedding biodiversity objectives within infrastructure expansion.
Ecological And Agricultural Impact
Pollinators play a critical role in crop production and ecosystem health. Declining bee populations have raised concerns globally due to their impact on pollination services and food systems. By transforming highway corridors into ecological assets, NHAI aims to contribute to biodiversity restoration while supporting agricultural and horticultural productivity.
The Bee Corridor initiative is expected to enhance ecological outcomes, improve habitat connectivity and reinforce NHAI’s commitment to sustainable and climate responsive infrastructure development.
With this programme, India’s highway network is poised to serve not only as a transport backbone but also as a functional ecological corridor supporting pollinator conservation at scale.
