Native plant germination database sows seeds of change
With nearly a third of India’s land degraded and a quarter facing desertification, restoring ecological balance is no longer optional; it’s urgent. A new tool — India’s first open-access database of native plant germination methods — makes that work more accessible.
Compiled by the Ecological Restoration Alliance of India (ERA-India), this database consolidates more than 1,000 seed-germination protocols covering 465 native species, including Aegle marmelos (wood apple), Ficus benghalensis (banyan), Hopea indica (Malabar ironwood), Justicia adhatoda (Malabar nut), Madhuca longifolia (mahua), Withania somnifera (ashwagandha) and Ziziphus mauritiana (Indian jujube).
The goal is clear: to democratise access to seed knowledge for scientists, nursery managers, students, and citizen ecologists alike. “One of the fundamental and most practical steps in ecological restoration is to create a native plant nursery. This database is the first step toward that goal,” says Paul Blanchflower, a conservationist and restoration practitioner who co-founded the Auroville Botanical Gardens and contributed to the database.
Why native plants matter
India has pledged to restore 26 million hectares of degraded land by 2030 under the Bonn Challenge. Native plants are central to that mission because they have evolved with local ecosystems, alongside insects, fungi, animals, and climate conditions. “Some withstand drought, others resist fire. Some hold riverbanks in place or grow from bare rock. Whatever the terrain — dry, wet, unstable, or rocky — there’s a native species ready to grow,” says Arjun Singh, senior project manager at ERA-India.A germinating Vateria indica seed.

Native trees are typically hardier, requiring less water and maintenance, and coping better with extreme conditions. Blanchflower notes that when cyclones struck near Puducherry, the first casualties were non-native Acacia auriculiformis, whereas native species from the tropical dry evergreen forest — such as Memecylon umbellatum and Manilkara hexandra — remained standing.
Yet despite these advantages, manually propagating native plants remains a challenge. In the wild, thousands of seeds are propagated and with time on their side. Restoration projects, by contrast, must make every seed count. Complicating matters further, many native Indian trees, shrubs, herbs and grasses are not commercially available, and germination techniques are often buried in field notes or shared only through informal networks.
