**CHENNAI, INDIA (March 16, 2025)** – A new study published in *The Hindu* reveals the crucial role of pollinators in grassland biodiversity restoration and underscores the long-term commitment required for effective conservation. The research indicates that even after 75 years of continuous management, restored grasslands fail to fully recover the specialized pollinator communities found in ancient grasslands.
While plant diversity in restored grasslands reaches levels comparable to ancient grasslands after 75 years, the pollinator community lags significantly. Newly restored areas attract mainly generalist pollinators like flies and hoverflies, which often transfer pollen between different plant species, reducing pollination efficiency. Ancient grasslands, conversely, support a higher proportion of specialist bees and butterflies, leading to more effective pollination within plant species.
The study highlights the importance of prioritizing the preservation of ancient grasslands as reservoirs for specialized pollinators. Conservation efforts, the researchers conclude, must consider the crucial role of pollinator communities in the long-term success of grassland plant conservation. The slow return of specialized pollinators necessitates a significant shift in conservation strategies, emphasizing the need for long-term protection of existing, biodiverse grasslands.
