Green Revival in São Paulo: Nurseries Cultivate Urban Biodiversity

In São Paulo, Brazil, a remarkable green initiative is underway. The city's three municipal nurseries are producing about 1.5 million native seedlings annually, aiming to rejuvenate the urban landscape. The Harry Blossfeld nursery, in particular, stands out by cultivating over 270,000 seedlings from more than 200 tree species, including 22 that are on the brink of extinction.

These nurseries are not just about beautifying the city; they are vital for scientific research and knowledge production about native plants, many of which are little-known.

Their work contributes significantly to urban afforestation, helping to recharge aquifers, combat heat islands, prevent flooding, attract wildlife, improve air quality, reduce noise pollution, and enhance the emotional and physical well-being of city residents.

The seedlings grown in these nurseries are used for landscaping, enriching city parks, and urban reforestation initiatives. Schools also benefit from these seedlings, with nearly 10,000 trees planted in educational centers in underprivileged areas.

The nurseries' approach emphasizes the importance of native species and biological diversity in urban tree planting. This not only restores ecosystems and rescues original species but also provides diverse food sources for native wildlife, aiding reforestation efforts.

The process in the nursery is comprehensive, starting from seed collection to the final stage of planting. The focus is on native species that offer environmental benefits but are not economically valued or are endangered. This approach allows municipal nurseries to prioritize biodiversity over commercial interests.

São Paulo's municipal nurseries are more than just plant-growing facilities; they are hubs of environmental restoration, scientific research, and guardians of the city's natural heritage.

Their work in bringing rare and forgotten trees back to life is a testament to the power of urban greening initiatives in transforming cityscapes and conserving biodiversity.
