Ecological Impact

While Eucalyptus globulus provides economic benefits, its introduction outside its native range has led to ecological concerns. The species can become invasive, outcompeting native vegetation and altering local ecosystems. It is known to reduce biodiversity and affect water availability due to its high water consumption.

Cultivation

Eucalyptus globulus is cultivated in plantations for its rapid growth and high yield. It prefers well-drained soils and a sunny position. The tree is relatively drought-tolerant once established but benefits from regular watering during dry periods.
