Evaluate the adaptability of Eucalyptus species in the highlands of the Amhara region

Abstract

The predominant cultivation of Eucalyptus globulus in the highlands of the Amhara region poses a significant risk, as any disease/insect outbreak affecting this species could result in extensive barren lands across the country. Therefore, the study aimed to explore the adaptability of various Eucalyptus species to diversify and safeguard against potential ecosystem disruptions. Six different Eucalyptus species (E.globulus, E.camaldulensis, E.grandis, E.saligna, E.viminalis, and E.citiodora) were subjected to a Randomized Complete Design with three replications. All the required parameters were measured and analyzed using descriptive and inferential statistics with R version 4.3.1. Statistically significant variations were observed between Eucalyptus species at P < 0.001 in height, survival rate, volume, and mean annual increment. In conclusion, E.viminalis, E.saligna, and E. grandis are viable alternatives for Eucalyptus growers in Wadela and similar highland areas of Ethiopia. This research underscores the importance of diversifying Eucalyptus species to enhance resilience and sustainability in the face of potential threats to the dominant species, Eucalyptus globulus.
