For example, changes in the chemical composition of Eucalyptus due to genome editing might affect herbivores or other species that interact with the tree. Long-term monitoring and field trials are often required to assess these potential impacts before genome-edited Eucalyptus can be approved for commercial use. Environmental impact assessments also consider the potential for genome-edited Eucalyptus to contribute to the development of resistance in pests and pathogens. This is particularly relevant when editing genes related to disease resistance, as there is a risk that pathogens could evolve resistance to the modified defenses, leading to new challenges in pest and disease management (Swanepoel et al., 2023). 7.3 Public perception and acceptance of genetically editedEucalyptus Public perception and acceptance of genetically edited organisms play a significant role in the success and adoption of new technologies in forestry. The public’s views on genome-edited Eucalyptus are shaped by a range of factors, including cultural attitudes towards genetic modification, concerns about environmental and health risks, and the perceived benefits of the technology. In many regions, there is a strong public apprehension about genetically modified organisms, including trees, due to concerns about their potential impact on the environment and human health. This apprehension can extend to genome-edited plants, even when the editing does not involve the introduction of foreign DNA. Public engagement and education are therefore critical to addressing these concerns and fostering a better understanding of the science and safety measures behind genome editing (Borrelli et al., 2018). Transparency in the development and regulation of genome-edited Eucalyptus is also essential for gaining public trust. This includes clear communication about the benefits of the technology, such as improved disease resistance and sustainability in forestry, as well as the measures in place to ensure environmental safety. Involving stakeholders, including local communities, environmental groups, and industry partners, in the decision-making process can help build support for the adoption of genome-edited Eucalyptus. Ultimately, the acceptance of genome-edited Eucalyptus will depend on how well these technologies align with public values and the broader societal goals of sustainable forestry and environmental stewardship. By addressing regulatory, biosafety, and public perception challenges, the potential benefits of genome editing in Eucalyptus can be realized, contributing to more resilient and sustainable forest ecosystems. 8 Implications for Forestry Management and Conservation 8.1 Implementing disease-resistant varieties in forestry practices The introduction of disease-resistant Eucalyptus varieties into forestry practices represents a significant advancement in the management of Eucalyptus plantations. By deploying genetically edited trees that are less susceptible to common pathogens, foresters can reduce the reliance on chemical treatments, which have environmental and economic costs. The implementation of disease-resistant varieties can lead to higher yields, improved wood quality, and increased economic returns, particularly in regions where Eucalyptus is a major source of timber and bioenergy. However, the successful integration of these varieties into forestry practices requires careful planning and management. It is essential to assess the local environmental conditions and pathogen pressures to ensure that the selected varieties are well-suited to the specific challenges of the region. Additionally, monitoring and management strategies must be put in place to detect and respond to any emerging threats, such as the evolution of new pathogen strains that could overcome the resistance traits introduced through genome editing (du Toit et al., 2020). Moreover, the adoption of disease-resistant Eucalyptus varieties should be accompanied by best practices in silviculture, such as maintaining genetic diversity within plantations, to prevent the spread of resistant pathogen
