The Knowledge Transfer (KT) system for arborists in Ireland is designed to improve professional standards, enhance safety, and promote sustainable tree management practices.

It was implemented by Galway and Roscommon Education and Training Board (GRETB) in January 2024 and – with 15–20 KT events per annum – facilitates continuous learning and collaboration among arborists, industry organisations, academic institutions, and government bodies. Key stakeholders include the Arboricultural Association (Ireland Branch), Coillte, the Health and Safety Authority, the Department of Agriculture, Food and the Marine (DAFM) Forest Service (forest protection), ESB Networks, the National Parks and Wildlife Service, the Office of Public Works, Teagasc Forestry Development Department, University College Dublin, Atlantic Technological University, and private sector ecologists, consultant arboriculturists, and landowners. By integrating research with practical applications, the KT system ensures arborists are aware of new technologies, regulatory compliance, and environmental stewardship practices.

Aims

As Ireland continues to place greater emphasis on environmental conservation and urban forestry, arborists must stay updated with the latest industry techniques, policies, and scientific advancements. The KT system facilitates professional development and peer-to-peer knowledge sharing, ensuring that arborists are well-equipped to manage Ireland’s diverse tree population responsibly and efficiently.

The system also aims to foster a culture of continuous improvement within the arboricultural sector by encouraging research, innovation, and best practices. The integration of academic research and practical applications ensures that arborists can access scientifically backed knowledge to enhance their skills and services. Furthermore, it seeks to build stronger networks among arborists, policymakers, state agencies, and arboriculture/forestry organisations to encourage collaboration on tree management initiatives.

Objectives

The objectives of the KT system include enhancing professional skills, improving safety and compliance, promoting environmental stewardship, encouraging research and innovation, and facilitating knowledge sharing and collaboration. Events cover essential arboricultural skills such as tree pruning, disease identification, risk assessment, and safe work practices, while also introducing arborists to emerging technologies and current research.

Ensuring arborists adhere to national and EU safety regulations and best practice guidelines is a priority. The system also guides arborists on ecological principles and biodiversity conservation to enhance their role in urban and rural landscape management while encouraging the use of sustainable tree care practices that support carbon sequestration and climate resilience.

Bridging the gap between academic research and practical applications is another key objective, which is achieved through collaboration with universities and research institutions. Supporting trials of new arboricultural techniques and materials, such as biochar for soil improvement and alternative pest and pathogen control methods, will further contribute to industry advancement. Additionally, a platform for arborists to share experiences, case studies, and solutions to common challenges has developed, strengthening industry networks and fostering relationships between arborists, government agencies, and other interest groups.

Participation

Participation in the KT system is free and open to all arborists in Ireland, from beginners to experienced professionals, as well as stakeholders involved in tree care and management. The initiative is designed to be inclusive and accessible, ensuring that knowledge dissemination benefits the entire industry.

Individual arborists, including self-employed professionals and employees of tree care companies, can engage in workshops, seminars, and demonstrations. Industry organisations and associations such as the Arboricultural Association (Ireland Branch), the Society of Irish Foresters, and the Tree Council of Ireland play an active role in shaping training content and standards, ensuring alignment with industry needs and best practices.

Research and educational institutions, including universities and Teagasc Forestry Development Department, contribute research findings and provide locations for field days. Student arborists at GRETB benefit from guest lecturers, workshops, and visits to case-study properties to gain hands-on experience. Government agencies and local authorities responsible for urban forestry, park management, and environmental protection can leverage the KT system to upskill their staff and promote best practices in public tree care.

Coillte, the Health and Safety Authority, the DAFM Forest Service, ESB Networks, the National Parks and Wildlife Service, the Office of Public Works, Teagasc Forestry Development Department, University College Dublin, and Atlantic Technological University (Connemara) will all play crucial roles in shaping and supporting the KT system. These organisations bring expertise in tree pathology, safety regulation, ecological research, historic property management, and arboricultural education. Private sector ecologists and consultant arboriculturists will also contribute by sharing best practices and offering professional insights.

Private sector participants, such as landowners, developers, and businesses with significant green spaces, also benefit from KT initiatives by learning sustainable tree management practices. Collaboration with commercial entities has driven investment in innovative tree care solutions, further enhancing the industry’s capacity for responsible arboriculture.

Outcomes

The implementation of the KT system is yielding several positive outcomes for the profession and the environment. Arborists now have access to up-to-date knowledge and information, leading to improved tree care standards across the country. The adoption of modern arboricultural techniques will enhance efficiency and effectiveness in tree maintenance and preservation. Additionally, stronger industry networks are emerging, fostering enhanced collaboration between arborists, academics, and policymakers, resulting in a more cohesive and well-supported profession. Better communication and knowledge exchange will lead to more effective responses to tree health issues and climate change challenges. Furthermore, increased public awareness and engagement are also encouraged through outreach components designed to educate communities about the importance of trees and proper tree care. More informed landowners and citizens will contribute to better tree management and preservation efforts.

Conclusion

The Knowledge Transfer system is an essential initiative to ensure the long-term sustainability of the profession and the health of the country’s trees. By focusing on professional development, safety, innovation, and environmental stewardship, it is empowering arborists to make informed decisions and implement best practices in their work. The success of this initiative is founded on strong collaboration among arborists, industry bodies, educational institutions, and government agencies. Ultimately, a well-structured KT system will contribute to a more skilled workforce, healthier urban and rural tree populations, and a greater appreciation for the vital role that trees play in Ireland’s landscape.
