This workshop will provide you with a general knowledge base in the fields of tree risk assessment and forest management. The first part of the course is designed to inform and instruct participants about tree risk assessment techniques, preserving the urban canopy and use of safety equipment/personal protective equipment (PPE) to minimize risk and avoid injuries during production work. Forest health issues and their management across Oregon’s forests will also be discussed. Issues ranging from native insects and diseases to new exotic pathogens will be brought to light, and we will explore how the Forest Health Program manages these issues across State Lands. Participants will learn about tree problems in parks and urban areas and some possible solutions you can use. Lastly, there will be a segment on dormant pruning and how this can help you to prevent future issues with trees. Come and meet three extremely qualified forestry professionals and learn how they best manage tree risk in their agencies, and how you can help your agency or company do the same.
