Effective Actions for Managing Rsilient High Elevation Five-Needle White Pine Forests in Western North America at Multiple Scales Under Changing Climates

This paper addresses the severe decline of High Elevation Five-Needle White Pine forests in western North America, primarily due to mountain pine beetle outbreaks, white pine blister rust, and altered fire regimes exacerbated by changing climates. The authors advocate for multi-scaled management interventions to promote resilience to disturbances and genetic resistance to white pine blister rust. The paper details the critical need for long-term programs like inventory, mapping, and research, alongside active restoration treatments such as mechanical cuttings and prescribed fires, and proactive tree-level measures like planting rust-resistant seedlings and protecting high-value trees, all while integrating climate change considerations throughout the planning and implementation process.
