Rogue Basin Cohesive Forest Restoration Strategy

Rogue Basin Cohesive Forest Restoration Strategy

 

The forests of the Rogue Basin in southwestern Oregon have innate ecological value, provide diverse wildlife habitats, underpin the carbon and water cycles, and provide human communities with clean water, recreation, and other benefits. Landscape-scale forest restoration is needed to mitigate threats to these forests and surrounding communities from uncharacteristically destructive fires catalyzed by a century of fire exclusion, past destructive logging practices, and climate change. This report describes the collaboratively-derived Rogue Basin Cohesive Forest Restoration Strategy, which integrates resource assessments conducted by the Southern Oregon Forest Restoration Collaborative and partners to clarify the potential costs and benefits of landscape-scale forest restoration in the Rogue Basin.

This document integrates four foundational parts. First, we conducted a wildfire risk assessment to quantify current wildfire risk and provide indicators for evaluating alternative management scenarios. Second, we identified a suite of five landscape-scale management objectives and the relative value of mechanical treatments to achieve those objectives. Third, we generated mechanical treatment themes and their potential extents and derived outputs for the entire landscape, should mechanical treatments be implemented. Fourth, we compare three contrasting management scenarios of increasing treatment footprint across the Rogue Basin and estimate their performance on key indicators. Finally, we discuss how these assessments could be used to inform project development and evaluation.

Consistent with the National Cohesive Wildland Fire Management Strategy, the All Lands scenario best achieved landscape scale objectives. The Rogue Basin Forest Restoration Strategy framework can be used to structure manager decision-making and has already been used to engage stakeholder and the public in conversations about management of southwestern Oregon forests. Strategy treatments should promote conditions to enable managed fire that will improve landscape resilience, climate resilience, and community safety at a reduced cost over the long-term. Continued implementation of this strategy on federal lands could encourage related work on all lands, and result in a more resilient landscape where people and nature thrive.
