Responding to EO 14072 to Classify and Inventory Mature and Old-Growth Forests
Speaker(s): Marin Palmer, United States Forest Service
Description: Executive Order 14072 instructed the Bureau of Land Management and Forest Service to define and inventory old-growth and mature forest for lands managed by the agencies. The old-growth and mature definition, identification criteria, and resulting inventory reported met this direction and identify where these forests currently occur.

Wicked Problems and Sticky Wickets: Defining and Inventorying Mature and Old-Growth Forests
Speaker(s): Andrew Gray, USFS - Research and Development
Description: Mature and old-growth forests are valued for many ecosystem services but defining such forests is complex and involves values, science, and management perspectives and may require multiple disciplines. Identification will likely require ground and remotely sensed measurements, local criteria, and use of social and traditional knowledge.

Estimating Old-Growth Forests Using Regional Guidance
Speaker(s): Kristen Pelz, United States Forest Service, Forest Inventory and Analysis
Description: The USFS and BLM chose to apply existing structural definitions for old-growth in each region and for each forest type in response to EO 14072. Retaining existing definitions allows for consistency with publicly vetted land management planning. These definitions were then applied to the national FIA database for public lands.

Classifying Mature Federal Forests in the United States: The Forest Inventory Growth Stage System
Speaker(s): Andrew Gray, USFS - Research and Development and Christopher Woodall, USFS - Research and Development
Description: We developed an inverse modeling approach to define mature forests based on long-established and recognized old-growth structural attributes. This approach uses a variety of components that can be refined across future versions of the model using emerging technology, refined relative length of growth stages, and incorporation of other social/cultural values.

Defining and Inventorying Mature and Old-Growth Forests based on Carbon Accumulation
Speaker(s): Gregory Aplet, The Wilderness Society
Description: As opposed to the more common structural definition of old growth, we employed FIA plot data in a functional approach based on objectively identified points along modeled carbon accumulation curves of developing stands to classify and inventory old growth and mature forests in all forest type-groups nationwide.

Summary and Next Steps in the Stewardship of Mature and Old-Growth Forests
Speaker(s): Jamie Barbour, United States Forest Service
Description: The United States Forest Service and Bureau of Land Management have completed their first ever inventory of mature and old-growth forests after considering input from Tribes, the public, stakeholders, partners, and employees. Ongoing work includes risk and threat assessments as outlined by other provisions of the Executive Order.
