Key Aspects of Hardwood Supply
• Alder component has declined on the landscape and as % of harvest .
• Alder “comes along” with softwood harvest –ups and downs of regional harvest trends.
• Retention and management for alder in younger stands has increased.

Greater attention to management of hardwoods will be needed to sustain benefits from hardwoods.
•Abundant alder is a legacy of past practices – current practices generally reduce the alder component.

Knowledge of and management for alder is increasing.
![Page 12: Hardwood Resource Ownership, Location, and Supply Issues Glenn Ahrens Oregon State University Extension Forester](https://reader036.vdocument.in/reader036/viewer/2022062511/55140a19550346e2488b4d1c/html5/thumbnails/12.jpg)
Foresters and landowners often leave alder in young stands when it appears to be the “best tree”.

The hardwood component on non-industrial private woodlands is increasingly important …

The future depends on hardwood management
• Current abundance – Legacy of past management
• Future abundance– Management favoring conifer – Management for hardwood?

Hardwood Timber Resources
— Continuing management favoring conifers on major private and public lands.
— Non-forest development, particularly on lowlands— Oregon 0.2% per year, 10x worse in Washington?
┼ Increasing value of alder – major industry and employment.
┼ Increasing management for alder - both economic and ecological goals.

Hardwood Timber Resources
• Non-industrial forests have about half the hardwood , continue to regenerate hardwood, and provide growing share of supply.
• Foresters are increasing alder management.• State Forests aim to provide consistent timber
supply including red alder. • Social & Political Climate - Movement towards
balance between economic and environmental.

Summary - Hardwood Supply Situation
• Recent harvest volume of alder (2007-2009) is about half what it was 15 years ago.
• Alder component declining on the landscape and as % of harvest – decline leveling off?.
• Alder comes along with softwood harvest -regional harvest trend drives alder supply.
• Available landbase and market factors drive forest harvest – worst is over?
• Alder retention and management – increasing.

Outlook for Hardwood Timber Priorities for action
• Increase public understanding and acceptance of forest management - maintain “license to practice forestry”
• Keep forest lands in forest – prevent conversion to non-forest
• Increase professional knowledge and skills in Hardwood Forest Management
• Demonstrate success and transfer the technology
