Policies to Encourage Early Successional Ecosystems on Forest Sites in Oregon:

What Might We Do?

K. Norman JohnsonDebora L. Johnson

Early successional ecosystems on forest sites are relatively rare

In Oregon’s Coast Range:

- currently less than 3% of forest

- projected to be less than 2% of forest in future

- most will be provided by State forests

Focus of my talk

Policy and management challenges of increasing early sucessional ecosystems on

federal and private forests

Policy Changes on Federal lands

Goal: create more diverse early seral ecosystems

Three stage approach:

1) Leave burned areas alone

2) Demonstrate regeneration harvest strategies that create diverse early seral

3) Emulate large-scale disturbance on the national forests through regeneration harvest of plantations

Baker,  et al. 2006 Implementation monitoring: Summary of NWPF regional interagency monitoring results

2. Demonstrate silvicultural strategies that create diverse early seral

• Where and how would we harvest?

• What would be the effect on timber yield?

• Should we plant at all?

Yields Compared to High Intensity Management

• Regeneration harvest: 70-80%– Reduction from legacy trees

• Long-term yield = 30-60%??– Reduction from legacy trees and

nurturing of shrub stage

Regeneration harvest = clearcutting

Coast Range Harvest Rates

“One thing is certain: there must be a decided change

in our attitude toward our timber resources… The forest

is a renewable resource. In the interest of the nation

and of the state, Oregon’s forests should be renewed:

and, by all means, there should be as little delay as

possible in making a beginning.”

George W. Peavy, 1929

The purpose of the reforestation rules is to ensure that forest tree cover is maintained or re-established after harvest.

Tree Species Suitable for Reforestation

1. The species must be ecologically suited to the planting site;

2. The species must be capable of producing logs, fiber, or other wood products;

Minimum Tree Stocking StandardsOregon Forest Practices Act

In general, a tree will be considered free to grow if:

….

It is taller than, and out-competing, any grass, shrubs, or other trees growing within a 10-foot radius from the tree.

Where are we now?

• Threat of timber famine greatly diminished

• Problems with successful regeneration largely solved

• A forest industry that views wood as a renewable resource

New Regulations?

Possible policy changes---- Private lands

Challenge: create more diverse early seral forest while reducing the regulatory burden/allowing choice

Ideas:

• Remove free-to-grow requirement

• Remove regeneration requirement in its entirety

• Allow substitution of an invasives eradication plan, enhanced wildlife tree plan, or logging debris retention plan

Allow substitution of an invasives eradication plan

Potential slogans

• Forced regeneration = tyranny

• Protect the freedom of shrubs and forbs

• No death panels for little plants
