1. Pacific Northwest Forest Tree Gene Conservation Cooperative
2. Mission:
To ensure that the adaptation and evolutionary potential of important regional tree species are maintained
3. A Brief History of PNWFTGCG Prior to 1995
Gene conservation a topic at several WFGA meetings
Periodic meetings of the “Gene Team”
1995 to 1999
Organization established in 1995 with 10 contributing members
Produced a draft “framework document”
1997: Workshop to reach a consensus on approach
Focus on eight commercial conifer species
Two phase approach:
(1) information gathering & (2) implementation
Hire a two-year post-doc to conduct phase 1
Additional funds solicited, six new members
4. Two phase approach to gene conservation Phase 1: Survey existing genetic resources. Identify areas where genetic resources are well-protected and where additional conservation measures are warranted
Phase 2: Identify tactical and management options for addressing gaps and long-term monitoring of genetic resources
5. Contributing members

15. In situ gene conservation conclusions For five of the eight species examined, genetic resources are well-protected in situ throughout western Oregon and Washington
For ponderosa pine, gene conservation activities are in place for the areas least well protected
For noble fir and western white pine, additional conservation may be warranted for a few areas
16. Ex situ gene conservation: Survey of existing resources Seed stores
Progeny tests
Provenance tests

17. Douglas-fir 1st generation progeny tests Multiple breeding pouplationss; Namkoong has argued is on e of the most effective ways to conserve genetic diversity.
Throughout western Oregon and Washington, forestland management organizations are engaged in tree improvement programs for coastal Douglas fir that were founded on the “progressive” system first introduced by Dr. Roy Silen in 1966 (Silen 1966). In this system, commercial seed is initially collected directly from parent trees.
These breeding zones span most of the range of coastal Douglas-fir (Figures 1 and 2); the few areas that are not included are well represented in in situ reserves
The partitioning of selections into small breeding zones stratifies the genetic resources of the region into local groups that are rarely moved out of their geographic region of origin. Moreover, it essentially creates multiple breeding populations, which notably Namkoong (1976) has argued is one of the most effective ways to conserve genetic diversity.
This is especially true since roughly 80% of the selections, at least those included in the NWTIC programs, were not intensively chosen “plus trees”. Rather a “roadside selection” approach was used that emphasizes obtaining a good sample of the better phenotypes (i.e., healthy, vigorous, and well-formed)

18. Douglas-fir 2nd generation NWTIC tests
19. Douglas-fir ex situ genetic resources First generation progeny tests represent in excellent gene resource population
This population is valuable if breeders decide to screen for new traits, reassess traits of current interest in older trees, or move trees in response to global climate change
We advocate maintaining first generation progeny tests

22. Ex situ gene conservation conclusions The extent and importance of ex situ genetic resources varies widely among species.
Species specific issues drive the collection of ex situ genetic resources
First generation progeny tests represent a valuable ex situ genetic resource.
