Whitebark Pine 101
• Only north American stone pine– Cones that do not open when ripe– Wingless seed
• Seed dispersed by Nutcrackers• Caches of multiple seed results in clumpy
growth structure
• Proposed for ESA listing – in 12 month review
Clark’s Nutcracker
Clumpy growth structure
Threats
•Mountain Pine Beetle
•White Pine Blister Rust•Successional replacement•Climate change
Region 6WBPRestorationStrategy
Key Actions Prescribed
• Collect seed for gene conservation and rust resistance screening
• Assess stand conditions in priority management units • Develop plans for planting seedlings in priority management
units • Continue a rust screening program with emphasis on seed
zones in grizzly bear areas • Treat for mountain pine beetle in high risk management
units • Develop an approach for planting seedlings in designated
wilderness areas
Region 6 ex situ gene conservation plan
• 20 collection areas• Minimum of 25 trees
per collection area
• Min. 30 cones per tree– 800 seed for ex situ
gene conservation• 500 to ARS NCGP in Ft.
Collins, CO• 300 held in storage at
Dorena GRC

Accomplishments – 2009-2010
• 464 seedlots from over 50 locations for gene conservation
• 62 permanent monitoring plots at >25 different locations
• ~100 site surveys• Verbenone treatments on Fre-Win• Seed planting trials on Mt. Bachelor & Mt.
Hood
WBP Planting Projects
• 2009: “Opportunistic” planting projects on Fre-Win, Des, and GP
• 12,000 seedlings on 37 acres on Mt. Hood NF• 2010: 50 accessions added to DES preservation
arboretum• 2011: ~3000 seedlings on 5 ac. On Black Butte• Long term rust validation planting on Davis
Mtn. and 2nd replicate• 2012: – 1000-2000 seedling from resistant families
being grown for outplanting on DES
Permanent Plots
• 181 plots on Malheur NF installed mostly in 2004 some in 2009
• 200 plots on WAW NF – 100 in Eagle Cap, 100 in Elkhorns
• 78 plots on DES, WIL, MAL, COL, OKA-WEN in 2008
• 62 plots in 2009 in OR and WA• 3 on Mt. Hood plus elsewhere?
Permanent Plot Data – K. Chadwick and C. Jensen
• Blister rust infection, regeneration, WBP stand density and mortality are highly variable especially in Oregon
• Density – Avg: 350 wbp/acre (0-1442)• Mortality (WPBR & MPB) – 19% (0-77%)• WPBR – Avg: Cent OR: 25% (0-86) Malheur: 55% (35-71%) Oka-Wen: 56% (33-71%)
Perm. Plot Results
• Advanced regeneration was through out all plots, leaving us hopeful in the face of MBP
• We have two non-natives changing these stands, Balsam Woolly Adelgid in subalpine fir and Whitepine blister rust.
• Database to house region 6 data, across all land ownerships is currently being developed.
• Now have regional protocol for installation and damage codes
Genetic Diversity Testing
Molecular Markers 4 marker types 88 populations
Seedling Traits 92 Families 50 locations
Population Structure
• Isozymes – – 2 population
“groups”
• cpDNA – – 3 population
“groups”
Date of needle flush
Conclusions:Molecular markers
• Average levels of genetic diversity overall• Genetic diversity lower in Olympic
populations• Olympic populations genetically
differentiated from “main” range• Limited genetic structure in non-Olympic
populations
Conclusions:Quantitative traits
• Significant genetic variation among and within populations
• Olympic populations not differentiated based on quantitative traits
• Local adaptation driven by winter temperature
• Population differentiation greater than “selectively neutral” molecular markers
Conclusions
• Info from molecular markers and quantitative traits is complimentary but incomplete independently
• Olympic populations need special attention• Seed should not be moved into/out of
Olympics• Seed can be moved within N. Cascades and
SW Washington/Oregon, but probably not into/out of NE Washington and E. Oregon
