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
