Accelerating Loblolly Pine V i t l Forestry Varietal F t in i the th Southeastern USA Forest Landowners Association Charleston South Carolina Charleston, May 2007 Jeff Wright, ArborGen Summerville, SC Presentation Overview ¾ ArborGen Overview ¾ Background on varietal development ¾ Two reasons why varietal forestry should be accelerated in the Southeastern USA ¾ Core components of a varietal forestry program ¾ ArborGen Testing Service model for accelerating g varietal forestry y in the Southeastern USA ¾ Summary/Needs to move varietal forestry forward 2 | ¾ ArborGen is dedicated to developing trees that grow faster, on less land, thus conserving native forests in all their diversity and complexity for future generations generations. 3 | ArborGen Today ¾ ¾ ¾ ¾ ¾ ¾ Headquarters: q Summerville,, SC 100+ employees worldwide Employees in US, New Zealand, and Brazil World-wide collaborations with academia and industry Full range of commercial functions Providing leadership in varietal research and development 4 | About ArborGen ¾ Current products – Loblolly pine varietals ¾ Future products – Eucalyptus with improved pulping – Short rotation loblolly pine – Short rotation hardwoods for pulp and energy markets ¾ Conservation Collaborations – American Chestnut restoration 5 | Background B k d on Varietal Development Seedlings From Open-Pollinated Germplasm Have a Wide Range of Performance Frequ uency of Oc ccurrence Mean σ Poor = 17% Concept can apply to numerous measures of performance: ¾ Growth/Biomass ¾ Straightness ¾ Branching ¾ Disease Resistance σ Average = 66% Very Good = 12% Performance 7 | Exceptional = 5% Typical Loblolly Pine Stand 8 | Traditional Tree Improvement Has Led to New Generations of Germplasm With Improved Performance Frequenc cy of Occu urrence Generation 2.0 1.0 The same distribution of performance applies P f Performance 9 | Varietal Technology Allows ArborGen to Select the Highest g Performing g Varieties Varieties Seedlings Select varieties provide a uniform stand of the highest quality trees 10 | Improvements with Varietals ¾ Improved Consistency ¾ Improved Quality ¾ Faster Growth 11 | Two Reasons We Need to Accelerate Varietal Forestry y in the Southeastern USA: ¾ Reason #1. To Enable Forestry on High Value Land Land Cost ($/Acre) Regen. Cost –Yr-0 ($/Acre) Fert.
