Needs assessment/ species selection
Which, from where and how much?
For agricultural seed production
Multiple species – multiple issues
Where is the info?

Collectors: Project Cooperators Seeds of success Agency personnel Volunteers, students
Germplasm conservation Initial increase
Based on: Minimum winter temperature Aridity index Omernik ecoregions overlay Development of pooled sources A Bower et al. 2010.
Species Specific Seed Zones:
Evidence for adaptation - Correlation between traits and source environments -
Collect seed from many sources Grow families in common environments Measure many adaptive traits Seed zone map Oregon Idaho Nevada

Future Priorities: The Vision
Species selection priorities: manager feedback, production capacity Increased focus on genetics: more species specific seed zones, rapid testing of provisional seed zones, climate change,
enclosure / common garden network!!!
Focus on seed increase: work to set up a better / more rapid way to increase seed stock for foundation seed
