Development of pooled sources

A Bower et al. 2010.

Species Specific Seed Zones:

Evidence for adaptation - Correlation between traits and source environments -

Allium acuminatum

Collect seed from many sources

Grow families in common environments

Measure many adaptive traits

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
