What is Assisted Migration

Seed migration: seed sources are moved climatically or geographically within their current ranges. (Example: collecting see from droughty or flood-prone sites for propagation and out-planting at different site, but within the same seed zone)

Range expansion: seed sources or plant materials are moved to suitable areas just outside of ranges. (Example: planting California black oak north of Lane County, and still within Oregon's Willamette Valley)

Assisted species migration: species are moved far outside current ranges to prevent extinction, or to serve as a surrogate for another species in decline due to climate change (Example: planting incense cedar rom central Oregon in the Washington Cascades)
