As they grapple with
climate change, forest-
ers in British Columbia
and their colleagues
have planted 152,376
seedlings from 15 tree
species at 48 sites
between Northern
California and the
southern Yukon. This
massive enterprise,
known as the Assisted
Migration Adaptation
Trial, aims to ensure
that species and
seed sources selected
for planting will be
well suited to climate
conditions they may
experience throughout
their lifetimes.
