WHAT THE EVIDENCE SAYS
A forestry forum synthesizes emerging genomic tools for climate adaptation, including combining provenance and genetic information, using climate-gradient genomics to identify locally adapted variants, assessing stress-related gene expression, and applying epigenetic evidence to population vulnerability and seed sourcing. California tree examples illustrate how these approaches could complement conventional seed zones.
WHY IT MATTERS / OUR READ
Assisted migration and seed transfer are increasingly becoming information problems as well as nursery problems. Genomics may help distinguish populations that look similar now but have different adaptive potential under future climates.
CAVEATS / UNCERTAINTY
Several proposed genomic and epigenetic applications remain emerging rather than routine operational tools. Genomic signals should complement common-garden trials, provenance history, local ecology and genetic-diversity safeguards rather than replace them.
