SUMMARY With the impact of climate change and anthropogenic activities, underlying threats facing populations with different evolutionary histories distributions, associated conservation strategies necessary to ensure their survival, may vary within a species. This is particularly true for marginal and/or those showing admixture. Here, we re‐sequence genomes 102 individuals from 21 locations Rhododendron vialii , threatened species distributed in subtropical forests southwestern China that has suffered habitat fragmentation due deforestation. Population structure results revealed R . can be divided into five genetic lineages using neutral single‐nucleotide polymorphisms (SNPs), whereas selected SNPs divide six lineages. Guigu (GG) population, which identified as admixed SNPs, but assigned distinct cluster non‐neutral loci. experienced multiple bottlenecks, demographic have been suggested among populations. Ecological niche modeling combined genomic offset analysis suggests population (Northeast, NE) harboring highest diversity likely risk maladaptation future. The therefore needs urgent ex situ areas where influence future predicted well buffered. Alternatively, GG potential local adaptation, will need conservation. Puer carries heaviest load, rescue. Our findings highlight how genomics, analysis, ecological integrated inform targeted
