Abstract The two predominant oak species in Britain are Quercus robur (English or pedunculate oak) and Q. petraea (sessile oak). We sequenced the whole genomes of 386 oak trees from four British parkland sites and found over 50 million nuclear single nucleotide polymorphisms (SNPs), allowing us to identify 360 Q. robur , ten Q. petraea and 16 hybrid individuals using clustering methods. Comparing Q. robur and Q. petraea trees from Attingham Park, we found that the nuclear genomes of the two spec
