European larch (Larix decidua Mill.) is an important tree species commonly used in managed forests of central Europe. However, its genetic structure, post-glacial range dynamics, and consequent nativity status are poorly understood. Here we provide the first study focusing on the genetic structure of in situ larch populations in the north-eastern Czech Republic using molecular genetics. Most of the studied area is traditionally considered to be a part of the autochthonous native range of the Jeseníky lineage of larch and some of the included populations are protected as belonging to this type. We confirm a common presence of the Jeseníky type and its close evolutionary relation with larch populations from both the Carpathians and Poland. However, we also found important levels of admixture of genetic material from the Alps in all of the analyzed populations. The highest amount of Alpine admixture was found in the populations of intensively managed forests, the proportion of non-native material in the protected areas was relatively lower but still significant. Our results show the importance of populationgenetic research for practical conservation of local populations and lineages even for common species.
