The boreal forest, with large tracts of unmanaged forests and low human impacts, is critical for the stability of global ecosystems. However, the boreal regions are subject to extensive ecosystem shifting, thinning and even loss under the climate changes and human activities, especially with the increasing of global warming. How to cope with the trend is extremely urgent. To illustrate responds of future populations of forest trees to climate change, it is essential to uncover past and present signatures of molecular adaptation in their genomes. Ecological epigenetics, as an interdisciplinary mainly answering how species, especially perennial, adapt to environmental changes epigenetically, is an important approach to detect the epigenetic mechanisms of boreal forest plants adapting to climate changes. Here, we will report the recent results about DNA methylation involved in environmental adaptation of birch, the pioneered trees of boreal forest.
