The bark is the outermost defense of trees against microbial attack, largely due to toxicity of extractive compounds. Here, Ristinmaa et al. study microbial community dynamics and chemical changes during degradation of spruce bark over six months, showing that the microbial degradation of extractive compounds, such as resin acids, has a major role in shaping the microbial community.
