The Influence of Epiphytic Lichens on the Nutrient Cycling of a Blue Oak Woodland 1

  title={The Influence of Epiphytic Lichens on the Nutrient Cycling of a Blue Oak Woodland 1},
  author={Johannes M. H. Knops and Thomas H. Nash and William H Schlesinger},
We evaluated the importance of epiphytic lichens in the nutrient cycling of a blue oak (Quercus douglasii) woodland in California. Each oak tree contained an average of 3.8 kg lichen biomass, totaling 590 kg per ha. For comparison, oak leaf biomass was 958 kg per ha. We compared tree growth, volume and composition of throughfall (rainfall falling though the tree canopy), litterfall, and soil nutrients under 20 trees from which we removed the lichens to 20 control trees. The removal of lichens… CONTINUE READING
