“…The majority of studies involving lichen biomass at tree-and stand-level have been conducted in North American temperate/boreal hardwoods [9][10][11][12] and coniferous forests [3,[13][14][15][16][17]. Epiphytic lichens constitute a small proportion of the total forest biomass in these forests, and the biomass distribution is controlled by forest (e.g., stand age and community structure) and host (e.g., species, diameter, and height) characteristics [11,15,18,19].…”

Epiphytic lichens are an important component in subtropical forests and contribute greatly to forest biodiversity and biomass. However, information on epiphytic lichens still remains scarce in forest conservation owing to the difficulty of accessing all canopy layers for direct observation. Here, epiphytic lichens were quantified on 73 whole trees in five forest types in Southwest China to clarify the vertical stratification of their biomass in subtropical forests. Lichen biomass was significantly influenced by forest type and host attributes, varying from 187.11 to 8.55 g•tree −1 among forest types and from 289.81 to <0.01 g•tree −1 among tree species. The vertical stratification of lichen biomass was also determined by forest type, which peaked at the top in primary Lithocarpus forest and middle-aged oak secondary forest and in the middle upper heights in other forests. Overall, the proportion of lichen biomass accounted for 73.17-100.00% of total lichen biomass on branches and 0.00-26.83% on trunks in five forests, and 64.53-100.00% and 0.00-35.47% on eight host species. Seven functional groups showed marked and various responses to tree height between and among forest types. This information improves our understanding of the distribution of epiphytic lichens in forest ecosystems and the promotion of forest management in subtropical China.

“…Numerous studies in temperate and boreal as well as in desert areas have been carried out to quantify the contribution of cyanolichens to nitrogen fixation. Lichen species of the genera Lobaria, Collema, Leptogium, Peltigera and Sticta occurring in forests of Northern European and North American, for instance, exhibited annual N-fixation rates of 2-11 kg ha −1 (Becker et al 1977). In deserts and semi-desert regions of the World, lichens are particularly frequent in biological soil crusts, (BSC) where their coverage may approach 100 % of the plant interspaces.…”
