Variation in moss biomass as an effect of the use and management of sites in a forest of Abies religiosa (Kunth) Cham. & Schltdl. in Mexico. Rev.

Introduction:
Mosses are pioneer organisms known for their high-water storage capacity and biomass. Consequently, they play a significant structural and functional role in terrestrial ecosystems.
Objective:
The aim of the present study was to analyze whether there is variation in moss biomass and water storage capacity among moss species because of site use and management in a fir forest at Parque Nacional El Chico, Hidalgo, México
Materials and methods:
A total of ten sites were selected, distributed across an altitudinal range of 2 781 to 2 981 m: three in the core zone of the park, three in the buffer zone (tourism without moss extraction), and four in the zone with moss extraction. Plots and subplots were established at each site to estimate the biomass and water storage capacity (WSC) of moss species. Furthermore, the coverage of the herbaceous and shrub strata at the sites was determined.
Results and discussion:
Thuidium delicatulum (Hedw.) Schimp. var. delicatulum predominated in biomass across all sites. The highest moss biomass (0.140 g∙cm-2) was found in an extraction site (Esquillero), while the highest Water Storage Capacity (WSC) (0.254 g∙cm-2) was estimated in ecotourism-oriented sites (La Orozca). In sites with moss extraction, coverage of the herbaceous and shrub strata was minimal, and moss biomass increased.
Conclusions:
Use (conservation, ecotourism) and management (extraction) of the forest affects the biomass and WSC values of mosses and the percentage of understory cover (herbaceous and shrubs).
