Abstract:

A typical plant community, which reflects the basic community characteristics of a vegetation classification unit, can be designated as a standard unit for describing a distinct vegetation type. Providing observations of typical plant communities in the steppe is the main function of the Steppe and Desert Biodiversity Observation Network and Sino Biodiversity Observation Network (Sino BON). Methods of observing typical plant communities have been published. We set up permanent observation plots of Form. Stipa krylovii and Form. Thymus mongolicus as examples during the summer of 2017. Observation methods were applied and validated, and included stand selection and plot design, vegetation surveys, and data analysis. Based on practical observations and analysis, we demonstrated the applicability of the observation methods presented in the previously published paper “Methods of observing typical plant communities in the Steppe and Desert Biodiversity Observation Network, Sino BON”. Suggestions for the improvement of the content, methods, and indices of observation were presented with respect to problem areas. We aim to provide a case demonstrating the applicability of the standard methods for future observations.
