Assessment of the Ellenberg quotient as a practical tool for vertical vegetation zonation

The Ellenberg quotient (EQ) is a climate index defined as ratio of the hottest month's temperature and average annual precipitation sum. indirectly expresses relationship between vegetation, its application is related to ecological niche Fagus sp. Although was curated on grounds field research primarily German possibilities utilisation are not limited Central European region. objective this study (i) compare EQ values calculated for forest vegetation zones in Czech Republic with published data using sylvatica; (ii) new EQ-based vertical model empirical mapping. area Republic, Europe. We used from 1970–2000 National Forest Inventory, 2nd cycle (2011–2015), representing an design. Geospatial analytic methods, machine learning (boosting), verification through statistical testing were performed. results indicate higher EQ two most substantial spatial frames – Hercynicum Carpaticum regions. By comparing mapped units their climatic potential (in the EQ), match found only within presents concretisation general specific region, adds knowledge about Fagus context also points EQ's potential evaluating concept differentiation communities, as well possible prediction tool migration change.
