Community matrix of the Mt. Mongón

Description

A community matrix with species as columns and sites as rows. The rownames correspond to the id which can be also found in [random_points]. Please note that in fact 100 sites have been visited but in 16 of them no species could be found (see again [random_points]). The data is used in the "Ecology" chapter in Geocomputation with R. See https://geocompr.robinlovelace.net/eco.html for details.

Format

A dataframe with 100 sites (rows) and 69 species (columns). Species presence is given in percentage points (between 0-100 site). Due to overlapping cover between individual plants, the total cover per site can be >100%.
