Database manager(s): Alvaro G. Gutierrez (bosqueciencia@gmail.com)
Owner: Alvaro G. Gutiérrez
Scope: Stand data of regular plots
Abstract: The database contains stand structure variables (number of trees, basal area and dominant height) both at species and plot level. Data coverage includes Chile and Argentina temperate forests. Data were collected from scientific articles and research projects by the author. The database includes auxiliary information from each site, such as soil variables, forest disturbances and geographic coordinates of the plots.
