Dataset Abstract

The main objectives of this task are to quantify the decomposition of a mixture of litter with the plot-specific diversity, and to relate this information to tree diversity and environmental gradients across sites.

Dataset Design

See sampling protocol: “Litter decomposition” for details

Spatial Extent

Italy - Toscany

Temporal Extent

This file contains the mass loss data for litter mixtures placed to decompose in June 2012 and collected in July 2013
