Dataset Abstract

The main objectives of this task are to quantify litterfall production and its composition and chemical content over time, and to relate this information to tree diversity and environmental gradients across sites.
By relating litter production data with data on aboveground stand-level productivity and root biomass production, this task will also test the assumption that litter production is a good proxy for productivity.Contains dry weight data of different litter fractions sorted by: leaf litter per plot per species (devided in target species for the respective plot and non-targed species), woody material, reproductive material, animals and undefinable rest.

Dataset Design

See sampling protocol: “Litter production and element fluxes” and deliverable 3.5 "Litter fluxes" for details.

Spatial Extent

Italy

Temporal Extent

November 2012 – October 2013

Quercus cerris, Quercus ilex, Quercus petraea, Castanea sativa, Ostrya carpinifolia

Measurement Circumstances

Due to snow fall or other unfavourable conditions, litter could not be collected on a two-weekly basis as described in the protocol.
