Woody biomass was found to be the largest available LCMW biomass particularly in the model regions of Germany and Spain, whereas herbaceous LCMW biomass is only abundant in the model regions of Czech Republic. The LCMW biomass in Italian model regions is a mix of both herbaceous and woody vegetation.

Methodology

Feedstock potential data are not easily available for LCMW biomass. Some data have been collected from literature (see greenGain deliverable D4.1) on the level of EU-28 and other European projects. Available data from the BioBoost project on NUTS-3 level have been compared and validated with data from the greenGain-NUTS-3 model regions. The later data were generated by a bottom up approach described in the greenGain deliverable D5.1.

Potential and properties of landscape conservation and maintenance work (LCMW) biomass in the greenGain model regions

Woody biomass was found to be the largest available LCMW biomass particularly in the model regions of Germany and Spain, whereas herbaceous LCMW biomass is only abundant in the model regions of Czech Republic. The LCMW biomass in Italian model regions is a mix of both herbaceous and woody vegetation. The biomass potentials have been defined in terms of tons of fresh matter per annum (see the table below). The highest density of woody biomass up to 16.6 t/km2 is observed in Friesland, Germany, which is originated from the maintenance of Hedge- and tree rows on banks. The density of herbaceous biomass is highest in the model region Kněžice, Czech Republic, at 11.18 t/km2 obtained from maintenance of grass in urban space e.g. parks and recreational areas.
