HoliSoils harmonises and maps soil data from multiple sources. These harmonised products are indispensable for Europe-wide GHG inventories and for the project’s experimental and modelling work in Europe’s main bioclimatic regions and soil types.

Field experiments at HoliSoils test sites will investigate the effects of soil and forest management (including thinning regimes, tree species composition, fertilisation, rewetting) and natural disturbances (forest fires, windthrow, droughts) on soil processes, resilience and climate change mitigation potential. Measurements of soil physico-chemical properties and biodiversity will be complemented by monitoring soil processes such as GHG fluxes and nutrient cycling.

Ground vegetation
Presence of Acer campestre and Fraxinus excelsior in the tree layer, with understory composed of different species (Viburnum lantana, arbutus unedo, Rhamnus alaternus, Ligustrum vulgaris or Corylus avellana, among others). Climbing plants such as hedera helix, Lonicera periclymenun or Smilax aspera are also well represented. The herbaceous layer is represented by many nemoral species.
