Objectives

The key objectives of NNEXT can be summarized as follows:

1. Collect, process and harmonise existing information on non-native tree species distribution in Europe. This step includes an analysis of the historic reason in promoting species, maps, and existing data. Based on this initial step we may select certain key tree species for an in depth analysis across Europe.

2. Assess introduction and distribution pathways (including geographic origin) of non-native species. Defining the role of natural regeneration in the integration and persistence of non-native species in native forest ecosystems.

3. Collect and analyse silvicultural management practices in Europe. This will include the assessment of the growth performance, the multifunctional role of given non-native tree species as well as a review of existing management models for non-native tree species. The management of these species for biomass production and for high quality wood materials as well as the profitability and performance of non-native tree sales at the wood markets will be addressed, as well as the possibilities for co-management of mixtures of native and non-native species.

4. Assess the ecological risks for native tree species. In particular we are interested in related changes on biodiversity and nature conservation issues associated with changes in the competitive situation of native tree species. New pests and pathogens which might be introduced and effect European forest ecosystems will also be addressed. For selected non-native tree species, their potential for spreading across Europe will be assessed. This assessment will be based on climate and soil data maps. These data sources will (i) provide information about the opportunities (climate change adaptation/mitigation, biomass production etc.) for promoting non-native tree species (ii) assess the risks (loss in biodiversity and sustainability, loss in ecosystem stability and thus an increase in ecosystem vulnerability) for the established native forest ecosystems.
