Table 2. Parameter values for traits of native plants.

Note that maximum age is aligned for all species. Reproduction and dispersal values are not considered for native species as we were not interested in the fate of native species in this approach. Parameter values were either directly retrieved or approximated (∗) from the available literature. The composition of the native community in uneven mixtures is based on seed bank values. Initial seed density for F. rubra (∗∗) has been approximated from vegetation cover (30%) as retrieved from Edwards & Crawley (1999), assuming that all seeds germinate and build the entire native community.
