Seedling and species recruitment of sown plant species

Seedling and species recruitment data for exotic ("EXO") and native ("NAT") sown species were recorded in the field on 0.5 x 0.5 square meter subplots in seed addition and control subplots (separate column "Control") on 18 experimental sites in two regions (8 Central California ("CA"), 10 Central Germany ("GE")). Data were recorded in 2012 (census 1 and 2) and 2013 (census 3). Subplots were either located in rodent exclosure (Rod), gastropod exclosure (Gas) or control plots (Con). The number of added seeds per species ranged from 50 to 175 (column "Number"), depending on the seed size. The number of sown species ranged from 17 (California) to 20 (Germany). Acronyms for the species can be derived by taking the first 3 letters of the genus and species names (see Table A 4).
