Nevill, P. G., Tomlinson, S., Elliott, C. P., Espeland, E. K., Dixon, K. W. and Merritt, D. J. (2016), Seed production areas for the global restoration challenge. Ecol Evol, 6: 7490–7497. doi:10.1002/ece3.2455

Wild-collected seed can no longer meet global demand in restoration. Dedicated Seed Production Areas (SPA) for restoration are needed and these require application of ecological, economic, and population-genetic science. SPA design and construction must embrace the ecological sustainability principles of restoration.
