Seed transfer zones: levels of reference and approaches 0 M. De Vitis Seed transfer zones (STZ) represent a very useful tool to advice movement of native seeds between appropriate geographical areas. Different approaches have been used so far to define STZ, such as the ecoregional approach which involves the overlap of different layers (climate, geology, vegetation, soils, etc.) to find similar ecological conditions; the genetic approach, to study the level of population differentiation; and the adaptive approach using common-garden experiments to find the best adaptive plant population for a specific restoration goal (relevant publications: Vander Mijnsbrugge et al. 2010; Durka et al. 2016; Jørgensen et al. 2016). Even if we know that "Nature ignores borders", it may be practical to define STZ at specific geographical-administrative levels. What's the best approach to define STZ and what's the best level at which they should be defined, so as to ensure that movement of seeds for ecological restoration does not cause outbreeding in local populations?

Should agro-chemical corporation be involved in ecological restoration? 1 S. Pedrini I would suggest not to involve agro-chemicals companies in native seed coating, but instead I would suggest to a native seed producer with appropriate facilities and resources, to create an eco-friendly coating recipe to use to enhance seed germination and seedling establishment in restoration activities and to offer this service to all the native seed producers who need it.Your review, Simone, also represents an useful guideline to follow as starting point for who may want to expand the businesses and start providing coating services.
