abstract

In situ conservation of Stipa austroitalica Martinovsky ssp. austroitalica, listed as priority species in the Annex II of ‘Habitats’ Directive. This paper deals with some experimental techniques and the results yielded by the action of the population reinforcement of Stipa austroitalica Martinovsky ssp. austroitalica in the pSCI area ‘Area delle Gravine’ and, more specifically, between the gravine of Palagianello and Castellaneta (Ta – Apulia). During the field and laboratory experimentation a species-specific protocol was drawn up, including all the phases in the process, from seed collection to planting on site. Briefly, the protocol provides for the collection of anthecia between the end of May and early in June, their cleanig by awn elimination, their chilling without medium (T = 3 °C, time = 75 days) after soaking in water for 24 hours and finally their sowing in February (soil manually dug up through its superficial layers only).
