The Eurasian Bittern Botaurus stellaris suffered declines in western Europe during the 20th century, partly because of wetland reclamation. The species has been traditionally considered a reedbed specialist but recent studies identified a greater ecological plasticity than previously believed. We investigated habitat associations of a Eurasian Bittern population that has started to breed in the ricefields of northwest Italy since the early 1990s. Booming Bitterns had a higher probability of occurring in ricefields with taller rice plants, more vegetated field banks, more weeds, a larger surface and closer to remaining natural wetlands. The positive effect of field bank vegetation height on the probability that a ricefield hosted a booming Bittern declined late in the season, in contrast to the effects of weeds and ricefield area, which were stronger later in the season. A decreasing importance of vegetation on field banks to booming Bitterns may be a consequence of seasonal changes in habitat structure through the Bittern's breeding period. The degree of flooding did not affect the probability of occurrence of booming Bitterns, probably because most ricefields were homogeneously flooded during the peak breeding season (June-July). Our findings have important implications for the management of Bittern populations breeding in the ricefields of northwest Italy. We propose simple conservation actions that may favour the occurrence of booming Bitterns and help the species spread in this novel habitat.

“…Although rice fields do not provide breeding habitat for many species, there are exceptions. Bitterns and rails of conservation interest have been found to use the dense vegetation of rice fields for nesting (Longoni et al 2007;Pierluissi and King 2008) and various Charadriiformes may also benefit from breeding in rice habitats (Shuford et al 2001(Shuford et al , 2007. That said, relatively little is known about breeding success.…”

“…Similarly, harvest methods may cause widespread mortality of eggs, nestlings and perhaps adults. On the other hand, some birds apparently have the capacity to adjust their nesting behavior to match the constraints imposed by farming practices, for example by shifting the timing of nesting to match field conditions (Longoni et al 2007).…”

International audienceRice (Oryza sativa L.) is the premier food crop in the world, being a major staple food for more than half of the world’s population. The potential for a further increase in grain yield will be limited in the future, and more food will need to be produced from the same available arable land. Italy has a long history of rice cultivation, but is now facing challenges to develop new strategies to maintain competitiveness of this sector in the global market. To prepare for the inevitable reduction of both rice prices and incentives from the European Community, and market protection, growers are evaluating the potential of hybrid rice cultivation to increase yields and maintain high quality standards for milling industries. Here we reviewed the characteristics of the Italian rice sector and the first experiences of hybrid cultivation in north Italy during 2012, using them to project the potential challenges and opportunities for both breeders and rice growers. If well managed this technology can represent a solution for sustainable rice production in Italy and in the other European rice growing countries. With hybrid vigor increased yield are obtained from reduced seed rate, lower nitrogen fertilizer, lower reliance on chemical treatments to control diseases, which helps compensate for the increased seed costs. Moreover, partially in contrast with current beliefs, it is shown that it may be possible to produce rice in rather rich countries obtaining a local production
