Landraces in situ Conservation: A Case Study in High-Mountain Home Gardens in Vall Fosca, Catalan Pyrenees, Iberian Peninsula¹

Landracesin situConservation: A Case Study in High-Mountain Home Gardens in Vall Fosca, Catalan Pyrenees, Iberian Peninsula. Interest in landrace conservation has grown over the last few decades with much research focusing on the maintenance of on-farm crop genetic diversity in the tropics. Research on landraces is less abundant in temperate climates. In this paper we assess landrace conservation status in home gardens in Vall Fosca (Catalan Pyrenees, Iberian Peninsula). We estimate the individual socio-demographic attributes associated with in situ conservation of landraces and explore the reasons for their conservation. Fieldwork was conducted March-September 2008, during which time we surveyed 60 home gardens, owned by 53 tenders from 16 villages. We recorded occurrence, abundance, uses, and management of plants cultivated in home gardens. We also inquired about the informants' reasons for conserving landraces. We found 148 different species. We identified 39 landraces corresponding to 31 species. Women, people over 65 years of age, experienced gardeners, and people who grow their home garden organically were more likely to conserve landraces than people without those characteristics. Although the informants express a strong preference for landraces, they mainly grow commercial varieties. Landraces seem to be displaced by less labor-intensive commercial varieties. © 2011 The New York Botanical Garden.
