Resumen:	Interest in landraces conservation has grown in the last decades with research on the topic focusing on in situ conservation of agrobiodiversity in the tropics. Researchers agree that home gardens play a key role in the maintenance of in situ agrobiodiversity, but few studies have analyzed how farmers actually maintain agrobiodiversity in home gardens and what mechanisms they use to avoid genetic erosion. We evaluate the functioning of a network of seed exchange and explore its contribution to agrobiodiversity conservation. We focus on the exchange of seeds and seedlings among 55 home garden keepers who grow a total of 62 home gardens in Vall Fosca (Catalan Pyrenees). Fieldwork included visits to gardens and surveys to register the frequency and management of local landraces. We also asked about the farmers' network of seed exchange. We identified 20 local landraces belonging to 17 species. People who were mentioned more often in the network of seed exchange (highest indegree) and who had a higher level of intermediation among other people in their personal network (highest egobetweenness) conserved more local landraces and had more local landrace knowledge than people who were less central in the network. Our findings suggest that local landrace conservation is strongly associated with individual position in the network of seed exchange.
