In this study we have analyzed the post-fire recovery ability of 15 woody species that occur in relatively low abundance in dry and sub humid Mediterranean areas in NE of Spain. The main goals have been i to determine experimentally the post-fire resprouting ability of these species and ii to compare the abundance of these species in areas affected by wildland fires and in unburned areas. We have observed a high resprouting ability after prescribed burning of most species except for Juniperus communis and J. phoenicea which showed a null resprouting. As the species with high resprouting ability showed similar presence in burned and unburned areas we can conclude that wildfires are not a factor that constrains the presence of these species in Mediterranean woodlands. However we found a reduction in the abundance of J. communis and J. phoenicea at the regional level after wildland fires. distribution area prescribed burning resprouting woody species Juniperus Résumé - Capacité à rejeter de souche de 15 espèces d arbres et d arbustes secondaires de la region méditerranéenne après incendie.
