Tesis doctoral de MÁ rcia Eugenio Gosalbo
The effects of fire recurrence have been addressed in mediterranean p.Halepensis communities at a regional level in catalonia. The study design comprised 28 study sites distributed over the pinus halepensis-dominated surface of the region. Every study site was conformed by two areas, which were very similar in terms of climatic and geomorphic characteristics, and differed mainly in the number of fire events that had suffered along two decades. One-burnt areas had been burnt only in 1994. Twice-burnt areas had been burnt firstly between 1978 and 1993, and again in 1994. Survey was synchronically conducted in both types of areas 8 to 11 years after fire. Fire recurrence effects were addressed on: structural features, floristic composition, soil organic horizons, p.Halepensis populations, and plant growth. Fire repetition at fire intervals shorter than 17 years has been observed to result in a loss of resilience of mediterranean p.Halepensis communities, which shifted to shorter, more open, less productive, shrub-dominated communities were p.Halepensis was present at low densities, or even absent.
