“…For example, LULC changes reflected in a hypothetically lowered fire hazard, because of biomass removal, may in fact increase fire risk. These include a more intensive use of pastures associated with an increasing use of fire for pasture renewal (Arianoutsou, 1998;Bajocco and Ricotta, 2008;Martinez et al, 2009;Mouillot et al, 2003), or an increased wildland-urban interface due to urban sprawl (e.g. Arianoutsou, 2001;Curt and Delcros, 2010;Martinez et al 2009;RomeroCalcerrada et al 2010;Wittenberg and Malkinson, 2009;Vasconcelos et al 2001;Vazquez et al 2002).…”

“…The same was shown by Arianoutsou et al (2002) for Pinus halepensis forests in central Greece. The reason behind this shift is related to the characteristics of the reproductive biology of these pines (Arianoutsou 1998). Pinus halepensis individuals reach their full reproductive capacity when 15-20 years old by having a canopy seed bank in their serotinous cones.…”

Every year approx. half a million hectares of land are burned by wildfires in southern Europe, causing large ecological and socio-economic impacts. Climate and land use changes in the last decades have increased fire risk and danger. In this paper we review the available scientific knowledge on the relationships between landscape and wildfires in the Mediterranean region, with a focus on its application for defining landscape management guidelines and policies that could be adopted in order to promote landscapes with lower fire hazard. The main findings are that (1) socio-economic drivers have favoured land cover changes contributing to increasing fire hazard in the last decades, (2) large wildfires are becoming more frequent, (3) increased fire frequency is promoting homogeneous landscapes covered by fire-prone shrublands; (4) landscape planning to reduce fuel loads may be successful only if fire weather conditions are not extreme. The challenges to address these problems and the policy and landscape management responses that should be adopted are discussed, along with the major knowledge gaps.

“…the recovery of Mediterranean vegetation is a process of secondary autosuccession (Trabaud 1994). Plants of the Mediterranean vegetation overcome the effects of fire, as well as of summer drought, through a variety of different survival strategies (Trabaud 1994;Arianoutsou 1998;Trabaud and Prodon 2002). Seed germination and seedling establishment of annuals as well as of perennial species is generally promoted by fire when it occurs at the appropriate time of the year (i.e.…”

Short-term invasibility patterns in burnt and unburnt experimental Mediterranean grassland communities of varying diversities

This paper reports the findings of a short-term natural invasibility field study in constructed Mediterranean herbaceous communities of varying diversities, under a fire treatment. Three components of invasibility, i.e. species richness, density and biomass of invaders, have been monitored in burnt and unburnt experimental plots with resident diversity ranging from monocultures to 18-species mixtures. In general, species richness, density and biomass of invaders decreased significantly with the increase of resident species richness. Furthermore, the density and biomass of invading species were significantly influenced by the species composition of resident communities. Although aboveground biomass, leaf area index, canopy height and percent bare ground of the resident communities explained a significant part of the variation in the success of invading species, these covariates did not fully explain the effects of resident species richness. Fire mainly influenced invasibility via soil nutrient levels. The effect of fire on observed invasibility patterns seems to be less important than the effects of resident species richness. Our results demonstrate the importance of species richness and composition in controlling the initial stages of plant invasions in Mediterranean grasslands but that there was a lack of interaction with the effects of fire disturbance.

“…Kavgacı et al (2010) generalized that Fabaceae tended to reach their highest species richness in P. brutia forests in the eastern Mediterranean at about 3 years after fire. Many studies have documented this pattern in early postfire succession in the eastern Mediterranean (Kazanis and Arianoutsou, 1996;Arianoutsou, 1998;Arianoutsou and Ne' eman, 2000;Türkmen and Duzenli, 2005). Overall our results support this generalization.…”
