“…This fact also explains the reduction of this type of forest in the study area. Arnan, Quevedo, and Rodrigo (2013) indicate that changes in fire regimes can give rise to new types of forest cover or increase the distribution range of scarce forests in a regional context. This phenomenon is indirectly evidenced in this research, and we highlight the fact that the burned areas with a high incidence of wildfires have even more difficulty in regenerating forests, especially pine forests, when those affected by fires are later occupied essentially by shrubland.…”

Wildfires are responsible for major land use and land cover (LUC) changes. These events are frequent and catastrophic in Portugal and are responsible for great damage and loss of human life. In this study, a map to assess the probability of wildfire occurrence (PWO) in mainland Portugal was created for the period 1975-2017 (first half of 2017). The PWO was obtained by the superimposition of all layers by adding all the burned areas for the total period. It was observed that the occurrences and extent of the burned areas are highly variable from year to year. The PWO map was cross-referenced with LUC geoinformation to evaluate the LUC types that were more affected by the wildfires. The results presented and the PWO maps are important for the management and planning of forest areas and for the creation of guidelines to implement preventive and reactive actions in case of wildfires.

“…The recruitment of P. halepensis is limited by too short fire recurrence intervals (Eugenio et al, 2006) and can be replaced by grasses or shrubs under recurrent fires (e.g. Arnan et al, 2013). Oliveira et al (2012) indicated that the recent fire regime observed in Portugal has already led to a substantial decrease in the area of P. pinaster.…”

Aim of study: Fire regimes are frequently dynamic and change as a function of the interactions between the three main fire drivers: fuels, ignitions and climatic conditions. We characterized the recent period and performed estimates for the future fire regime.Area of study: We have considered five pine and another four woodland types by means of the analyses of 100 reference areas in peninsular Spain.Material and Methods: The estimates of the expected alterations in fire frequency and the fire rotation period were based on models previously developed for the climatic scenarios SRES A2 and B2.Main results: The results point to the large variability in fire frequency and rotation periods between the woodland types as defined, and also among the reference areas delimited for each of them. Fire frequencies will increase for all woodland types while very relevant shortenings of the fire rotation periods are expected. For the 32 yr period analysed, rotation periods longer than 500 yr were obtained in 54% of the reference areas while this percentage would decrease to 31% in the B2 and to 29% in the A2 climatic scenario. In the most affected woodland type, P. pinaster, from a median rotation period of 83 yr it would decrease to 26 yr in the B2 and to 20 yr in the A2 climatic scenario.Research highlights: We conclude that the predicted increases in fire activity will have adverse effects on some of the main Spanish woodland types due to the expected future disruptions in the fire regime.

“…As such young stands burn, sites may be converted to persistent shrublands or resptouter dominated forests (especially if frequent burning continues), or they may require investment in planting. Such a conversion due to frequent fire has also been documented in P. halepensis forests converted to Arbutus unedo woodlands, which is a resprouter species in NE Spain (Arnan et al, 2013). Short interval fire occurrence can also cause vegetation type conversion in shrublands, especially those dominated by obligate seeders, for example in California (Lippitt et al, 2013;Meng et al, 2014).…”

“…Postfire vegetation dynamics in the Mediterranean Basin have been intensively studied (Gotzenberger et al, 2003;Kazanis and Arianoutsou, 2004;Arnan et al, 2007Arnan et al, , 2013Tavşanoğlu and Gürkan, 2014). According to the traditionally accepted approach, postfire succession in the Mediterranean Basin is primarily an autosuccessional process.…”
