Abstract: Salvage logging is a usual emergency action carried out after in burned areas, but ecological effects remains unclear. Based on the projections of the Intergovernmental Panel on Climate Change, droughts in the Mediterranean Basin will increase which will change fire regimes. In this new scenario, forest management should be reviewed and adaptation should be implemented. Therefore, we carried out a study to check effects of salvage logging and summer drought in burned Aleppo pine forests.
In summer 2009, a mid-high severity fire burned 968 ha of Aleppo pine (Pinus halepensis Mill.) forest in south-eastern Spain. Six months after the fire event, the Public Administration responsible of Forest Management carried out salvage logging. In spring 2010, we randomly established three 25-m linear transects in both study areas. Pine seedlings intercepting lines were counted and their total height recorded. During summer 2010, we set five square plots (2m x 2m) in untreated area and twenty square paired plots (2m x 2m) in logged area to follow recruitment and development of selected species. We induced drought by using rain-exclusion shelters covering 20% of the surface to intercept the same percentage of natural water supply by rain. We recorded soil water availability and the water stress in the plants, the predawn leaf water potential and abundance and coverage. We selected the resprouter Esparto grass and two obligate seeders, Rockrose and Rosemary to characterize the morphological development and physiological dynamics. Height and coverage were recorded, in addition to transpiration rate, net photosynthetic rate, stomatal conductance and water use efficiency by using a portable gas exchange system. Seedling growth in control plots was significantly higher for the three species, being the coverage significantly higher for both seeder species. Regarding to the status of the plants, the esparto grass showed the lowest mean leaf water potential value in both treatments. After the drought period, the leaf water potential values were higher in the control area although not significantly. The net photosynthesis revealed significant differences depending on the species and the treatment, showing higher ratios for both seeder species but not affected by drought. We found no significant differences on survival. The water status of the studied species varied with the interception of 20% of precipitation although was significant just for esparto grass. However, lower transpiration and water use efficiency were found in the control area which induced the stimulation of the total height and cover, especially for seeders, rosemary and rockrose individuals. It was confirmed that climate change in the Mediterranean area influences productivity and development of adapted communities in the short term. Such a record could imply a failure on the survival or regeneration in the medium and long-term, mainly after disturbances such as severe droughts or wildfires.

Title: Tools for Assessing Impacts of Climate Variability and Change on Forest Fire
Authors: Hety Herawati, José Ramón González-Olabarria, Herry Purnomo, Rubeta Andriani, Arief Wijaya, Christopher Martius
Abstract: Climate change can alter factors influencing the occurrence of ignitions, and fuel flammability and availability. There have been increasing concerns about the potential impacts of climate variability and change on fire regimes. This review paper aims for identifying tools and methods for gathering information on the impacts of climate variability and change on forest fire. Some tools including remote sensing, vegetation simulation models, fire danger rating systems, empirical models, integrated fire-vegetation models, and fire models are available for assessing the impacts of climate variability and change on forest fire. Each tool has its characteristics, methods to follow, and strengths and weaknesses.
