“…Soil bacterial and fungal biomass is lower in fire-induced grassland areas than unaffected forest areas [4]. Post-fire tree replanting can accelerate the recovery of forest function in an ecosystem [5], thereby leading to greater recovery of the soil microbial community.…”

Abstract:Wildfire often causes tremendous changes in ecosystems, particularly in subalpine and alpine areas, which are vulnerable due to severe climate conditions such as cold temperature and strong wind. This study aimed to clarify the effect of tree re-planting on ecosystem services such as the soil microbial community after several decades. We compared the re-planted forest and grassland with the mature forest as a reference in terms of soil microbial biomass C and N (C mic and N mic ), enzyme activities, phospholipid fatty acids (PLFA) composition, and denaturing gradient gel electrophoresis (DGGE). The C mic and N mic did not differ among the grassland, re-planted forest and mature forest soil; however, ratios of C mic /C org and N mic /N tot decreased from the grassland to re-planted forest and mature forest soil. The total PLFAs and those attributed to bacteria and Gram-positive and Gram-negative bacteria did not differ between the re-planted forest and grassland soil. Principle component analysis of the PLFA content separated the grassland from re-planted forest and mature forest soil. Similarly, DGGE analysis revealed changes in both bacterial and fungal community structures with changes in vegetation. Our results suggest that the microbial community structure changes with the re-planting of trees after a fire event in this subalpine area. Recovery of the soil microbial community to the original state in a fire-damaged site in a subalpine area may require decades, even under a re-planted forest.

“…During the fire event, fire intensity, or the energy released during the fire [22], is the main factor inducing mortality in resprouter plants, as high temperatures can burn the bud bank and damage the protected aerial buds and the root system [35]. Another important hindering factor is plant size at the time of the fire.…”

“…Depending on the vector, environmental conditions, and their own physical characteristics, the seeds may be deposited at various distances from the parent individual. When it comes to primary dispersal, which normally occurs by wind or gravity, most studies concur that the vast majority of seeds are deposited within a radius of 20 to 50 m, depending on the seed type, wind conditions, and height of the parent plant and landform [35].…”

Impacts of Land Management on the Resilience of Mediterranean Dry Forests to Fire

Abstract:Wildfires have always been a part of the history of Mediterranean forests. However, forests are not always certain to regenerate after a wildfire. Whether they do depends on many factors, some of which may be influenced by land management activities. Failure to regenerate will cause a regime shift in the ecosystem, reducing the provision of ecosystem services and ultimately leading to desertification. How can we increase the resilience of Mediterranean forests to fire? Our approach to answering this question was twofold: first, we reviewed the literature to investigate chains of processes that allowed forests to regenerate (which we label Regeneration Mechanisms, or RMs); and second, we assessed the impact of selected management practices documented in the WOCAT database on these RMs. For the assessment, we evaluated the relation between the benefits and disadvantages of the land management practices on the one hand, and the hindering and supporting factors of the RMs on the other. We identified three distinct RMs that enable Mediterranean forests to recover, as well as the time frame before and after a fire in which they are at work, and factors that can hinder or support resilience. The three RMs enabling a forest to regenerate after a fire consist of regeneration (1) from a seed bank; (2) from resprouting individuals; and (3) from unburned plants that escaped the fire. Management practices were grouped into four categories: (1) fuel breaks; (2) fuel management; (3) afforestation; and (4) mulching. We assessed how and under what conditions land management modifies the ecosystem's resilience. The results show that land management influences resilience by interacting with resilience mechanisms before and after the fire, and not just by modifying the fire regime. Our analysis demonstrates a need for adaptive-i.e., context-and time-specific-management strategies.

“…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.…”
