Rodent populations respond quickly to changes in habitat structure and composition resulting from disturbances such as wildfires. Rodents may recolonise burnt areas from individuals that survived the wildfire in ‘internal refuges’ orfrom the surrounding unburnt area (i.e. external colonisation). With the aim of assessing the relative role of both h...

Following wildfires, salvage logging is applied for silvicultural, safety or even aesthetic reasons. Such operations impact on biological legacies, impair natural vegetation recovery and may affect several animal species that depend on vegetation structure and specific plant resources. Rodents, such as wood and Algerian mice, use vegetation cover a...

The selection of the many biological indicators described in scientific literature is rarely based on systematic or clear-cut processes, and often takes into account only a single or very few taxa, or even disregards the complex interactions that exist between the components of biodiversity. In certain cases, the particular context of a site–for ex...

The loss of open habitats in Europe has led to severe declines in birds associated with these habitats. However, certain ecological disturbances reverse the trend towards afforestation and create appropriate conditions for open-habitat species. Yet, open-habitat bird occupancy dynamics after disturbance depend on a complex combination of as-yet poo...

An average of 213,000 ha of European forest is affected by fire every year, with 90% of this area corresponding to Mediterranean countries. The timber of the burned forests is usually harvested by clearcutting over large areas to be used mainly as bioenergy. Recent scientific evidence has shown the strong impact that these "salvage logging" practic...

Wildfires play a determining role in the composition and structure of many plant and animal communities. On the other hand, climate change is considered to be a major driver of current and future fire regime changes. Despite increases in drought in many areas of the world, the effects of aridity on post-fire colonization by animals have been rarely...

Effects of the distance from the burnt area perimeter on the recovery of rodent populations and on seed removal by rodents after wildfire
Thesis
Full-text available
Wildfires are natural disturbances that affect landscape structure and biodiversity. Particular climates have favoured high frequency of wildfires, a selective factor affecting morphology, physiology and life cycles of plants and animals. Fire has also played a key role influencing landscape structure and biotic communities in the Mediterranean Bas...

Wildfires are a main ecological disturbance that affects ecosystems around the world. Only in Europe, 213,000 ha of woodlands have burnt every year since 1961, 90% of this area being in Mediterranean countries. Burnt forests are being logged more extensively due to changes in forestry practices in these countries. Log harvesting, leaving low value timber remaining on the ground, has recently shifted towards the use of heavy machinery, harvesting whole trees for bioenergy. The effects of this “salvage” logging after wildfire are of concern to the scientific community. Logging management, soil compaction and ecosystem regeneration are main topics of study and discussion. In 2016, our research team published a “Handbook of good management practices in burnt Mediterranean forests” (available at: http://anifog.wixsite.com/anifog/blank). The recommended practices compiled in this publication are aimed to be an economically and environmentally sustainable alternative to the conventional practices of harvesting of burnt forests. The aims of the current project are to experimentally test alternative management practices recommended in the handbook. We are currently measuring the effects of non-intervention (NI), conventional (CL) and sustainable logging (SL) through multiple selected indicators in a mixed pine-oak forest burnt in 2016. The indicators are related to soil fertility and erosion, woody biomass, plant regeneration, invertebrate diversity (ants, beetles and spiders), vertebrate occupancy (birds and mammals), seed removal and economic yield of the burnt forest. This project is funded by Generalitat de Catalunya, European Agricultural Fund for Rural Development (FEADER) and Universitat de Girona, and will be developed in 2017-2020.

Project
An average of 65,300 hectares of woodland burned annually in Spain, in the period 1986-2005. Most of these woodlands were managed by clearcutting in the early years after the fire. Despite the severity of both disturbances, fire and logging, there is a lack of information about their combined impact on biodiversity. In recent years researchers have begun to study the mechanisms underlying the response of animal populations to disturbances, but little is known on the role of vertebrates in the regeneration of Mediterranean ecosystems. The aims of the present project are to assess the effects of wildfires and postfire logging on animal populations and on the ecological services they perform. Three indicator groups will be used in this study: (1) cicadas, as a model of arthropods with a hypogean juvenile phase, (2) passerine birds, for their excellent response to vegetation structure, and (3) rodents, because of its dependence on the ecosystem seed production. We also will evaluate seed predation, because it may influence the regeneration of vegetation. The study will be conducted in four generic 'treatments': unburned control pine forests, unmanaged burned pine forests, managed burned pine forests (usually clearcuts, with or without stacking non-commercial timber) and unburned patches inside the fire perimeter, in the eastern half of Spain. The specific objectives of the project are: (1) to compare the abundance, predation and dispersal of the common cicada Cicada orni in the different treatments, in order to assess the species resistance and the possible role of burned forest as ecological traps; (2) to evaluate the population response of shrub-dwelling birds to postfire succession along a gradient of aridity, anticipating a delay in the drier areas or in a future context of increased aridity; (3) to analyze whether the distance to unburned areas and the management of non-commercial timber influences the abundance of rodents and their seed predation rates; The project has a fourth goal, specific of scientific transfer: we will produce and disseminate technical sheets of good practices of postfire forest management with an emphasis on wildlife and the environmental services it provides.
