Abstract Mushrooms are an important product of the pine stands of the Central Pyrenees of Catalonia. In places where the microclimate is reasonably moist, the value of mushrooms may be clearly higher than the value of timber production. This study examines the optimal economic management for both timber and mushrooms in even-aged Scots pine and Black pine stands in Catalonia. Empirical mushroom yield models were integrated in a stand growth simulator, which was linked with an optimization algorithm ...

Summary In the last two decades, stand decline and increased mortality has affected silver fir ( Abies alba ) forests in the Spanish Pyrenees. Simultaneously severe occurrences of the root rot fungus Heterobasidion annosum s.l. and of the mistletoe Viscum album have been reported. We aimed to improve the understanding of the epidemiology of both pathogens in our region. All H. annosum isolates found on silver fir were typed as H. abietinum . H. abietinum was more frequently observed where cuttings had ...

Oxytetracycline-penicillin (combined), captan, fumigillan and dimethoate-carbofuran (combined) were applied to forest soils to test their effects on soil populations of active and total bacteria, active and total fungi, protozoa, nematodes and microarthropods. All biocides significantly reduced the populations of target organisms, except dimethoate-carbofuran, which failed to reduce the number of microarthropods. All biocides also affected populations of non-target organisms. Oxytetracycline-penicillin ...

summary Inoculation of planting holes with small amounts of soil from a mature forest or a plantation can improve formation of ectomycorrhizas on Pseudotsuga mensiesii (Mirb.) Franco seedlings in degraded eleareuts in southwestern Oregon. To determine the component (s) of transferred soil responsible for increased ectomycorrhiza formation, we treated soil from a clearcut, a mature forest, and a plantation with one of the following: fertilizer to test for the effect of nutrients, dimethoate and carbufuran ...

Mushroom picking has become a widespread autumn recreational activity in the Central Pyrenees and other regions of Spain. Predictive models that relate mushroom production or fungal species richness with forest stand and site characteristics are not available. This study used mushroom production data from 24 Scots pine plots over 3 years to develop a predictive model that could facilitate forest management decisions when comparing silvicultural options in terms of mushroom production. Mixed modelling ...

Relative quantification of DNA from Tuber melanosporum mycelia was performed by conventional and real-time PCR in soil from trees in three truffle orchards of different ages to determine: (1) whether burn appearance is related to the amount of T. melanosporum mycelium in soil, and (2) whether productivity onset and truffle production are related to (a) the amount of T. melanosporum mycelium in soil, (b) tree height and diameter, (c) burn extension and (d) surface rock cover. The burn seems to appear only ...

Multiple-use forestry requires comprehensive planning to maximize the utilization and sustainability of many forest resources whose growth and productivity are interconnected. Forest fungi represent an economically important nonwood forest resource that provides food, medicine, and recreation worldwide. A vast majority of edible and marketed forest mushrooms belong to fungi that grow symbiotically with forest trees. To respond to the need for planning tools for multiple-use forestry, we developed ...

Edible and medicinal fungi have become increasingly important non-wood forest products in Spanish forests. Annual mushroom collections increase the economic value of forests and provide income to local collectors and marketers. Most of the species are ectomycorrhizal fungi that are essential for seedling establishment and long-term nutrition of the trees. Due to the economic depression in the local wood markets of the Pyrenees, forest managers are evaluating alternatives to timber management for ...

Among the environmental services provided by Mediterranean forests, wild mushroom picking is particularly appreciated. Where access to the forests is free, and when the property rights to the products that can be picked from the ground are not clearly assigned, forest owners bear a cost, in the form of forest damage by pickers, and receive no benefit. These owners therefore have little incentive to provide the public with more or better forests, however socially desirable this would be. If the value ...

Our objectives were (i) to develop a molecular method to detect mycelia of Tuber melanosporum (black truffle) in soil and (ii) to test for mycelial distribution around two truffle-bearing Quercus ilex trees in a truffle orchard. Isolation of total DNA from soil was performed, followed by PCR amplification with T. melanosporum-specific primers and restriction analysis. To address the detection sensitivity level, soil samples were inoculated with known amounts of gleba of T. melanosporum. The detection ...

The Périgord black truffle is an exclusive culinary delicacy, but its Mediterranean harvests have declined, despite cultivation efforts since the 1970s. The role of long-term irrigation, symbiotic fungus-host interaction, and microbial belowground progression remain poorly understood, because generally too short experimental settings miss the necessary degree of real world complexity and reliable information from truffle orchards is limited. Here, we conduct the first dendrochronological and wood ...

Predicted changes in global climate might negatively affect the soil microbiome and associated ecosystem processes in Mediterranean forests. Forest treatments, such as forest thinning, have been suggested to mitigate climate change impacts on vegetation by reducing competition between trees, thus increasing water availability. Studies addressing the combined effects of climate and forest thinning on belowground fungal communities are still scarce, being fundamental to elaborate adaptive strategies ...

Abstract Over the past 15 years, 3 million hectares of forests have been converted into shrublands or grasslands in the Mediterranean countries of the European Union. Fire and drought are the main drivers underlying this deforestation. Here we present a conceptual framework for the process of fire‐induced deforestation based on the interactive effects of fire and drought across three hierarchical scales: resistance in individuals, resilience in populations, and transitions to a new state. At the ...

Soil fungi are fundamental drivers of forest ecosystem processes. Soil physico-chemical parameters and vegetation features such as host type or stand structure can affect soil fungal communities. However, there is a lack of comprehensive studies describing the relative importance of niche processes (soil physico-chemistry and forest structural drivers) versus neutral processes (geographical distance) driving soil fungal community assemblages, especially in less-studied drought-prone ecosystems such ...
