"DirfisMushroom P.C.” From Science to the Market
Τhe last 15 years, mushrooms became valuable part of Greek consumers’ diet. New mushroom plants have launched, special cultivated varieties ( Lentinula, Hericium, etc.) have been considerably growing and many young peoplemake a living hunting truffles and wild mushrooms . Αfter the economic crisis of 2009, people living in big cities returned to their villages starting business in forestry or agriculture. “Dirfis mushrooms” was established in 2003 in Mount Dirfis (Euboea) by two agronomists-mycologists (Agricultural University of Athens), Lefteris Lachouvaris and Thanassis Mastrogiannis, representing a success story of the hidden potential of the mushroom and truffles related activities.
"Nectariss": truffle flavour from real truffles
Nectariss aims to create the ultimate truffle flavour from real truffles, addressing three main problems of truffle products:
- the lack of authenticity of existing truffle aromas that are mainly prepared either synthetically or from seafood and vegetables;
- the poor diversity of existing commercial truffle flavours (only few compared to hundreds of truffle sorts);
- the lack of geographical traceability in truffle products and the consequent consumers' misconceptions that truffles exclusively come from few regions (i.e. Alba, Périgord), when they are really valuable resources of most Mediterranean countries.
"Save the Truffle": an initiative to protect and safeguard truffle ecosystems.
City of Alba (Piedmont region, Italy) and the surrounding area, the Langhe and Roero are well known for wine production and some local gastronomic peculiarities, such as white truffle. Unfortunately, over the past 25 years, against a continuing increase in the value of farming products (grapes for wine and hazelnut for chocolate and sweet) and a consequent expansion of cultivated surface, there has been a 30% reduction in truffle-growing areas. “Save the Truffle” aims to promote alternative activities for recovering old truffle-beds and planting new truffle-generating plants.
A comprehensive training program for AMP exploitation
During the last years there has been a growing interest from young people to get involved in the AMP exploitation business. The rich Greek flora and the plenty of abandoned agricultural fields in rural areas offer a great potential in this direction. However, most of the young farmers/entrepreneurs didn’t have a relative experience in the field and there has been many fails and disappointments.
A label for local natural resin
The valorisation of local natural resin in high added value niche markets is a pillar of the French strategy for the revival of the sector. Local natural resin has many advantages over competing products: better quality, generates local jobs, enhances the value of the local forest resource, has a lower environmental impact, etc. These advantages are compatible with the markets sought after but they must be recognised. Can a label allow the local natural resin to stand out from the competition?
A methodology for optimizing Pinus pinea stands from an economic perspective.
The aim is to present a methodology that allows the optimal management of Pinus pinea stands to be determined from an economic perspective when both cone and timber production are considered. Thus, a simulation-optimisation method that implements the stochastic masting model together with an optimisation algorithm would help forest managers to optimise stand management under different price scenarios and market conditions.
Hence , the challenge is to integrate a cone yield model into a simulation-optimisation system which is capable to predict expected cone harvests and seed yields in a certain year, based on the climatic conditions of previous years.

An example of good practice in the aromatic and medicinal plants sector
In order to attract new customers, especially foreign buyers, it is necessary to move away from the usual things and take a step forward. The advancement of technology enables customers to easily access the Internet and inform themselves about various products, and can easily buy it through the web store. It is therefore important to provide customers with something new that is not so common and to tell them the story of the product and to provide them with an overall experience that will go beyond just buying the product.
An example of good practice in the development of the truffle sector
Truffle hunting in Istria began in the mid 20th century when the first written records were recorded about it. Initially, the local population started collecting truffles as it was actually a great addition to their home budget. At this time, the final destination of the truffles were mainly the foreign markets. More recently, the truffle hunters realized that the value can be increased if the product was placed on the domestic market. Thus, in the 1990s, truffle promotion was promoted as a valued product and they quickly realized that diversification of the offer was needed and that additional product value was needed.

Consume chestnut all year? The potential of processed products
Chestnut is a seasonal nut only produced in some regions of Portugal. It is a product whose value is very scattered across the various elements of the marketing chain, with little, and very concentrated in time, internal consumption. It is, therefore, vital to increase and retain its added value and make this market less dependent on the seasonality of the fruit. One way is by promoting new forms of consumption in and out of season, through the processing and innovative uses of the chestnut.

Establishment of truffle plantations - a new form of economic activity in rural parts of Croatia
The European Union defines, through several documents, the cultivation and collection of mushrooms and truffles as the primary product in agriculture. There are a number of measures in place in Croatia to encourage primary agricultural production, but truffle farming is not one of them. In order to offer the rural parts of Croatia new economic activity, which can be extremely profitable, it is necessary to draw up a plan for the implementation of the European Directive and to adapt the relevant laws on the basis of professional and scientific research.
Estimate of the quantity of cork on pile in Tunisia
- Defining a simple and reliable methodology for the quantitative evaluation of stacked cork at cork parks that will serve as a mean of controlling the quantity weighed previously,
- Create a database at each cork park to determine the weight of a cubic meter of cork reproduction.
- Train forest technicians to generalize this method on all cork parks in Tunisia from the 2020 harvest.
Estimating cork stocks through the National Forest Inventory
In the current context in which it can be perceived that climate change is already a reality, one of the issues that most concerns the different sectors dedicated to non-timber forest products (NWFP) is the long-term availability of these forest products, so that a constant supply is ensured. It is important to know the provision of NWFP at the present time in order to know or estimate their future evolution. A key tool in this regard is the National Forest Inventories (NFI). Spanish NFI are a robust, objective and comparable source of information, ideal for carrying out this type of analysis.

EUROPEAN MYCOLOGICAL INSTITUTE (EMI): Towards the Territorial Cooperation of wild edible mushrooms
The EMI’s mission is to support the wild edible mushrooms sector in Europe. The EMI's origin relies on: a) the lack of data and reliable statistics, b) the lack of management (mycosilviculture) guidelines adapted to climate change, c) the lack of a governance and regulation system fitted for controlling collection and market globalization, among others.
For solving those shortcomings, the EMI will support stakeholders in the territorial transitions by means of exchanging good practices, research and innovation, in order to take advantage of the European Cooperation for a joint strategy in opportunities as myco-tourism, agri-food quality products and criteria for the sustainable management of mycological resources.
Evaluation method for the certification of black truffle mycorrhized seedlings
The success of a truffle plantation relies on the presence and abundance of T. melanosporum in the roots of the seedlings the farmers plant to obtain the crop of truffles. Yet, most farmers lack the skills to distinguish a plant with the fungus from one without it. Therefore, independent testing of the plants to be planted is critical to protect the farmers from errors or fraud in the nurseries leading to the sale of plants that will never produce truffles. Our aim was to develop a test that a trained technician could perform in a short period of time to keep the cost low.

The objective of this research is to evaluate the potential of remote sensing data for the modelling of mushroom yields in forests at large spatial scales. Specifically, we want to see if combining remote sensor-based data could represent more accuracy to the current models which are based on climate observations. Showing the potential of remote sensing to model mushroom yields is a first step for the future development of small-scale predictive models.
Experiences and issues in growing and harvesting lavender
For the most part, growing lavender in Croatia comes down to small producers who make it an extra household income. Collecting lavender is the most important part of production because it provides raw material for later processing. Manual harvesting of lavender generate its yield as only the top part of the plant with the highest concentration of essential oil is harvested. The problem with mechanical harvesting is that the machine is not so precise and cannot be adjusted to collect only the top parts of the plant.
Feasibility of small crops of wild medicinal and aromatic plants
The production of medicinal and aromatic plants (MAPs) from wild collection or by cultivation raises environmental, social and economic issues. The demand for a wide variety of wild species is increasing with the growth of human needs and trade. There is an awareness that many wild plants are being overexploited, which many experts recommend incorporating into cropping systems, but several aspects that determine their viability have to be taken into account. An alternative is small-scale cultivation.
Feed Additives: Aromatic Plants and Herbs in Animal Nutrition and Health
Nature has been the source of aromatic plants and herbs for thousands of years, and their use as medicines, enhancers of food aroma, preservatives, or cosmetics is well known from antiquity. However, the great development of animal product industry, in combination with the growing consumers’ demand for higher quality and more environmentally friendly products during the later years, led the food industry to begin to search for alternative solutions in animal nutrition. The introduction of aromatic plants as natural feed additives can be considered as one of them.
Field sampling methods for cork value evaluation before cork debarking
The objective of the current work is the analysis of alternative sampling methods and intensities for estimating cork value before its extraction (price per unit of weight), considering the trade-off between sampling precision and costs. The dataset includes 30 sampling clusters for each of the 6 stands, where the measurement of the tree coordinates in each plot allowed for the simulation of several sampling methods and intensities, and the comparison of the percent errors and sampling costs.
First assessment of cork oak planting and natural regeneration trials in the PACA region
For more than 20 years, plantation and natural regeneration trials have been set up by the CRPF PACA in the Maures massif with the collaboration of volunteer forest owners. The age of some of the trials now makes it possible to obtain transferable results, to guide the management of areas favourable to the cork oak, to allow continuity of monitoring and to develop the setting up of new trials in a context of climate change to be considered.
Forest management adaptation to the production of equally worth non-wood forest products – a practical opinion
In the new context of multifuncionality, the development of management plans integrating both the wood and non-wood forest products (i.e. mushrooms and truffles) for a particular area, aiming to increase the total market value becomes a challenge. In the process of management plan formulation, additionally to the scientific knowledge, also the practical experience of collectors should be taken into consideration.

Greek truffle trees
In the last 15 years, there has been a strong interest in truffles in Greece due to high market prices and the ability to cultivate them. In most truffle plantations in Greece, however, the seedlings come from European countries such as Italy, France and Spain, since there is no domestic production. Taking into consideration the issues of imported plant’s adaptability, biodiversity protection and the risk of introducing unwdesired truffle species, we attempted to create the first Greek truffle trees with Tuber aestivum and T. melanosporum in Greek forest species such as oaks, hazelnuts, etc., in the region of Epirus (NW Greece).
Grevena, the town of mushrooms
Over the last 20 years, an unprecedented phenomenon of micophilia is recorded in Greece, accompanied by remarkable social, economic, cultural and research activity. The focus of this activity is Grevena, a small town of 13,500 inhabitants at an altitude of 530 meters at the northeastern end of the North Pindos National Park, in Western Macedonia. In recent years Grevena has been considered in the consciousness of the Greeks as synonymous with mushrooms and it is recognized today as the undisputed mushroom capital of the Balkans.

Illegal trade & protected species: Salep harvesting and orchid conservation in Epirus (NW Greece)
“Traditional" or "wild" products such as medicinal plants, aromatic herbs and edible mushrooms (including truffles) are part of an emerging mass market that often targets rare or protected species. Orchids, although they are protected by legislation on a national and global scale, are a good example of such a product. Here, we discuss how we can manage the effect of harvesting on wild orchid populations, as our study points to an urgent need to find sustainable management solutions for such species of commercial interest. The dynamics and spatial characteristics of populations are extremely important for applications in conservation; to that end, we introduce an integrated approach that examines the impact of salep harvesting on orchid populations in Epirus (NW Greece).
Impact of irrigation and fertilization on Black truffle (T. melanosporum) fructification
The environmental factors that play a role in the fructification of black truffle are well known. In particular, low water availability during summer period inhibits fruiting. These elements result from observations and tests under controlled conditions. At the time of the study (late 1970s), there was no field trial to determine experimentally the influence of environmental factors in cultivated truffle conditions. A trial on a truffle farm located in south-eastern France was therefore set up in 1979 to clarify the influence of soil fertility and moisture levels on Black truffle fructification.
Impact of Leptoglossus occidentalis on commercial pine nut kernel per cone output
The aim of this work was to quantify the extent of the recent decline observed in pine nut and kernel production. For this purpose, we analysed data from the INIA long-term sample plot network for cone and pine nut production in the four main Spanish stone pine regions. Data series for more than a hundred plots since the last century, previous to the arrival of the bug, were compared with the same series after its arrival. Hence, the collapse in kernel per cone yield since can be quantified, the implied main factors identified, and the evidence of L. occidentalis causality implied analysed.
Impact of postponing cork extraction on the equivalent annual annuity stands, characterized by varying productivity and cork quality
The minimum interval between 2 successive cork extractions from the same tree is fixed by law as 9 years in Portugal. Postponing cork extraction to more than 9 years is an option that results (or not) in a variation of the cork price (for the same structure of cork prices). Site productivity, cork thickness and quality and discount rate contribute to the profitability of the farm, which may be evaluated, for example, by the equivalent annual annuity (EAA). The objective is to apply the SUBER model to evaluate the influence of the cork debarking rotation period (CDR) variation, from 9 to 11 years, on the EAA of different stands by analysing the opportunity to increase the market price of extracted cork.
Impact of the production method on the gentian resource and its regeneration - The sustainable development approach of the Gentian sector
The Yellow Gentian (Gentiana lutea) is a wild plant harvested for its roots at the age of 20 to 30 years old. It is highly valued but little protected. A large part of the production is exported from the source in its raw state. The "Mission for the sustainable management of gentian resources in the Massif Central", a project promoted by the harvesters, helps the different members of the sector to organize themselves to work on good production practices and to ensure the sustainable use of the plant. This work is enhanced by a parallel project to create a "Sustainable Gentian" brand.
Impact of Ultrasound-Assisted Extraction on phytochemical composition in Pinus pinea needles
The aim of this work was to evaluate the outcome of PPT content between ultrasound-assisted extraction and the conventional maceration extraction techniques.
Improvement and development possibilities in cultivation of aromatic and medicinal plants
In most cases, the cultivation and production of lavender in Croatia is not a permanent job, but rather small plantations that generate additional household income. A large proportion of small producers, therefore, sell raw materials or semi-finished products resulting in lower economic profits. If they were able to produce the final product and market it then the economic profit would be higher. Increasing economic profit would certainly be a good incentive to increase production, and thus growing aromatic and medicinal plants would become a core business and would no longer be a hobby or source of additional income.
Improvement of carob cultivation techniques
The carob tree cultivation is handicapped by the poor quality of the seedlings leaving the nursery due to the deterioration of the root system, and poor root quality is indeed a factor of failure when placing plants in the field. The objective of this work is to study the effect of root excision to address the problem of the pivotal nature of the root system and mycorrhization to improve the physiological quality of plants at the nursery stage and increase their chance of success in planting.

Inter-tree competition patterns in un-debarked cork oak stands in Portugal
Assess inter-tree competition in permanent plots established in un-debarked, even-aged stands located in Portugal by i) comparing with the self-thinning line and ii) assessing when stand density affects cork production, iii) stand structure and iv) tree relative growth rate (RGR) pattern over tree size. Spacing coefficient (SC) values < 1.25 are assumed to affect cork production; therefore, detecting when stand density is approaching this value is important. Relative spacing (RS) is easier to evaluate, being important to find the RS value equivalent to a SC = 1.25.
Intraspecific variability and genetic selection of Aleppo pine
Aleppo pine is one of the dominant forest species in Tunisia, favoured by its great regeneration capacity, plasticity, climatic stress tolerance, and multiple products: wood, edible seeds, vegetable seed oil, essential oils from leaves. For these reasons it has been used massively as for reforestation.
But the wide geographical distribution of the species might imply variation in adaptive and productive traits. The use of genetic material well adapted to the environment and better performing allows for valorization of the resource and offers a guarantee of success for new reforestation. In this context, selection of the best provenances from comparative trials is an interesting research issue.
Intraspecific variability and genetic selection of cork oak in Tunisia
In Tunisia, the cork oak is facing various difficulties namely: severe ecological conditions, very heterogeneous stands with variable density, and strong pressure on the forest. Reforestation has become an essential alternative to regenerate old cork oak forests and to support natural regeneration. Selecting adequate plant material with good genetic quality is important to ensure high adaptation to environmental hazards. In this context, the main objective is to explore and evaluate the genetic variability among different stands to select and conserve the best genetic material.

Here we intend to document photographically this traditional knowledge, present the various tools used by cone pickers in the harvesting process and the materials used to build them. This information can be potentialy usefull in other coutries were cone harvesting is made by small, locally operating family firms.
Mapping the potential for truffle production in a natural environment. Development of a method suited to the private forests of the Mont Ventoux (France)
The aim is to map the potentiality of the black truffle production based on the current scientific knowledge already available. To do this, a truffle potential level is assigned to each point of the territory covered with forests. This must eventually allow managers to determine the level of investment in rehabilitating formerly truffle land based on expected potential production.
Maritime pine silvicultural models - what do we know?
In Portugal, traditionally, the maritime pine is the species exploited to obtain resin. The silvicultural models used assume timber as the main product and resin as the secondary product, this being a periodic and annual source of income for the owner. The description of silvicultural models that make timber and resin exploitation compatible is essential and should be based on knowledge.
Mass multiplication of ink-resistant chestnut clones by photoautotrophic micropropagation
Chestnut ink disease, caused by root pathogens (Phytophthora sp. ), induces dieback and mortality in sweet chestnut, C. sativa. Classical biological control can be efficient using ink resistance rootstocks that block the entrance of the fungus.
In this context, selected ink-resistant chestnut clones need to be propagated massively. Here, a method is presented for multplication and rooting clones under photoautotrophic conditions.

Methodology to assess the situation of a medicinal and aromatic plant species to apply a sustainable management in a specific context
A large number of the medicinal and aromatic plants (MAPs) on the market come from wild collection and some of them are being overexploited or exploited without following proper practices. Establishing an adequate management could maintain the use of some species without compromising their conservation and obtain a benefit for the rural community.
In order to collect, it is necessary to evaluate the situation of that species in the place where it is going to be collected to estimate if it can be considered a “resource” or not, and to do it following an adequate methodology.
MICODATASIG: Territorial Information System on the production and management of mycological resources in Castilla y León region, Spain.

The goal is to provide technical information as well as disseminating to the society over the production and sustainable management of the main edible wild mushrooms in Castilla y León region, Spain.
Micophilia in modern Greece. The case of mushroom associations
Greece was until recently considered as a country where mushroom consumption was limited to few species per region. Mushroom were for most Greeks an occasional food, linked to poverty, the "meat of the poor", as they used to call them, that helped rural populations to survive the years of WWII. However, over the last 20 years the picture has changed dramatically as mushrooms are nowadays at the focus of a broader movement, which integrates individual research artistic-creative and entrepreneurial actions related to mushrooms to an activity with a strong social character.
MicoQr: New App for the wild mushroom trading
The main objective of this application is to provide companies in the mycological sector with a traceability management tool for the purchase of wild mushrooms and fresh truffles from the collector or producer.

Odor origin of fresh and processed truffles
With the fluctuation of truffle market, the prices of truffles for restaurants and/or for end consumers can be very variable. This implies the use of less expensive truffle based additions, such as truffle oils and tartufatas (mixture or mushrooms and truffle, used as side dishes, or as a main ingredient for truffle based pates and sauces). Since the odor of fresh truffles are volatile and more mild than their replacements (truffle oils), the objective of this text is to educate the end consumer on differences between the raw truffle material and processed ingredients found in grocery stores.

Optimizing the debarking and cutting schedule of cork oak stands
Cork is a non-timber forest product of great importance due to its excellent characteristics in terms of insulation, elasticity and sustainability. Spain is the second world producer of cork after Portugal. Traditionally, debarking is carried out at intervals ranging from 9 to 14 years, depending on the area. However, the growth of the cork is not constant over the life of the tree, so uneven debarking intervals may be advisable. Despite its economic importance, no silvicultural schedules exist which are based on optimizing the profitability of these stands. This factsheet provides guidelines for the management of cork oak stands when the aim is to optimize economic profitability.
Owners group their forest plots into ASLGF to manage their forest and produce essential forest oils

Pine nuts and chestnuts in your store - Mediterranean or imports from Eastern Asia?
At a first glance, imported Asiatic and genuine Mediterranean pine nuts seem to be similar in size, colour and aspect. Cheaper Chinese chestnuts can also be confused with European chestnuts, when botanic species and origin are not declared on the label, despite this information being mandatory by UNECE marketing standards (2013).
However, aspects such as nutritional values and processing quality, sustainability of collection from wild and of course the taste are highly important. Consumer awareness is vital in this regard. Hence , supply chain actors in the Mediterranean should work together to improve the product profiles of their gourmet nuts, quite distinct from the cheaper imports.

In the Italian forest sector, NWFPs play a fundamental role. In 2011, according to an estimation reported in State of Europe’s Forests , NWFPs were worth 57% more than roundwood. However, statistics on NWFPs sector are scarce and often unreliable. This study, developed in the context of the European project "Startree", represents the first attempt to describe the hidden market related to the mushroom sector in a specific Italian region (Trentino Alto-Adige).
Stone pine (Pinus pinea) grafting
There are several requirements and experiences for a successfull graft, that are reviewed in the following from a practical point of view.
In coastal regions like the Portuguese Alentejo or Catalonian Empordà, grafting is usually performed directly in the field on young plantations, by specialised teams of skilled forest workers. In-nursery grafting on container-raised rootstocks is an alternative, not discussed here, for harsher climate conditions where in situ grafting has a low success rate due to unpredictable spring weather (rain, wind, or late frost in some years, early heat waves in others).
Several handbooks and guides are available online for further consultation.
Stone pine cone production estimated by Terrestrial Laser Scanner
The objective of the present study is to better understand the relationship between tree characteristics and cone production of Mediterranean stone pine.

This tool allows the collection and analysis of field data (soil, climate, sanitary conditions, ...). The vigilance map, by forecasting and locating the risks of decline of the Corsican cork oaks, will help managers take management decisions. The objective is to make silvicultural proposals in order to prevent and limit the risks of dieback.
Summer truffle (Tuber aestivum) potential and development opportunities in Croatia
Croatia is a world famous destination for its truffle collection in wild and the truffle sector is well developed. However, although Croatia is a small country, truffle production is in fact concentrated only in the Istrian region and has not been developed in the rest of the country. In other parts of the country, very few people are involved in collecting truffles (summer truffles) and this is actually more of a hobby for them than a source of income. Therefore, it was important to conduct a survey to determine where summer truffle could be found and in what quantities, and the results of the survey would give us a clearer picture of the possibility of developing the truffle sector in other parts of the country.
Supercritical CO2 extraction technique
After harvesting, the resin takes the form of a homogeneous mixture. Its distillation makes it possible to obtain two products: rosin and turpentine oil. The objective of extraction is to isolate and sample these compounds accurately. In other words, it is a question of having the finest possible selectivity. The second objective is not to alter the molecules and thus take full advantage of its qualities.
Sustainable wild collection of bearberry (Arctostaphylos uva-ursi (L.) Spreng.) in the Pyrenees as a conservation practice

The carob tree in Tunisia: A big varietal richness to preserve and to valorize
In addition to their traditional local use in human and animal food, the fruits of the carob tree have a high commercial value in industrial transformation. The demand for fruits and seeds is growing significantly and their commercial value is increasing. It is also an undemanding species, since it is found in various bioclimatic levels (humid, subhumid, semi-arid and arid) and on poor and skeletal soils. The objective of this work is to explore a panel of varieties to be characterized by describing the tree, fruits, and seeds in an illustrated form.
The chestnut gall wasp in the Portuguese region of Terra Fria Transmontana: Three years of biological control
The Dryocosmus kuriphilus insect, chestnut gall wasp, introduced in Portugal in 2014, represents a serious threat to the national production of chestnuts. Over the years, various pest outbreaks have been identified, which is currently present in much of the Terra Fria Transmontana region, with levels of severe infestation levels. The official reports state, “We are currently witnessing a large and rapid dispersion of the insect and the alarm of the populations, given the damage it is already causing, so, an intensification of the parasitoid releases for these regions should be considered from 2020”.
The Chestnut Round Table of El Bierzo: a different reference of sectoral concertation.

The Round Table is also the coordination and representation body of the chestnut sector in the region.
The co-management of forest resources in Tunisia: A new approach for sustainable development in the sector of AMP
In Tunisia all forest areas are public: in order to use forest products, producers and firms should go through a tendering system subject to Article 18 of the Tunisian forestry code, organized each year by the Tunisian Forestry authority. Small firms and the local populations are facing many difficulties to use available resources legally. The DGF is promoting a new form of sustainable management for forest resources: Concluding contracts between the organized local community and the administration to improve their livelihood and to protect forestal areas.
The cork humidity parameter in the commercialization
The humidity of cork has always been a parameter considered in its commercialization, and is usually expressed as a percentage discount on the total cork quantity. Percentual moisture discounts are usually incorrectly applied, as they are applied directly to the quantity of cork. The same discount applied to cork with different moisture's content can translate into discounts in quantity of cork and not water.
This factsheet intents to inform the cork producers for the relevance of cork sampling for moisture content determination in order to establish the humidity discount in the cork business.
The influence of formation pruning in the cork tree growth rate: a case study.
The formation pruning is an operation usually defined in forest management plans established for cork oak stands plantations. It aims at removing tree branches, usually the lower ones, therefore promoting the development of a long-straight stem, at least up to the expected future debarking height. This will later on facilitate cork harvesting operations.
It is unclear if the pruning intensity affects the tree growth. This factsheet shows the results of a case study where tree growth was compared between trees not pruned, and trees subject to two pruning intensities.
The influence of silvicultural practices on resin production: stand density, tree diameter, and use of controlled fire
Some aspects contribute to the increase of resin tapping costs and, hence, to the reduction of resin yield, namely: the limitation on the diameter of the trees to be tapped imposed by the Portuguese legislation; low stand densities; the necessary control of understory vegetation. Hence, it is essential to evaluate if and how some pine forest management parameters affect the total production of pine resin so it can be increased through silvicultural practices and, thus, compensate for the rise in some costs associated with the resin activity.

Thinning of dense forest stands can increase the Lactarius group deliciosus yields
In 2008, we installed 14 mushroom inventory plots of 100 m2 size in Pinus pinaster forests. The plots were selected to include a range of geographical features (altitude, slope, aspect) as well as variation in tree density and basal area in the conservation area of Poblet. A second set of plots were installed in 2009 paired to the first set of plots. The second set of plots was thinned removing 26 to 77% of the basal area. Mushroom yields were monitored on a weekly basis in the Autumn Season of the years 2008 to 2010 to analyze the effects of forest thinning on the yields of Lactarius delicious group.
Threats and concerns in the management of stone pine in Portugal: insights from a survey among stakeholders
The forest area of stone pine, Pinus pinea, has increased significantly in Portugal in the last 30 years, following the same trend of other Mediterranean countries. At the same time, forest stakeholders report losses in cone production and yield and question on the best management practices to face a already changing climate.
During a Science to Practice event entitled "Stone pine and pine nuts: more knowledge for a better management" held in Lisbon in October 2019, we conducted a survey were we were able to assess the stakeholders' concerns with the pine nut value chain and identify research priorities.
Time and dose of irrigation impact Tuber melanosporum proliferation in young black truffle orchards
Tuber melanosporum, the fungus that produces the priced Black Truffle, is adapted to Mediterranean droughts. Usually the production of truffles increases in years with higher precipitation. This hinted early farmers into watering the orchards to obtain better crops, but, what happens if we water too much? One of the reasons we do not find truffles in forests with abundant rains could be that in wetter conditions other fungi can outcompete T. melanosporum and displace it from the roots of the trees causing the disappearance of the fungus and the end to truffle production.
Tools to reduce the risk of poisoning by wild mushrooms
Poisoning is mostly the consequence of confusion with other edible mushroom species but, in some cases also, of poisonous species collection by people who are totally unaware of the existence of toxic mushrooms therefore not asking for specialized advice before consuming them. Several tools to reduce the number of poisoning by prevention are presented in this factsheet :
- Prevention tools deployed by ANSES (National Agency for Health Security)
- Mobile applications for mushroom recognition

Tree damage control in a cork oak forest
Reducing the amount of damages in the cork oak forest is very important in terms of the sustainability of this ecosystem. Although some of the wounds may have a natural origin (e.g. lightning), most of them have a human source linked to the management operations. The cicatrisation rate of the wounds differs from tree to tree, according to wound size, the tree vitality and the time of the year (5). The establishment of simple recommendations for the forest managers to identify the potential risks associated with the operations and consequences of these wounds can contribute to increase the cork oak vitality.

What are the main variables influencing cork thickness?
- Evaluate the influence of tree size, stand characteristics, debarking coefficients and climatic variables on cork thickness and its evolution between consecutive cork extraction operations, i.e. between successive cork growth periods (cgp). Cork growth is assessed using the cgi, defined as the radial width of the first eight complete years of cork growth after stripping.
- Assess the impact of the increase in debarking intensity on cork growth. Debarking intensity is quantified by the cork debarking coefficient – the ratio of the vertical debarking height to the perimeter at breast height, measured over cork.
What are the pros and cons of bred and commercial varieties versus local ecotypes?
With the aim of knowing the quality and geographical distribution of some aromatic and medicinal species used at industrial level of the Spanish autochthonous flora, for some years projects were carried out for prospecting wild populations of Rosmarinus officinalis, Thymus vulgaris, Salvia lavandulifolia and Lavandula latifolia among others.
The purpose of these projects was to find quality plant material of these species with which to start breeding work in order to obtain commercial varieties adapted to our soil and climate conditions and make them available to the agricultural sector.

Organized in this way, the local boletus sector also intends to fight against illegal harvesting. Producers can thus guarantee the origin and the quality of boletus through traceability and thus better meet buyers' expectations.
“Il Fungo di Borgotaro”: the first P.G.I. (Protected Geographic Indication) labelled wild mushroom.
In the Modenese Apennine (Italy), since the interest towards traditional forest products (as firewood) is declining, also the active forest management is strongly decreasing, especially in marginal areas. In the Taro Valley, the decreased forest management is compromising the conditions required for the development of Boletus mushrooms, a product consumed and appreciated by the local population for centuries. Therefore, there is a need to find mechanisms to re-activate forest management in the area and restore the favorable environmental conditions for the development of this mushroom.
“Lady Truffle”: the “pink” side of truffle
In Italy, the collection of truffles is considered a professional activity mainly for “males”. The “Lady Truffle” initiative, founded by Elisa Ioni, sales manager of a renowned Umbrian truffle company, aims to unhinge this tradition, promoting the hobby of truffle hunting among women, and, in some cases, supporting the transformation of this hobby in a real profession.
