The Myrtus communis L. is an endemic species appreciated traditionally for its medicinal and aromatic properties. Improving the multiplication and propagation methods of the common myrtle is the most important objective of this paper. The work was held to conserve the species and its decreasing populations due to the lake of management, overcutting and Anthropozoic pressure in its location area.
The objective of the present study is to better understand the relationship between tree characteristics and cone production of Mediterranean stone pine. This was achieved by quantifying the gain in using detailed crown metrics in estimating cone production at individual tree level (number of cones per tree and average cone weight). Models based on traditional variables (tree size and stand characteristics) were compared to models that relied on crown metrics extracted from TLS data. The resulting models should help owners and managers to better predict cone production.

• Provide some indicators of the risks that could weigh on these species.
The aim of the project is to develop an industrially producible bio-sourced varnish based on gum rosin and linseed oil, inspired by the ancient know-how of the violin maker Antonio Stradivari (1644-1737). The difficulty is to meet the specifications of an industrial manufacture while achieving high performance of the varnish.
Resin is a natural product that has multiple applications and is highly demanded in the chemical industry. As a non-timber forest product, exploitation of the abundant pine resin in Tunisian forests (50% of the forest area) can contribute to a bioeconomy and can generate additional income for forest populations.
The autonomous resin tapper trade is precarious due to factors such as the seasonality of the activity, the fluctuation of resin prices, some resination campaigns are even below the profitability threshold, and the difficulty of accessing complementary sources of income.
To support the sustainability of the resin tapper job, this guide proposes a model of territorial contract tailored to this group of workers, which can be used by public administrations to supplement their income through the remuneration of specific commitments and recognition of the positive externalities generated...
The objective of the project was to implement in France a classical biological program against the chestnut gall wasp, Dryocosmus kuriphilus (Dk), using releases of the exotic parasitoid Torymus sinensis. The expected outcome of this project were (i) the permanent establishment of the parasitoid and (ii) an efficient and long-term control of the pest.
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...
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...
This project aims to assess the effects of FSC certification on the conservation of cork oak woodlands namely how certified conservation zones (areas of lower management intervention) affect oak natural regeneration, understory shrub diversity, conservation of water streamlines and associated bird diversity. In addition, at a larger scale, the project also aims to identify geographical areas of conservation value for biodiversity and ecosystem services. Resulting information will contribute to identify target areas to implement payment for ecosystem services schemes using FSC certification...
This study presents an assessment of essential oils amounts and quality obtained from Tunisian Salvia officinalis and its variations regarding the plant organs, the harvest season and the plant's drying process conditions. Three drying processes were tested, natural air drying, hot air convective drying at two temperature 40 and 60°C and microwave drying at 218 W.
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...
The cork oak forest management involves interventions in the understory with the following objectives: reduction of the fire risk, operationality of the cork harvesting, promotion of cork oak recruitment and reduction of competition for water and nutrients between trees, herbs and shrubs. The techniques currently available for the forest producer to carry out these operations are: the practice of grazing and / or mechanized interventions (harrowing, shrub cutter, shredding). The choice among several mechanical techniques should consider cork oak sustainability and the potential impacts...
In light of the great global interest in PAM as a source of active ingredients. So, it is important to investigate the impact of seasonal variation on Rosmarinus officinalis, Erica Multiflora and Cistus monspeliensis by evaluating of some biochemical responses in three sites Mount of Zaghouan (DZ), Mount of Mansour (DM) and Mount of Sarej (DS) and to compare their behavior in the three seasons (spring, summer and autumn).
The aim of this work was to evaluate the outcome of PPT content between ultrasound-assisted extraction and the conventional maceration extraction techniques.
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.

The objective is also to enhance the picking profession by disseminating its knowledge and know-...
The thickness of cork oak trees varies highly, even when they are located in the same geographical location or stand. The objective was to research how climate variables affect different trees within the same site, for which precipitation and temperature variables were considered. The response variable was the cork growth index (cgi) – the cork thickness of the first eight complete growth years were measured after boiling. The differences between trees were characterised by nine different cork thickness quantiles, from lower (thinnest cork) to higher (thickest cork).
We have projected for the ﬁrst time to study the impact of geographic variation and environmental conditions on the chemical composition, the antioxidant activities as well as the antitumor activity of two of Pinus halepensis Mill. Oils provenances, distributed under different ecological conditions in Tunisia.
Stone pine (Pinus pinea L.) cone harvesting in Portugal continues to occur trough the traditional way, that is, by specialized workers that climb the trees and remove the cones by hand using special tools.
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.
Along with the latest advances in the resin sector for improving resin production, such as forest tree breeding, innovative harvesting technology, etc, prescribed fire is also analysed as a tool for increasing resin yield in Pinus pinaster stands. The results of this study are summarized below.

3: Use the individuals showing the best resistance capacities against ink disease (“elite trees”) as seeds producers in seed orchards.
The expected results are:
- Reconquest and renewal of the actually declining chestnut orchards
- Decrease of...
The Periploca angustifolia is a native shrub widely distributed in the Mediterranean region. This species is threatened because of its medicinal properties, its pastoral interest and its role in the fight against soil erosion. The main objective of this work is to master the germination and multiplication techniques of Periploca angustifolia L.
This example show cases the possibility that some private companies, interested in processing cork, wood chips and wood, take-up forest management on behalf of private or public forest owners in a new private-private or private-public business model. This ensures the conservation of largely abandoned cork oak woodlands. The agreement foresees the possibility for the processing industry to ensure the mid and long-term supply of cork.
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...
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.
Informing policy makers at national and EU level about the short and long term consequences of forest bioenergy production and its trade-offs for other ecosystem services.
The aim of this work was to evaluate the effect of treated wastewater short and long-term irrigation on essential oil composition from E. camaldulensis Dehn in order to detect allelopathic impacts on seed germination and seedling growth of Amaranthus hybridus L, Chenopodium album L, Echinochloa crus-galli (L) Beauv and Lolium perenne L as important weeds on many crops.
It is not possible to separate the cumulative effect of: climate change, soil conditions, cultural practices and the presence of biotic agents, the way the trees die, due to progressive decrepitude or sudden death, as well as the physiological processes involved that are necessarily different and must be treated differently when deciding on the urgency and the period of dead trees felling, the management of the wood material, forestry residues and subsequent options for afforestation, natural regeneration or conversion to another species.
This factsheet aims to highlight some of the...
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.
The standardisation study facilitates the inclusion of wood from resin tapped pines in the Spanish standard UNE 56544 (Visual classification of sawn wood for structural use. Coniferous wood), in order to favour its use and marketing as structural wood.
Simultaneously, the study compares the physical-mechanical properties of resinated Pinus pinaster wood against non-resin wood under the same normative parameters (UNE 56544), so that the technical buyer can evaluate which product is the most suitable for the intended application.
Chestnuts are an extremely important product for the Portuguese region 'Terra Fria Transmontana', representing one of the most profitable crops today. Its commercialization is still done based solely on caliber, an essential characteristic to satisfy a consumer little informed about the diversity of existing varieties. Longal is a traditional regional variety from PDO Castanha da Terra Fria, with excellent characteristics for fresh consumption and the processing industry. It is important to work on its promotion with consumers and producers.

Zgougou is considered one of the most interesting NWFP due to socio-economic role and commercial value. Aleppo pine seed oil can be extracted as for nutrition, or for medicinal and cosmetic uses.
The present work studies the conditions of exploitation of seeds in the forest, the yield of vegetable oil extracted, its physicochemical qualities and the possibilities of valorizing the press cake obtained after...
Pine species are considered as a natural source of antioxidant compounds. Pinus nigra Arnold is one of the most known medicinal plants in the Mediterranean countries. The aim of this study was to determine, for the first time, the bioactive compounds such as the total phenols, flavonoids and tannins and to evaluate the antioxidant potential of needles collected from nineteen samples corresponding to different provenances of black pine from different regions which have been planted and grown in Northwestern Tunisia.
Analysing the expression of socio-cultural values in a coastal setting, considering the contribution that ecosystem service approaches can make within the land use or spatial planning arena. People attach socio-cultural values to the natural environment just as they do to other aspects of life. Cultural ecosystem services are strongly influenced by these values and provide tangible and intangible benefits to people when they interact with nature. Often in decision making the less tangible cultural ecosystem services benefits are overlooked and unaccounted when considering the overall value...
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...
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...
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

34 case studies were planned by the H2020 PEGASUS project in different farming and forest systems and along the supply chain in 10 EU countries, to:
- examine the issues faced in ensuring effective provision of public goods/ecosystem services from farming & forest activities; and
- find solutions to enable the economic social and environmental sustainability of the EU’s farmed & forest areas.
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.
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.
In the past, herbs were the only cure for the disease, and learning about herbs was based only on human experience. They found the medicine in their environment, where they learned to recognize the plants and to determine how to use it. Knowledge and experience have been passed down from generation to generation, so today there are many who, thanks to the knowledge and experience of their loved ones, have become successful users and growers of medicinal plants, although unfortunately some of the knowledge about medicinal plants has probably fallen into oblivion, given that no one ever...
This factsheet aims to highlight the interannual variation of the pine cone dimensions and present some factors that explain it, in order to contribute for the future establishment of silvicultural measures than can lead to a decrease in that variation, by promoting the conditions for bigger pine cones or selecting more suitable Forest Reproduction Materials (FRM) .

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...
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.
Describe the key elements constituting the natural resin sector in a historical resinous region, underlining the social, environmental and economic importance of resin harvesting, and its potential as an instrument of local development and environmental conservation.
In the life cycle of cork, carbon dioxide (CO2) and methane (CH4) gases are released from biological material combustion or decomposition as well as from burning fossil fuels. The biogenic carbon emissions from forest-based products are usually not included because they are released into the atmosphere during the processing and end-of-life stages. The carbon footprint for the cork sector should be considered at different stages, from forest management activities, across the manufacturing processes and product distribution, to the product end-of-life.
We mapped ecosystem services at different scales in Costa Rica and analyzed the spatial congruence and tradeoffs between biodiversity and several services, by considering the biophysical potential of service provision and socioeconomic demand. We also analyzed tradeoffs over time.
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,...

3. Is there potential for coordinated business investment in natural...
Aleppo pine (Pinus halepensis Mill.) is one of the most drought-tolerant pine species and it is distributed over large drought-prone Mediterranean regions. The determination of the water balance of the soil-crop-climate and its fluctuation is difficult to achieve, due to the spatial variation in site conditions (Schiller and Cohen, 1998). The objectives of this study are to (1) estimate crop water requirements (ETc) and actual evapotranspiration (ETa) of Tunisian Aleppo pine and (2) study the impact of climate change on water balance, using the WEAP-MABIA Module (Yates et al.,...
In rural areas of Tunisia, the average wood consumption per household and per year is between 1.8 and 5.9 tones. The highest consumption was noted in the forest regions of Sejnane, Boussalem and Jendouba. Results show that traditional bread baking represents 60 to 70% of the percentage of wood consumed in households. With a view to satisfying the increasingly growing needs for ﬁrewood and charcoal in rural areas, we have initiated a selection research program oriented towards more intensive wood production including wood that can be used for energy purposes. In this work, we propose to...
The traditional method of resin tapping is a very time-consuming activity since it requires the resin tapper to visit each tree every 10 to 15 days during the season. In order to develop more efficient methodologies, the results of the first experiments carried out using the new drilling technique are presented.
In Tunisia, handicrafts based on local wood are mostly from olive wood. Due to its physical, mechanical and aesthetic qualities, olive wood is highly sought and appreciated by artisans and buyers. In front of the growing demand for this wood, local people do not hesitate to resort to illicit cuts to satisfy the needs of the market. The objective of this study is to search for forest species offering wood qualities that rival those of olive wood and that can be valorized for artisanal use.
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.
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.
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...
Cork oak ecosystems have been experiencing a serious decline in the last decades attributed to different causes, including wildfires. After fire trees may become particularly vulnerable to forest pests, which may further affect the vigor of surviving trees and give rise to massive dispersing offspring affecting surrounding areas, but this was rarely assessed in Mediterranean oak ecosystems. Thus, the objective of this study was to assess the presence and dynamics of xylophagous insects on cork oak forests following fire in central Portugal.
The subject of this research is aromatic, medicinal and spicy cultures as part of cultural heritage and tradition. The research goal is to examine the possibilities of developing cultural, rural, health and wellness tourism based on cultural heritage.
