Pseudo-alpine grassland ecosystems have started to decline during the past few decades. According to many studies, climate change and abandonment of traditional anthropogenic activities are directly linked to this phenomenon. However, the interaction of these two factors with pseudo-alpine grasslands has not been studied in Greece. The aim of this...

Preservation and promotion of agroforestry systems entails the ideology for more ecosystem services, additional biodiversity benefits and climate change mitigation. Furthermore, farmland and forest landscapes and the consequent benefits to the environment from their combination, enhance the importance of agroforestry systems towards sustainable env...

Wood-pastures are among the most valuable types of farmland for ecosystem services, including biodiversity, landscape, soil protection, water management and cultural values. This paper reviews the scientific literature regarding the dynamic role and importance of plant, fungal and ruminant communities in Mediterranean wood-pastures and assesses the...

Rural Europe encompasses a variety of landscapes with differing levels of forest, agriculture, and agroforestry that can deliver multiple ecosystem services (ES). Whilst provisioning and regulating ES associated with individual land covers are comparatively well studied, less is known about the associated cultural ES. Only seldom are provisioning,...

It is estimated that olive groves cover an area of 700,000 ha in Greece, with 124,311 ha forming agroforestry systems combined with various crops or pasture, established in the understory of the trees. A lush understory grows under the olive trees, consisting mostly of herbaceous vegetation for animal grazing, vegetables and various crops such as c...

Agroforestry and small-scale traditional farming systems as well as multi- functional forest landscapes survived in many rural areas in Europe (both in mountains and islands) that escaped the large scale agricultural transformation that has been supported by the EU Common Agricultural Policy (CAP). How can we build a more resilient rural economy in...

Juniperus communis ssp.nana). Σκοπός της έρευνας ήταν η μελέτη των χειρισμών που εφαρμόστηκαν σε απομίμηση των παραδο-σιακών αυτών δραστηριοτήτων για τη χλωριδική ανόρθωση των ποολίβαδων. Συγκε-κριμένα, το φθινόπωρο του 2013 έγινε προδιαγραμμένη καύση του νανόκεδρου και το φθινόπωρο του 2014 κοπή των ανταγωνιστικών ποωδών φυτών. Επιπλέον, σε περιοχ...

Most farm-based agroforestry projects focus on the integration of trees on arable or livestock enterprises. This paper focuses on the integration of understorey crops and/or livestock within high value tree systems (e.g., apple orchards, olive groves, chestnut woodlands, and walnut plantations), and describes the components, structure, ecosystem se...

Biodiversity is a heritage of an ecosystem and especially refers to the diversity within and among living organisms, gatherings of living organisms, biotic communities and processes. It contributes a wide range of essential services to the sustainable function of all ecosystems. In this review, we summarize literature about the terrestrial biodiver...

The role of Natura 2000 network is to ensure the long-term survival of Europe's most valuable and threatened species and habitats. Ecologically valuable forest ecosystems are often owned or managed by private forest owners. Natura 2000 benefits communities by enhancing tourism, regional brands and marketing. In private forests, however, its restric...

An accurate and objective estimate on the extent of agroforestry in Europe is critical for the development of supporting policies. For this reason, a more harmonised and uniform Pan-European estimate is needed. The aim of this study was to quantify and map the distribution of agroforestry in the European Union. We classified agroforestry into three...

This report (updated in August 2016) is an output from work-package 1 which aims to understand the context and extent of agroforestry in Europe. In an earlier report, den Herder et al (2015) reviewed literature sources to provide a preliminary estimate of the extent of agroforestry in Europe. That report (which collected only limited data from some...

Several management actions are applied to restore ecosystem services in degraded Mediterranean rangelands, which range from adjusting the grazing pressure to the removal of grazers and pine plantations. Four such actions were assessed in Quercus coccifera L. shrublands in northern Greece: (1) moderate grazing by goats and sheep, (2) no grazing, (3)...

Tree growth, understorey characteristics and soil parameters were evaluated in a silvopastoral system in northern Greece at seven and twelve years after its establishment. The experiment was laid out in 1992 and included three understorey treatments (grass, legume and control-unsown), two tree species-sycamore (Acer pseudoplatanus L.) and Scots pin...

The orchid family (Orchidaceae L.) is one of the richest plant families in the world, including at least 24,000 species and subspecies. In Greece the number exceeds 200 taxa, while the endemics are 50 or more. These numbers often change, as new species are described or others considered until recently as endemics in Greece, are recorded in neighbou...

Between 2003 and 2004, 264 face-to-face interviews were undertaken to determine farmers’ perceptions of silvoarable agroforestry across 14 sample areas in seven European countries. Across the 14 sample areas, 40% of respondents had heard the term “agroforestry” and 33% then defined it as an association of trees with crops or livestock. By contrast...

Agroforestry systems are a traditional land use practice in Greece. They are widely distributed all over the country and constitute important elements of the rural landscape. They include all three types of systems: silvoarable involving trees and crops grown on arable land, silvopastoral involving trees and pasture/animals grown on forest and arab...

Mixed systems of agriculture incorporating combinations of trees and crops have formed key elements of the landscape of Europe throughout historical times, and many such systems continue to function in the present day. In many cases they represent formerly widespread traditional systems in decline and a number have already become extinct or exist o...

These proceedings contain 123 papers which are divided into 5 main sessions. The first session includes the characterization of silvopastoral systems in a global context while the second session deals with the effects of the management tools on the productivity and quality of silvopastoral systems. The ecological implications of the silvopastoral s...

The interaction between understorey plants and trees in a young silvopastoral system was studied in a sub-humid Mediterranean environment with cold winters in northern Greece. The experimental design was a split-split plot with three replications and included: three understorey treatments (grass, legume and control), two tree species (Acer pseudopl...

A new study to address the biosphere-atmosphere exchange of ammonia (NH3) with grasslands is applying a European transect to interpret NH3 fluxes in relation to atmospheric conditions, grassland management and soil chemistry. Micrometeorological measurements using the aerodynamic gradient method (AGM) with continuous NH3 detectors are supported by...
