General presentation

The International Colloquium on thuriferous juniper, are in its fifth edition, will be held in Marrakesh in 2014, after those of Marignac (France, 1997), Marrakesh (Morocco, 2001), Soria (Spain, 2006) and Mont-Dauphin and Saint-Crépin (France, 2011). The regular meetings of this colloquium mobilizes each time a large community of researchers and international experts devoted to this endemic tree species of the western part of the Mediterranean basin. The approached aspects are generally related to its ecology, management and prospects for conservation and its sustainable development.

If this relic species shows a good dynamics concerning its natural regeneration and its growth in Spain and France, it is not unfortunately the case in Morocco and Algeria where this tree is considered as an endangered and vulnerable species, in regression, which could become rare on short-term.

For this fifth edition of the International Colloquium on the thuriferous juniper, the Ecology and Environment Laboratory (L2E), Faculty of Sciences Semlalia Marrakesh (Cadi Ayyad University), is associated with the Laboratory Ecology and Environment (L2E) of the Faculty of Sciences – Ben Msik (Hassan II University, Mohammedia – Casablanca), and the Regional Forest Direction of the High Atlas Marrakesh (High Commissariat of Water, Forests and the Fight against desertification (HCEFLD). The organizing committee proposes to develop themes on the thuriferous juniper and other Mediterranean Cupressaceae. For this edition, besides the traditional aspects developed around ecology and biodiversity, ecophysiological and dynamic of peuplments of junipers, a special attention will be reserved to aspects of uses and ecosystemics services of juniper peuplments in the Mediterranean area and the presence of several threatened species in the Cupressaceae ecosystems, requiring special and adapted conservation measures.

Mediterranean Cupressaceae is known by their great adaptation to extreme environmental conditions once characterized by pejorations order climatic and soil. It is important to have a view on the state of knowledge on these issues, resulting to a great diversity of habitats. The Cupressaceae form a lot of peuplments, alone or in combination with other traditional Mediterranean trees, those peuplments are characterized by pre-forestal to pre-steppic structures, and also steppic structures with. They also cover large areas from the sea on the coast to very high altitudes in the Atlas Mountains of North Africa.

The Cupressaceae are shaped very well, man has made species and spaces dedicated to the production of goods and services déterminanet in his life, especially in mountain areas (timber and fuelwood, fodder for animals breeding, …). The diversity of uses and ecosystem services, help to understand the relationship between trees and human populations, and the operation and management of agroforestry still alive and practiced in our day modes.

Axes and themes of this call for papers for the 5th International Symposium on Juniper thuriferous are:

Theme 1 : Biodiversity and ecosystems of thuriferous Juniper and other Mediterranean Cupressaceae, richness and threats (climate change, overgrazing, pest ….)

Theme 2 : Ecology, Structure and Functioning of the Mediterranean population’s Junipers

Theme 3 : Status and conservation status (technical tools, regeneration conditions, contributions of biotechnology …)

Theme 4 : Uses and local knowledge, Place of the tree in the local and traditional production systems

Theme 5 : various ecosystemics services, Agroforestry and Managment

The 5th International Symposium on thuriferous Juniper will be held at the Faculty of Sciences Semlalia Marrakesh, from April 30 to 4 May 2014. It is a space for exchange and sharing of experience and research findings at national and international levels, in relation with these particular ecosystems of the Mediterranean world.
