Lawns, pozzines and meadows form a quite original landscapes in our high mountains where cold and very cold Semi-Arid and Sub-humid bioclimates are dominating. Despite their relative small areas, they are rich floristically and phytosociologically. Twenty three associations and/or groupements, six alliances, five orders and five classes: Poetea bul...

Coastal, lagoon, estuarian and marine ecosystems constitute a common landscapes in both Moroccan sides, Atlantic and mediterranean. They are, almost everywhere, very disturbed, near extinction, or has completly disappeared in some places. All the alliances, orders and classes are widely occuring in many countries arroud the Mediterranean. More phyt...

Matorral landscapes are common in Morocco, most of them come from degradation of forest and preforest vegetation. In high mountains, xerophytic shrublets form a very specific matorrals wich could be climacic or not. The main phytosociological structure of all these formations are more or less known. Ninety seven associations and/or groupements were...

Terrestrial halo-gypsophile landscapes occupy quite larges areas in Morocco, especially in Arid and Semi-arid plains and plateaux. Their high phytosociological units seem to be known, but there is still a lot to do in defining, delimiting and classifing a great number of syntaxa among those published up to now. The current inventory contains one hu...

Adiantion capilli-veneris

Ecosystems presented here, in this chapter, are characterised by the absence of forest, preforest and matorral landscapes. They could be a vivace communities occuring in Saharian and Arid bioclimates or annual or perennial in all the others bioclimates; most of the latters are due to degradation and artificialisation of various biotopes. The ecolog...

Violo munbyanae-Cedrion atlanticae

Aquatic and hygrophile Moroccan ecosystems are very disturbed and in constant regression due to a very high human pressure. Almost all the units seen in the country exist in Europe. They do not show a great peculiarities, nevertheless their richness and diversity are quite important : fifty seven associations and/or groupements, four alliances, fiv...

Africa has rich and varied biological resources forming the continent’s natural wealth on which its social and economic systems are based (well established). Most, if not all, terrestrial ecosystems in Africa have already experienced major biodiversity losses in the past 30 years, which has negative impacts on nature’s contribution to people. The p...

There is an increasing need for monitoring schemes that help understand the evolution of the global biodiversity crisis and propose solutions for the future. Indicators, including temporal baselines, are crucial to measure the change in biodiversity over time, to evaluate progress towards its conservation and sustainable use and to set conservation...

Background and aims – North Saharan Acacia woodland is a fragile ecosystem altered by desertification and human activities. Little research has been conducted on the ecology of North Saharan Acacia woodland species. Seed size is a key trait to determine germination success, survival rate and establishment of Acacia woodland species under desert con...

The knowledge on chorology of species is basic for biogeographic and ecological studies and for conservation actions. The data on the chorology of Taxus baccata in Morocco have not been studied. The bibliographic resources, herbarium material, unpublished data of several botanists and the authors’ field notes have been reviewed. Two yew populatio...

The valorization of aromatic and medicinal plants requires perfect knowledge of these plants. In Morocco, several studies have been conducted on aromatic and medicinal plants but no exhaustive list has been developed yet. Through this work, we have tried to inventory, as much as possible, all the plants used for aromatic and medicinal purposes. The...

Morocco constitutes an important centre of plant diversity and speciation in the Mediterranean Basin. However, numerous species are threatened by issues ranging from human activities to global climatic change. In this study, we present the conservation assessments and Red Listing of the endemic Moroccan monocotyledons according to International Uni...

Leaf traits functional relationship is particularly important in plant ecological strategies, but few data are available from Mediterranean high-altitude environments. We analysed leaf general patterns and leaf trait relationships in 84 perennial species on the High Atlas, Morocco. We examined the correlation amongst leaf size, leaf width and lengt...

The presteppic vegetation of the National Eastern High Atlas Park and surrounding areas (Ayachi and Masker mountains) shows 12 associations organized in 2 alliances, 2 orders and 1 class. Ephedro-Juniperetalia is the most important order with one alliance Junipero-Quercion and 12 associations. Pistacio-Rhamnetalia has one alliance Junipero oxycedri...

This study describes the dispersal traits and dispersal patterns of 51 perennial plant species belonging to 19 families in an oro-Mediterranean thorn cushion plant formation on the High Atlas, Morocco. Diaspore type, mass, number, antitelechoric mechanisms and dispersal time were studied with respect to growth forms, dispersal modes and spatial dis...

Flora diversity of the National Park of the Eastern High Atlas and the massifs Ayachi and Mâasker (Morocco). Considering the rare studies on the Eastern High Atlas National Park, Ayachi and Mâasker mountains, the knowledge on the flora diversity of these regions were very insufficient. Their flora is estimated currently 227, 140 and 96 species. The...

Résumé .— La végétation présteppique (s. l.) du Parc National du Haut Atlas Oriental et ses bordures (jbels Ayachi et Masker) montre de nos jours 12 associations qui se rattachent à 2 alliances, 2 ordres et une classe. L’ordre des Ephedro-Juniperetalia est très largement en tête avec une alliance Junipero-Quercion représentée par 12 associations. L...
