RÉSUMÉ. Richesse et diversité floristique de la suberaie de la Mamora (Maroc). L’étude vise la quantification de la richesse et de la diversité floristique de l’écosystème à chêne - liège de la forêt de la Mamora sur la base de transects et relevés floristiques répartis selon un échantillonnage stratifié et systématique dans différentes formations végétales préalablement distinguées. Les résultats montrent que l’écosystème renferme 62 familles, 261 genres, 408 espèces, sous-espèces et variétés. 35 taxons sont très rares et 29 rares. 18 taxons sont endémiques, 1 très rare et endémique et 4 rares et endémiques. L’étude a, par ailleurs, permis de révéler la disparition totale de Erica arborea et E. scoparia de cet écosystème et de définir le spectre biologique de la région d’étude qui se caractérise par une nette dominance des thérophytes (50.5%).Mots clés.

The survey aims to quantify the floristic richeness and diversity of the Mamora’s forest oak-cork ecosystem on the basis of transects and floristic samples distributed according to a stratified and systematic sampling in the different plant formations previously distinguished. The results show that the ecosystem contains 62 families, 261 genders, 408 species, subspecies and varieties : 35 very rare taxa , 29 rare taxa ; 18 endemic taxa, 1 very rare and endemic taxa and 4 rare and endemic taxa. The survey has, otherwise, permitted to reveal the total disappearance of Erica arborea and E. scoparia from this ecosystem and to define the biological spectrum of the studied region, wich is characterized with a clear dominance of therophytes (50.5%).Keys words.

Cork Oak Forest

Cork oak (Quercus suber) is a declining woodland species across the island of Sardinia, despite its former economic importance for wine production and its significance for biodiversity. In particular, cork oak forests (COFs) on the island have seen a 29% decrease in the past 45 years. A spatial GIS model was developed to determine suitability for the expansion of cork oak forests on the island. The model uses a set of simple spatial decision rules based on principles of landscape ecology and expert opinion to assign a suitability score for pure cork oak forests to every land use parcel in Sardinia. These rules include the type of existing land parcel, its size, distance to existing cork oak forest, and the area of seminatural habitats in its neighborhood. This was coupled with a map of landscape types to assist with the development of policy for the protection of cork oak forests across Sardinia. The results show that there is an area of 116,785 ha potentially suitable for cork oak forest expansion in Sardinia, with the largest area of potential habitat on granitic mountains. There is a substantial overall agreement (Cohen’s kappa = 0.61) between the suitability map produced and the historical reference map. The model is flexible and can be rerun to reflect changes in policy relating to agri-environmental targets for habitats and species.

The analysis of the floristic diversity of forest massif “Hafir-Zariffet” in the Tlemcen National Park has revealed the existence of 211 taxa which belong to 65 families and 164 genera. The number of taxa endemic and/or rare includes: 1 endemic algerian, 7 algero-moroccan, 11 ibero-algero-moroccan, 7 are endemic in North Africa and 11 are endemic in Iberian Peninsula and North Africa. The number of rare taxa is 26, 9 are at the same time threatened. Urgent efforts are required to preserve the cork oak as well as endemic species confined to it.Key words.

SummaryCharacterising the habitat use of released captive-bred birds is required to help optimise future avian reintroduction programmes. The critically endangered Double-spurred Francolin Francolinus bicalcaratus ayesha is endemic to north-west Morocco, where it inhabits forests of cork oak Quercus suber. To improve the viability of this threatened population, 300 captive-bred francolins were released into a game reserve, and post-release monitoring was conducted. This study aimed to identify habitat variables determining the habitat selection of the Double-spurred Francolin. Auditory detection was used during transect surveys of calling males to locate birds and their habitat occupation. Comparison of occupied and random plots showed that this bird is found mostly in flat topography with high cover of shrubs and dense cork oak trees, and close to the release site and water points. Conservation of Double-spurred Francolin depends on the choice of the release point within the cork oak forest, which should be in proximity to suitable cover of cork oak trees, shrubs and water points. Such choices would allow a rapid adaptation to prevailing conditions within release sites. Further multi-scale studies are needed to improve our understanding of the effects of ecological factors on the processes of habitat selection by this endemic subspecies.
