This study was set in three forest habitats of Sidi Reghis Mountain within the province of Oum El Bouaghi (north-eastern Algeria). We conducted the first bird survey in this area using the point count method to describe the composition of woodland breeding avifauna and to analyze the spatial distribution among habitat types (oak woodlands, pine woodlands and oak-pine mixed woodlands). A total of 69 species were observed. One species was recorded only in mixed oak-pine forests, six were found exclusively in oak woodlands and 17 species were found only in pine woodlands. We noted 20 protected species, only one endangered species, and five endemic species to the Maghreb and/or to North Africa. The presence of these species with patrimonial value reinforces the importance of the conservation of Sidi Reghis avifauna. Bird abundance, species richness and species diversity were significantly higher in pure pine woodlands than in mixed oak-pine and oak forests. According to PERMANOVA and ANOSIM tests, and the NMDS plot, the avian assemblages of Sidi Reghis Mountain varied significantly between different habitats. Further, SIMPER test indicated that six of the seven species were responsible for the mean of 50% of dissimilarity between sampled habitats. The dissimilarity between pine woodlands and mixed oak-pine forests was about 50%, in general, and produced by differences in abundance of Common Chaffinch Fringilla coelebs, European Serin Serinus serinus, House Sparrow Passer domesticus, European Greenfinch Chloris chloris, Spotted Flycatcher Muscicapa striata, and Common Blackbird Turdus merula. The differences between pine woodlands and oak woodlands (about 60%) and oak-pine mixed woodlands and oak woodlands (about 50%) were mainly produced by species that were present in just one sampled area, most with preference for pine woodlands. The differences related to pine woodlands are the results from Moussier’s Redstart Phoenicurus moussieri and European Turtle Dove Streptopelia turtur presence.

SUMMARY.— Orchids of Souk-Ahras province (Northeast of Algeria) : inventory, ecology, distribution and conservation concerns.— Algerian orchids became better known during the last years, but certain regions, such as the province of Souk-Ahras (Northeast of Algeria), remain under-prospected. This study is a phytoecological approach, which aims to improve the knowledge of the orchids of this province. A series of targeted surveys has been realized between 2011 and 2015 when we were able to check 7 genera, including 27 species/subspecies and 1 hybrid. Some species are widely distributed throughout the province territory, while others are very localized. Only 18 municipalities among the 26 in the province are concerned by this distribution and are represented by 73 stations including at least one species of orchids. Among the observed taxa 7 are qualified as rare or very rare at national level, at least 3 are Algerian-Tunisian endemics (Ophrys battandieri, Ophrys numida, Orchis pauciflora subsp. laeta) and at least 3 are threatened at global scale (Ophrys atlantica, VU ; Orchis patens subsp. patens, EN ; Serapias lingua subsp. stenopetala, CR). The orchids of Souk-Ahras province often grow on limestone, clayey or siliceous soils, in a subhumid bioclimate rarely semi-arid, at all altitudes of the province, from 500 to 1400 m. This variety of species highlights the taxonomic richness and confirms the interest of prospecting this region that was neglected by orchidologists
Richness and Habitat Relationships of Forest Birds in the Zeen Oak Woodland (Forest of Boumezrane, Souk-Ahras), Northeastern Algeria

Boumezrane's forest is a significant center for biodiversity. Since last year the forest is facing destruction and degradation. Although the forest is recognized as an important area for avian diversity, it has never received ornithological attention. Many studies have been conducted on the relationship of birds with habitat features, however their associations are not completely understood. Hence we need information on the relationship between occurrence of birds and structural components of zeen oak habitats. We examined relative bird abundance by using the point count method and its relationship to environmental descriptors. A total of 68 visits of 39 bird species were recorded in the zeen oak stands. Avian species richness at each point count ranged between four and 14 species. The most dominant families in number of pairs are Paridae (121 pairs), Turdidae (115.5 pairs), Sylviidae (57.5 pairs), Picidae (55.5 pairs), and Fringillidae (43.5 pairs). They cater for more than 70% of the total abundance of the entire community. Using principal component analysis and canonical correspondence analysis methods, we determined that the size of trees with the height of shrub layer is an important criterion for differentiation of the avifauna of Boumezrane. The second criterion is the volume of tree stratum.
