“…According to estimates by Kafi et al (2015) [33], this region has approximately 199,240 ha of forest cover, primarily composed of Quercus suber L., Q. canariensis Willd., Pinus halepensis Mill. and P. pinaster Aiton [30,34], contributing to its remarkable richness. The meteorological stations of Guelma and Souk Ahras have provided annual climate readings for the period (2019-2023) with precipitation ranging between 420 and 425 mm Land 2024, 13, 210 3 of 22 for the GZE, GZN, TRC, TRN, and MJN wetlands and 698 and 700 mm for MTG, BTH, TAR and BRG.…”

This in-depth floristic study, conducted from 2019 to 2023 in nine temporary wetlands in the Guelma and Souk Ahras provinces, northeastern Algeria, aims to highlight the natural heritage of the region by analyzing the floristic composition in relation to environmental conditions. To achieve this goal, comprehensive inventories were conducted, revealing the presence of 317 species belonging to 64 botanical families and distributed across 204 genera. The plant diversity at each site was assessed using various biological indices, with a particular focus on the Taxonomic Distinctiveness Index (TDI) to determine the influence of environmental factors such as fires, altitude, overgrazing and agropastoral activities on biodiversity. The results highlighted the dominance of therophytes (43.22%) and the prevalence of the Mediterranean assemblage (66.25%). Moreover, 8.83% of the species were endemic, 1.89% were protected by Algerian legislation and 1.26% were listed on the IUCN Red List. The study identified Priority Conservation Zones (PCA) where the preservation of ponds, particularly MTG, TRC, BTH, and GZE, is crucial. Additionally, floristic and ecological boundaries between ponds were identified, highlighting marked biological similarities between certain pairs and notable isolations, particularly evident in the case of BTH with a significantly high TDI. These results underscore the critical importance of the studied region, emphasizing the need to integrate its floristic biodiversity into conservation efforts to enhance overall ecological integrity.

RésuméCette étude vise à mieux connaitre le patrimoine floristique de l’Algérie. Dans ce travail nous avons dressé une liste des orchidées de la région de Tlemcen grâce à une série de prospection réalisée entre 2006 et 2018 et qui s’est soldée par l’inventaire de 11 genres, comprenant 48 taxons dont 329 espèces et 2 hybrides. Des cartes de répartition et des données écologiques ont été établies pour chaque espèce afin d’aider à les retrouver pour des éventuelles recherches. Certains taxons présentent une large distribution à travers la région de Tlemcen, alors que d’autres sont très localisés. Parmi les taxons observés, 27 sont qualifiés de rares ou très rares à l’échelle du pays. Mots clés: Orchidées, région de Tlemcen, endémique, protection, chorologie. SummaryOrchidaceae of the region of Tlemcen (Algeria).This study aims at knowing better floral heritage of Algeria. In this work we so raised a list of the orchids of the region of Tlemcen en thanks to a series of prospecting realized between 2006 and 2017 and which ended in the inventory of 11 genres including 48 let us taxa among which 29 species and 2 hybrids. Maps of distribution and ecological data were established for every species help to find them for possible look for. Some let us let us tax present a wide distribution through the territory of the wilaya, while others are very located (localized). Among tax them observed, 26 are considered as rare or very rare on the scale of the country.Key words: Orchids, Tlemcen region, endemic, protection, chorology.

This work aims to better to know the floral richness of Tell region (Saida, western of Algeria) particular orchid flora. This inventory was started in 2017-2022; It’s based on random samples, in spring and autumn. The surveys directly targeted open areas (Northern Saida). This inventory revealed the presence of 11 orchids including 2 species, 6 subspecies and 2 varieties. The 11 taxa belong to 5 genera: Anacamptis, Dactylorhiza, Himanthoglossum, Orchis and Ophrys. Some taxa are rare, endemic and are protected (threatened) by the IUCN Red List as a near threatened species and/or are endemic and protected in Algeria, rare species in the Tell region. A stationary precision made it possible to know the distribution area of each identified taxon. Due to anthropogenic threats, a strategy to protect habitats seems very urgent.
