This study is an avifaunistic diversity assessment was carried out in the Merine forest, Sidi Bel Abbes (Northwest Algeria). During three years (2019-2021). The major objective of our investigation is to inventory avian species and to define their phenological categories. Among the important results is a record of, 71 species of bird, belonging to 17 orders and 28 families. The Passeriformes are the most noted with 43 species, distributed across 15 families, of which the Muscicapidae is the most represented with 10 species. The phenological categories indicates that the majority of this species are resident breeders (65 %), 21% are migrant breeders and 14% are passing visitors. Depending on trophic status, 32% are polyphagous, 27% insectivorous, 17% carnivorous, 15% granivorous and 8% omnivorous. In addition, we noted that, 31 species are protected by Flat 12-235 in Algeria, with one species (Falco naumanni) protected by the Ordinance 06-05. Internationally and one species protected according of the IUCN red list (Streptopelia turtur). The Merine forest is shelter to five species endemic to North Africa: Barbary Partridge (Alectoris barbara), Levaillant's Woodpecker (Picus vaillantii), Moussier's Redstart (Phoenicurus moussieri), Tristram's Warbler (Sylvia deserticola), African Blue Tit (Cyanistes teneriffae).

Abstract The narrow-leaf clover Trifolium angustifolium is an annual legume native to central, southern and Eastern Europe, western Asia and North Africa. It has been introduced elsewhere and is valued for forage and pasture improvement. It has become an environmental weed in a few countries such as Australia, Japan and Chile but has not been reported as an aggressive invader. It is included in the IUCN Red List (Least Concern) for its value as a genetic resource for forage legumes.

The Barbary sheep or aoudad Ammotragus lervia is widely distributed in the mountains of the Sahara and North Africa. The 2000 IUCN Red List assessment of the Egyptian subspecies A. l. ornata categorized this taxon as Extinct in the Wild. We present new evidence, collected during 1997–2000, that this subspecies is extant in both the extreme south-east and south-west of Egypt, and reassess the status of captive aoudad in Egypt. We recommend that the category of A. l. ornata on the IUCN Red List be changed to Critically Endangered, that conservation of wild aoudad in Egypt be prioritized, and that the subspecific status of both the wild and captive stocks in Egypt be reassessed.

Abstract The giant otter Pteronura brasiliensis, categorized as Endangered on the IUCN Red List, was once widely distributed throughout South America. By the middle of the 20th century the giant otter had become locally extinct along the main rivers of the Orinoco basin. Although some populations seem to have recovered, the paucity of information available does not permit a full evaluation of the species' conservation status. The objective of this study was to estimate the abundance and density of the giant otter population along the Orinoco river in the municipality of Puerto Carreño, Vichada, Colombia, where there is important commercial and recreational fishing. Thirty-nine linear km were surveyed, repeatedly, with a total of 315 km of surveys. Population size was estimated by direct counts of individuals. All individuals detected were photographed and identified individually from their throat pelage patterns. In total, 30 otters were identified, giving a minimum density of 0.77 individuals per km, one of the highest reported for the species in Colombia. Given the high density in this well-developed area, our results highlight the importance of this population for the conservation of the species.

Illegal Killing

AbstractThe Endangered Indian pangolin Manis crassicaudata, a burrowing, armoured mammal, plays an important role in the food web by consuming insects and termites. In Pakistan the species’ range includes the 22,000 km2 Potohar Plateau, where it is under pressure from illegal hunting for its scales and requires conservation attention. We used a geographical information system to quantify the range of the Indian pangolin on the Plateau and to compare this with the range estimated in the IUCN Red List assessment of the species. We found that the species occupies c. 89% of the Plateau, in eight of the 10 protected areas, compared with the IUCN estimate of 71%, and we recorded the species at 40 locations on the Plateau outside the range predicted by the IUCN assessment. We collected data on the illegal capture and killing of the species, recording 412 individuals that had been killed at 48 locations between January 2011 and the end of April 2013. The highest number of killings was recorded in Chakwal District (n = 156, at 13 sites) followed by the Attock District (n = 149, at eight sites). Although the Indian pangolin's range on the Potohar Plateau is c. 18% larger than that estimated in the IUCN assessment, the species is under pressure from illegal killing and requires urgent conservation measures to save the small remaining population and avoid the extirpation of this vital insectivorous predator from the area.

Abstract The brown hairy dwarf porcupine Coendou vestitus is a poorly studied Andean species endemic to Colombia. Its current Red List category is contradictory: globally it is categorized as Data Deficient but in Colombia it is categorized as Vulnerable. This contradiction has limited the implementation of conservation programmes. We evaluate the level of rarity of the species and provide consolidated information for a new assessment of its Red List status. We reviewed literature, photographs, and voucher specimens in natural history collections. Using the confirmed records, we estimated the extent of occurrence (EOO) based on the minimum convex polygon and the area of occupancy (AOO) summing the area of grid squares occupied by the species. We found that C. vestitus is very rare, with a small range, low estimated population density, occurrence in only one habitat type and small body size. The species has an EOO of 3,323 km2 and an AOO of 24 km2, based on six confirmed localities, all on the western slopes of the Eastern Cordillera, in the central Andean region of Colombia. Based on the species' rarity, restricted distribution, and threats to its natural habitat, we recommend its categorization as Endangered on the IUCN Red List. This will help delineate research and conservation efforts for this porcupine, which has a highly restricted range and inhabits the threatened Andean forest.
