“…Gebremedhin and Yirga (), who studied the presence of Soemmerring's gazelle only in the grassland habitat, have reported that average (from dry and wet seasons) population size of the species was 458 animals. Comparison of their result with the estimated 996 animals (average of the two seasons; see Table ) for the grassland habitat in the present study shows that population size of the species has been increased in the last decade.…”

“…Historically, the species was abundant and widespread in the Horn of Africa. However, it has been disappeared from several areas of its former ranges in the Horn (Gebremedhin & Yirga, ; IUCN, ). Thouless () and Jacobs and Schloeder () have reported that poaching and habitat degradation through cultivation and livestock overgrazing are the major causes of the decline in population and distribution range of the species.…”

“…In Ethiopia, the distribution of Soemmerring's gazelle encompasses the northeastern, eastern and southeastern lowlands of the country where they were previously described as locally common (Thouless, ; Yalden, Largen, Kock, & Hillman, ). However, both population and distribution range sizes of Soemmerring's gazelle in the country have been shown great decline, with viable populations of the species persisting only in some areas, such as the Alledeghi Wildlife Reserve (AWR) and the adjacent Afdem‐Gewane Hunting Area (Gebremedhin & Yirga, ; Jacobs & Schloeder, ). Thus, having better understanding on the spatio‐temporal population status of the species in such stronghold areas is important to track population changes, examine causes of the changes and take management measures.…”

“…Recognising the importance of the area for wildlife conservation, the Ethiopian Wildlife Conservation Authority has currently proposed to upgrade its protection status from reserve to a “National Park” (Wami & Mekonnen, ). However, AWR is also used for communal livestock grazing land local communities, particularly during dry season (Gebremedhin & Yirga, ; Kebede, ; Tadesse, ). This unregulated livestock encroachments has caused habitat degradation and transformation mainly due to rapid expansion of alien invasive species, particularly Prosopis juliflora (Kebede, ; Tadesse, ).…”

“…Consequently, and in the face of changing environment due to global warming and anthropogenic activities, information on seasonal population status and habitat use of conservation concern species, such as the Soemmerring's Gazelle, is required for formulating management and conservation strategies. So far, to our knowledge, the only ecological study on Soemmerring's gazelle in the AWR has been that conducted by Gebremedhin and Yirga (), which itself is incomplete as it encompasses only the grassland habitat. The specific objectives of this study were therefore to determine population status (current population size, age/sex structure and group size) and habitat preference of Soemmerring's gazelle in the AWR and how these parameters might vary between seasons.…”

This study was undertaken to determine the current population size, structure and habitat preference of Soemmerring's gazelle [Nanger soemmerringii (Cretzschmar 1828)] in the Alledeghi Wildlife Reserve, NE Ethiopia. Animals were counted, both during dry and wet seasons, along 12 line transects each in three habitat types (grassland, tree‐scattered grassland and bushland) in 2015/16. Habitat type had nonsignificant effect on mean population density of Soemmerring's gazelle, but wet season mean density was significantly higher than dry season mean density. Estimated weighted mean (±95% CI) population density of the species in the reserve was 1.90 (±0.17) and 5.99 (±0.370) individuals/km2 during the dry and wet seasons, respectively. Total population size of the species in the Alledeghi Wildlife Reserve was estimated at 826 ± 77 and 2,562 ± 158 individuals during the dry and wet seasons, respectively. Over half of the total population of Soemmerring's gazelle was represented by adult females during both seasons. Seasonal habitat preference of Soemmerring's gazelle was statistically significant, with greater preference for grassland habitat during wet season and for bushland habitat during dry season. In conclusion, this study has provided valuable data that will be used as a baseline for future population monitoring.

The status and habitat selection of the three species of gazelle indigenous to Eritrea, i.e., Nanger soemmerringii, Gazella dorcas and Eudorcas tilonura, are not well known. In this study, we analyzed the present distribution of the three species in the country in order to identify preferred habitats and assess the effect of human disturbance (land use for agricultural purposes and livestock) on species occurrence. These data represent baseline information for evidence-based strategies for conservation of the three species in Eritrea. Presence/absence data of the three species in each of the 67 administrative subregions (Sub Zoba) composing the country were collected using direct (field surveys) and indirect methods (questionnaires). For each sampling unit, we collected fifteen environmental variables, of which three are associated with climatic features, eight with vegetation structure and four with human disturbance (human-related land use and livestock). The occurrence probability of each species was modeled through Generalized Linear Models (GLM). The analyses showed that Dorcas gazelle occurred more frequently in warmer conditions and in a wide range of natural vegetation types. Heuglin’s gazelle occurred in warmer regions with higher seasonality in both temperature and precipitation with a preference for closed woody and open grassland areas. In the case of Soemmerring’s gazelle, the GLM with climatic variables predicted a preference for warmer conditions but with lower seasonality of temperature and precipitation. The species also seemed to prefer arid and semi-arid open vegetation. Human disturbance is the variable with the strongest, negative, effect on the species occurrence. Indeed, the occurrence probability of each species decreased with increasing livestock density and agricultural land use. Most of these gazelle occurred in unprotected areas, thus the human-related activities are undoubtedly the most important threat for the three species of gazelle in Eritrea. Therefore, the establishment of protected areas that preserve the potential optimal habitats for gazelle and reduce the impact of livestock ranching are essential to ensure a future for these gazelle in Eritrea.
