Floristic Distribution According to the Edaphic Parameters of a Steppe Zone, Case of Study: The Nature Reserve “El-Mergueb” M’sila, Algeria

Abstract

The natural site of El-Mergueb, is one of the specific steppe ecosystem, that occupies an area of 16,481 ha; it is among the particular ecosystems in Algeria and is unique in northern Africa. It is located in the geographical limit of the Tell Atlas and the Saharan Atlas. It is at an altitude of 550 to 800 m, with a typically arid climate. The faunistic and floristic richness, quite specifically, contains species protected and classified in the IUCN: Chlamydotis and Gazella, as well as an autochthonous plant diversity: Stipa, Pistacia and Ziziphus. This study is based on the analysis of the vegetation by characterizing the associated soil type through the monitoring of the Eco-pedological relation during two seasons in three years: 2015−2016−2017. Nine soil profiles with a collection of twenty-one samples for each station of experimentation were collected. The results thus obtained showed that the content of the parameters analyzed is between low and average of the three stations. The average of the floristic analysis of the study area made it possible to define 34 botanical families spread over 69 botanical genus and 275 species. The analysis and the description of a natural space is important to establish a typology which is that is the basis for the development of management plans to conserve this category of protected areas. The FAC (Factorial Analysis of Correspondence) is relative to the individualization and the typology for three sequences, which corresponds to the groups (A), (B) and (C) also for the places in arid climate variants with very cold winters.

Rangeland Biodiversity and Climate Variability: Supporting the Need for Flexible Grazing Management

“…All species diversity indices (N 0 , N 1 , N 2 , and E 20 ) varied significantly with yearly climatic conditions, with higher values in the rainy year. Several recent studies showed that rainfall is a key driver of rangeland structure and function in arid areas [13,50,51]. However, exceptional highly favorable years can greatly change the diversity of arid rangelands.…”

New Investigation and Challenge for Spatiotemporal Drought Monitoring Using Bottom-Up Precipitation Dataset (SM2RAIN-ASCAT) and NDVI in Moroccan Arid and Semi-Arid Rangelands

“…Th e low quantity of organic matter in the soils and other mineral elements under a total limestone level dominate majority of the study stations and along with decrease in rainfall, these form the major causes of disruption of growth and development of plants. Also, inside this type of ecosystem, plants can resist to develop with a minimum of climatic conditions and edaphic cover (Adjabi et al, 2019).…”

Biogeography, inventory and new data on reptiles of M’sila region, Algeria

“…Its wettest month is September with an average rainfall of 25.6 mm, while July is the least rainy month with an average rainfall of 3.75 mm. January is the coldest month, with an average minimum temperature of 8.41°C; however, July is the hottest month, with an average maximum temperature of 31.11°C (Adjabi et al 2019).…”
