Understanding of the impact of the types of livestock on the steppe training systems
Abstract
B. Djelloul
The steppe route in Algeria know a significant degradation due to human and animal pressure. This degradation occurs at the level of the reduction of vegetation cover and the disappearance of pastoral species, which affects the productivity of pastoral systems and as a result, worsening the level of poverty of the rural populations. The results obtained show that the pastoral plantation has a positive impact through increased both quantitative than qualitative (floristic wealth, global recovery, phytomass and pastoral productivity) courses developed by report to others. The floristic study highlights the floristic diversity with 51 species combination The floral study underlines the floral diversity with 51 sorts species of long-lived 17 and short-lived 34) led inferred by the plantation of Atriplex canescens. From the biodiversity point of view, notes the rise of thorny species course undeveloped after the eradication of the palatable species. Quantitative when it showed a gradual change in the collection at the level of the courses laid out resulting in a significant biomass of the order of 720 kg MS/ha and 122 UF/ha of which to answer the food needs for the livestock and to decrease the overload on the vegetation.
