Vegetation Response To Grazing Pressure In The Puna Flat, Nw Argentina, M. Quiroga Mendiola, A. Tálamo
Vegetation Response To Grazing Pressure In The Puna Flat, Nw Argentina, M. Quiroga Mendiola, A. Tálamo
IGC Proceedings (1977-2023)
Puna grasslands are located at a high‐altitude flat plateau in the Northwest of Argentina. It is an arid territory (100 to 300 mm rainfall/year) at 3,000 to 4,000 m a.s.l. The vegetation is scarce, where Andean pastoralist communities produce meat and wool, specialized in llama (Lama glama) and sheep‐breeding, although they do breed multi‐species herds that may also include goats and cattle. There are erosion processes in the Puna, where shepherds and their animals could be synergetic factors with natural very hard climatic conditions. In this work we assess the effect of ovine and lama grazing on the …
Grass Species Density And Biomass Of South African Communal Property Association Farms Differing In Soil Properties, K. E. Ravhuhali, B. Moyo
Grass Species Density And Biomass Of South African Communal Property Association Farms Differing In Soil Properties, K. E. Ravhuhali, B. Moyo
IGC Proceedings (1977-2023)
Attempts to monitor and mitigate rangeland deterioration in Communal Property Associations projects require some understanding of the knowledge of species composition and distribution. The study was conducted to compare the herbaceous in three selected CPAs projects (Mashung Matlala - Sandy loam, Mawela - clay loam, and Bela-Bela - clay) in South Africa. Mawela and Mashung Matlala CPAs were overgrazed. For species density, basal strike, and biomass, three transects (500m), which served as replicates, were established at two camps of each of the selected CPAs. Variation in herbaceous vegetation parameters was explored through SAS software. Clay soil type had better (P …
