Disturbance, vegetation cover density, season and total nitrogen are significant factors that control the dynamics and management interventions to maintain the forest health of dry Afromontane forests.Ībubacker M, Visvanathan M, Srinivasan S (2014) Impact of pesticides on AMF spore population and diversity in banana (Musa spp.). The SD was significantly higher ( p 0.05) except for total nitrogen. Vegetation cover density strongly affected SD and RC. Glomus was the dominant genus in the rhizosphere of all species. Spore density ranged from 50 to 4467 spores/100 g soil, and all species were colonized by AMF within a range of 4–95%. A 100 g sample of rhizosphere soil from moisture-free composite soil was used to determine spore density. Each plot (160 × 40 m 2) has two management practices (fenced and unfenced plots) of area. AMF RC and SD in the rhizosphere of five dominant woody species, Juniperus procera, Olea europaea, Maytenus arbutifolia, Carissa spinarum and Dodonaea angustifolia growing in Desa’a forest were studied during the rainy and the dry seasons in three permanent study vegetation cover density plots (dense, medium, and poor). This study was aimed at determining how the seasonal, vegetation cover density, edaphic and anthropogenic factors affect AMF root colonization (RC) and spore density (SD) in Desa’a dry Afromontane forest. Arbuscular mycorrhiza fungi (AMF) are vital in the regeneration of vegetation in disturbed ecosystems due to their numerous ecological advantages and therefore are good indicators of soil and ecosystem health at large.
