Invasive plants reduce the capacity of ecosystems to provide goods and services required by society, alter ecological processes, and can displace desirable species. They can reduce wildlife habitat quality, riparian area integrity, rangeland economic value, and enterprise net returns. The invasion process is regulated by characteristics of the invading plant and the community being invaded. The...

Soil characteristics and functions are critical determinants of rangeland systems and the ecosystem services that they provide. Rangeland soils are extremely diverse, but an emerging understanding is that paradigms developed in more mesic forest ecosystems may not be applicable. Vascular plants, biological soil crusts, and the soil microbial community are the three major functional groups of or...

We conducted a 5-year study on the impact of nutrients, depending on stream and season. grazing on stream-channel bare ground and erosion, and a © CSA 3-year study of cattle-trail erosion on intermittent stream channels draining grazed oak (Quercus)-woodland 450. Correlations of stocking with the cryptogamic soil watersheds. These studies were conducted on the San crust of a semi-arid rangeland...

Degradation characterized by depleted vegetation cover is a serious environmental problem in African rangelands. It poses threat to millions of pastoralists and agropastoralists who depend on livestock as source livelihood. Consequently, there has been growing global interest consolidate efforts restore degraded ecosystems. For example, the UN decade Ecosystem Restoration initiative aims at uni...

biological diversity and species richness have been declined throughout the world as a result of human activities. measuring species richness is important in rangeland conservation to evaluate the status and trends of native plant species, detecting non-native species invasion and monitoring rare species. however, heterogeneity in plant distribution makes inventories difficult. in this study tw...
