Protected areas (PAs) help in strategies for maintaining biodiversity and inhibiting deforestation of the Amazon rainforest. However, there are few studies that evaluate effectiveness lands protected by states (or federation units). Our goal was to compare land use change over 35 years state-level PAs with another area protection, both Maranhão state, Brazil. We employed remote sensing techniqu...

Abstract Background Soil quality, which can be inferred using indicators that interact synergistically, is affected by land use types and agricultural management practices. This study assessed the status of soil quality under three adjacent uses (cultivated, grazing, fallow) in Kersa subwatershed (622 ha). samples were collected from surface (0–20 cm depth) identified with replications paramete...

Invasive tree removal from grazing lands using costly brush management practices is widely employed. However, wildfire-like natural events can also prevent the increasing trend of woody encroachment in at no cost, instead expensive prescribed burning. This study aims to estimate effects wildfire 2002 on trends during post-wildfire period (2003–20), as well recurrence interval a site United Stat...

The importance of plant species diversity on performance of livestock grazing temperate region pastures is summarized in this review. As livestock producers seek less capital-intensive production systems, emphasis is redirected toward low-input pasture systems that rely on complex species mixtures to produce forage. Increased plant species diversity has been linked to improvements in ecosystem ...

Objective: Empirical evidence on the potential of area exclosure in restoration severely degraded lands is crucially important. Thus, a study was conducted to examine influence age vegetation structure, diversity, and biomass carbon stock central dry lowland Ethiopia. Methods: Exclosures 5, 15, >20 years old, adjacent open grazing land were selected. Data collected using 20 × m sampling quad...
