Vegetation characteristics, rangeland status and health determination of some natural rangelands

Turkish Journal of Forestry, 2018
This research was carried out in 2015 in order to determine vegetation characteristics, rangelands status and health of some natural rangelands. Studied rangelands are located in Diyarbakir province Cermik subprovince with average 950 meters altitude and 2-5% slope in Artuk, Agachan, Sarıbalta and Orenkur villages.

The collective application of shorebird tracking data to conservation

Conservation Biology, EarlyView.
Abstract Addressing urgent conservation issues, such as the drastic declines of North American migratory birds, requires creative, evidence‐based, efficient, and collaborative approaches. The abundance of over 50% of monitored North American shorebird populations has declined by over 50% since 1980. To address these declines, we developed a partnership

The relative productivity index: Mapping human impacts on rangeland vegetation productivity with quantile regression forests

Ecological Indicators
Rangeland degradation is a persistent decline in the productivity of vegetation that supports wild or domestic herbivores. However, rangelands often exhibit highly variable climates and dynamic, resilient vegetation, making it difficult to discriminate ...

Comprehensive framework for assessing and optimizing existing research networks

Conservation Biology, EarlyView.
Abstract Conservation, monitoring, and research networks, or collections of ecological research sites unified under a common mission of data collection or a research mission, are essential infrastructure for understanding large landscapes. However, most networks developed opportunistically over decades rather than through systematic design, creating ...

Centering geospatial data uncertainty and the potential for injustice in pastoralist rangeland conservation prioritization

Conservation Biology, EarlyView.
Abstract Procedural, distributional, recognitional, and epistemic justice aspects of conservation interventions are well documented in contexts where pastoralism is a key livelihood and way of life. Geospatial analyses and representations of wildlife conservation and restoration that are increasingly applied in pastoralist rangeland socioecological ...

The Piosphere Effects of Livestock Grazing on Rangeland Vegetation in Ahir Mountain of Kahramanmaras Region

Journal of Agricultural Sciences, 2017
Excessive grazing pressure on rangeland vegetation reduces the basal area value of vegetation and also changes the botanic composition. This study examined the piosphere effects of livestock grazing on rangeland vegetation based on distance from a ...

Seed pellets containing activated carbon increase emergence of native plant species used in dryland restoration following herbicide application

Restoration Ecology, EarlyView.
Abstract Introduction Over half of dryland ecosystems worldwide are degraded, making restoration a priority. Most dryland restoration efforts use seed‐based approaches, which often result in limited establishment of desirable species. The dual challenges of abiotic stressors and invasive species dominance are key barriers to native plant community ...
