Rangeland vegetation dynamics can be affected by various natural and unnatural factors over time. The purpose of this study was to investigate the dynamics of vegetation under the climatic conditions and soil properties. Accordingly, data collection for evaluating vegetation dynamics in rangeland ecosystems of Ardabil province was conducted at three research sites including Moqan winter rangela...

Reliable measures of biomass, species composition, nitrogen status, and nutritive value provide important indicators the status pastures rangelands, allowing managers to make informed decisions. Traditional methods sample collection necessitate significant investments in time labor. Proximal sensing technologies have potential collect more data with a smaller investment However, protocols for c...
