Weather-centric Rangeland Revegetation Planning

Rehabilitation and restoration of rangelands impacted by invasions of annual weeds are challenging because climate and weather variability affects seed germination, survival and establishment of seedlings, annual weed dynamics, wildfire frequency, and soil stability. In this publication, USDA Agricultural Research Service, USGS, and university partners, discuss opportunities for enhancing revegetation using site-specific weather information from historical observations, seasonal climate forecasts, and climate-change projections. Incorporating climate and weather information into rangeland revegetation planning could reduce management uncertainty, improve understanding of the ecological processes driving succession, and increase the efficiency of rehabilitation and restoration efforts. For example, historical climate data can be used to interpret success or failure of past seedings by describing patterns of environmental variability subsequent to planting. Seasonal climate forecasts and climate-change projections could improve the cost efficiency of management treatments and help develop mitigation and adaptation strategies for long-term practices. Adopting new weather technology would require collaboration between land managers and modifications to current restoration practices.
