Effects of Tree Shelters on Tree Seedling Microclimate and Seedling Chlorophyll Production: Two-Year Results

/in , , /by

Matured riparian forests buffer streams and rivers downslope from the effects of upslope land use by improving water quality and providing carbon sequestration. Riparian forests also protect land upstream by minimizing the impacts of flooding and high winds. Restoring riparian forests has long been considered an agricultural best management practice as large-scale agricultural use intensifies […]
