| 摘要： | Blowing and drifting snow adversely affect winter driving conditions and road infrastructure in Minnesota, often requiring removal methods costly to the state and environment. Living snow fences (LSFs)—rows of trees, shrubs, grasses, or standing corn installed on fields upwind of roadways—are economically viable solutions for controlling drifting snow in agricultural areas. Despite incentives and financial assistance by state and federal agencies, farmer adoption of LSFs is low, in part due to concerns about removing cropland from production. Of recent interest in Minnesota is the use of shrub-willows (Salix spp.) for LSFs, as they have been successfully implemented for LSFs in other states and are researched increasingly as a marketable biomass product for bioenergy production. To evaluate the potential of willow LSFs for multiple benefits in Minnesota, we established studies in Waseca, Minnesota, 1) to test different designs of willow LSFs in their ability to trap snow, 2) to compare the growth of willow varieties to willows native to Minnesota and other species traditionally used in LSFs, and 3) to assess the costs of planting and establishing a willow snow fence and the viability of biomass harvest. |
