Establishment of Wildflower Islands to Enhance Roadside Health, Ecological Value, and Aesthetics - Phase II

A previous study completed by the University of Nebraska-Lincoln (UNL) in collaboration with Nebraska Department of Transportation (NDOT) has shown that wildflowers compose less than 10% of the botanical composition of highway roadsides 10 years following seeding. More recently in 2016, UNL/NDOT launched a new project to test the use of wildflower islands as a means of increasing the establishment and persistence of wildflowers on roadsides (phase I). These islands varied in size and consisted of segregated stands of diverse mixtures of wildflowers within grass-dominated roadsides. From this two-year study, the research team demonstrated that islands promoted higher bee abundance and richness than conventionally seeded plots following current NDOT practices.
