Nationwide survey on the barriers to converting turfgrass lawns to pollinator-friendly native wildflowers

Abstract

The abundance and diversity of insect pollinators around the world is declining and habitat loss is a leading cause. Turfgrass lawns cover a vast area in North America and provide a great opportunity for habitat restoration to native wildflowers by the general public. Efforts to encourage the public to replace lawns with wildflowers could be improved by a better understanding of the thoughts and opinions of the public about lawns. We conducted a nationwide online survey to understand what barriers are most important in preventing people from converting a 6 x 6 ft portion of turfgrass lawn to native wildflowers. We also collected data on a variety of demographic factors to see if those influence survey responses. Over 3200 people took survey across the US. We found that ‘Maintenance time’ and ‘Not knowing what to do’ were the most important barriers to creating wildflower habitat. Age was the most important demographic factor impacting results with young people significantly more likely to select multiple barriers in the survey. For example, people aged 18-34 were 4.3 times more likely to indicate ‘Maintenance cost’ would prevent them from creating a wildflower plot than those age 65 or older. Those who had already created a wildflower plot, or those who were members in a native plant or pollinator organization were less likely to select barriers across the board, except for external barriers related to homeowners associations, neighbors, and local governments. This shows that these are persistent concerns even for those that are otherwise keen to create wildflower habitat. Our results suggest that outreach promoting pollinator-friendly native plant gardens should focus on clear and simple methods, small plots that will not take too much time and less likely to provoke neighbors or authority figures.
