Abstract/Contents:"Lawns are ubiquitous in North American urban environments and constitute a simplified ecosystem with low plant biodiversity. Considering their spatial importance, these areas have a great potential for improving biodiversity, for example by increasing their attractiveness for pollinators. However, scientific data on the use of alternative groundcovers in established lawns is scarce. Thus, the goal of this project was to monitor the attraction for pollinators and the resilience of four different groundcover species (Fragaria virginiana Miller, Bellis perennis L., Trifolium repens L. and Thymus serpyllum L.) incorporated into existing lawns in Quebec City and Montreal (Canada). A total of nine experimental sites were established in June 2021. Data on plant survival, growth and flowering period was collected at 21-day intervals in 2021 and monthly in 2022. In order to evaluate pollinator diversity and abundance, sweep net samplings were performed. Our results showed that all four plants can be successfully introduced in already established lawns. F. virginiana and T. serpyllum had the highest survival rates; T. repens and T. serpyllum showed the highest cover and B. perennis consistently produced the largest number of flowers. However, this last species was also the most affected by drought and had the lowest survival rate of all groundcovers. All groundcover species were able to tolerate frequent (i.e. every 14 to 21-days) mowing at 8 cm height. Established lawns in all sites presented an already important floral diversity. While very little impact on the abundance and diversity of pollinators from the addition of groundcover species was observed, a total of 2,391 bees and hoverflies were captured in lawns. Results from this project will be helpful for homeowners, municipalities and sod growers wanting to improve lawn biodiversity and provide new food sources to pollinators."
