A UNIVERSITY ecologist has identified the dandelion as a key contributor to boosting the bee population in urban areas.
Dr Duncan Westbury, from the University of Worcester, is calling on the public to think twice before mowing over dandelions or spraying weed-killer, in an effort to stop the decline of bee populations.
With researchers taking measurements from more than two million flowers, Dr Westbury, Senior Lecturer in Ecology and Environmental Management, was part of the Urban Pollinators Project, a major study of wildflowers in four UK cities.
Focusing on understanding how to boost bee numbers in urban areas, the study revealed the importance of dandelions in helping bees, as this species was in the top five nectar producers.
He said: “It is evident that dandelions have a role to play early on in the year. Dandelions are particularly valuable in March and April because there are not many other flowers around at that time.
“Simple measures such as not cutting small areas in your garden, or the council not cutting the full width of road verges can provide opportunities for so called weed species to flourish and benefit bees.”
Dr Westbury said the Urban Pollinators project clearly demonstrated the value of establishing wildflower meadows in urban areas.
Results from the study could also help guide the development of seed mixes to ensure they include species that produce the most nectar and pollen throughout the year.
“We know that urban gardens are good for bees, but if residents continue to tarmac or pave their front gardens, or put down artificial turf, our urban parks and schools are going to be increasingly important for providing for bees,” he added.
