3. What can we do to improve pollinator diversity and abundance in urban areas?

Urban areas have the potential to support large numbers of insect pollinators, however many cultivated plants do not provide suitable forage for them.

In recent years, sowing seed mixes containing beneficial flowers for insect pollinators has become increasingly popular in urban areas across the UK. For example, in Gloucester and Stroud the Bee Guardian Foundation are working in partnership with local councils to convert green areas, such as road verges and parks, into bee-friendly habitat. In Gloucester the project has replaced 10,000 m2 of bedding plants with perennial herbaceous species and created wildflower meadows.

Places with similar projects include Brighton, London, Warrington, York and Leeds. At the London 2012 Olympic site more than 10 hectares of flower meadows were sown, creating the largest ever man-made flower meadows. These practices increase the provision of foraging resources for bees and other pollinating insects in urban areas.

The replacement of traditionally planted areas with flower meadows also has the potential to be beneficial economically as well as for insect pollinators. It has been estimated that the replacement of winter bulbs with wildflowers has helped save Gloucester City Council money. Hence changing planting regimes to incorporate pollinator-friendly flowers can provide a visually pleasing floral display and also be economically viable.

In the third stage of the project we are adding large flower meadows containing nectar- and pollen-rich plant species to areas of amenity grassland in Bristol, Reading, Leeds and Edinburgh. In partnership with local councils, meadows are being planted in public parks, school playing fields, university grounds and road verges. This research will enable us to investigate if planting flower meadows in urban areas can improve conditions for pollinators in urban areas. 

To find out more information and discover your local meadow please see our flower meadows pages.

This phase of the project is being carried out in collaboration with Bristol City Council, Reading Borough Council, Leeds City Council and the City of Edinburgh Council.

Flower mixes

We are planting two types of flower mix:

Perennial
A perennial mix containing native plant species
Annual
An annual mix containing both native and non-native plant species

These two flower mixes have been chosen as they contain plant species high in pollen and nectar and provide forage for insects from early until late in the flowering season. Moreover, the mixes are designed to look attractive.

Timescale

In 2012 and 2013 we are installing 60 flower meadows across the country (15 each in Bristol, Reading, Leeds and Edinburgh).

Meadows sown with a perennial flower mix will be sown in 2012 and be in full bloom in 2013.

Meadows sown with an annual flower mix will flower in 2012 and be re-sown to flower again in 2013.

We will sample all meadows in 2013 to investigate whether the addition of floral resources rich in pollen and nectar is beneficial for urban pollinator populations.
