Urban Pollinators Project: Our last field season

We finished our final fieldwork season in September this year and despite the cold spring it was a successful season. In April we started to re-sample the urban habitats we sampled throughout 2012 and re-visited allotments, gardens, cemeteries, parks, road verges, local nature reserves, school playing fields and car parks in Bristol, Reading, Leeds and Edinburgh to look for pollinators visiting flowers.

Many pollinators, especially bumblebees, seemed to have been delayed by the cold spring weather and came out later than usual. The near-absence of worker bumblebees in May and early June was especially worrying. Solitary bees seemed to cope better with the unfavourable weather. In Reading we saw more solitary bees this spring than in the first two field seasons in 2011 and 2012. The hot and dry July and less hot but still quite dry August and September provided ideal conditions for butterflies and many other pollinators. Numbers of bumblebees quickly recovered and butterflies were abundant throughout summer.

As the success of our fieldwork depended on the goodwill of garden owners and other land owners and managers we would like to thank all garden owners in Bristol, Reading, Leeds and Edinburgh who volunteered their gardens  and all land owners and managers for giving us access to many of the sites we sampled.

From early June onwards we also started to sample project flower meadows sown in parks, on school playing fields, road verges and one site in a cemetery in Reading. The perennial meadows were established in early 2012 and flowered for the first time this year. The annual meadows were sown in April this year and started flowering at the end of June in southern sites and early July further North.

Our meadows not only attracted countless pollinators such as solitary bees, bumblebees, butterflies and hoverflies but also provided food and shelter for other wildlife such as beetles, bugs, damselflies, spiders and birds.

Here is how the Reading flower meadows looked like in July and the Leeds flower meadows in August. Also have a look at the best of the Bristol flower meadows.

Our winter tasks are to finish the data entry for all of the fieldwork this year, input insect identifications from the taxonomists at the National Museums of Wales in Cardiff, analyse the data and publish our findings. Please have a look at our website, Twitter accounts (Reading, Bristol, Leeds, Edinburgh) and visit our blog for updates and news from our project and for more information about pollinators in general.
