Bristol is buzzing, how the city is helping pollinators

There has been a substantial amount of press coverage recently on the plight of our pollinators. They are now less abundant and widespread than they were in the 1950s. A number of threats are responsible, including habitat loss, disease, extreme weather, climate change and pesticide use.

There is not one smoking gun among these threats, but rather the combination that has endangered some species in the UK. Loss of wild flower rich habitat (due to intensive agriculture, industrialisation and urbanisation) escalates the effect of disease, extreme weather, climate change and pesticide use. Without food or shelter, pollinators are more vulnerable.

Whilst visiting the University of Bristol Botanic Garden a few weeks ago, I noticed the abundance of pollinators busily visiting many different flowers from the orchid look-a-like flower of Impatiens tinctoria to the swathes of Rudbeckia sp. and Verbena bonariensis. This year saw the 6th year of the University of Bristol Botanic Gardens hosting the Bee and Pollination Festival in September. The Community Ecology Group from Bristol's School of Biological Sciences was exhibiting and promoting their research as well as the exciting Get Bristol Buzzing Initiative.

To find out more about pollinator research at the University, I met up with Dr Katherine Baldock, a NERC Knowledge Exchange Fellow from the School of Biological Sciences and the Cabot Institute, to discuss the group’s work.

“Most people know that pollinators are important, but quite often don’t know what to do to help them, “ explained Katherine. “And this is where our research at the University comes into play”.

The aim of Katherine’s fellowship is to improve the value of the UK's urban areas for pollinators by working with various stakeholders, such as city councils, conservation practitioners and the landscape industry.


Translating science into solutions


Up until 2014, Katherine worked on the Urban Pollinators Project, which is researching insect pollinators and the plants they forage on in urban habitats.

Building upon research from this project and her current Fellowship, Katherine and her Bristol colleagues have contributed to the development of  a Greater Bristol Pollinator Strategy (2015-2020). The University research group has teamed up with Bristol City Council, the Avon Wildlife Trust, Bristol Friends of the Earth, Buglife, South Gloucestershire Council and the University of the West of England to implement this with the aim of protecting existing habitat and increasing pollinator habitat in the Greater Bristol area.

The group is also raising awareness of the importance of pollinators to a wide-ranging audience within the city and further afield. This is the first local pollinator strategy within the UK and follows closely in the wake of the Department for Environment, Food and Rural Affairs' National Pollinator Strategy launched in 2014. It will help to promote aspects of the national strategy relevant to urban areas and hopefully set a precedent for the development of other local pollinator strategies throughout the UK.

The local pollinator strategy outlines actions that will help fulfill the strategy aims, including:

  • formation of a Local Pollinator Forum intended to share knowledge and best practice,
  • establishment of a joined-up approach to pollinator conservation by linking projects through the ‘Get Bristol Buzzing’ Initiative,
  • working with the public in local areas to explain actions they can take as individuals. 

“Urban green spaces are important corridors for wildlife and help to provide linkages across the country”, explained Katherine. I envisaged a series of insect aerial motorways linking the whole of the UK, invisible threads connecting countryside, urban fringe and city centres.

The Get Bristol Buzzing Initiative is doing just that, as one of its strategic aims with the local pollinator strategy for 2016-2020, is to “Map pollinator habitat and identify target sites that allow habitat networks and stepping stones to be created to enable pollinators to move through urban areas”.

Katherine talked about how engaging the public at ground level was really important to Get Bristol Buzzing. The initiative is the pollinator component of My Wild City, a project whose vision is for people in Bristol to help transform spaces into a city-wide nature reserve. A number of interactive maps have been created that allow people to add what they have been doing in their area to help wildlife. The Get Buzzing Initiative will feed into these maps. Kath said,
‘The fact that you can add yourselves onto a map makes the Get Buzzing Initiative really visually appealing to people and much more personal.”
So, what can you do at home to help urban pollinators?

  • Plant for pollinators. Think about what plants you have in your garden. Could you change the planting or improve on it to make it more attractive to pollinators? Think about growing species that have nectar and pollen rich flowers and let your lawn grow longer to allow plants to flower. 
  • Avoid pesticides. Most gardeners like their plants to remain pest free but avoid the temptation to use pesticides and accept the fact that you will lose some plants to pests. Instead try to encourage wildlife that will devour those pests or cultivate plants that will deter pests.  
  • Provide habitat. As pollinators need a home, you can always make your own nest boxes if you want to give your pollinating visitors a helping hand by drilling holes in a log or by bundling up lengths of hollow sticks such as bamboo. Visit the Botanic Garden's bee hotel for inspiration!
‘Setting aside a wild bit of garden can help pollinators by providing food, but provides nesting sites too’, remarked Katherine.

Bristol Future’s magical places: Sustainability through the eyes of the community

“What is science? Why do we do it?”. I ask these questions to my students a lot, in fact, I spend a lot of time asking myself the same thing.

And of course, as much as philosophy of science has thankfully graced us with a lot of scholars, academics and researchers who have discussed, and even provided answers to these questions, sometimes, when you are buried under piles of papers, staring at your screen for hours and hours on end, it doesn’t feel very science-y, does it?

 As a child I always imagined the scientist constantly surrounded by super cool things like the towers around Nicola Tesla, or Cousteau being surrounded by all those underwater wonders. Reality though, as it often does, may significantly differ from your early life expectations. I should have guessed that Ts and Cs would apply… Because there is nothing magnificent about looking for that one bug in your code that made your entire run plot the earth inside out and upside down, at least not for me.

I know for myself, I…

The new carbon economy - transforming waste into a resource

As part of Green Great Britain Week, supported by BEIS, we are posting a series of blogs throughout the week highlighting what work is going on at the University of Bristol's Cabot Institute for the Environment to help provide up to date climate science, technology and solutions for government and industry.  We will also be highlighting some of the big sustainability actions happening across the University and local community in order to do our part to mitigate the negative effects of global warming. Today our blog will look at 'Technologies of the future: clean growth and innovation'.



On Monday 8 October 2018, the IPCC released a special report which calls upon world governments to enact policies which will limit global warming to 1.5°C compared with pre-industrial levels, failure to do so will drastically increase the probability of ecosystem collapses, extreme weather events and complete melting of Arctic sea ice. Success will require “rapid and far-reaching” actions in…

Will July’s heat become the new normal?

For the past month, Europe has experienced a significant heatwave, with both high temperatures and low levels of rainfall, especially in the North. Over this period, we’ve seen a rise in heat-related deaths in major cities, wildfires in Greece, Spain and Portugal, and a distinct ‘browning’ of the European landscape visible from space.

As we sit sweltering in our offices, the question on everyone’s lips seems to be “are we going to keep experiencing heatwaves like this as the climate changes?” or, to put it another way, “Is this heat the new norm?”

Leo Hickman, Ed Hawkins, and others, have spurred a great deal of social media interest with posts highlighting how climate events that are currently considered ‘extreme’, will at some point be called ‘typical’ as the climate evolves.
In January 2007, the BBC aired a special programme presented by Sir David Attenborough called "Climate Change - Britain Under Threat".

It included this imagined weather forecast for a "typical s…
