City is committed to mitigating our impacts on biodiversity by incorporating the principles of conservation into estate planning and management, and by preserving and enhancing existing habitats where possible on campus.
A biodiversity baseline survey was conducted in 2012, which led to the development of a new Biodiversity Strategy in 2013.
There are already a number of initiatives underway at City which are contributing to biodiversity efforts, including:
- A vegetable garden for staff and student volunteers to tend and enjoy;
- Green space in the College Courtyard area, which includes a green wall and green roof, plus seating for a relaxing environment;
- Drysdale Garden which includes additional green space and seating area for staff and students;
- A beehive on the roof of the Library.
For more information or to get involved in the gardening or beekeeping at City, please email Sustainable City.
Beekeeping at City
The roof of University building now houses City’s beehives. City will have its own vegetable garden soon, and already has one green roof (on top of the performance theatre in College Building) and a green wall (in the College Courtyard).
The beehives will help to raise awareness with City staff, students and the local community about the importance of protecting our biodiversity and bees in particular.
The staff and student Bee Team are responsible for looking after the hives and harvesting the honey (around 10-20 kg a year).
If you want to learn how to work with bees and are interested in joining the Bee Team, please email Sustainable City.
The beehives are supervised by professional beekeeper Dr Luke Dixon of Urban and Community Beekeeping, who is an expert in rooftop and urban beekeeping and a member of the British Beekeepers Association.
Dr Dixon provides training for staff and students so they can learn how to manage a hive.
- In the UK alone, bees contribute £200m a year to the economy through pollination. In all, bees play a crucial role in pollinating some 90 commercial crops worldwide.
- The British Beekeepers Association estimates that if people were to take over the job of pollination from bees in the UK, it would require a workforce of 30 million.
A bit about bees
- In the UK there are approximately 44,000 beekeepers looking after around 240,000 hives.
- A hive can contain up to 70,000 bees in midsummer. There is one queen, 250 drones, 20,000 female foragers, 30,000 female house-bees, 5,000 to 7,000 eggs, 7,000-11,000 larvae being fed and 16,000 to 24,000 larvae developing into adults in sealed cells.
- The queen makes a mating flight during her early life during which she stores the sperm from up to 20 drones. Drones that mate with her die in the act. She can store the sperm for up to five years.
- Bees are busy outside of the hive from the onset of warm spring weather until the beginning of autumn. While flowers are in bloom they will collect nectar and make it into honey which they store in the hive to live on over the winter months.
- A worker honeybee in summer lives only six to eight weeks from the time she hatches as an adult bee. Before that, it takes just three weeks for her to develop from an egg.
- During the winter the bees rarely leave the hive but cluster together to keep warm. Winter bees live for six months and will occasionally go outside to defecate in order to keep the hive clean.
