Bumblebees
What are Bumblebees?
There areย 22 species of bumblebee that currently exist in the UK,ย although some are given multiple common namesย which can give the impression of there being many more.
Why are Bumblebees important to the Surrey Hills?
Bumblebees help to pollinateย a number ofย commercial cropsย and many wildย plants rely on their pollinating activities, so theyโreย hugely importantย contributors towardsย maintaining biodiversity.
The condition ofย bumblebeeย habitatย and successful breedingย is threatened by:
- Management regimes that reduce the availabilityย and diversityย of flowering plants and shrubs
- Management regimes that reduce the availability of suitable nesting habitat.
- Disease
What habitat do Bumblebees like?
Pasture
Permanent pastureย and rough grazingย (hills,ย heathย and moorland)ย accounts for about 58%ย of the total utilised agriculturalย area in Englandย of 17.36 million hectares. This rises toย nearlyย 65% ifย temporary grassland (under 5 years old)ย isย included.ย This figure will includeย specific grassland types such as chalk grassland, dry acid grasslandย and floodplain grazing marshย but the majorityย will be agriculturallyย improvedย pastures thatย support the livestock sector.
True bumblebeesย have a queen whoย emerges from hibernation having mated the previous summer. After replenishing her own body reserves, sheย immediately sets about forming a new colony.ย The firstย batch to be rearedย isย female workersย whose role it is to provide foodย and care for the new colony. Males andย new queensย appear later in the season withย the whole colonyย including the old queenย ultimately dyingย that season and only the new queens having the possibilityย of surviving into the following year.
What can be done to benefit Bumblebees?
Good management and habitat creation opportunities for bumblebees include:
- The encouragement or creation of flower-rich meadows and field margins
- Leaving existing grass margins uncut until well into the autumn
- The creation of pollen and nectar plots which are managed to provide the longest possible flowering period
- Leaving uncut margins around grass fields and legume crops such as red clover andย lucerne
- Being aware of where bumblebees might nest and causing as little disturbance as possible to that area
