Some 57 per cent are concerned about the reported decline in the bee population.
Those aged 25-34 are the age group which came second with regards to making the most effort to conserve or promote wildlife.
According to a survey of 1,000 UK adults by garden and conservatory furniture retailer, Alfresia.co.uk, a third of Britons have invested in products that conserve and encourage minibeasts in their gardens and outdoor spaces in the past 12 months, such as bird feeders (32 per cent), bird nest boxes (29 per cent), and insect houses (16 per cent).
The top five most popular ways British adults found to encourage wildlife into their gardens were:
- avoiding use of pesticides (68 per cent)
- allowing grass to grow longer in certain areas (37 per cent)
- composting (26 per cent)
- creating rock gardens (21 per cent)
- planting specific flowers to encourage bees (17 per cent)
Some seven per cent keep chickens, while four per cent keep bees in their outdoor space.
Over half (56 per cent) leave food for birds, while 14 per cent monitor the types and species of bird that visit their gardens.
