Large numbers of children in Britain are missing out on the natural world, a study from the RSPB suggests.
The three-year project found that only 21% of children aged 8-12 were "connected to nature".
Girls were much more likely than boys to be exposed to the great outdoors, while children in Wales had the lowest score across the UK.
The RSPB says that a perception among some adults that nature is dangerous or dirty could be holding children back.
There has been an increasing amount of research in recent years underlining the lack of contact and experience with nature among modern children.
