Some of our non-natural ecosystem components have important roles to play, not only in hosting a relatively rich biodiversity compared to some of their natural/semi-natural counterparts, but also in the education of children. Most children in the UK live in urban environments surrounded by non-natural habitats and with limited opportunities to visit more distant semi-natural nature reserves, even if it occurred to them. If these children are going to grow up caring about the fauna and flora of Wales, they must be given the opportunity to engage with, learn about, and value the wildlife on their doorsteps. The future of the semi-natural habitats in Wales will depend on future generations learning to value them and the non-natural parks, gardens and brownfield sites in our towns and cities have a key role to play in this. Several of these important non-natural ecosystem components are described in the sections below.
