Other posters have mentioned paving gardens and round 'ere, many front gardens are just that: paved or concrete. For cars. That is becoming more widespread and contributing to flooding in susceptible areas.
I hate seeing plastic grass too and there are a few front gardens locally which have installed it. Why?? No, don't answer!
Our garden is a mess at the moment because I've not been able to do much lately (recovering fracture). We back onto an area of woodland so the bottom of the garden has been turned into a woodland garden. DH made a narrow winding path through it using recycled bricks and I'm planting it up with mainly woodland or shade loving plants which attract wildlife. The pond is being re-dug (became leaky, overgrown and full of bindweed and bramble) and the small herb patch also contains blackcurrants and thornless blackberry. MIL isn't keen on it as it often looks uncontrolled and she likes things neat and structured, whereas we like a garden with a bit of mystery.
Even so, there are fewer insects around than there used to be and we don't get sparrows any more and haven't for years. We have bird feeders and blackbirds, nuthatches, chaffinches, robins, varieties of tits, wrens and thrushes visit, together with the larger ones and those darned parakeets!
Years ago Sarah Raven fronted a TV programme about planting for wildlife and I felt really excited by it. She tried to persuade a couple of councils to use wildlife-friendly plantings as a trial but years later, how successful has she been in converting councils to follow suit?
