Make this and everyone will want to peer under it!

I love those things you can do in the garden to help wildlife that you might never have thought of and yet turn out to be really simple and fun.

And here's one of them. It's a brilliant way to help reptiles thermoregulate...

Or to put it another way, it's something to help your wildlife can warm up!

The best materials to use for your Wildlife Sunbed are called Onduline (above) or Coroline - they're the black, corrugated sheets you'll have seen on many a shed roof. You can get them from any big DIY store and really the only issue is that it normally comes in a 2m x 1m sheet; that's certainly too big to go in my car, so you may need to get it delivered.

I then cut a sheet in half, using a Stanley knife rather than a saw because otherwise the bitumen surface will clog your saw blades.

Punch a couple of holes in one side and attach a bit of rope and that will give you a simple handle to lift it gently up with. I advise you only look once a week so that any residents don't get scared off.

Then just lay it on the ground in a sunny, quiet position in the garden, maybe near longer grass or a log pile or compost heap.

Slow-worms love to shelter beneath them where they are dry, warm and safe, with lots of lovely tunnels to wriggle under.

And it's not only reptiles; you might find nests of sweet Field Voles or Bank Voles or all manner of fascinating creepy crawlies.

Let me show you what were under mine this week:

A millipede

An ant nest (notice how it is the shape of a corrugation)

The nest of a Short-tailed Field Vole (again the shape of a corrugation)

And some young Field Voles!

Have a go and let us know how you get on - we think you'll be amazed what turns up!
