Steep sides

Evening gang. Ive got a fiberglass preformed pond with near vertical sides. I want to be able to add something in case a wild beastie falls in. Has anyone had this issue and overcome it with a ramp or similar? Thanks

 

a piece of the sturdy stuff not the sort for covering fruit bushes.

If you have hanging over the side and let a plant grow through or over it will (you soon wont see it) give the hedgehogs and other small animals a opportunity to climb out

 

Or you can use hessian in a similar way...
