I envy you. We tried a wildlife pond with a liner and it looked lovely. Within three months the water level kept going down, a worry because we had frogs and Newts in residents. What we didn't account for, was some wood mice that also became residential with our log store and decided to chew a hole in the pond liner, so out came the liner and we had to put a preformed pond in, to accomodate mice as well as frogs and newts :You've created a wonderful wildlife pond, a real pleasure to look at and I'm sure a real pleasure to sit by.
Wonderful pond - i’m In the process of making my own an wondered please where did you get your river bed pebbles from ? as they look great and really bring it to life , many thanks Michael
