I’m assuming you’ll be doing some planting around the pond so, if you can, try a frog/toad house amongst the plants. Dig a hole a foot or so deep (doesn’t need to be huge) put some rocks and branches in there, with good gaps in between, maybe a few handfuls of leaves too. Mound that up to a few inches above soil level with some obvious front entry ways, and then cover the top and back of your mound with soil, leaving a way in at the front, Once you’ve got some planting around it, you’ll barely know it’s there, but the frogs will love you for giving them a summer hideaway and a winter home. 😊
