Sad. The beach area is a good idea, as would be a log or plank angling out of the water. My friend took a plank and covered it in bark. It looks relatively natural, and has saved a couple of groundhogs so far.
I know other people put nearly invisible plastic netting just below the water surface so nothing can get in and sink.
How sad. We don't have praire dogs around here (New England). But it is important to have a shallow area in any pond go anything that goes in for a drink can get out.
We don't have much problem with things getting in or even around our ponds. The wildlife has the creek out back and the springs out front and I think they prefer hanging out there because they don't have to deal with the dogs as much.
Wow, i never thought about groundhogs drowning. We're forever getting birds that drown in our pond. I have put rocks there so maybe they cold get out when they fall in, but i still find two or three dead birds a summer.
Really? Are they nearsighted, or is it something else? And what area do hedgehogs normally live? You'd think it would have to be someplace away from water if they can't swim. And now that I think of it, how do they drink if they drown? I see a hedgehog project in my children's future.
