UPDATED: This is a January 2009 post. For more up to data discussion of the effects of the freeze and thaw see the latest posts.
In my entirely unrepresentative survey of whether the icing up of ponds led to frog deaths we are now on dead frog reports 3, no dead frogs 2.
What can we tell from this? Well, really nothing more than that frogs sometimes die under the ice, whereas other times they don’t.
To get an accurate result we’d need to choose beforehand a cross-section of ponds, or a cross-section of pond owners, and then go to look at whether frogs were seen dead or not. The main problem is that its much more likely that you’ll report seeing dead frogs than seeing nothing – even though seeing nothing is just as important (perhaps more so) than the sad loss of our favourite pond animals.
But as is so often the case, we don’t have the kind of information we would really like to understand our ponds.
If anyone else would like to feedback, I’d be really interested to hear from you, especially if your pond iced up and you saw nothing – (how about that for introducing a bias to the results!).
THE COMMENTS SO FAR including some from the Froglife website – don’t forget to visit them too.
Checked our pond this morning and can straight away see 4 dead frogs…. Not pleasent. Martin
On our shallow pond (12″ deep), which does contain frogs, there were no sightings of dead frogs after the ice cleared. Steve
I have a large pond and, probably due to the extended freeze, has a large number of dead frogs, newts and dragonfly larvae. There is no sign of trauma or disease, just lots of bodies which is sad. David
….so far no dead frogs have been sighted. Margaret, Boston, Lincs.
Anonymous said…I read this too late, I’ve been trying to keep airholes in my small pond, home to many frogs for several years but alas this wed 07.01.09 11.59am, and there are at least 3 large dead frogs floating on the second layer of ice, and others that look like small brown toads…
