ah brilliant! We've been "supporting" some tadpoles in the garden this year, seeing them grow from frogspawn into little froglets is amazing - we've been making sure we have the best environment possible for them - the froglets can roam where they want but have cover when they need it too. Incredible how fast the transformation is as soon as they grow their back legs.
out of a large deposit of frogspawn only 5 will become adult frogs- the mortality rate is very high- the tiny tadpoles are food for other creatures like newts and birds- and the froglets are also easily swooped on if they have no cover when leaving the pond. Trouble is added to that is the fact that ponds are disappearing all over the country- they are being filled in for housing development or people are no longer wanting their garden pond and having that filled in too. One expert said that if the decline in numbers continues they'll to rename the Common Frog the Less Common Frog! We hope ours will be ok- done our best to provide cover for both the mini-pond and the surrounding area, should be a plentiful supply of food around too from what I've seen. It's very easy to create a mini-pond- you don't even have to dig out an area, you can do what we did and use a large gardening tray- maybe early next year I'll explain how you can do it- you do need to look at the garden itself and see if there's enough cover but is not a big issue to sort out. We've still got a few tadpoles with tails but hopefully they'll be little froglets soon!
