Those of us of a certain age remember distant childhood times when everyone so it seemed had access to a local pond with abundant tadpole populations. Such a rain-replenished pond was dug perhaps 10 years ago in Perivale Park. For a fair few of these subsequent years tadpoles were indeed seen. However the pond was fairly shallow and had often dried out just before the tadpoles were due to leave it as frogs. Now its been enlarged!
All that is now needed is winter rains, and hopefully ponds large enough to hold water until well into next August or beyond.
