Thursday May 26th was a day full of (re)encounters. Upon our arrival to the gravel pit we found the commission of the contest, who was gathered that morning, and our colleague Rocío de Torre having a picnic around lunchtime. However, the most exciting thing was to meet with old friends: young natterjack toads (Epidalea calamita), who last week were still larvae, that day were running across the wetter areas. We also saw again spadefoot toad tadpoles (Pelobates cultripes) and common parsley frog (Pelodytes punctatus). At the end of the day we had a completely unexpected and certainly unforgettable encounter: a single larva of marbled newt (Triturus marmoratus) appeared in our bait dip net. Eventually far from negligible was coming across with an adult spadefoot toad on a road outside the exploitation. It is really impressive how peaceful they are!

During the time we wandered the roads of the gravel pit, we never stopped hearing common frogs’ singings (Pelophylax perezi, always in the vicinity of the permanent ponds. We also heard them outside the gravel pit facilities. They seem to have no problem to colonize the most unfavourable habitats for amphibians.

The next morning was dedicated to finish characterizing habitats of other water bodies. After lunch, we took our way back to Madrid, with so many data and experiences to be processed.
