After going through extremely complicated dirt roads and jumping some fences, we got to the first pond. Due to its characteristics, this location included in the degraded holm oak forest made us feel optimistic. We could not observe adult individuals, but found lots of larvae of common spadefoot toad (Pelobates cultripes) and some of common parsley frog (Pelodytes punctatus). The following locations did not provide any new information. Our bait dip net only drawn American red swamp crayfish (Procambarus clarkii) in various stages of development. We could only see tadpoles again at the exploitation heading, this time of natterjack toad (epidalea calamita).
By nightfall, both around and inside the gravel pit, we found some adults of natterjack toad. They appeared on the roads, among the marginal vegetation and mainly in the puddles generated by vehicles. In addition, nearby to the railroad tracks, in a well-like structure, the same common frog (Pelophylax perezi) we saw on our previous visit was still trapped.
On Saturday, and after Gonzalo’s farewell the night before, we went to the gravel pit to characterize the habitats in which water bodies are included. In the late afternoon, after spending the day without seeing any amphibians, under the shade of the poplar trees’ plantation we found a flooded area full of natterjack toad tadpoles, a fact that put a sweet ending to our trip.
