The Sierra de Guadarrama has a high richness of amphibian species.

Juvenil de sapo parteroThe amphibian inventory of the National Park and its Peripheral Protection Zone is made up of 15 species, of which 5 are Iberian endemism. Several studies on the areas of interest for the conservation of amphibians in the Iberian peninsula, have pointed out the Sierra de Guadarrama importance, and particularly the Peñalara Massif, in a number of species preservation.

This environment has a considerable diversity of species. Only in the Peñalara Massif wetlands, included in the RAMSAR list, there are usually nine species: the Common salamander (Salamandra salamandra), the Marbled triton (Triturus marmoratus), the introduced Alpine newt (Mesotriton alpestris), the Common frog (Hylo molleri), the Common toad (Bufo spinosus), the Natterjack toad (Epidalea calamita), the Common midwife toad (Alytes obstetricans) and the European tree frog (Hyla molleri). Some Iberian painted toad (Discoglossus galganoi) samples have also been detected.

It should also be noted that in the National Park live populations of species standing at the upper limit of their altitudinal range (Hyla molleri, Pelophylax perezi, Discoglossus galganoi and Triturus marmoratus). Therefore, the Park can be considered one of the most important European mountain areas in terms of its amphibian fauna. In fact, the number of species found here is greater than the total number of species known in some European countries (England, Ireland), and exceeds the other Iberian mountain systems.

The last samples taken in the National Park have revealed that the mottled newt, the common toad, the runner toad, and the frog of San Antonio, have experienced a decline in number compared to previous years. In contrast, the common frog and the Iberian frog have increased their abundance. There has also been a considerable expansion of the Alpine newt, a non-native specie from the center of the peninsula, which can be regularly observed in some Peñalara Massif wetlands.

Down below you will find a brief description of the most National Park representative amphibians:
