|
Since 2008 a study about the herpetofauna populations from the “Parque Regional en torno a los ejes de los cursos bajos de los ríos Manzanares y Jarama” has been developed by the Comunidad of Madrid. An inventory was performed, finding eight amphibian species and 19 reptile species, including three species of alien turtles. Also, a long term monitoring scheme has been designed and it´s currently running. 29 water points have been identified in the catalogue of priority habitats for amphibians. 42% were asociated to woodlands on gypsum substratum, 18% to gallery forest habitats and 17% to old quarries. Most of the water points are ponds (42%), streams (18%) and flooded areas (17%). Most correspond to lentic habitats (72%) on natural substrates (93%). Temporal (49%) and ephemeral (17%) water points are the most used by amphibians. Permanent water points, that are very common in the area, are avoided, probably due to the presence of alien species. Four our more species were detected only in 17% of the aquatic mediums. Regarding the presence of Emys orbicularis in the Regional Park, there´s a fossil register (Jiménez, E. 1978), that should confirm that natural origin of this population, in coincidence with the regional patchy distribution of this species. Between 2009 and 2012 26 individuals of E. orbicularis were captured. No juvenile was captured during monitoring. Gravid females were indeed captured, but we found no signs of successful reproduction. A eradication campaing of alien turtles is currently running, and also a complementary program of translocation of Mauremys leprosa individuals in order to decrease the pressure on the endangered population of European pond turtle.
