Eight amphibian species have returned to Cap de Creus, thanks to significant rainfall this spring. This recovery is crucial for biodiversity in the region.
After a prolonged period of drought, Cap de Creus has witnessed a remarkable resurgence of its amphibian population, with all eight documented species now thriving in the park. The revitalization can be attributed to substantial rainfall this spring, which replenished vital water sources necessary for these creatures’ survival.
The Societat Catalana d’Herpetologia, responsible for monitoring amphibian populations across various sites in Catalonia, has confirmed the presence of both larvae and adult specimens during their latest census. Among the species identified are the green frog, painted frog, common toad, and the green salamander. Field technician Marina Torrellas expressed her astonishment at finding all species present: “We were surprised to find them all,” she stated.
This positive trend follows a concerted effort last year when approximately 3,000 liters of regenerated water were introduced into a historic pond at Mas Ventós by forest fire prevention teams. This initiative aimed to support amphibian reproduction in an area that had been completely dry due to severe drought conditions. The recent rains have further enhanced these efforts.
The collaboration between the Societat Catalana d’Herpetologia and Cap de Creus aims not only to document current populations but also to establish long-term trends through statistical analysis. Historical data indicates that certain areas within the park had previously supported diverse amphibian life before succumbing to dryness.
As part of their ongoing project, volunteers and professionals conduct regular surveys across various sectors of Cap de Creus, including Roses and Cadaqués. These nocturnal observations are crucial as many amphibians are more active during nighttime hours when they congregate around water bodies.
The findings from recent censuses indicate that after years of extreme dryness, several previously desiccated sites are now rehydrated. Júlia Valera from the Societat emphasized that such conditions favor reproduction since amphibians require moist environments for their eggs and larvae.
This year’s initial census following spring rains suggests a stable trend in amphibian populations; however, experts remain cautious about future outcomes as summer heat sets in. Valera noted that it will be essential to monitor how these temperatures affect habitats moving into autumn.
The importance of conducting thorough follow-ups within protected areas like Cap de Creus cannot be overstated. It allows researchers to compare managed versus unmanaged zones effectively while highlighting the ecological significance of this region for biodiversity conservation.
For those interested in observing these fascinating creatures or supporting conservation efforts, visiting Cap de Creus offers numerous opportunities for exploration along its trails and water bodies throughout the summer months.
