We assessed connectivity in Aridos Sanz and its surroundings for Pelophylax perezi, Pelobates cultripes, Pelodytes punctatus and Triturus marmoratus, and we got that most generalist species have more connectivity, whereas specialist have more trouble to move in this landscape.

According to connectivity assessment, there are two set of measures involving connectivity improvements:

- A corridor that joins core water bodies in the gravel pit to the “Riberas del Duero y sus afluentes” SCI, following north-south direction. The corridor is formed by ponds, pond systems and water troughs.
- The improvement of habitat suitability in the existing water bodies of the gravel pit. Little efforts in (1) slope reduction, (2) creation of shallow areas and (3) construction of little sand heaps in existing water bodies, improve in a synergic manner the connectivity.

But...how could we do that? How much will cost? Take a look in our “Guide for integrated management of amphibians in gravel pits” available in https://goo.gl/shqu5v.

This guide is targeting gravel pit managers, able to make decisions in landscape configuration, and all workers interested in biodiversity conservation. It is focused in Áridos Sanz gravel pit case, but can be applied to many other quarries. It is already available in Spanish… any volunteer for the translation into English or other languages? :P
