Morocco has one of the highest rates (28.6%) of amphibian endemism among countries bordering the Mediterranean Sea and, while large areas of Morocco are crucial for conserving amphibian biodiversity, some areas are not afforded legal protection. We examine biodiversity, identify immediate anthropogenic threats, dis- cuss critical habitat for the conservation of amphibian diversity and the role of currently protected areas in meet- ing conservation goals within Morocco, Western Sahara included. The study area harbours 14 amphibian species, eight of which are assigned to the categories of Endangered (Pelobates varaldii), Vulnerable (Salamandra algira, Amietophrynus xeros, and Hoplobatrachus occipitalis) or Near Threatened (Pleurodeles waltl, Alytes maurus, Bufo spinosus, and Barbarophryne brongersmai) using IUCN criteria at the regional level of the study area. Habitat loss and degradation due to conversion of land for agriculture, urbanization, or industry are major threats, but infrastructure for tourism, freshwater pollution by chemicals, introduction of non-native species to aquatic ecosystems (Gambusia holbrooki), pathogens (Batrachochytrium dendrobatidis), road-kills, and natural disasters (drought), are also rapidly increasing threats. In addition, consequences from global warming must also be considered. The present Conservation Area Network (CAN) does not include distributional ranges of some amphibian species, and a more complete CAN in Atlantic and desert areas is suggested. The northwestern Atlantic, Rif-Middle Atlas, Central Atlantic, and Tiris regions should be considered priorities for conservation because of amphibian endemism and/or the existence of isolated amphibian populations.

Marruecos posee una de las tasas más elevadas de anfibios endémicos (28.6%) entre los países de la cuenca mediterránea y, a pesar de que exten- sas áreas de Marruecos son fundamentales para la conservación de la biodiversidad de anfibios, otras zonas no gozan de protección legal. En este estudio examinamos la biodiversidad, identificamos las amenazas antropogénicas más inmediatas y discutimos el hábitat crítico para la conservación de la diversidad de anfibios y el papel de las áreas actualmente protegidas en el cumplimiento de los objetivos de conservación en Marruecos, Sáhara Occidental inclu- ido. El área de estudio alberga 14 especies de anfibios, ocho de las cuales se asignan a las categorías de En Peligro (Pelobates varaldii), Vulnerable (Salamandra algira, Amietophrynus xeros y Hoplobatrachus occipitalis) o Casi Amenazada (Pleurodeles waltl, Alytes maurus, Bufo spinosusy Barbarophryne brongersmai), utilizando criterios de la UICN a nivel regional en la zona de estudio. La pérdida de hábitat y la degradación debido a la conversión de ter- renos para la agricultura, urbanismo o industria son las principales amenazas, pero las infraestructuras relacionadas con el turismo, la contaminación de agua dulce por productos químicos, la introducción de especies exóticas en los ecosis- temas acuáticos (Gambusia holbrooki), la llegada de patógenos (Batrachochytrium dendrobatidis), los atropellos y los desastres naturales (sequía), también son amenazas en rápido aumento. Del mismo modo, también deben tenerse en cuenta las consecuencias del calentamiento global.
