Year Published: 2006

It is estimated that the population of B. microcephalus has declined by at least 30% in the past 10 years and it is suspected to decline by the same amount in the next 10 years (Carmona, J. pers comm). The population is declining in all of its range due to dam construction (a current and future threat in Spain and Portugal: for example a dam is planned near Alquedi (Carmona, J. pers comm)), water extraction and introduced species.
Previously published Red List assessments:
