Spanish Association for the Conservation and Research of Bats


Our Association

The Spanish Association for the Conservation and Research of Bats (SECEMU) is a non-profit national organisation which brings together people interested in conducting research and developing conservation activities in relation to the bats of Spain, with a particular emphasis on promoting their protection.


SECEMU was founded in 1989 and registered in the National Registry of Associations in 1991 with the number 90757.




Our headquarters are located at:

Council (2018-2022)

Juan Tomás Alcalde

Juan Tomás Alcalde (Navarre) is a PhD in Biological Sciences, working on conservation projects of bat populations, installation and monitoring of bat boxes and research into the impact of wind farms on these mammals.

Javier Juste

Javier Juste (Seville) is an Adjunct Professor at the Spanish National Research Council (CSIC) and assigned to the Doñana Biological Station (EBD). He is a member of SECEMU almost since its inception and has throughout his life combined research activities (ecology and evolution of bats) with conservation, both theory and practice, especially as a United Nations expert in Central Africa.

Maria Mas

Maria Mas Navarro has a degree in Biology from the Autonomous University of Barcelona and a Master’s degree in Biodiversity from the University of Barcelona, where she researched the vertical stratification of the insectivorous bat communities of the Central Amazon. She is part of the bat research team at the Museum of Natural Sciences of Granollers, where she carries out projects on the conservation and dynamics of bat populations. She is currently working on her doctoral thesis on the relationship between wetlands and bats.

Xavier Puig Monserrat
Deputy secretary

Xavier Puig Montserrat has a degree in Environmental Sciences, and carries out bat research and conservation projects focusing on the study of communities and pest control within agroecosystems from the Galanthus Association and the Museum of Natural Sciences of Granollers.

M. Jesús Celaya

María Jesús Celaya has a degree in Physical Sciences and a degree in Environmental Sciences. She currently collaborating in the production of the bat atlas.

Juan Emilio Echevarría Mayo
Council member

Juan E. Echevarría is a virologist at the National Centre for Microbiology (Carlos III Health Institute), where he is responsible for the National Rabies Reference Laboratory. He is Coordinator of the interdisciplinary VIROBAT projects on the search and characterisation of viruses associated with bats, where in this context some have been describes such as the LLoviu filovirus or the Lleida lisavirus, potentially relevant both for human health as well as the conservation of bats. The description of co-evolution models between viruses and bats and their application, both to the systematics of bats as well as to the study of interspecific transmission, is another of the basic lines of research of VIROBAT. He has been responsible over several years for the Health Section of SECEMU, which aims to ensure the implementation of best practices that safeguard both the health of handlers as that of the bats.

Stewart Finlayson
Council member

Stewart Finlayson is a Biologist and Director of Natural History at the Gibraltar National Museum. He is coordinator of the Gib-Bats project which studies the biology of bats on the Rock of Gibraltar. He also works in different parts of Andalusia. Stewart is currently studying for a PhD, specialising in the evolutionary ecology of vertebrates. He has a special interest in vertebrate cave-dwelling species and in the use of vertebrates as bioclimatic indicators. More recently Stewart has been linked to the Rewilding concept.

David García
Council member

David García (Balearic Islands) is a naturalist dedicated to the study of bats in the Balearic Islands. He carries out work monitoring colonies of cave-dwelling bats throughout the archipelago, installing and monitoring bat boxes and researches the movement patterns and population dynamics of the bats within the islands.

The SECEMU Council was elected at the Extraordinary General Meeting held on 2nd December 2017 in Alcalá de Henares (Madrid). The Council consists of eight people from different areas of the Iberian Peninsula and its islands, from the most varied personal and professional profiles, but all with the common passion for bats.
