All of IUCN’s Red Listing processes rely on the willingness of scientists to contribute and pool their collective knowledge to make the most reliable estimates of species status. All the participating experts are listed at the first page of this report. Without their enthusiastic commitment to species conservation, this kind of regional overview would not be possible. Particular devotion has been shown by the coordinators of each taxonomic group evaluated in this publication – Mejdeddine Kraiem (freshwater fish), Mary Seddon (freshwater molluscs), Vincent Kalkman (Odonata), Neil Cumberlidge (freshwater crabs) and Patrick Grillas (aquatic plants) – the authors of the various chapters, assessors and participants to the different workshops.

This regional assessment of the northern African freshwater biodiversity was coordinated by Annabelle Cuttelod, Nieves Garcia and Dania Abdul Malak from the IUCN Centre for Mediterranean Cooperation. The aquatic plant component was coordinated by Melanie Bilz (IUCN Species Programme). We received extensive expert advice and assistance from the following IUCN Species Survival Commsion (SSC) Specialist Groups: IUCN/SSC Mollusc Specialist Group, IUCN/SSC Dragonfly Specialist Group, IUCN/SSC Freshwater Crab and Crayfish Specialist Group. The aquatic plant assessment was carried out in collaboration with Tour de Valat, especially counting with the support of Patrick Grillas. A special thanks also to Laila Rhazi for her invaluable contributions and obliging nature.

We would also like to thank Dr. William Darwall, Manager of IUCN Freshwater Biodiversity Unit and coordinator of the project Integration of freshwater biodiversity in the development process throughout Africa who helped greatly in the peer review of this report. Rami Salman provided guidance, encouragement, and good advice throughout the project. Jean-Christophe Vie and Margarita Astralaga provided their constructive advice.

The species distribution maps were digitized through the combined efforts of the IUCN Freshwater Biodiversity and Red List Units. Kevin Smith, Susannah Ohanlon and Vineet Katariya have provided their technical support on GIS analysis and generation of maps. Yichuan Shi, Joe Wood and Amy Milam helped with digitizing the maps. Laurel Bennett reviewed and text edited this report. Chadi Abi Faraj produced the present project publication.

Alexandra Salmon-Lefranc helped by translating the French version of the aquatic plants chapter. Ahmed Gheith drew the beautiful illustrations included in this report.

Facilitators for the training and/or review workshops were Caroline Pollock, Helen Temple, David Allen, Kevin Smith, William Darwall, Anna McIvor, Melanie Bilz, Annabelle Cuttelod, Dania Abdul Malak and Nieves Garcia. Sandra Simoes provided technical and logistical support to the workshops. We also thank the IUCN Moroccan National Committee, and in particular Mr. Brahim Haddane, who provided extensive logistical services for the GIS training workshop held in Rabat (Morocco) and conducted by Hein van Gils and Eduard Westinga from the International Institute for Geo-Information Science and Earth Observation (ITC). The Research Centre for Biodiversity and Genetic Resources of Porto University (CIBIO-UP), through Sonia Ferreira, provided the venue for the review workshop held in Porto

(Portugal) and the municipality of Vila do Conde supported the logistics. We also received extensive support from the IUCN Tunisian National Committee, and its president Dr. Abroughi, who organized the aquatic plants evaluation workshop held in Tabarca (Tunisia).
