and that the population is recovering here. they re doing well. they started with the introduction of 1,500 animals, so now we re talking about from 1,500 individuals now to tens of thousands, and now what we re seeing that the species is slowly starting expanding to the river system, which is exactly what we wanted. so that is a very good start, and hopefully that will be more species looking forward. among the estimated 1 million species under threat around the world, a third of wildlife that depends on freshwater habitats are sliding towards extinction. and the ongoing loss of clean, healthy rivers and lakes threatens our food and water supplies too. so here injalisco, mexico, the community stepped in. local people trained with the scientists to take on long term monitoring of this vital river network to ensure it is clean and healthy for both people and wildlife. it would be impossible without the local community. the local people are the main actors in the long term conservation p

our science correspondent victoria gill reports. a little known species with an extraordinary story. the tequila fish is a small freshwater fish that lives in the rivers and lakes of south west mexico, but it s been missing, presumed extinct, for more than a decade. and it s just one of thousands of aquatic creatures that are facing extinction, but have slipped under the radar. small little things, a bit silver sometimes, a bit of colour when they breed, but not much interest on the global conservation aspect. now, with the help of conservationists at chester zoo, scientists in mexico have reversed that extinction, bringing captive bred fish back to the wild. the team has now confirmed that the fish are breeding, and that the population is recovering here. they re doing well. they started with the introduction of 1500 animals, so now we re about from 1500 individuals now, to tens of thousands, and now what we re seeing is that the species is slowly start expanding to the river system,
