Some other reported killings in 1961 were by ranchers and houndsmen for the jaguar's head. These are just some of the examples of the careless and unnecessary reasoning behind why the jaguar is endangered today. Recovery for an endangered species requires stopping and reversing it's decline, and then insuring it's long term survival in nature. Right now, some of the things being done to replenish the species is captive breeding. There have been specific groups and organizations set aside for the jaguar, along with other endangered species, to concentrate on the survival of that animal.
Captive breeding is a very succesfull way to reintroduce the population into the wild.
Not only that, but as the numbers rise, it then becomes easier for the huge cat to find a mate and further multiply the race. Some endangered species teams have special wildlife and habitat management techniques that require a lot of hard work to protect the species as well as it's environment. Sometimes Sanctuary Reserves are created and land set aside for threatened animals so that they are protected from hunting. Often, the jaguars are dropped nutritious fofrom trucks or helicopters to increase the survival rate in harsh winters. Recovery plans differ from species to species.
