Puyas may be hard on sheep (revenge of the flora!), but they also offer habitat to certain species. For instance, there is a species of Chinchilla in Chile that is very endangered. It nests inside big puyas for protection from predators. Conservation efforts for this animal include preserving and replanting puyas in the reserve dedicated to it. Las Chinchillas Reserva Nacional in Coquimbo province is a great place to visit. The flora is extremely varied, including Placea!, there is a good trail system, and there is also a little "zoo" where nocturnal animals are housed and you can see them through special glass; the ranger gives a talk to visitors. I also saw interesting birds in the reserve. I seem to recall there are birds that nest inside puyas as well.
