Yes. All three departments, in developing a recovery strategy, look at the threats in terms of what is causing the decline or threatening the species at risk under discussion. So we would look. In some cases, it's habitat--loss, fragmentation, or the poor quality of the habitat available. But in other cases it might be disease. In other cases it might be disturbance of beach fronts--I'm thinking of the piping plover--and so on. Different species face different threats. The 486 species are all different. They all have their own biology. They all face their own threats, depending on where they are located across the country. So management actions are definitely a key piece in how to recover a species.
Speaking to the legal description of “critical habitat”, if you are going to have a legal description of “critical habitat”, you need to be able to define it in specific terms. That's just part of the implementation of the act.
