I can start, but certainly my colleagues should jump in.
Critical habitat identification is not easy. It starts, first and foremost, with the COSEWIC assessment. The COSEWIC assessment lays out the biology of the species, the type of habitat it needs, and the threats that are leading to the species being at risk. Then the job is done; they make their decision based on these quantitative criteria and indicate if it's threatened, endangered, or extirpated. It's only for those three categories that you would have critical habitat requirements.
They also provide a general notion of where you would find the species, such as in southern B.C. or up in the north, but it's pretty much at a jurisdiction level. We then receive that information, and that's what starts the recovery planning process.
For a federal species, as opposed to a species within the jurisdiction of a province or territory, we would look at who the right people would be to put on a recovery team. The Wildlife Service that I lead has staff across the country in five regions. If it's a species that's primarily in the Atlantic region, obviously folks in the Atlantic region would lead with this. Is it a species found only in parks? If that's the case, then Parks Canada would lead. If it's broader than what's found in parks, typically the Wildlife Service would lead if it's a federal species. If it's a federal species--for example, a migratory bird--we typically have the expertise that we need, but we like to involve the province and territory to the extent that they can participate.
We form a team. Then we take the information from the COSEWIC assessment and start to look at the key threats and the critical habitat. They've given us a sense of the biological needs and the features of the habitat; now we have to put the marker on the land, if you will. You have to be able to actually identify it. It's not enough to say that it's generally over here; it has to be these coordinates, or at the edge of this lake. It has to be something that would easily tell somebody who is not a biologist whether they were in critical habitat or not.
We also have to identify the features of that particular landscape that make it so important to the species. That work takes some time. It requires fieldwork, with biologists going out and looking at the field, and it requires pulling out information that exists in literature, information beyond what was provided to us from COSEWIC. That definitely takes some time. Quite often. two or three field seasons are needed before you can start to understand whether it is critical habitat or whether the bird laid an egg there once and never came back and it's not really critical to the bird. That takes some time to work through.
Once we have that piece, the other parts of the recovery strategy can be developed in parallel. You need to look at what can cause destruction of the critical habitat. That's what the biologists spend many hours and many weeks on. Quite often, they have to go out onto landscapes, and if that landscape is owned by a private individual or is aboriginal land, there are some challenges around that. We need to work with people, we need to build awareness, and we need to build understanding.
We eventually get to the point of having a recovery strategy. We have 119 recovery strategies, some of which have critical habitat identified.
Then we need to do what's called compliance promotion. We need to develop materials that speak to the landowner or the aboriginal band or whomever, explaining that they have critical habitat on their land. It doesn't mean it's a no-go zone, but we indicate the kinds of activities that they should not do on the land because they would destroy this critical habitat, which is prohibited under SARA. We work on compliance promotion materials; then we get the enforcement boots on the ground to follow up and ensure that the compliance is happening.
It does take time. It's a bit complicated, because biology is never easy.
