It is something that is continuously studied. I think we have a very good understanding of what we're doing, but our understanding keeps improving. Tests can continue, but what gets valued on the land and what we as a society decide to focus on also change over time. Achieving these evolving objectives also requires continuous research to see if it's going to work.
For example, nowadays, trying to help woodland caribou recover is a top issue. There's a variety of approaches being tested now to see how it can be achieved. That requires quite a bit of research, because you can't rely only on a baseline hypothesis and apply it across the full landscape in the hope that it's going to work in each case. You need to continuously research your management approaches to test whether or not they are meeting the objective. That's both in terms of research and in terms of maintaining systems of continuous learning in place.
