If I may, I can try to answer the question, Mr. Chair.
Yes, we do take that into account. As mentioned earlier, each region is different and has its own unique characteristics. In many regions, the deeper roots of some plants are more effective. It may be different in other areas. That's why we have 20 research centres across Canada—it's a big country—with researchers in every province and every region. They study the ecosystems so they can make specific recommendations based on each microenvironment.
As my colleague Mervin St. Luce mentioned, there's no one size fits all approach, but we do have researchers working hard across Canada to make specific recommendations on this.
