I find the IUCN discussion to be somewhat akin to measuring inputs and ignoring outputs, because any of the lands that we're talking about may not be productive, biologically, but they may be more productive if they're managed. So I think it's much more important that we measure the biodiversity outputs of the lands that we are investing in, as opposed to measuring some artificial construct of what inputs are going in.
We have that capability. For example, waterfowl get counted every spring by the Canadian Wildlife Service, and we have indexes of how many birds are in prairie Canada and across the U.S. I believe that these are much more useful measurements of the health of the landscape than some construct of whether this land is set aside or not. It may be better to manage these lands to produce wildlife than to do otherwise.
In many areas of Manitoba, for example, the most productive areas for wildlife production are on the privately owned landscape, not in the parks where the forest is over-mature and not actively managed. You find big game exiting parkland areas to go into the farmland, because that's where the food is, that's where alfalfa is for them to eat.
I think it's much more important that we focus on outputs from our investments, as opposed to the inputs. I think there are some signs of that starting to happen.
The Alberta Biodiversity Monitoring Institute has set up monitoring stations around Alberta to measure biodiversity over time, and I think that kind of model is much more interesting to me than these other categories.
I agree with you that the fact there may be some potential for subsurface development adds insult to injury. Often those developments have fractional impacts on wildlife production. Especially horizontal drilling for oil and gas, you can have oil extraction take place with minimal or no surface disturbance. To have that impact, the classification and some important yardstick, to me, is absolutely ridiculous.
