If I may add to that, the devil is in the details, as usual. Some species are overharvested or poached, so you don't want those to be mapped, right?
For peregrine falcon nests, are you going to post where the nests are? No. That's one example.
Another thing that becomes a real problem, especially in southern and eastern Canada where you have a lot of private land, is the nature of the land, of it being private land. If I have a woodlot there, I'm not sure that I want everybody to know that the species is there. I'm a very good citizen and I'll do all the good stewardship, but I may not want all the birdwatchers to know that they could come to my woodlot to check out that rare bird.
There is a number of difficulties with implementing such tools--and it's going to be species-dependent.
