Cougars and Karst topography

Karst topography: http://en.wikipedia.org/wiki/Karst

The Canadian Shield is the largest continuous forested region on the face of the earth. The granite bedrock is some the oldest and hardest on earth. Karst topography depends upon water and wind soluble rock and so Karst formations are rare on the Shield. Other than around the perimeter there are no Cougars on the Shield and no historical evidence they existed there. Odd considering Cougars are found in such diverse habitats all over the Amerca's.

Some of the regions across North America with highest incidence of Karst topography, IE: Black Hills, Vancouver Island etc. also have the highest Cougar populations. Coincidence?

One of requirements for a breeding Cougar population it seems is the need for secure den sites. Do areas without Karst topography not have sufficient den sites?

It is only my theory because I found no reason why a breeding population could not and does not exist on the Shield. The only area of my home Province of Ontario that has historical evidence of a breeding Cougar population is the Niagara Escarpment and Bruce Peninsula areas which....you guessed have the highest incidence of Karst topography in Ontario.

The Adirondacks are an extension of the Canadian Shield. Would Cougars if introduced to the Adirondacks stay or leave the Park for favorable den sites outside the Park?
