The Cougar Fund,
As the largest ranging predator in the Western Hemisphere, cougars were once found in all 48 of the continental United States. Today, they survive in only 14. With trophy hunting, habitat loss, human development, and more and more people recreating in wilderness areas that cougars occupy, the potential for contact between man and lion greatens, further pitting the odds against the cougar's wild survival. Taking into account the startling realities facing Puma concolor, the mission of The Cougar Fund is to protect the mountain lion throughout the Americas.
