The difficult access has, until recently,
protected the "Pantanal" from
the human impact. Only in the last decades has it begun to be exploited
by hunters for "ariranha" and alligator skins. Nowadays,
the illegal hunting and the smuggling of alligator skins are, in
general, under control; alligator breeding farms are multiplying.
The indiscriminate hunting of deer, capybaras and "baguás" (a
variety of mongrel dogs), considered to be illness spreading animals,
of piscivorous and granivorous birds, snakes and jaguars constitutes
a direct danger to the regional biological diversity.

Commercial fishing in "Pantanal" has become a serious
environmental problem, with the arrival of boats and refrigerated
trucks. Even the game fishing, more and more intense, needs severe
regulation. Individual quotas per amateur fisherman exist. However,
the number of tourist fisherman has been increasing with the growing
access facilities to the "Pantanal".
