For this reason Copo is important to National Parks effort to preserve a good sample of each of the biomes of the country.
The Santiago quebracho is the species here present, typical of the drier areas of that huge biome which occupies all north central Argentina, western Paraguay and a bit of eastern Bolivia. Quebracho has a straight trunk of heavy and extremely hard red wood.
The "white" quebracho, also found in the park, is much sought for burning charcoal or for firewood.
The effect of cattle grazing has also been a factor in the diminution of the area occupied by these species. Of the 80% of the province's area which was once covered by these woods at the beginning of the XX century, only slightly over 20% remains today, and that has been impoverished by selective logging and grazing.
For this reason Copo is important to National Parks' effort to preserve a good sample of each of the biomes of the country. It also possesses a good population of several threatened species of wildlife such as the jaguar, the giant anteater, the giant armadillo and the chacoan peccary, a species known till recently only from sub-fossil remains but discovered alive and kicking in the seventies.
The turquoise-fronted amazon (a parrot much sought for the pet trade for its excellent capacity to "talk"), here finds refuge and the large trees (with hollows) that it needs for nesting, as does the crowned eagle, and the rhea.
