According to scholars, there are over a thousand vegetal species in this park, from which six hundred plus have been catalogued. Some plants found in the park show curious morphological adaptations that combine to resist droughts. In some cases leafs change position to protect themselves from the sun.
Contrary to what may be believed, the climate in the world does not remain uniformly still, it changes and presents cycles.
The average temperature can raise or lower; the winds regime change and consequently the marine currents are altered. These phenomenons originate the climate changes. The annual average temperature is of 28° C; the rainy season goes from October to the early days of May. The hottest period of the year goes from October to late November, when the average temperature is of 35° C.
There are records showing that temperature in the region has reached a staggering 47° C. Temperatures can drop to minimums close to 10° C in June, the coldest month of the year.

It keeps samples of the discoveries made by the investigators studying the region. Amongst the exposed pieces, the mandibles of a sabre tooth, fragments of a fossilized cranium, pottery almost 9 thousand years old, and a hatchet made of polished stone 9200 years old, stand out.
There are more than 400 galleries with rock paintings - kind of archaeological country houses - with scenes depicting sex, dancing, hunting, wars, crops and games. It is located at Son Raimundo Nonato.
The 48 archaeological sites have foot bridges to facilitate the observation of the rock paintings, and can be visited following 14 predetermined paths either by foot or by driving a sports utility vehicle.
Some of these paths are long and go across hard to access terrains. The Toca do Boqueirão da Pedra Furada shows inscriptions of various prehistoric periods on a 70 metre wide huge wall.
At the Sítio do Meio, besides the rock paintings, archaeologists have found vestiges of instruments used by the ancient inhabitants, such as objects made of chipped stone and fragments of pottery.
