Created in September 1982, the Carlos Botelho Sate Park is one of the 26 protected areas administered by the State of São Paulo Government (Fundação Florestal / Instituto Florestal). The region is the site of important sources of the Ribera do Iguape River. Several rivers are drained into the Juquiá river, an important tributary of the Ribeira do Iguape River. The following elements were identified in the park:
- 1,110 species of vascular plants, 39 endangered tree species
- 70 amphibian species, 4 of them endangered
- 111 mammal species, 20 of them endangered, such as the muriqui or mono-carvoeiro (Brachyteles arachnoides)
- 342 bird species, 29 of them endangered, including the Jacutinga (Aburria jacutinga)
- 31 reptile species, 5 of them endangered
The MP, coordinated by Ekos Brasil, was elaborated in thematic modules, always based on the assessments that enhanced previously generated knowledge; from the assessment analysis, primary surveys were carried out and also defined the characterization of the Park as a whole.
The result revealed novelties and highlighted the already known issues: the characterization of the physical environment indicated that the Park is a significant water donor, and with exception of a certain small stream, it does not receive contributions from outside drainage, i.e. the Park is protected against potential contamination from external rivers; the biodiversity characterization indicated the presence of a great variety of vegetal physiognomies, some of them very rare for the Atlantic Forest biome, but it also revealed a new concern related to the large areas occupied by bamboo trees, both in the PECB and in neighbouring parks; the characterization of the anthropic environment, amongst other points, indicates the incontestable urgency in defining joint solutions to the juçara palm heart issue, considering both the relevance of its suppression to the fauna and the forest balance and the established socio-environmental conflict, mainly within the Vale do Ribera.
Many other subjects were highlighted in the MP: the fauna richness in all studied groups, the efficient management of public visitation, and the definition of a relationship with local and regional partners based on recommendations established for the Buffer Zone and many others.
