Roraima is one of the two Brazilian states that was born from the Federal Constitution of 1988. The state is located north of the Brazilian Amazônia and covers roughly 225,000 km². It borders the Cooperative Republic of Guyana (formerly British Guiana) and the Bolivarian Republic of Venezuela, with the states of Amazonas and Pará. The whole state occupies around 2.6% of the Brazilian territory and 4.5% of the Brazilian territory. Legal Amazon.

The state of Roraima presents basically a vegetative composition in which the humid forests predominate, represented by the phytoecological units: Dense Ombrophylous Forest, Open Ombrophylous Forest, Seasonal Forest and Alluvial Ombrophylous Forest, and in the central and north-northeast , the savannah areas in their most diverse features.

The forests are predominantly of the rainy or ombrophilous type in the southern and seasonal part in the central and northern part of the state. They have a spectrum ranging from terra firme forests to those of periodically flooded floodplains. The alluvial forests are restricted to the floodplains of the main watercourses, as well as to some flooded areas of the southwest region, these interspersed with features of campinarana and pioneer formations.

The features of savannas, which dominate the central and north-northeast part of the state, are in tree, park and grassy forms. In the extreme north of Roraima one observes the feature characterized like esthetic, in the arboreal forms and park. At present, there is a high degree of anthropism in the environments dominated by the savannas, represented mainly by the occupation with pastures and crops, as well as altered abandoned areas.

In addition to the phytoecological units represented by the various forms of Campinarana and Pioneer Formations, areas of ecological tension or transition (contacts) can be evidenced in the State of Roraima between the two forest features, between savannas and forests, between campinarana and forests and between pioneer formations and forests.

Biodiversity, scenic waters and exotic beauties, richly scattered in varied and readily accessible environments, are important for social development. Its ethnic-cultural constitution is unique, in that more than 50% of the State is made up of indigenous lands and the whole lives in the same space, although enclosing diverse cultural elements.

Its exploitation can only be made via the environment, society and economy equation.

The Roraima Forest still represents the vulnerable point of the development of the young state. Illegal logging and the predominance of archaic production methods, such as the use of fire, are still vivid and priority issues for current environmental management.

Deforestasi di Roraima pada dasarnya terjadi karena penggunaan alternatif tanah yang sesuai dengan proses pendudukan tanah dan eksploitasi ekonominya melalui pertanian dan peternakan.

Penggunaan pembakaran untuk membersihkan area sering memuncak dalam kecelakaan hutan, ketika api di luar kendali dan mencapai saluran besar vegetasi.

Penebangan juga merupakan faktor yang relevan untuk dianggap sebagai penyebab deforestasi. Meskipun sebagian besar dari mereka berlisensi, masih ada penebangan liar di daerah-daerah terpencil, termasuk di daerah-daerah adat.
