It is part of the Amazon biome and its typology is Dense Ombrophilous
Forest with solid ground.
On the opposite north facing slope, are 103 ha of an ombrophilous
lower montane cloud forest (Huber & Alarcon, 1988; Bruijnzeel, Mulligan, & Scatena, 2011) that surround nine hectares of a long (> 60 years) abandoned coffee plantation.
Its natural habitat is within the Cerrado biome, Brazilian tropical savanna, in the Ombrophilous
Forest and in the Mixed Ombrophilous
The majority of floristic inventories involving ferns and lycophytes have been carried out in the eastern portion of this region, in areas dominated by ombrophilous
forests (Oliveira-Filho et al., 2015).
The soil is classified as Yellow Latosol (oxisol) with loamy texture, and a predominant vegetation of dense ombrophilous
type of terra firme (Rodrigues et al., 2001).
The Lower Highland Seasonal Forest is inserted in this area (OLIVEIRAFILHO, 2009), and many authors such as LEITE & KLEN (1990) denominate it as a Transition Forest because it is located between the Submontana Seasonal Forest and the Mixed Ombrophilous
Forest (IBGE, 2012), having many species of both phytogeographic formations as well as its own characteristics.

forest in Sao Francisco de Paula, RS; and Silva et al.
Araucaria or Parana pine [Araucaria angustifolia (Bertol.) Kuntze, 1898] is an endangered tree species of the Mixed Ombrophilous
Forest, commonly known as "Mata das Araucarias," located in southern and the southern east of Brazil and in portions of Argentina and Paraguay [1, 2].
The species endemic to Brazil, occurring in Alagoas, Bahia, Ceara, Distrito Federal, Goias, Maranhao, Mato Grosso do Sul, Minas Gerais, Parafba, Pernambuco, Piauf, Rio Grande do Norte, Sergipe and Tocantins, and is normally associated with caatinga, cerrado and ombrophilous
forest (Irwin & Barneby, 1982; Souza & Bortoluzzi, 2015).

Clay soil is predominant and the vegetation has characteristics of a Dense Submontane Ombrophilous
Forest (Embrapa, 2013; Vibrans et al., 2013).
