Abstract: Resumo Nas cangas da Floresta Nacional (FLONA) de Carajás e no Parque Nacional dos Campos Ferruginosos (PNCF) foram registradas 856 espécies, distribuídas em 116 famílias de fanerógamas. As famílias mais ricas foram Poaceae (86), Fabaceae (65) e Rubiaceae (46). O hábito herbáceo foi o melhor representado. Dois gêneros, 24 espécies e uma subespécie são apontadas como endêmicas das cangas da área de estudos. Na FLONA de Carajás, a Serra Norte, com maior amostragem, possui 659 espécies de fanerógamas e na Serra S… Show more

“…The predominance of trees over other types of habits has already been observed in another study conducted in the Amazon Forest (Garcia, Silva, Zonetti & Romagnolo, 2011) and follows the general pattern recorded for the Amazon phytogeographic domain (BFG, 2015). In turn, the herbaceous habit is better represented in open areas, as already reported by Mota et al (2018).…”

“…Compliance with legal demands brought opportunities for research, which has contributed to increasing the knowledge about flora in canga of the CMP [4] and in other Brazilian mining sites located in Minas Gerais, Bahia, and Mato Grosso do Sul (Fig 1). However, it is clear that there are few floristic links between the Amazonian canga and the species found in the Brazilian cerrado, which are prevalent in the Amazonian savanna in lowlands, sandy soils, or on top of plateaus, as seen between Venezuela and Suriname [12]. Two locations within our study area, the cangas of the Carajás National Forest (CNF) and the Campos Ferruginosos National Park (CFNP), contain 856 seed plant species, most of which are herbs (40%), with 24 endemic species.…”

“…Violão Lake is located on the South Ridge of the Carajás Hill region, more specifically in the S11 southern plateau border, in the southeastern Amazon region, Brazil (Figure 1). The S11 ridge slopes are marked by open rainforests over colluvial detritic crusts and mafic rock plateaus (Guimarães et al, 2014), while iron-ore duricrusts and detritic crusts widely covered by scrubby canga vegetation occur on top of the plateau (Mota et al, 2018). This area has a tropical humid climate, with a mean annual air temperature of approximately 26°C and annual precipitation ranging from 1800 to 2300 mm concentrated from November to May (1550mm) (Moraes et al, 2005), which is characteristic of a monsoon climate (Alvares et al, 2013).…”
