Описание
In order to improve our knowledge on wood plants of these regional ecosystems we carried a tree inventory in four different habitats occurring in indigenous savanna areas of the Northern Brazilian Amazonia. The habitats were divided into two formations: forest (Alluvial forest, Forest island and Buritizais = buriti palm formation) and non-forest (typical savanna). The inventory was carried out on two hectares established in the Darora Indigenous Community region, north of the State of Roraima.

Географический охват
The study area is located in the Darora Community, a Makuxi ethnicity group living within the São Marcos Indigenous Land. Based on data from the Boa Vista weather station, the climate in Darora can be defined as tropical (Aw) according to the Köppen classification, with average annual temperature of 27.8 °C, and average annual rainfall of ~ 1.650mm, with the driest period concentrated between the months of December and March (± 9% annual precipitation), and the wettest period being between May and August (± 70% annual precipitation). The study included four habitats occurring in lavrado area which are used by indigenous from Darora: typical savanna (non-forest formation) and three forest environments (Alluvial forest, Forest island and Buritizais = Mauritia palm formation).

Таксономический охват
The study registered 52 species belonging to 28 botanical families (Table 1). Only 13 species were identified at the genus level. The families with the greatest richness in species (S) were Fabaceae (12 spp.) and Malpighiaceae (5). Nonforest areas (typical savanna) are the most densely populated by tree individuals (709 ind ha ); however, they presented lower richness (nine species) when compared with typical forest habitats: riparian forest (22 species, 13 families and 202 ind ha ), forest island. (13 species, 10 families and 264 ind ha ) and buritizais (19 species, 15 families and 600 ind ha ).

Eight plots were installed (each 0.25 ha) at different distances from the Community: four in typical savanna area (nonforest), and another four in several forested habitats (two in riparian vegetation of the Takutu river, one in a buritizal along the Maracajá igarapé (stream), and one in an isolated natural forest island). Each plot was divided into 10 25m x 10m subplots. In the nonforest plots, all trees with diameter greater than or equal to 2 cm, at 2 cm from the soil (DSH ≥ 2 cm). In the forest plots, all individuals with DBH (diameter at the breast high – 1.3 m) ≥ 10 cm were measured. Additionally, the maximum height of each individual was visually estimated.
| Охват исследования | Atualmente a Terra Indígena São Marcos está dividida em três sub-regiões, onde são encontradas 38 comunidades das etnias Macuxi, Wapixana e Taurepáng: ao norte, denominada Alto São Marcos, região serrana com a presença de floresta ombrófila, encontramos 20 comunidades, principalmente da etnia Taurepáng; ao centro, Médio São Marcos; e ao sul, Baixo São Marcos, ambas com nove comunidades e caracterizadas pelas fisionomias das savanas de Roraima com as etnias Macuxi e Wapixana. Em termos hidrográficos, a TISM apresenta os rios Parimé e Uraricoera, a oeste; Miang Surumu e Tacutu a leste, ainda os rios Samã, Surumu, Paricarana e Maruwai, além de igarapés e lagos. A TISM apresenta cinco tipos vegetacionais, no Alto São Marcos, sendo eles: a Floresta Ombrófila Densa Submontana e a Floresta Estacional Decidual, sendo considerados ecossistemas ricos em espécies madeireiras, apesar do porte baixo, destacando-se o pau-roxo, Peltogyne gracilipis Ducke; no Médio São Marcos, encontra-se o Lavrado caracterizado principalmente por Curatella americana L. (caimbé) e Byrsonima crassifolia (L.) Rich. (murici) além da Mata Ciliar e da Mata de Galeria; e no Baixo São Marcos apresenta a savana estépica e arbórea. |

| Контроль качества | Samples of the species were collected, and taxonomic identification was performed by botanists, parabotanists and local flora guides. Samples were placed in the herbarium collection of the Universidade Federal de Roraima (UFRR), Boa Vista. Botanical classification followed the APG IV (2016) system. All required federal permissions were obtained (FUNAI: Process 08620.002869 / 201415; IPHAN: Process 01450.001678 / 201488; CEPINPA / CONEP: 814370). |
