“…This study does not allow us to determine whether the charcoal we recovered was intentionally produced and then incorporated into the soil, or whether it resulted from fires set to clear the areas, or both. Nevertheless, we have found several taxa that are used for construction, crafts or as firewood by present-day Amerindian populations of French Guiana (Ogeron et al 2018;Odonne et al 2019). For example, Cupania/Matayba is the most frequent taxon in our charcoal assemblages: it was found in 7.2% of the sampling points, i.e.…”

In Amazonia, a growing body of studies has shown that rainforests were affected by human occupation? in many areas during pre-Columbian times, inducing changes in their floristic compositions. The northern part of Amazonia, and in particular the Guiana Shield, is much less studied, although past human occupations have also been documented in this region. Therefore, the actual impact of pre-Columbian societies on Guianan forests is still poorly known. Here we explore 12 sites in the dense forest of Nouragues, central French Guiana, ranging from a priori non-anthropogenic to clearly anthropogenic, using an anthracological approach. Soil charcoals were radiocarbon dated to assess the chronology of the past human occupations, and identified to determine shifts in vegetation cover. Our results show that two main periods of occupation can be distinguished on several sites in the Nouragues area: a first one between ca. 1,300 and 1,000 cal BP and a second one between ca. 600 and 400 cal BP. Charcoal identification reveals the presence of a secondary vegetation during this most recent period of occupation, as shown by the presence of pioneer and heliophilic taxa, suggesting that human activities induced and favored this kind of vegetation. The presence of valuable wood and edible species in the anthracological record could reflect selective exploitation of the former around dwelling areas and a concentration of the latter within anthropogenic sites. As shown by our anthracological results, all the sites which contained charcoal were once under forest cover, including those that are now covered by pseudo-bamboos or by liana forests. We therefore suggest that the type of human activity (e.g. dwelling or food production) may have had different impacts on the structure and composition of 2 subsequent vegetation resulting either in anthropogenic forests or liana and pseudobamboo patches after land abandonment.

To decipher the long-term influences of pre-Columbian land occupations on contemporary forest structure, diversity, and functioning in Amazonia, most of the previous research focused on the alluvial plains of the major rivers of the Amazon basin. Terra firme, that is, nonflooded forests, particularly from the Guiana Shield, are yet to be explored. In this study, we aim to give new insights into the subtle traces of pre-Columbian influences on present-day forests given the archaeological context of terra firme forests of the Guiana Shield. Following archaeological prospects on 13 sites in French Guiana, we carried out forest inventories inside and outside archaeological sites and assessed the potential pre-Columbian use of the sampled tree species using an original ethnobotanical database of the Guiana Shield region. Aboveground biomass (320 and 380 T/ha, respectively), basal area (25-30 and 30-35 m 2 /ha, respectively), and tree density (550 and 700 stem/ha, respectively) were all significantly lower on anthropized plots (As) than on nonanthropized plots (NAs). Ancient human presence shaped the species composition of the sampled forests with Arecaceae, Burseraceae, and Lauraceae significantly more frequent in As and Annonaceae and Lecythidaceae more frequent in NAs. Although alpha diversity was not different between As and NAs, the presence of pre-Columbian sites enhances significantly the forest beta diversity at the landscape level. Finally, trees with edible fruits are positively associated with pre-Columbian sites, whereas trees used for construction or for their bark are negatively associated with pre-Columbian sites. Half a millennium after their abandonment, former occupied places from the inner Guiana Shield still bear noticeable differences with nonanthropized places. Considering the lack of data concerning archaeology of terra firme Amazonian forests, our results suggest that pre-Columbian influences on the structure (lower current biomass), diversity (higher beta diversity), and composition (linked to the past human tree uses) of current Amazonian forests might be more important than previously thought.

“…O destaque dos usos madeireiros é comum em áreas rurais, onde a madeira extraída da vegetação apresenta um grande emprego no uso para construção, como combustível e usos tecnológicos, por exemplo (Ferraz et al, 2006;Soares et al, 2013;Barbosa et al, 2020). A relevância apresentada pelas categorias construção e combustível é um reflexo da importância cultural dos recursos vegetais como fonte de material para construção e como fonte de energia, estando fatores socioeconômicos entre os principais responsáveis pela dependência destes recursos em algumas comunidades (Ramos et al, 2008;Ogeron et al, 2018). Por outro lado, também é possível observar estudos onde o uso não-madeireiro, com destaque especial para o uso medicinal, é o mais citado nas comunidades estudadas (Bastos et al, 2018;Prado et al, 2019).…”

As unidades de conservação surgiram como uma resposta à necessidade do cuidado com os recursos naturais diante de sua exploração indiscriminada. A etnobotânica tem crescido substancialmente como área de conhecimento nas últimas décadas, colaborando com a compreensão das relações entre seres humanos e plantas, inclusive no estudo de espécies vegetais em unidades de conservação ou em seu entorno. O presente estudo descreve e analisa as relações de moradores da comunidade rural Cachoeira, no entorno do Parque Nacional de Sete Cidades, no Piauí, com as espécies lenhosas úteis, avaliando o uso e disponibilidade das espécies por meio de inventário etnobotânico e de vegetação. Foram entrevistados 27 moradores da comunidade, analisando os dados das entrevistas pelo método do Valor de Uso (VU). Para a fitossociologia foram registrados os indivíduos com diâmetro a nível do solo (DNS) >= 3 cm, amostrados pelo método de ponto quadrante. Foram registradas 73 espécies úteis, das quais 71 foram identificadas. Distribuídas em 64 gêneros e 30 famílias, sendo as de maior VU Aspidosperma sp. (5), Handroanthus impetiginosus (Mart. ex DC.) (4,07), Cariocar cuneatum Witm. (3,3) e Hymenaea courbaril L. (3,33). As categorias mais citadas foram construção, medicinal e tecnologia. Na fitossociologia foram registradas 34 espécies, pertencentes a 32 gêneros e 20 famílias. As famílias de destaque em número de indivíduos foram Fabaceae (339), Anacardiaceae (330) e Rubiaceae (203). Entre as espécies o destaque foi para Campomanesia velutina (Cambess.) O. Berg. (288 indivíduos), Copaifera luetzelburgii Harms (262) e Aspidosperma sp. (187). O estudo apresentou que algumas das espécies mais conhecidas na comunidade não foram encontradas no inventário da vegetação, apontando para a necessidade de maiores estudos sobre a vegetação local de modo a compreender a dinâmica de uso e sugerir estratégias sustentáveis.
