Temporal evaluation of the Conservation Priority Index for medicinal plants

Abstract

We investigated, through a temporal comparison, the extraction of non-timber forest resources by quantitatively analyzing the Conservation Priority Index (CPI). Th e study focused on the Fulni-ô Indigenous Territory, in the municipality of Águas Belas, PE (Northeast Brazil), which is characterized by caatinga vegetation (seasonal dry forest). Information on the availability of the exploited resources and the reported use of the species were obtained from vegetation sampling and semi-structured interviews, respectively. Our results demonstrated a reduction in species richness overtime, which may be due to continued resource extraction in the area, and that some species with low densities were even more aff ected. Th e species reported as being at high risk in the current study apparently did not diff er from their status in the previous study, which supports the idea that these species are most evident in this situation more for their high potential of use than for their high densities. When we associate these events together with the disappearance of some rare species, we can conclude that the CPI was not effi cient in predicting changes, and that the combination of variables used with the biological variables of the species needs to be adjusted.

Market integration does not affect traditional ecological knowledge but contributes additional pressure on plant resources

“…These results have some implications for conservation. Many of the plant species used for the production of handicrafts have other local uses for the Fulni-ô (Albuquerque et al 2011a; b; c; Soldati & Albuquerque 2012), especially the extraction of bark for medicinal purposes, such as Myracrodruon urundeuva and Mimosa tenuiflora, which also have associated timber uses in the studied region (Souza et al 2017). Versatility in the use of species is common in seasonal dry forests (Albuquerque 2006;Albuquerque et al 2008).…”

“…seeds) and those that did not have reproductive organs at the moment of the guided tour were identified through the Flora of Brazil database (floradobrasil.jbrj.gov.br), using the search by the vernacular name and the geographical distribution to guide the identification. We also consulted previous studies carried out in the Fulni-ô Territory, such as Souza et al (2017) and Albuquerque et al (2011a).…”

Conhecimento botânico local de agricultores do semiárido do estado da paraíba, nordeste do brasil

“…Em pesquisa realizada em território indígena Fulni-ô, no estado do Pernambuco pesquisadores utilizaram um outro índice (IPC -Índice de Prioridade de Conservação) que engloba dimensões biológicas e culturais, e utiliza dados sobre área de extração, método e frequência de coleta e importância local, para determinar prioridades de conservação local de plantas (Dzerefos & Witkowski, 2001) Concluíram que o IPC não foi eficiente para a previsão de mudanças relacionando conhecimento tradicional, prioridade de conservação de espécies e o desaparecimento/disponibilidade de espécies raras na vegetação local (Souza et al, 2017).…”

Evaluation of conservation status of plants in Brazil’s Atlantic forest: An ethnoecological approach with Quilombola communities in Serra do Mar State Park

“…To identify the degree of risk of collection of each species, we used the Conservation Priority Index (CPI) [5,14,[32][33][34][35]. For all native species recorded from the transects, we carried out a bibliographic search to obtain the current state of conservation of these in Flora brasiliensis [36] and in the manual "Atlantic Forest Plants" [37].…”
