“…The relationship between age and the number of plants cited for medical use was also observed in other studies (Voeks & Leony, 2004;Almeida et al, 2010;Parveen et al, 2007). The greater knowledge of older people, as observed in this study, may be related to the degree of opportunity that they have had to learn about medicinal plants and their therapeutic uses; for older people, it appears, there is more experience and contact with these resources.…”

Human beings have accumulated rich experience with natural resources over time, but such knowledge can be strongly infl uenced by several factors, such as age, sex and occupation. This study focuses on the infl uence of these factors on knowledge of medicinal plants in a rural community in northeastern Brazil. Data were collected through semi-structured interviews with 102 people, with the number of plants and uses cited studied for quantitative analysis. Through this research, it was possible to show that the social variables studied (age, sex and informants occupation) have contributed to the formation of different patterns of knowledge regarding medicinal resources. The results indicate that awareness of this dynamic is necessary for the proper implementation of projects where the goal is the sustainable use of natural resources (because it indicates the different levels of knowledge within a community), for studies intended to discover new drugs (because it indicates the peculiarities of certain groups), and for biodiversity conservation strategies.

“…The same observation has been made in most places where this question has been studied (Mexico, Argentina, Mozambique, Brazil (Estomba et al 2006, Coelho-Ferreira 2009, Bruschi et al 2011, with very few exceptions (de Almeida et al 2010). This shows that people regularly use their own surroundings for their medicinal plant needs, but adopt new plants rapidly (see the Aloe example) if they satisfy a need.…”

Can the use of medicinal plants motivate forest conservation in the humid mountains of Northern Oaxaca, Mexico?

Background. Non-timber forest products are being integrated into conservation strategies. Their relevance for obtaining medicinal plants is frequently cited as a reason to conserve forests. Question. Can the use of medicinal plants motivate forest conservation? Study site and dates. The study was conducted in Santiago Camotlán, Distrito Villa Alta, Oaxaca, a humid mountainous area in the Sierra Norte of Oaxaca, Mexico, from August 2011 to May 2013. Methods. Ecological Land Units were characterized, and the relative importance of medicinal plants was evaluated. The ethnobotanical methods included participatory mapping, open interviews, semi-structured interviews and free lists with local healers, as well as members of 17 systematically selected households. Medicinal plant species, and plants considered characteristic for an Ecological Land Unit by local specialists, were collected during plant walks with both healers and experts on the territory. For each species, a newly proposed Knowledge, Use and Perception Index based frequency of mention in free lists, frequency of use and perceived importance was calculated. Results. Local people divided their territory primarily by physical geographic characteristics and utilization. Nine units were distinguished: village and roads, home gardens, pastures, cultivated fields (maize, beans, sugar cane and coffee), cloud forest, semi-evergreen tropical forest and evergreen tropical forest, secondary vegetation ("acahuales"), and riparian vegetation. The most important medicinal plants were Salvia microphylla, Lippia alba and Artemisia absinthium, all cultivated in home gardens; weedy vegetation provided the majority of all medicinal plants. Individuals interested in preserving medicinal species transplanted them into a home garden. Conclusion. For people in the study area, the presence and use of medicinal plants was not a decisive reason for forest conservation. Key words: Ecological Land Units, home gardens, Knowledge, Use and Perception Index, tropical forest, wild plant collection. ResumenAntecedentes.

Pregunta. ¿El uso de plantas medicinales puede motivar la conservación de bosques? Sitio y años de estudio. El estudio se llevó a cabo en Santiago Camotlán, Distrito Villa Alta, Oaxaca, en un área montañosa húmeda de la Sierra Norte de Oaxaca, México, de agosto 2011 a mayo 2013. Métodos. Se caracterizaron unidades ambientales y se evaluó la importancia relativa de las plantas medicinales. Los métodos etnobotánicos incluyeron mapeo participativo, entrevistas abiertas, entrevistas semiestructuradas y listados libres con curanderos, así como miembros de 17 hogares seleccionados sistemá-ticamente.

“…Fruit picking is virtually limited to extractivism as hardly any plantations have been established (Narain et al, 1992;Neves et al, 2004;Neves and Carvalho, 2005). Moreover, S. tuberosa is used in traditional medicine and shows potential for its use in academic medicine Albuquerque and Oliveira, 2007;Almeida et al, 2010;Ferreira Júnior et al, 2011;Lins Neto et al, 2010;Silva et al, 2011).…”

Spondias tuberosa Arruda (Anacardiaceae), a threatened tree of the Brazilian Caatinga?

et al. 2016

Spondias tuberosa Arr., a fructiferous tree endemic to the northeast Brazilian tropical dry forest called Caatinga, accounts for numerous benefits for its ecosystem as well as for the dwellers of the Caatinga. The tree serves as feed for pollinators and dispersers as well as fodder for domestic ruminants, and is a source of additional income for local smallholders and their families. Despite its vantages, it is facing several man-made and natural threats, and it is suspected that S. tuberosa could become extinct. Literature review suggests that S. tuberosa suffers a reduced regeneration leading to population decrease. At this juncture S. tuberosa cannot be considered threatened according to the International Union for Conservation of Nature Red List Categories and Criteria, as it has not yet been assessed and hampered generative regeneration is not considered in the IUCN assessment. The combination of threats, however, may have already caused an extinction debt for S. tuberosa. Due to the observed decline in tree density, a thorough assessment of the S. tuberosa population is recommended, as well as a threat assessment throughout the entire Caatinga.Keywords: Spondias tuberosa, natural regeneration, conservation, IUCN red list, Caatinga.Spondias tuberosa Arruda (Anacardiaceae), uma árvore ameaçada de extinção da Caatinga?Resumo Spondias tuberosa Arr., é uma árvore frutífera endêmica da Caatinga, floresta seca tropical localizada no Nordeste do Brasil. A árvore traz diversos benefícios para o ecossistema e para a população local. Ela serve de alimento tanto para polinizadores e dispersores quanto para ruminantes domésticos e é fonte de renda extra para os agricultores familiares da região. Apesar de seus benefícios, esta árvore enfrenta várias ameaças naturais e antrópicas que podem levar a sua extinção. A revisão da literatura científica sugere que S. tuberosa sofre de reduzida capacidade de regeneração, o que leva à diminuição da população. Todavia, S. tuberosa não é considerada uma espécie ameaçada de extinção de acordo com as categorias e critérios da Lista Vermelha da União Internacional para a Conservação da Natureza, já que a espécie ainda não foi avaliada e capacidade regenerativa reduzida não é considerado critério pelo UICN. A combinação de ameaças, entretanto, pode já ter levado ao débito de extinção da S. tuberosa. Devido ao declínio observado da densidade das árvores, recomenda-se uma avaliação completa da população de S. tuberosa e uma avaliação de todas as ameaças sofridas pela árvore na Caatinga.Palavras-chave: Spondias tuberosa, regeneracao natural, conservação, lista vermelha da UICN, Caatinga.
