Mapping and evaluation of the state of conservation of the vegetation in and surrounding the Chapada Diamantina National Park, NE Brazil

Abstract

Abstract:The Chapada Diamantina National Park (CDNP) was created in the midst of a densely populated area, and significant sections of the reserve are still undergoing processes of natural regeneration after intensive diamond mining activities were initiated in the mid-1800's. An up-to-date vegetation map was needed in order to indicate the types and distribution of regional vegetation assemblages in an easily interpretable manner and at an appropriate planning scale that could be easily consulted by decision makers and other interested groups at all levels of conservation (and development) planning. A vegetation map of the Chapada Diamantina National Park, and the areas immediately surrounding it, was prepared that: 1) delimits, describes, and maps the regional vegetation assemblages; 2) provides an indication of the degree of conservation of the mapped vegetation; 3) develops this information in a format that facilitates continued updating and revision as more information becomes available, enabling the monitoring of the evolution of the Park lands, and; 4) presents this information in a manner that can be easily interpreted and used for planning, management and conservation purposes. The resulting vegetation map revealed intensive anthropogenic disturbances in forested, savanna, and semi-arid areas subjected to intensive agricultural use outside of the Park boundaries. The National Park lands are generally well preserved but burning has replaced formerly extensive forest areas with open sedge meadows. In spite of intensive modification of the regional vegetation, two well preserved areas with high priority for conservation efforts beyond the National Park limits were identified and characterized. The vegetation mapping of the park itself can aid in the preparation of its management plan and in the reformulation of the existing boundaries of that reserve.

Um mapa atualizado da vegetação regional elaborado de maneira que facilite sua interpretação é imprescindível para orientar administradores e outros grupos interessados na preservação e desenvolvimento da região. Um mapa da vegetação do Parque Nacional da Chapada Diamantina e as áreas no seu entorno foi preparado: 1) delimitando e descrevendo os vários tipos de vegetação regional; 2) fornecendo indicações do grau de conservação da vegetação; 3) apresentando estas informações num formato que facilite sua revisão e atualização; e 4) apresentando estas informações de maneira fácil de in...

Antimicrobial Activity ofLippiaSpecies from the Brazilian Semiarid Region Traditionally Used as Antiseptic and Anti-Infective Agents

“…In Brazil, L. origanoides is popularly known as “salva-de-Marajó and “alecrim d'Angola.” The leaf infusions are used as a general antiseptic for the mouth, throat, and wounds, for the treatment of baby colic, diarrhea, indigestion, flatus, heartburn, nausea, vaginal discharges, menstrual complaints, and fever [5, 6]. L. alnifolia is also known as “alecrim-do-mato,” “pedrécio,” and “alecrim-de-vaqueiro.” The leaves are employed as a topic antiseptic against dermatitis and dandruff, as well as an oral antiseptic and in vaginal infections [7, 8]. Aerial parts of L. thymoides , known as “alecrim-do-mato,” are used in the treatment of skin infections [7].…”

“…Antimicrobial activity has been reported to L. origanoides , though it was related to the leaf essential oils [7, 9–11]. Therefore, a bioprospecting study was designed to investigate the antimicrobial activities of L. alnifolia , L. origanoides, and L. thymoides extracts from the Brazilian semiarid region against bacteria and yeasts, in order to select the most active species.…”

Composição florística e fisionomia de floresta estacional semidecídua submontana na Chapada Diamantina, Bahia, Brasil

“…Na região central da Bahia situa-se a Chapada Diamantina, local de diversidade florística elevada, associada à presença de variados tipos de vegetação que incluem cerrados, florestas, caatingas e campos rupestres (Harley 1995;Funch et al 2009). As florestas estacionais encontradas na borda leste da Chapada Diamantina foram caracterizadas através de seu componente arbóreo e de aspectos da topografia e solos, sendo identificadas florestas ciliares, florestas de encosta, florestas de planalto e florestas de grotão .…”

“…(Funch et al 2009). Orchidaceae is one of the principal groups found in that habitat (Conceição et al 2007a), with approximately 300 species (Brito & Cribb 2005).…”
