Conservação ex situ de espécies ameaçadas da flora brasileira: a contribuição do Jardim Botânico Plantarum

Abstract

Botanical gardens are institutions that develop research, conservation and education. More than seven hundred botanical gardens in 118 countries (36 in Brazil). This Dissertation explores the ex situ conservation practices of native plants in Brazil and exotic endangered held in a non-governmental botanical garden, located in Nova Odessa (SP, Brazil), the Botanical Garden Plantarum (BJP). Thus, this study aims to evaluate its live collection and the environmental education program as allies to the maintenance of Brazilian biodiversity. The research is presented in two chapters. The first brings comparative analysis of native plant species preserved in the institution (2609 spp.) with the species listed in the Red Book of the Flora of Brazil and exotic species preserved contained in the IUCN Red List 2014.3. In JBP 157 species specimens are preserved (6% of its collection of native species), totaling 33 botanical families, cited as endangered in the Red Book of the Flora of Brazil, as well as 54 non-threatened species, mentioned in that publication as of interest for research and conservation. The predominant biome of preserved endangered species is the Atlantic Forest (120 occurrences). The four botanical families under threat, best represented in the JBP collection of native species are: Cactaceae (23spp.), Gesneraiceae (21 spp.), Arecaceae (18 spp.) and Begoniaceae (15 spp.). The live collection of exotic plants from JBP consists of 1106 species, of which a total of 48 spp. (4.3% of the exotic collection) contained in the IUCN Red List 2014.3. Chapter II is an article disseminate the results achieved in the first three years of operation of Environmental Education Program of the organization, between the years 2012 and 2014. In the period surveyed more than 25,000 people were directly addressed in different ways care practiced by the organization. The main limiting aspects of the expansion of its activities to the public school system are related to the collection of entry, current impossibility of entrance fee waivers and the lack of partnership that enables meet all municipal public schools
