Resumo Mapeamento e caracterização da vegetação da Ilha de Superagüi utilizando técnicas de geoprocessamento.A ilha do Superagüi é integrante do Parque Nacional do Superagüi, que conserva em seus limites um dos mais importantes remanescentes de Floresta Atlântica do país. Superagüi é considerada uma ilha artificial, separada do continente em 1952 pela abertura do canal do Varadouro. Ainda assim, algumas espécies seriamente ameaçadas de extinção têm essa ilha como seu hábitat -são exemplos o mico-leão-da-cara-preta (Leontopithecus caissara) e o papagaio-chauá (Amazona brasiliensis) -, o que confirma a importância da sua conservação. No intuito de gerar subsídios à elaboração do plano de manejo, no que tange à vegetação, esse trabalho teve por objetivo mapear e caracterizar a cobertura vegetal de Superagüi, através de estudos de campo associados a geoprocessamento. O resultado obtido foi um mapa da vegetação que contempla 11 tipologias e dispõe de descrição geral para cada uma delas, incluindo as espécies arbóreas mais freqüentes ou importantes para o reconhecimento da classe em questão. Palavras-chave: Mapa de vegetação; geoprocessamento; Superagüi; Floresta Atlântica; planície litorânea. Abstract Mapping and characterization of Superagüi Island vegetation applying geo-processing techniques.Superagüi Island is part of Superagüi National Park, which limits preserve one of the most important remaindering areas of Brazilian Atlantic Forest. Superagui is considered an artificial island, as it was separated from mainland in 1952 by Varadouro Canal opening. Preservation of Superagüi is unquestionable as endangered species have this island as their habitat, such as black-faced lion tamarin (Leontopithecus caissara) and Chauá parrot (Amazona brasiliensis). In order to work the park running plan up, this work intended to map and clear up Superagui's vegetation aspects applying land studies associated to geo-processing techniques. As result a vegetation map was elaborated, it contemplates 11 typologies and disposes general descriptions for each one, even most frequent or important arboreal species for classification knowledge.
In Paraná, the Alto Iguacu basin is listed as one of the most important regions of the south of Brazil for water supply, in addition to the presence of several Conservation Units of different categories to protect the biodiversity of fauna and flora in the Atlantic Forest. This study aims to indicate relevant areas for the creation of ecological corridors in the Alto Iguaçu Basin using a GIS multi-criteria methodology, evaluating the plant typology, land use, and soil characteristics, and the diverse environments with the Phyto-environmental Units (UFAs) project. Tree areas were proposed to interconnect the protected areas covering the Mixed Rain Forest, Dense Rain Forest, and steppes, guaranteeing the representativeness of all Phyto-physiognomies present in the basin.
