 pt ESPÉCIES EXÓTICAS INVASORAS ARBÓREAS NO PARQUE DA BARREIRINHA EM CURITIBA: REGISTRO E IMPLICAÇÕES
Mielke, Erica Costa; Negrelle, Raquel Rejane Bonato; Cuquel, Francine Lorena & Lima, Walquiria Pizatto

Resumo

A maioria das Unidades de Conservacao (UCs) de Curitiba (PR, Brasil) esta contaminada por especies arboreas exoticas invasoras (AEIs). Mas nao existem estudos que evidenciem seu impacto e manejo apropriado. Os objetivos dessa pesquisa foram avaliar a participacao das AEIs e as implicacoes e manejo da AEI de maior importancia estrutural na composicao floristica-estrutural do Parque da Barreirinha, um remanescente de Floresta com Araucaria. Foram avaliadas quatro unidades amostrais, com area total de 1600 m2 representando aproximadamente 4% da area total do macico vegetal. Foram amostrados 354 individuos arboreos, com DAP ≥ 15 cm, e calculados, para cada especie amostrada, os parametros de frequencia relativa, densidade relativa, dominancia relativa e valor de importancia. Foram identificadas 29 familias, 43 generos e 57 especies, sendo tres AEIs. A sustentabilidade e a integridade desta UC podem estar comprometidas devido a presenca de Pittosporum undulatum check for this species in other resources Vent. (pau-incenso), especie de maior valor de importancia estrutural, alta densidade e frequencia. Pelas caracteristicas botanico-ecologicas do Pittosporum undulatum, a opcao de remocao de individuos adultos deve ser considerada com muita cautela.

Abstract

The majority of the Conservation Units (CUs) of Curitiba (Parana state, Brazil) are plagued by invasive alien tree species (IATs). However, no studies have been carried out to evaluate their impact or to determine the appropriate management techniques. The objective of this study is to evaluate the participation of IATs and the implications and management of the most significant species causing major structural change in the floristic-structural composition of eBarreirinhaf Park, a remnant of Araucaria Forest. Four plots were evaluated in a total area of 1600 m2 representing approximately 4% of the total area of the forest. A total of 354 individual trees were sampled with a diameter of . 15 cm, and for each species sampled, parameters were calculated of the relative frequency, relative density, relative dominance and the importance value. It was possible to identify 29 families, 43 genera and 57 species, three of which were IATs. The sustainability and integrity of this Conservation Unit can be threatened by the presence of Pittosporum undulatum check for this species in other resources (Sweet Pittosporum), the species with the greatest structural importance value, high density and frequency. Possible management strategies for the Pittosporum undulatum species are presented.
