Resumen
The drastic fragmentation and degradation of forests resulting from illegal logging caused significant losses to the Brazilian flora. Thus, studies that seek to understand tree communities are extremely important to maintain the conservation of these areas. The aim of the present study was to survey the species composition and structure of the tree community of three Municipal Natural Parks occurring in the Ombrophilous Mixed Forest, in the municipality of Bituruna, PR, southeastern Paraná. A total of 70 plots measuring 25 x 2 m were installed, distributed in a systematic way, every 100 m apart, in a total sample area of 0.35 ha. In the Antonio Necy Cherubini and Lidia Abruzzi Cherubini Municipal Natural Park (PANCLAC) it was found that the highest VI was of Solanum mauritianum with 19%, H’ of 2.35 nats.ind and J of 0.77. In the Municipal Natural Park Lino Cherubini and Elsa Tarrasconi Cherubini (PLCETC), the highest VI was of bamboo with 18.72%, H' of 2.58 nats.ind and J of 0.75, and in the Natural Park Municipal Gelmi Cherubini and Zulema Anna Frizon Cherubini (PGCZAFC) the highest VI was from Dicksonia sellowiana with 19.58%. H’ is 2.75 nats.ind and J is 0.78. In the floristic survey, 219 species from 60 families were identified. The families that presented the greatest richness in terms of species were Asteraceae, Lauraceae and Myrtaceae, both in the phytosociological and floristic survey. Among the identified species, four are on the Official List of Endangered Species, and were classified as "vulnerable" (VU) (Cedrela fissilis; Neocabreria malachophylla; Ocotea catharinensisand Rudgea jasminoides) and three "endangered" (EN) of extinction (Araucaria angustifolia, Dicksonia sellowianaand Ocotea porosa), by the list of the National Flora Center (CNCFLORA, 2012). Araucaria angustifoliawas classified as “Critically Endangered” (CR) for extinction by the International Union for Conservation of Nature list (IUCN, 2021).
