Abstract

The present study aimed to verify the floristic composition in two distinct areas: reforestation with Eucalyptus and degraded area subjected to fire. Plots of 0.5 m x 0.5 m were demarcated, dis-tributed in transect in the two analyzed areas, were carried out. The analyzed aspects were the following: plant species variability, fresh mass, dry mass and litter. The results showed that the cultivation with eucalyptus was the one with the highest amount of plant species, reaching the number of 17 species, while in the degraded area 11 different species were found. In terms of fresh and dry mass, there was no observed difference between areas. In relation to litter, the cul-tivation with eucalyptus had the highest weight. It is concluded that the cultivation with euca-lyptus showed the highest number of plant species, the highest amount of mulch and green mass; as for the dry mass, there was an equivalence in the results of the two areas.

Highlights

The biodiversity of plant species is very important, with environmental impacts, affecting ecosystem services and ecological processes [1,2,3]
Eucalyptus reforestation had a greater number of species when compared to the fragment of degraded Atlantic forest (Figure 1-C)
In an already consolidated eucalyptus reforestation, such as the area collected in this study, there is a greater entry of sunlight between the treetops, favoring the development of a greater number of species in addition to a longer period for the species to establish themselves, three years against one year of the degraded area

Summary

Introduction

The biodiversity of plant species is very important, with environmental impacts, affecting ecosystem services and ecological processes [1,2,3]. The affected ecosystem needs time to regeneration and may not reach the diversity that previously existed in the place [1,5]. Another threat to diversity is the cultivation of species of economic interest because, in these areas, the vegetation is completely removed and its growth controlled so as not to interfere with the development of the culture of interest [6]. Its purpose is to be used in the civil industry and in the manufacture of cellulose as a raw material in paper production [6]
