Abstract
Spontaneous recovery and the structure of plant community after agriculture use and fire in grasslands in the Vila Velha state park, South Brazil
Highlights
The subtropical grasslands in South Brazil known as Campos Gerais are the main vegetation in the highlands along the topographic slope called Escarpa Devoniana, in the State of Paraná
South American native grasslands probably evolved under a disturbing system of grazing and fire[1] that supposedly selected species since pre-historic ages[2]
This paper aims to contribute to the fire prescription discussion as well as to restoration programs.[14,18]
Summary
The subtropical grasslands in South Brazil known as Campos Gerais are the main vegetation in the highlands along the topographic slope called Escarpa Devoniana, in the State of Paraná. South American native grasslands probably evolved under a disturbing system of grazing and fire[1] that supposedly selected species since pre-historic ages[2]. Their plant composition and structure are well known[3,4,5,6,7,8,9,10] as well as their response to anthropogenic impacts such as grazing and touristic activities.[11,12] there are few data about spontaneous recovery in abandoned arable land and after fires.[13,14,15,16]. The effects of the conversion of grasslands to other land uses in subtropical grasslands are poorly understood
