Abstract – The objective of this work was to evaluate the effect of brushwood,
black plastic mulch, herbicide, and artificial perch on the natural regeneration
of native species in Urochloa grassland. The experiment was conducted
between February 2014 and February 2016 in the Dense Ombrophilous Forest,
in the municipality of Morretes, in the state of Paraná, Brazil. The treatments
were: herbicide, herbicide + perch, black plastic mulch, black plastic mulch +
perch, brushwood + herbicide, brushwood + herbicide + perch, and a control
treatment. The evaluations were carried out at 4, 8, 12, 18, and 24 months after
the installation of the experiment, by counting and identifying regenerating
woody species and estimating visually the percentage of herbaceous coverage.
Initially, brushwood and black plastic mulch reduced the Urochloa grasses;
however, this effect was lost over time due to the rapid growth of the grasses
from the edges to the center of the plots. The use of perches in the treatments
does not allow a significant increase of other species because of the continued
inhibiting conditions for the establishment of seedlings. The herbicide is
effective in removing the grasses; however, the recruitment of woody species
is only satisfactory when perches are used to attract the dispersing fauna. For
a successful ecological restoration of pastures, there is a need for the local
elimination of Urochloa grasses.


Index terms: artificial perch, black plastic mulch, brushwood, herbicide,

Resumo – O objetivo deste trabalho foi avaliar os métodos galharia, cobertura
por plástico preto, herbicida e poleiro artificial na regeneração natural de
espécies nativas em área com pastagem de Urochloa. O experimento foi
conduzido entre fevereiro de 2014 e fevereiro de 2016 na Floresta Ombrófila
Densa, no município de Morretes, no estado do Paraná, Brasil. Os tratamentos
foram: herbicida, herbicida + poleiro, cobertura por plástico preto, cobertura
por plástico preto + poleiro, galharia + herbicida, galharia + herbicida +
poleiro e testemunha. As avaliações foram realizadas aos 4, 8, 12, 18 e 24
meses após a instalação do experimento, com contagem e identificação das
espécies lenhosas regenerantes e estimativa visual do percentual de cobertura
por herbáceas. Inicialmente, a galharia e a cobertura por plástico preto
reduziram as gramíneas Urochloa; entretanto, com o decorrer do tempo,
esse efeito se perdeu devido ao rápido crescimento das gramíneas das bordas
para o centro das parcelas. O uso de poleiros nos tratamentos não possibilita
incremento significativo de outras espécies, em razão da permanência das
condições inibidoras ao estabelecimento das plântulas. O herbicida é eficiente
para remover as gramíneas; contudo, o recrutamento de espécies lenhosas
somente é satisfatório com o uso de poleiros para atração da fauna dispersora. 
Para o sucesso da restauração ecológica em pastagens, há a
necessidade de eliminação local das gramíneas Urochloa.
