Abstract &#x2013; 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 Paran&#xE1;, 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 &#x2013; O objetivo deste trabalho foi avaliar os m&#xE9;todos galharia, cobertura
por pl&#xE1;stico preto, herbicida e poleiro artificial na regenera&#xE7;&#xE3;o natural de
esp&#xE9;cies nativas em &#xE1;rea com pastagem de Urochloa. O experimento foi
conduzido entre fevereiro de 2014 e fevereiro de 2016 na Floresta Ombr&#xF3;fila
Densa, no munic&#xED;pio de Morretes, no estado do Paran&#xE1;, Brasil. Os tratamentos
foram: herbicida, herbicida + poleiro, cobertura por pl&#xE1;stico preto, cobertura
por pl&#xE1;stico preto + poleiro, galharia + herbicida, galharia + herbicida +
poleiro e testemunha. As avalia&#xE7;&#xF5;es foram realizadas aos 4, 8, 12, 18 e 24
meses ap&#xF3;s a instala&#xE7;&#xE3;o do experimento, com contagem e identifica&#xE7;&#xE3;o das
esp&#xE9;cies lenhosas regenerantes e estimativa visual do percentual de cobertura
por herb&#xE1;ceas. Inicialmente, a galharia e a cobertura por pl&#xE1;stico preto
reduziram as gram&#xED;neas Urochloa; entretanto, com o decorrer do tempo,
esse efeito se perdeu devido ao r&#xE1;pido crescimento das gram&#xED;neas das bordas
para o centro das parcelas. O uso de poleiros nos tratamentos n&#xE3;o possibilita
incremento significativo de outras esp&#xE9;cies, em raz&#xE3;o da perman&#xEA;ncia das
condi&#xE7;&#xF5;es inibidoras ao estabelecimento das pl&#xE2;ntulas. O herbicida &#xE9; eficiente
para remover as gram&#xED;neas; contudo, o recrutamento de esp&#xE9;cies lenhosas
somente &#xE9; satisfat&#xF3;rio com o uso de poleiros para atra&#xE7;&#xE3;o da fauna dispersora. 
Para o sucesso da restaura&#xE7;&#xE3;o ecol&#xF3;gica em pastagens, h&#xE1; a
necessidade de elimina&#xE7;&#xE3;o local das gram&#xED;neas Urochloa.
