Unexpected effects of pigeon-peas (Cajanus cajan) in the restoration of rupestrian fields

Abstract: -Several degraded areas can be found along the Highway MG-010 that crosses the Espinhaço Mountain Biosphere Reserve in the Brazilian state of Minas Gerais. Restoration by planting the legume Cajanus cajan was implemented in some of these areas. The present study compares plant species richness, diversity, abundance, equitability, similarity, and soil composition between restored and non-restored areas, in an attempt to evaluate the effectiveness of the use of C. cajan in the restoration process in the mountain… Show more

“…Thus this species can be used to replace or reduce the use of exotic and invasive species, which has caused much damage to rupestrian grasslands (Barbosa et al 2010;Hilário et al 2011;Fernandes et al 2015;2016).…”

“…If the results obtained with P. mediterranea are confirmed in field evaluations, it is possible that this species could be used to replace other exotic and invasive legumes commonly used in the revegetation of degraded areas in Brazil, and which have caused problems such as limitations to ecological succession and the invasion of adjacent areas (Hilário et al 2011;Fernandes et al 2015).…”

“…O feijão-guandu foi usado para facilitar o processo de sucessão na restauração da rodovia MG-010 no ano de 2004, a fim de criar sombra para espécies nativas e também fornecer cobertura vegetal para o solo suscetível à erosão. Todavia, Hilário et al (2011) mostraram que vários anos após a introdução de Cajanus cajan ainda se observava que, além de ela não fornecer sombra para outras espécies nativas nem proporcionar cobertura vegetal para as áreas erodidas, impedia a colonização natural das áreas restauradas. Além disso, estes autores mostraram que tal espécie começou a propagar-se além da área onde foram plantadas, invadindo as áreas adjacentes à rodovia.…”

“…Algumas espécies introduzidas já adentraram e se estabeleceram nos campos rupestres (Hilário et al, 2011). Algumas delas podem ser encontradas a mais de 2 km a partir da borda da rodovia asfaltada, incluindo A. fastigiatum, M. pigra, M. minutiflora, U. brizantha, A. satureioides, C. cajan, C. pallida e C. spectabilis, entre muitas outras.…”
