Invasive Species Compendium

Detailed coverage of invasive species threatening livelihoods and the environment worldwide

Abstract

Participation of the indigenous vs. alien herbaceous species to the constitution of vegetal layer on the Bozanta Mare tailing ponds.

Abstract

This study explored the distribution of different species of native and alien herbaceous species on the tailing pond Bozânta Mare (Maramureș county in NW Romania) and the differences in heavy metal uptake in the roots and shoots relative to: 1. herbaceous species; 2. differential metal uptake and variation within single-species; 3. metal content of soil substrate. In 2007-2009 the contribution of native and alien species to the herbaceous layer forming, were studied on the Bozânta Mare tailing pond, resulted after heavy metal extraction process. The heavy metals found at elevated level in the herbaceous species included for environmental interest are: Pb, Cu, Ni, Zn, Co, Cd, Fe, Cr, Mn, Na, K. Also, the aim of this research is to evaluate the impact of the native vs. alien species presence in the colonization process on the tailing pond.
