Rehabilitation of Abandoned Quarry Sites in Trinidad, W.I.

Paul Comeau


Two sand and gravel quarry sites, one a surface and the other a deep excavation, and a hillside limestone quarry were studied in northern Trinidad with the purpose of recommending rehabilitation measures using native plant species. In addition, two control sites were examined, a rehabilitated hillside quarry, and an abandoned site where natural regeneration of plants has taken place.

The environmental impact of these rehabilitation options is examined.
