Controlled logging and repeated refinement are the corner-stones of the system, which is based on the harvesting of a restricted amount of about 20 m3 of quality timber from each hectare, once about every 20 years, in a well-controlled selection felling operation. Selection felling is followed by refinement using arboricides, three times during the cycle (in year 0, year 8 and year 16), to release commercial species, and provide economically sufficient increment. The main principles underpinning the system are minimum interference and maintenance of a high level of biomass to prevent leaching of nutrients from the ecosystem.

The Celos Management System has been developed following four large experiments, carried out in Suriname for more than a decade, and holds promise as an economically and ecologically viable approach to managing highly mixed forest growing on chemically very poor soils, in areas of low population density.
